Answer:
artificial selection/selective breeding
Explanation:
The illustration is an example of <u>artificial selection.</u>
<em>By definition, </em><em>artificial selection</em><em> is the deliberate perpetuation of some traits in living organisms simply because the traits are desirable. The organisms are selected because of the traits and allowed to breed either naturally or otherwise in order to ensure that these traits appear or are even consolidated in the offspring of the breeding. </em>
The offspring from selective breeding are expected to combine the desirable traits of the two parents and thus, appear better than each of the parents.
Answer:
1. 20 chromosomes
2. 10 chromosomes
3. 10 chromosomes
Explanation:
1. The process of mitosis results in the two daughter cells from the same parental cell with exactly the same genetic material. Thus the two cells contain the same number of chromosomes as the parent cell. Therefore if a cell with 20 chromosomes undergoes mitosis will result in the 20 chromosomes.
2. During meiosis I two daughter cells are formed with different ploidy levels as the number of the chromosome reduces to half. Therefore the cell with 20 chromosomes results in two cells with 10 chromosomes.
3. During meiosis II, the two daughter cells formed from meiosis I result in the formation of two more daughter cells with an exact number of chromosome number that is 10 chromosomes.
Answer:
the shaft and the bone marrow
Explanation:
A hard outer layer called cortical (compact) bone, which is strong, dense and tough. 2. A spongy inner layer called trabecular (cancellous) bone. This network of trabeculae is lighter and less dense than compact bone.

The answer is <span>b. Swamps are deeper and have a larger proportion of surface water than marshes, and bogs have acidic groundwater.
Bogs, marshes, and swamps are types of wetlands. Swamps and marshes are mineral soil wetlands. Swamps are deeper and with a larger proportion of surface water than marshes. Usually, swamps develop from marshes that fill in. Bogs are organic soil wetlands. They are acid areas with acidic groundwater.</span>
C. Arachnida.
hope it's correct.
