A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is potted in the same type of soil and receives the same amount of sunlight and water each day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all.
1. In the experiment described in the scenario, what's the variable?
A. The amount of water each plant receives
B. The amount of sunlight each plant receives
C. The type of soil in which each plant is potted
D. The type of music each plant listens to
Answer:
D. The type of music each plant listens to
Explanation:
The question indicates each plant is in the same soil (so cannot be C), received the same amount of sunlight (so cannot be B) and the same amount of water (cannot be A).
However, each plant is exposed to a different type of music, one is listening classical, another rock and another country music.
So, the only variable in here is the type of music each plant listens to.

Steady state theorists support the perfect cosmological principle, which suggests the universe looks the same from all directions, but over time.
Answer:
The correct answer or fill in would be- but Change and evolve over time.
Explanation:
The perfect cosmological principle is a extended version of the cosmological principle. The perfect cosmological principle says that the universe is look same from all directions but can be change and evolve with time.
Steady state theory supports this theory as it also says that universe is expanding but also maintain its density even though it continuously creates stars and galaxies but still look same.
Thus, the correct answer is - but Change and evolve over time.
Final answer:
The Steady State Theory, an alternative to the Big Bang, proposes an unchanging universe with continuous creation of new matter to maintain constant density, but was disproved by observations like the Cosmic Microwave Background Radiation.
Explanation:
The Steady State Theory is a cosmological model that was a popular alternative to the Big Bang theory in the mid-20th century. Developed by Fred Hoyle, Hermann Bondi, and Thomas Gold, the Steady State Theory posits that the universe is expanding, and as galaxies move further apart, new matter is continuously created to fill the resultant space, maintaining a constant density. This theory supports the Perfect Cosmological Principle, suggesting that the universe is homogeneous and isotropic not only in space but also in time, avoiding the need for a universe with a beginning and working around the issue of heat death due to exponential expansion.
However, key observations such as the Cosmic Microwave Background Radiation and evidence of the evolution of galaxies and large-scale structures have considerably weakened the support for the Steady State Theory. The CMB's perfect blackbody spectrum across all directions directly contradicts the predictions of Steady State cosmology and aligns with the Big Bang model, ultimately leading to the theory falling out of favor among cosmologists.

The virus that relies on molecules called reverse transcriptase to build DNA from its RNA molecules is RetroVirus.
Explanation:
Retrovirus is a type of virus that is made up of RNA. When it attacks a cell, RNA is inserted into the host cell. Retrovirus has a special enzyme called reverse transcriptase that is used to create DNA by using RNA as template. It inserts its RNA into host genome and changes the genetic information.
Why is it important for an organism to maintain homeostasis
Answer:
If not they could die.
Explanation:
Some organisms cannot survive in harsh weather conditions so they must balance homeostasis to survive.
Maintaining homeostasis is essential for an organism's survival. It serves to keep internal conditions optimal and stable, regardless of external changes. Disruption of homeostasis can lead to disease.
Explanation:It's crucial for an organism to maintain homeostasis to ensure optimal and stable conditions within its internal environment, regardless of external changes. Homeostasis involves multiple processes that keep conditions within certain boundaries, or set points, to allow the organism to function effectively. For instance, humans maintain a body temperature of approximately 37 degrees Celsius, despite the influence of external temperatures. Similar processes control glucose levels, water balance, and pH balance in the blood. Failure to maintain homeostasis can lead to disease or, in severe cases, death.

What allows for some organisms in a population to have an
increased survival rate over other organisms of the same
species?
Answer:
Their genetic appearance
Explanation:
Some organisms have a different variety than other organisms of the same species. This is where natural selections come into play. Predators may favor one variety over the other, giving some organisms a increased survival rate.
Hope this helped!!
Final answer:
The increased survival rate in some organisms over others within the same species is attributed to genetic variability, beneficial traits, and natural selection. Mutations lead to new traits and those beneficial for survival and reproduction become more common in the population.
Explanation:
The key factors include genetic variability, the presence of certain beneficial traits, and the process of natural selection. Organisms within a population have genetic differences, and some of these genetic variations result in traits that offer a survival advantage in specific environmental contexts. For example, better camouflage might protect prey species from predators, or a more efficient metabolism may allow for survival in scarce food conditions.
Mutations are changes in the genetic code that can lead to new traits in a population. Beneficial mutations that occur in the gametes can be passed down to offspring, thereby contributing to the evolutionary adaptation of the species. Over time, individuals with advantageous traits tend to survive and reproduce more successfully, which means these traits become more common in the population. This is the essence of natural selection: the differential survival and reproduction of organisms based on their genetic traits.

What could be achieved by DNA profiling using gel electrophoresis?
Answer:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.

Some steps in cell division are shown below:
1. Chromosomes condense and pair up
2. Segments of DNA of sister chromatids twist and cross
3. Exchange of DNA occurs between chromosomes
4. Four daughter cells are created that are haploid
Which of the following steps is least likely to occur during meiosis 1?
Step 1
Step 2
Step 3
Step 4
Answer:
Step 4
Explanation:
Bcoz only 2 haploid cells are formed at the end of meiosis 1st...at the end of meiosis 2nd.. 4 haploid cells formed
Answer:
The correct answer would be step 4.
Meiosis I is the reduction division which results in the formation of two haploid daughter cells from a single parent cell.
It includes prophase I, metaphase I, anaphase I, and telophase I.
During prophase I, first DNA gets condense to form chromosomes. Each chromosome consists of two sister chromatids. Then the event of crossing-over (exchange of genetic material) takes place.
By the end of meiosis I, the homologous chromosomes are separated into two daughter cells.
Meiosis II results in the formation of four haploid daughter cells.

Environmental factors can determine if a genetic trait becomes a health issue.
c.
Environmental factors are determined by genetic traits.
d.
Environmental factors have no influence on genetic traits.
Please select the best answer from the choices provided
Answer:
a. Environmental factors determine all genetic traits
Explanation:
The environmental factors are the basis for the evolution of the organisms. The environment is where the organisms live, so in order for them to be able to survive, they need to evolve traits in accordance to the environment, traits that would be advantageous for their survival. This leads to changes in the genes of the organisms, changes where the genes that contribute to easier survival remain, new advantageous ones develop, while the ones that are a limiting factor are slowly removed from the gene pool. This of course takes longer period of time and it happens gradually.

What condition is required for fermentation to occur?
The condition required for fermentation to occur is when the oxygen levels within a cell are too low for aerobic respiration.
Further Explanation:Cellular respirationThis is the process by which food substances such as glucose are broken down to yield energy in the form of ATP for the cells. The energy is then sued to drive cellular activities such as transport and cell division.Cellular respiration is classified into two;Aerobic respiration.Aerobic respiration is a type of respiration that takes place in living organisms in the presence of oxygen gas.The process involves the breakdown of organic compounds such as glucose to yield energy in the form of ATP and carbon dioxide together with water as byproducts.Anaerobic respiration/Fermentation Anaerobic respiration on the other hand is a type of respiration that occurs in absence of oxygen gas or in presence of low levels of oxygen gas in the cells.It involves the breakdown of organic compounds to form small amount of energy in the form of ATP and ethanol or lactic acid as byproducts.Anaerobic respiration/Fermentation occurs in two stages;Glycolysis; One glucose molecule is broken down to pyruvate and two molecules of ATP are formed.Fermentation; This is the second stage of anaerobic respiration, pyruvate from glycolysis can undergo various steps depending on the living organism. It can be converted to ethanol or lactic acid together with carbon dioxide.Keywords: aerobic respiration, anaerobic respiration, Glycolysis, Fermentation.
