A. can use different modes of movement to move themselves away from any medicine that's harmful to them.
B. can reproduce either sexually or asexually to avoid some types of medicine.
C. can change their cell walls to develop antibiotic resistance.
D. and animals are closely related and are both eukaryotic. Many medicines that treat fungal infections are also harmful to animal cells.
Answer:
The answer is D
Explanation: This is because fungus are Eukaryotic unlike bacteria.
Answer:
The correct answer will be option D.
Explanation:
Fungal infection are the infections caused by the fungi which are less common than infection caused by bacteria.
Fungi attack animals by direct colonizing and destroying the tissues and result in mycosis. Many fungal infections occur on the animal's skin.
Although rare, they are very difficult to treat as they are closely related to eukaryotic organisms and the compound that kill the fungi also harms the eukaryotic animal host. Additionally, antibiotics target only prokaryotic cells and not eukaryotic organisms. So, this limits the medical treatments that can be used against them.
thus, option D is the correct answer.
Name the types of burns one can get and which structures of the integument are damaged
First degree burns include only the outer layer of skin, otherwise known as the epidermis. Skin in this condition is usually red in appearance, and can be quite painful. An example of a first degree burn injury is a common sunburn. The skin will be dry, and healing usually occurs in 3-5 days. The injured epithelium peels away from the healthy skin during the healing process, and hospitalization is only required if the pain is intolerable or there is a fluid imbalance.
Second degree burns are further divided into two subcategories: partial thickness and full thickness. In partial thickness second degree burns, there may be blisters present and the injury will involve the epidermis and upper layers of the dermis. The wound will be pink or red in color, extremely painful, and may appear wet. This type of burn heals in several weeks without grafting and scarring is usually minimal.
Third degree burns are the most severe type. All layers of the skin are destroyed and the damage extends into subcutaneous tissues. Areas can appear black or white and will be dry or leathery in texture. The wound will not blanch when pressure is applied, and there is no pain involved because the pain receptors have been destroyed along with the rest of the dermis.
How do you know that the plant cells in these two images have different jobs,
or functions?
A. Because all plant cells serve different functions
B. Because they are two different colors
C. Because their DNA are different
D. Because their structures are different
Plant cells have different functions based on their different structures, as diverse structures are adaptations to perform specific jobs.
Explanation:We can determine that the plant cells in the two images have different functions by observing their structures, answer choice D. This principle is known as the structure-function relationship in Biology. Different cells in a plant serve distinct functions, and these functions are often visibly indicated by the cell's structure. For example, a leaf cell that captures sunlight for photosynthesis would look different than a root cell that absorbs water and nutrients from the soil. Their differing structures are adaptations that enable them to effectively perform their particular jobs.

Illegal fishing is thought to account for what percent of fish caught?
A. 10-20
B. 15-40
C. 20-50
D. 50-70
Thank you!
Illegal fishing accounts for a substantial portion of global fish catches, likely falling within the range of 15-40% based on studies and reports on under-reporting and the proportion of illegally caught seafood entering the United States.
Illegal fishing is a significant problem that affects marine ecosystems and economies around the world. According to research, the percentage of fish caught through illegal, unreported, and undocumented (IUU) fishing is substantial, contributing to over-exploitation and depletion of fish stocks. Considering the report by Agnew et al. in 2009 and the data on the under-reporting of global marine fish catches, it is reasonable to deduce that the percentage of fish caught through illegal means could be on the higher end of the provided options.
Additionally, taking into account that 25-30% of wild-caught seafood imported into the United States is illegally caught, as stated by Pramod et al. in 2014, and the significant under-reporting by as much as 50%, the range of illegal catch is likely considerable. Hence, the answer to the question of what percent of fish caught are due to illegal fishing is option B. 15-40%.

how can mutation in a gene lead to a new trait in an organism ?
Answer: D. The mutated gene codes for a protein that causes a new trait
Explanation:
A mutation is a change in the DNA sequence that can occur from multiple causes. For example, by errors during replication or by the action of mutagens such as UV radiation, among others. When a mutation occurs, if not repaired, it can lead to the production of a different protein. This is because genes code for amino acids, which bonded together form proteins. A change in a DNA gene base can lead to code for a different amino acid (or even adding a new one or causing another to be lost). This alteration can lead to the synthesis of another protein involved in the expression of a trait, and giving rise to a different characteristic, which can be beneficial or harmful.

A dam is built that changes water flow nearby. The water flowing through a marsh completely stops. What is the most likely effect of this change?
A. The marsh will become less productive.
B. The marsh will have more oxygen.
C. The marsh will grow more plants.
D. The marsh will have more photosynthesis.
Answer:
A: The marsh will become less productive
Explanation:
Option A is the correct answer because, if the water flow changes to the point where no water is able to enter a certain area, most plant life will die out.
There are a few plants that can survive with very little water, but not enough to sustain a whole ecosystem.
The marsh will not have more oxygen, because underwater plants acquire oxygen through the water surrounding it (oxygen diffuses into the water).
The marsh will not grow more plants, because water is the key factor needed in order for plants to grow, and due to no plants being able to sustain themselves, the rate of photosynthesis will also decrease.

Factor 2: Changes in the amount of atmospheric gases
Which of these statements is correct about the two factors which cause global climate change?
A. Factor 2 is a natural factor, and Factor 1 is influenced only by human factors.
B. Factor 1 is a natural factor, and Factor 2 is influenced only by human factors.
C. Factors 1 and 2 may be influenced by both nature and human factors.
D. Factor 1 is a human-induced factor, and Factor 2 may be influenced by both nature and human factors.
Answer:
c. Factors 1 and 2 may be influenced by both nature and human factors
Explanation:
The sea level rising and the change in the atmospheric gases are both processes that are influenced by the nature, as well as by the human activities. Naturally, the earth has its own cycles, known as Milankovich cycles, through which the Earth warms up, or cools down, resulting in change of the atmospheric gases, and in accordance to that, change in the sea levels depending on the global climate. The humans to have become a big factor in the past few hundred years. The reason for that is that the humans with their activity started to release lot of greenhouse gases into the atmosphere, especially CO2 and methane. That has been changing the composition of the atmosphere, and the temperatures have been rising. The higher the temperatures, the more ice is melting around the poles and on the high mountains, resulting in an increase in the sea levels.

Where do electrons get their energy in photosystem I?
A. From NAD and NADPH
B. From energy in photons
C. From ADP and ATP
D. From glucose in the Calvin cycle
When chlorophyll or carotenoid molecules absorb light and enter a photoexcited state, electrons in Photosystem I acquire energy, hence option b is correct.
What is the light reaction?Through an electron transport chain, the excited chlorophyll electrons are moved from photosystem II's electron acceptors to photosystem I.
Two photosystems—Photosystem II and Photosystem I—are present in photosynthetic eukaryotes and cyanobacteria.
An electron is excited and lost from a PSII reaction center in chlorophyll as a result of light energy (P680).
Therefore, Photosystem I uses light energy to move electrons from ferredoxin on the stromal side of the thylakoid membrane to plastocyanin on the lumenal side of the membrane, hence option b is correct.

Answer: lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air).
Explanation: Hope this helps!!!
The correct answer is C. Atmosphere, lithosphere, biosphere, and hydrosphere.
Explanation
Earth is a planet that belongs to the solar system. The earth is composed of several elements that constantly interact forming a system, that is to say, it is composed of interrelated and dependent parts, so if one of the parts changes, the others are modified, altering the entire system. The main parts of the Earth are its subsystems that are the lithosphere, the atmosphere, and the hydrosphere. These subsystems fulfill specific functions that allow the development of life on Earth. These subsystems are related. Each system has a particular function, the atmosphere contains oxygen and carbon dioxide; the hydrosphere contains all forms of water on earth, and the lithosphere is made up of mineral salts and support for living things. At the same time, these three subsystems allow the existence of the biosphere, that is, the subsystem referring to all forms of life on Earth. So, the correct answer is C. Atmosphere, lithosphere, biosphere, and hydrosphere.

10. Describe rotation and revolution of Earth. What determines an Earth day and year?
11. How do galaxies exist?
12. Compare and contrast the inner and outer planets.
13. What causes the seasons?
Answer:
1. red shift: he displacement of spectral lines toward longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance.
2. blue shift: the displacement of the spectrum to shorter wavelengths in the light coming from distant celestial objects moving toward the observer.
3. The curve changes noticeably about 7.5 billion years ago, when objects in the universe began flying apart as a faster rate. Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart. One explanation for dark energy is that it is a property of space.
4. A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries."
5. Elliptical, Spiral, and Irregular. Two of these three types are further divided and classified into a system that is now known the tuning fork diagram.
A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. Bars are found in between one third and two thirds of all spiral galaxies. Bars generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well.

4.367 light years is how far they are from eachother.
7. Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.[note 1] This is a general physical law derived from empirical observations by what Isaac Newton called inductive reasoning.[1] It is a part of classical mechanics and was formulated in Newton's work Philosophiæ Naturalis Principia Mathematica ("the Principia"), first published on 5 July 1687. When Newton presented Book 1 of the unpublished text in April 1686 to the Royal Society, Robert Hooke made a claim that Newton had obtained the inverse square law from him. In today's language, the law states that every point mass attracts every other point mass by a force acting along the line intersecting the two points. The force is proportional to the product of the two masses, and inversely proportional to the square of the distance between them.[2]
8. Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
9. The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets.
10. Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth's rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.
A day is approximately the period of time during which the Earth completes one rotation around its axis.
An Earth year is 365 days. It's the time that it takes the Earth to orbit the Sun. Each planet takes a different amount of time to orbit the Sun, so the length of each planet's year is different to ours. See if you can match up the planet to the length of year below.
11. One says that galaxies were born when vast clouds of gas and dust collapsed under their own gravitational pull, allowing stars to form. The other, which has gained strength in recent years, says the young universe contained many small "lumps" of matter, which clumped together to form galaxies.
12. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune.
13. The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-cicular path around the sun).

scientific information on climate change
Answer:
Climate change is a broad term which describes the drastic environmental shifts that the earth is experiencing due to both human behaviours and natural processes. Although the earth naturally goes through patterns of environmental change, humans accelerate those changes by putting pressure of the planet. Greenhouse gasses (especially CO2) are expelled by humans through our transportation systems, burning fossil fuels to use as energy, industrial manufacturing, and mass meat farms. These gases cloud the atmosphere, enveloping the earth in gas and creating a “greenhouse effect” that traps the sun’s heat and warms the planet. As the planet unnaturally warms, ice melts and increases the sea levels, ecosystems change to adapt to the new temperatures, animals go extinct under environmental pressures, and natural cycles are interrupted. Additionally, human air, water, and land pollution through trash and chemical byproducts also corrode ecosystems and contribute to climate changes.
