Answer:

The term extinction's dictionary meaning, is the process of when a species, plant, or any other term for animal family, goes extinct. In more, basic terms, it means when a certain species of animal dies out completely.

This can happen due to several reasons, some being massive natural disasters. Others die out due to an unknown predator entering an ecosystem in which it doesn't belong, therefore disbalancing it.

Examples of extinct animals are Dinosaurs, but their exact reason for going extinct is unkown, there are only theories.

There are also many animals in danger of going extinct, for example Bees.

Hope this information could be of use to you!

1. a) father (Rr), mother (rr)

b) from the attached file(1)

c) the possible genotypes are

  • Rr - 50%
  • rr - 50%

d) but from the information given above the only possible genotype for SpongeGerdy is Rr, because we were told that she was squarepants

e) Rr

f) from the attached file(2)

g) the possible genotypes are

  • RR - 25%
  • Rr - 50%
  • rr - 25%

h) the genotypes for squarepants are RR and Rr

therefore probability is (25 + 50)% = 75% or 3/4

i) the only genotype for roundpants is rr

therefore probability is 25% or 1/4

2. a) wilba - Ee , wilbur -EE

b) from the attached file(3)

c) the possible genotypes are

  • EE - 50%
  • Ee - 50%

d) the genotypes for round eye are EE and Ee

therefore probability is (50 + 50)% = 100% or 1

e) the only genotype for oval eye is ee

therefore probability is 0

3. a) squidward - BB . squidette - bb

b) from the attached file(4)

c) the only possible gene is Bb - 100% or 1

d) the genotypes for a light blue skin are BB and Bb

therefore probability is (0 + 100)% = 100% or 1

e) the only genotype for a light green skin is bb

therefore probability is 0

f) No, they are not. this is because they are heterozygous i.e.( they carry gene for a light green skin)

g) from the attached file(5)

h) the possible genotypes are

  • BB - 25%
  • Bb - 50%
  • bb - 25%

i) the genotypes for a light blue skin are BB and Bb

therefore probability is (25 + 50)% = 75% or 3/4

j) the only genotype for a light green skin is bb

therefore probability is 25% or 1/4

In place of thymine, what does RNA use as a base <br><br> Please help
11111nata11111 [884]
The first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine. This base is also a pyrimidine and is very similar to thymine. Uracil is energetically less expensive to produce than thymine, which may account for its use in RNA.

Which stage of the human immunodeficiency virus (HIV) would a client with a CD4 T cell count of 325 cells/mm3 be classified
kirza4 [7]

Based on the CDC guidelines a person with a CD4+ cell count between 200-400 is regarded as being in <u>the second stage</u> of the HIV infection.

Acquired Immunodeficiency Syndrome

Acquired immunodeficiency syndrome (AIDS) is a condition caused by HIV (human immunodeficiency virus). AIDS is a chronic disorder and can become life-threatening for the infected person. The HIV viruses reproduce inside the host and while doing so they destroy the CD4+ immune cells which reduce the person's ability to fight against other diseases.

CD4+ cell count and AIDS

According to the CDC (U.S. Centers for Disease Control and Prevention), HIV infection is categorized into different stages based on the number of CD4+ cells.

  • Stage 1: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
  • Stage 2: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
  • Stage 3: - The CD4+ cell count falls below 200 and AIDS-related symptoms and conditions are present.
