describe the formation of platelets from pluripotent stem cells, including the influence of hormones.
Ymorist [56]

The formation of platelets from pluripotent stem cells, including the influence of hormones.

Pluripotent stem cells form are the cells that can form all the cells of the body including ectoderm, mesoderm and endoderm but not the extra-embryonic structures like placenta.

Platelets are formed by a precursor cell called megakaryocyte which are present in the bone marrow. It is actually present in the kidney in the form of myeloid stem cells which forms the megakaryoblast which transforms into megakaryocytes.

Thousands of plateletes are formed by the megakarocytes. Thrombopoietin is the hormone which regulates plateletes formation.

vlada-n [284]

Answer:

1)

  • frequencies of light-colored mice  ≅ 0.74
  • frequencies of dark-colored mice ≅ 0.26

2)

  • frequencies of light-colored mice ≅ 0.13
  • frequencies of dark-colored mice ≅ 0.87

3)

  • q² = 0.74
  • p² = 0.02
  • 2pq = 0.24      

4)

  • q² = 0.13
  • p² = 0.4
  • 2pq = 0.46

5)

The dark-colored fur seems to have the greatest overall selective advantage

6)

Dark lava, that changed the color of the substrate, from light to dark.

7)

Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.

8)

To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.

The proteins are biomolecules which can act as hormones and enzyme catalysts which can help in catalyzing the chemical reactions. They help in the transport of the molecules and cell membrane trafficking. The proteins are antibodies which can bind to antigens and the foreign materials. The genetic information is carried by the genes in the DNA, and not proteins.
Thus, the correct answer is option 'They contain genetic information.
