Answer:
Genetic Diversity refers to the range of different inherited traits within a species. In a species with high genetic diversity, there would be many individuals with a wide variety of different traits. Genetic diversity is critical for a population to adapt to changing environments.
Answer:
Genetic Diversity Definition Genetic diversity is defined as the sum of different alleles within a species or population. Both the huge number of distinct species and the variety within a species are referred to as genetic diversity. Genetic diversity refers to the diversity of genes within a species. Therefore, it represents a variety of genes within a species. The basic unit of life on earth is the gene.

Constructed Response: Identify & describe 2 ways removing trees from a forest can affect the organisms who live there. Using the vocabulary words: Organisms, populations, communities, ecosystems, abiotic factors, and biotic factors.
Answer:
are scale tree cutting can lead to deforestation, a transformation of an area from forest to terrain with little vegetation. A biosphere is the term used to describe the combination of every ecosystem on the planet. Our biosphere is Earth. The biosphere includes all living beings and their relationships. Changing temperatures can alter which organisms can survive in an ecosystem. Plants create oxygen and absorb greenhouse gases. The destruction of trees may, therefore, encourage global warming .Biotic factors pertain to living organisms and their relationships. Abiotic factors are the non-living components of the ecosystem, including sunlight, water, temperature, wind, and nutrients. Ecologists use biotic and abiotic factors to predict population changes and ecological events. A biome is the term used to describe organisms that occupy a certain area. Biomes are determined by the primary vegetation type, the climate of the area, and the geographic location. The plants and animals in a biome share common traits that are specific to the individual biome those plants and animals inhabit.

In which situation would a mutation be passed from parent to offspring?
When the mutation is in a sperm cell.
When the mutation is in a skin cell.
When the mutation is in a muscle cell.
When the mutation is in a bone cell.
When the mutation is in a sperm cell
Mutation in gametes or in the gametes forming cells are passed to the offspring as the chromosomes from the gametes that are mutated are used to form the offspring . Gametes are sperm form male and egg from female
other cell having the mutated chromosomes will only reside in the cell it self may divide to form multiple cell but that will not transfer the chromosomes to the next generation .

Explanation:
Identify two ways in which scientists know the physical characteristics of organisms change over time.
The two ways in which scientists know the physical characteristics of organisms change over time are by examining the fossil record and comparative anatomy of these organisms.
What is comparative anatomy?One way where scientists know the physical characteristics of organisms has changed with time is through examining the fossil record. Fossils are the remains of organisms preserved in sedimentary rock over time.
The studying of fossils helps scientists to compare the physical characteristics of the organisms with modern organisms by observing the differences between them and the changes that occurred over time.
Another way is to go through comparative anatomy which involves comparing the physical structures of different organisms and identifying the similarities or differences in their anatomy that helps scientists to identify the changes and how these changes have affected these organisms.
Therefore, by examining the fossil record and comparative anatomy of these organisms help scientists to know the physical characteristics of organisms that have changed over time.

Consider the following data about populations of red squirrels, gray squirrels, and foxes. Two students looked at the data about how the red squirrel populations changed over time. Each made a claim about a cause-and-effect relationship. Student A: I think an increase of the fox population caused the red squirrel population to decline. Student B: I think an increase of the gray squirrel population caused the red squirrel population to decline. Which student do you agree with most? _____ Describe the evidence that supports this claim.
Answer:
Student A
Explanation:
I agree with student a because if u look around the 10 year mark you see the fox population pick up a lot and see the squirrel population decline.

Above a horizontal line running through the center of a double concave lens, a large car to the left of a double concave lens and a small car to the right. On the line at the front of the large car a point labeled Focal point. On the line to the right of the small car a point labeled Focal point. A dotted line 2 goes from the left focal point up and right through the center top of the lens and then solid to a label 2. A straight line goes from the top of the car straight to the center of the lens. A solid line goes from through the lens, becomes dotted, and goes to the right Focal point. A solid line goes down and right from the top of the car through the center of the lens to a label 1 below the right Focal point. A straight dotted line starts at the intersection of 1 and 2, becomes solid in the center of the lens, and goes to a label 3.
Which best explains how to correct Akio’s mistake?
Change the lens so it appears convex instead of concave.
Move the small car so it appears on the left side of the lens.
Make the small car much larger than the other car.

Answer:
Dear people in Westfield,
your pipes contain rust because of a chemical reaction on the iron you use.The problem could be fixed by using strong plastic pipes as that takes a long time to degrade.The rust is produced when water and air mix with the iron.it takes time for the pipe to rust but that is the problem
as I said before,try using plastic pipes that are resistant to pressure.you could get them at home Depot or other pipe production company's.

Are all human cells capable of mitosis and cell division? How does this affect the body's ability to repair itself? Support your answer with specific examples. at least 3 sentences please i am desperate i will give brainliest
(This is not about reproduction)
Mitosis and cell division are possible in all human cells. Mitosis has several functions in the organism, including growth, cell repair, and some forms of reproduction. Humans make two types of cells. Body Cells and Reproductive Cells are two types of cells. Mitosis employs diploid cells to attack viruses and bacteria while also repairing cells.
Answer:
It repairs itself by using red blood cells to kill all the bacteria.

Explanation:
What are coronary arteries? What are their function? How are they involved in heart disease?
Answer:
Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart. Since coronary arteries deliver blood to the heart muscle, any coronary artery disorder or disease can have serious implications by reducing the flow of oxygen and nutrients to the heart muscle. This can lead to a heart attack and possibly death.
