Alleles undergo segregation is
present in the mitosis. The answer is B. The first stage is prophase. The
nucleolus disappears and the two centrosomes begin to form the mitotic spindle.
The spindle xtends between two opposite poles f the cell. Next is the metaphase.
The centromeres of the chromatid pairs align at the center of the miotic
spindle. Then anaphase, the centromeres will split that separates the chromatid
pair. In here, alleles are formed. They are now called chromosomes. The last
phase is the telophase. The chromosomes will then form a thread-like chromatin
and for ache envelope, a nucleoli appears.
Answer:
C. It increases for a while and then decreases.
Explanation:
Answer:
<em>"The limb bones are similar across these species because they share a common ancestor </em>is a right option.
Explanation:
Forelimb (humerus, ulna, and radius) is a homologous structure in all vertebrates. This means that these structures are evolved from the same lineage. Homologous organs could perform different functions but they are structurally similar.
If there is any similarity in different animal's forelimb structure (e.g. horses, goats, and mice), then they are considered to be of same evolutionary origin. Their structures are similar but not function. Evolutionary biology tells us that homologous structures are adapted to different environments as a result of modifications from a common ancestor.
In a nutshell, forelimbs of ancestral vertebrates have evolved into the running forelegs of mice, goats and horses, and the grasping hands of humans.

<h2>Further explanation
</h2>
Biotechnology is a branch of science that studies the use of living things such as bacteria, fungi, viruses, etc. And the products of living things such as enzymes, alcohol in the production process to produce goods and services.
At this time, biotechnology is developing very rapidly, especially in developed countries.
Technological findings from today's biotechnology:
- genetic manipulation
- plant tissue isolation method
- Recombinant DNA
- stem cell breeding
- cloning, etc.

Natural pollution includes smog. Smog is a combination of smoke in an air and fogs.
When you say natural pollution, it is not being caused by human rather caused by a natural resources or organism.
Falling leaves are natural, but its not a pollution.
