how do mutations lead to genetic diversity?
The mutation Mutations are changes to an organism's DNA and are an important driver of diversity in populations. This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

Compare the number of mitochondria in the different types of cells.
Answer:
High amounts of mitochondria are found in skeletal muscle cells, as well as liver cells. On the other hand, skin cells have a small amount of mitochondria.

What phase of mitosis is shown in the picture above?
A. Metaphase
B. Anaphase
C. Telephase
D. Prophase
The phase of mitosis which is shown in the picture is Metaphase. Thus, the correct option is A.
What is Mitosis?Mitosis may be defined as the type of cell division in which two daughter cells are formed from a parental cell with the exact number of chromosomes.
In metaphase, the chromosome usually lines up in one plane and forms an equatorial plate in which they are attached to the spindle fiber through their centromere.
Therefore, the phase of mitosis which is shown in the picture is Metaphase. Thus, the correct option is A.

A. Meiosis forms two cells all with the same genetic material
B. Meiosis forms two cells all with different genetic material
C. Meiosis forms four cells all with the same genetic material
D. Meiosis forms four cells all with different genetic material
Answer:
D. Meiosis forms four cells all with different genetic material
Explanation:
They are haploid cells and each cell only had one set of chromosomes. Meiosis results in variation.

Answer:
In nature, populations are usually evolving. The grass in an open meadow, the wolves in a forest, and even the bacteria in a person's body are all natural populations. And all of these populations are likely to be evolving for at least some of their genes. Evolution is happening right here, right now!
To be clear, that doesn't mean these populations are marching towards some final state of perfection. All evolution means is that a population is changing in its genetic makeup over generations. And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection. Other times, it comes from migration of new organisms into the population, or from random events—the evolutionary "luck of the draw."

Which statement is not an example of how the use of resources has changed?
A. More products are made from recycled materials.
B. Cars still largely rely on oil.
C. Car companies have developed hybrid cars.
D. More wind farms are present in the United States.
Answer:
B. Cars still largely rely on oil.
Explanation:
Nowadays, most countries still use transportation systems that burn fossil fuels. An example of this may be private cars that consume gasoline, which derives from fossil fuels (oil). The use of fossil fuel transportation systems increases the emission of carbon dioxide (CO2), a major greenhouse gas involved in global warming. In the near future, it is expected that fossil fuel-based vehicles can be replaced by electric cars that use energy obtained from renewable sources (e.g., solar energy, wind energy, etc).

B is not correct. I know cause I took the test here are the correct answers!

And object is 20 cm from the lens. The image from 6.66667 cm from the length. What is the focal length of the lens? Use the thin lens equation
Answer:
5
Explanation:
The object distance Is 20 I'm
The image distance is 6.666
Therefore the focal length can be calculated as follows
1/f = 1/20 + 1/6.66
= 6.66+20/133.2
= 26.66/133.2
1/f= 26.66/133.2
f = 133.2/26.66
= 4.99
= 5
Hence the focal length is 5

Why is it difficult to fossilize large animals?
Answer:
The onerous elements of organisms, like bones, shells, and teeth have a far better likelihood of changing into fossils than do softer elements. One reason for this can be that scavengers typically don't eat these elements. onerous elements conjointly decay additional slowly than soft elements, giving longer for them to be buried.

What would happen if the rate of evaporation reduces
Answer:
When temperature and wind speed are constant, but humidity increases, the rate of evaporation will decrease. When wind speed and humidity stay constant, and temperature increases, then the rate of evaporation will increase because warmer air can hold more water vapor than colder air.
Answer:
if the rate of evaporation reduces water cylcle will stops and amount of water present in the world will be increase.humifity will be more.

How can you explain the difference in number of mitochondria in these types of cells?
Answer:
Organs which need alot of energy to function properly have a greater number of mitochondria
Explanation:
Mitochondria are sites for respiratory enzymes which yield energy for the cells thus skeletal muscles which need alot of energy have more mitochondria than liver and liver due to doing more activities than skin has more mitochondria than the skin.
Answer:
Skeletal muscle cells have a very high amount of mitochondria as well as liver cells because they need high amounts of energy to carry out their functions, whereas skin cells don't need high amounts of energy to function.
