Why did the theory of light change overtime?
A.The theory was too old and needed to be updated
B.new scientists did not agree with the older theory
C.the scientific question changed, so the theory had to change
D.repeated experimentation introduced new discoveries
Answer:
it is two answers (A and d)
Explanation:
If we keep the same theory of light today we wouldn't be advanced as we are now so yes the old theory had to get updated or plain or replaced with a newer one, D is also correct because if you repeat something you will find out new things from the first time you tried it out.
Answer:
D.repeated experimentation introduced new discoveries
Explanation:
The theory of light began in antiquity with the Greek philosophers who believed that light was formed by tiny particles that spread in the ambience at high speed, today we know that this is not true, through the realization of innumerable experiments. This theory was believed for years, until through several experiments that took place through the session, it was allowed to make increasingly accurate discoveries about who were able to change this theory several times over time. In fact, through more controlled experiments, this change in light may change again.

Which of the following is the MOST accurate regarding the speed of light?
A) The speed of light depends on the color of light that we see.
B) The speed of light is constant in all media at all times and places.
C) The speed of light can change as it moves through different materials.
D) The speed of light is only affected by the brightness of the light.
Answer:
C
Explanation:
The speed of light can change as it moves through different materials
Option C is correct; the speed of light can change as it moves through different materials, even though it remains constant in a vacuum and is not affected by the light's color.
The most accurate statement regarding the speed of light is that it can change as it moves through different materials, making option C the correct answer. The speed of light in a vacuum, denoted as c, is a constant value of approximately 3 × 10⁸ m/s, and is one of the fundamental constants of physics. This means that regardless of the motion of the source or the observer, the speed of light in a vacuum remains the same. However, when light passes through different materials, such as air, water, or glass, its speed is affected by the refractive index of the material. For instance, light travels slower in glass than in air. While the speed is constant in a vacuum and does not depend on the frequency or wavelength of light (thus, not on the color), it does vary in materials with different refractive indices.

You go to the doctor, only to find out that you have a case of Strep Throat. Your
doctor explains this is caused by a bacterium called Staphylococcus pyogenes.
Based on the underlined portion of this bacterium's genus, what shape are the
bacteria that cause strep throat?
Ofilamentous
Orod
O spherical
Ospiral
Answer:
the rod shaped bacteria
Explanation:
The fact that this is a Gram-positivebacterium means it has a very thick cell wall compared to a Gram-negativebacterium. Since this bacterium is known as a 'coccus', that automatically means it has a round shape, as opposed to a rod-shaped bacteria.
The underlined portion of the bacterium's genus, "Staphylococcus pyogenes," indicates that the bacteria that cause strep throat have a spherical shape. The correct answer is 3. "spherical."
Bacteria are single-celled microorganisms that play a significant role in various ecosystems. They are among the most abundant and diverse organisms on Earth and can be found in almost every environment, including soil, water, air, and even within the human body.
The term "Staphylococcus" refers to bacteria that typically form clusters resembling grapes, which is a characteristic of spherical or cocci-shaped bacteria. Strep throat, however, is caused by a different bacterium called Streptococcus pyogenes, which also belongs to the cocci-shaped bacteria.
The term "Staphylococcus" in the question seems to be an error, and the correct genus for the bacteria causing strep throat should be "Streptococcus." Therefore, the correct answer is 3. "spherical."

Lakes can be formed as a result of what type of weathering? Select ALL that apply.
Glacier movement over the crust
Upwelling from the water table
Formation of a terminal moraine
Trapped acidic water dissolving large amounts of limestone
Answer:
Options A and D are correct:
Glacier movement over the crustTrapped acidic water dissolving large amounts of limestoneExplanation:
Glacial lakes: It has been well reported that glacial erosion often leads to the development of lakes. When a glacier moves, it erodes the sediments which lead to the formation of depressions. In later years, these depressions are filled with water and form a lake. This is why these lakes are recognized as "glacial lakes".
Lakes formed by dissolving limestone: We know that acids can dissolve the limestone (CaCO3) very quickly. Therefore, if acidic water traps in an area where the bed-rock is made up of limestone, the water will dissolve it and form a depression. The acidic water could stay the same place forming acidic lakes or could be replaced with normal water later on due to hydrogeological processes.

Variations within species are the result of ______ and ______shuffling.
Answer:
Variations within species are the result of mutations and genetic shuffling.
Explanation:
Mutations arise from any changes which occur in the DNA of an organism. Most mutations can be heritable whereas there are some mutations which are not heritable. Mutations can cause wide number of changes within a species.
The shuffling of genes during sexual reproduction also causes variations in species. Crossing over and independent assortment are the two phenomena which occur during meiosis and allow variations among organisms of the same species.
cyanide is a poison that prevents mitochondria from using oxygen. as a result, the mitochondria cannot produce what?
Answer:
the mitochondria would not be able to produce energy
Explanation:
"the mitochondria is the powerhouse of the cell"
Final answer:
Cyanide poisoning inhibits the enzyme cytochrome c oxidase in the electron transport chain, preventing ATP synthesis and increasing the pH of the intermembrane space due to reduced proton pumping.
Explanation:
Cyanide is a poison that has a high affinity for the enzyme cytochrome c oxidase, which is an essential component of the electron transport chain in mitochondria. The enzyme's inhibition by cyanide prevents the transport of electrons from cytochrome c to oxygen, disrupting the electron transport chain and halting ATP synthesis.
As a result of cyanide poisoning, the electron transport chain cannot create an electrochemical gradient across the mitochondrial membrane, which is necessary for ATP production through oxidative phosphorylation. Thus, ATP synthesis stops, which can lead to cellular energy deficit and ultimately cell death.
Furthermore, due to the disruption of the electron transport chain, the pH of the intermembrane space would increase as proton pumping by the chain's complexes is halted. This decrease in the proton gradient further prevents ATP synthesis.
reaction that does not require oxygen
Answer:
The reaction is called Anaerobic respiration.
Explanation:
The reaction that doesn't require oxygen is known as Anaerobic reaction. Anaerobic respiration is the ability of an organism to produce energy in the form of Adenosine Triphosphate (ATP) without using oxygen. Instead, sulfate, nitrate or sulfur is used. To break down the equation above, organisms that use anaerobic respiration to produce energy start with glucose. Glucose is sugar, and the same sugar from the photosynthesis equation 6CO2 + 6H20 = C6h1206 + 6 02. Organisms take glucose, and through the electron transport chain, produce ethanol or lactic acid, CO2, and ATP.

what passes electrons in the etc
There are different electron carrier carriers in the mitochondria that helps in transferring electron in the Electron Transport Chain.
Explanation:There are different reactions like Kreb's Cycle and others going in the mitochondrial matrix. These reactions synthesize different reduced proton like NADH₂ and FADH₂. These reduced carriers then go to the inner mitochondrial membrane where there are different electron carriers - four in types namely complex 1,2, 3,and 4 respectively. NADH₂ goes to complex 1 and release the Hydrogen and gets back to NAD and FADH₂ goes to complex 2 and release Hydrogen and gets back to FAD.
The electron that is released to the complex 1 goes to complex 2 and then to Q complex. Then it goes to complex 3 and 4 respectively where the final electron is taken by the oxygen atom to produce oxide ion.

. it can reproduce
. it does not grow or develop
. it does not maintain homeostasis
it can adapt to its surroundings
. it uses energy
Based on these observations, is this alien living or not?
it is living because it is made of cells, uses energy, and reproduces
it is living because it has all the characteristics of life
it is non-living because it does not have all the characteristics of life
Answer:
The answer is A, it is living because it is made of cells, uses energy, and reproduces.
Explanation:
The alien body exhibits several characteristics of life such as cellular structure, reproduction, and energy use. However, it lacks two crucial characteristics: growth and maintaining homeostasis. Therefore, it cannot be definitively classified as a living organism based on the observations.
Explanation:The concept of life is defined by several key characteristics that most living entities possess, these include growth and development, reproduction, use of energy, cellular structure, adaptation to the environment, and maintaining homeostasis. Given the observations for this alien body; its composition of cells, ability to reproduce, adapt to its environment and use energy indicates that it possesses many attributes of a living organism. However, its inability to grow and develop and lack of homeostasis complicates the classification of this alien as a living organism. In most definitions of life, homeostasis and growth are key. Therefore, strictly speaking, even though this alien exhibits some characteristics of life, it is missing others, namely growth and homeostasis and cannot be classified definitively as living or non-living based on the observations given.

What are the two specific concerns of species diversity?
Species diversity is concerned with both
Species diversity concerns the variety of species and genetic variability within those species, which is crucial for adaptation and ecosystem services. Preservation efforts aim to mitigate threats like habitat destruction, climate change, and invasive species.
Explanation:The two specific concerns of species diversity are related to the variety and variability within and among species and between ecosystems. Firstly, it involves the diversity of species themselves, which is an index of how many different species are present in a given ecosystem or the Earth as a whole. Estimates suggest Earth inhabits between 5 to 30 million species, though the exact number remains uncertain. The second concern is genetic diversity, which refers to the variation in genes within these species. This range of genetic material is critical for adaptation and the success of species in diverse environments.
Genetic diversity is fundamental for a species' adaptation to local conditions and its potential to cope with environmental changes. It also affects our agriculture as different crop varieties, for instance, are often adapted to different growing conditions. The preservation of biodiversity is thus crucial for maintaining the ecosystem services that support human life, such as pollination, nutrient cycling, and pest control.
Increasingly, environmental and conservation efforts are directed towards protecting this biodiversity by reducing threats like habitat loss, climate change, and the introduction of invasive species, while promoting sustainable resource use and habitat restoration. International treaties and laws such as CITES and the Endangered Species Act are in place to protect this diversity. Nonetheless, maintaining biodiversity requires a multifaceted approach, including preservation strategies and changing human behaviors and beliefs.

Where do marine scientists get the ethical standards for their profession and what kind of values do they include?
Answer:
Explanation:
The ethical standard was accepted by the Society in the 2013 mid-year ballot. This Code states 17 guiding principles aimed at assisting the Society.
Some of the ethical issues include the potential for data fabrication/ falsification,
conflicts of interest, human subjects violations, working with scientific uncertainty and values conflicts in marine conservation.
Final answer:
Marine scientists acquire their ethical standards from scientific ethics, philosophical discussions, religious and environmental ethics, and community norms. These standards emphasize the minimization of harm to organisms and ecosystems, as well as unbiased research. Ethical reasoning features in education and policy to guide practitioners in morally complex situations.
Explanation:
Origins of Ethical Standards in Marine Science
Marine scientists derive their ethical standards from a variety of sources including scientific ethics, philosophical discourse, and environmental considerations. These standards aim to protect humans, animals, and ecosystems from undue harm while promoting research that is free from bias. Principles of ethics such as compassion, humility, respect, coexistence, and sustainability guide interactions with marine life, with an increasing focus on moral considerations as we learn more about marine cognition and consciousness.
Ethical dilemmas, intrinsic and extrinsic values, and the application of ethical reasoning are core components within the marine science field. This includes the management of fisheries and the conservation of rare and endangered species, where ethical assumptions can significantly influence policy and practice. Additionally, religious and environmental ethics contribute to shaping the values and norms that marine scientists may hold, especially when pondering grand questions about humanity's relationship with the ocean and its inhabitants.
To foster ethical conduct, the incorporation of ethical reasoning is advocated in curricula, major meetings, and agency operations. Emotion plays a critical role in shaping moral judgments, which is why the engagement of both hearts and minds is encouraged in ethical deliberations. This holistic approach helps marine scientists navigate complex ethical landscapes in their work.
How are humans connected to photosynthesis? *Include the words: autotroph, cellular respiration, energy, photosynthesis*
Photosynthesis and cellular respiration interconnect plants and human beings.
Explanation:
Plants prepare their own food and are autotrophs. Humans depend on autotrophs both directly and indirectly for food and are heterotrophs.
Heterotrophs consume both plants and animals to get energy
Photosynthesis: reactants - sunlight, carbon dioxide and water; products – sugar, oxygen
Cellular respiration: reactants - glucose and oxygen; products – water, carbon dioxide
Carbon dioxide (end product) released due to cellular respiration by the humans enters the atmosphere and is absorbed by the plants which become a reactant in photosynthesis.
Oxygen (end product) released due to photosynthesis by plants enters the atmosphere and is inhaled by human beings and becomes a reactant in cellular respiration.

6. Telophase I
7. Prophase II
8. Telophase II
Explanation:
The phases of meiosis can be remembered using the acronym PMAT
The first stage (during Meiosis I), is called Prophase I. During this phase, the chromosomes condense and become visible and the nuclear envelope breaks down. Homlogous chromosomes pair up and crossing over occurs, meaning they exchange bits of DNA.
Next, Metaphase I occurs, in which the pairs of chromosomes move to the centre (equator) of the cell and line up long the equator.
Anaphase I then occurs, where special microtubules called spindle fibres pull the homologous chromosomes to opposite sides of the cell.
The next step is called Telophase I, in which the chromosomes gather at the poles, spindle fibres degrade, the cytoplasm divides and a new nuclear membrane forms - producing 2 daughter cells.
The cell now enters Meiosis II, the first stage of which is Prophase II. During prophase II, the chromosomes condense, the nuclear envelope breaks down again and a new spindle apparatus forms.
The next stage is Metaphase II, during which the chromosomes (now not in their homologous pairs as these have already been divided) are aligned in the centre of the cell, the equator.
The next stage is Anaphase II, in which the chromatids are pulled to opposite ends of the two daughter cells by the spindle.
The final stage is Telophase II, where 4 haploid daughter cells are formed after the reformation of the nuclear membranes, division of the cytoplasm and the chromatids uncoil.

It was passed to the individual by a gamete from the father.
Half of the individual's cells descend from the father's gamete.
Half of the individual's nuclei descend from the nucleus of the father's gamete.
Answer:
B. It was passed to the individual by a gamete from the father.
Explanation:
DNA is transferred to the next generation via gametes, which are produced during meiosis. During meiosis, half of the genetic material is transferred from parent cell to their gametes. Therefore, among the given options, only B is correct.
Option A is not correct because it talks about somatic cells; whereas, in somatic cells, genetic material is not transferred half rather duplicate first and then a complete duplicated set of genetic material is transferred.
Option C is also not correct because only one gamete (sperm) fertilizes the egg. Hence, not half of his cells descend from father gamete. Similarly, option D is also incorrect because it is not possible to descend half of the nuclei from the father to the offspring.
Which of the following is NOT a known side-effect of alcohol on hormonal balance?
Estrogen-androgen imbalance in males
Reduction of fertility in women
Early menopause in women
Answer:
Estrogen-androgen imbalance in males
Explanation:
Estrogens and andogens are hormones. Estrogens are produced by the body in greater amounts in females. They are necessary for normal sexual development of the female and for regulation of the menstrual cycle during the childbearing years. Androgens are produced by the body in greater amounts in males.
Final answer:
Early menopause in women is not a known side-effect of alcohol on hormonal balance. Alcohol consumption leads to hormonal imbalances that may affect fertility, but menopause is mainly influenced by the natural aging process.
Explanation:
The question pertains to the side effects of alcohol on hormonal balance. Among the given options, the assertion that alcohol can lead to early menopause in women is NOT a known side-effect. While alcohol does affect hormonal balance, leading to issues such as estrogen-androgen imbalance in males and negatively affecting female fertility, early menopause is more directly related to the aging process and the decline of ovarian function, rather than alcohol consumption. Menopause involves a decrease in estrogen and progesterone levels as a result of ovaries becoming less sensitive to gonadotropins due to aging.
