What do vestigial structures teach us?

Biology
1 answer:
o-na [289]2 years ago
3 0

Answer: They teach us about the evidence of evolution

Explanation: According to https://flexbooks.ck12.org, "Structures that have lost their use through evolution are called <u>vestigial structures</u>. They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure, or using it for a different purpose."

A botanist has acquired a group of sweet pea plants. All of the plants have yellow pea pods (the recessive trait), except for on
Advocard [28]

Answer:

In order to find out the genotype we do a testcross of green pea pods with yellow pea pods.

Explanation:

1. If the F1 generation consist of green pea pods only then the genotype of the green pea pod is 'GG' (i.e the dominant alleles).  

<h2>                           TEST CROSS </h2>

                    Green pea pods        X           Yellow pea pods

                                    GG              X              gg

       <u>Gametes: </u>

                                     G               X                g

      <u> F1 Generation: </u>

<h2>                                 Gg </h2>

2. However if the F1 generation consist of 50% green pea pods and 50% yellow pea pods then the genotype of green pea pods is 'Gg' (both the dominant and recessive alleles).

                   Green pea pods        X           Yellow pea pods

                               Gg                  X               gg

       <u>Gametes: </u>

                           G      g      X        g

       <u>F1 Generation:</u>

<h2>                              Gg, gg </h2>

We can relate this to Mendel's Law of segregation and meiosis as

  • Both the alleles segregate into seperate gametes (i.e they are sorted independent of one another).
  • This segregation is similar to the first division of meiosis in which homologous chromosomes of gene are segregated in daughter nuclei

Why do solvent particles flow into the cell when the initial volume is below 50%?
vredina [299]

Answer: Differences in osmotic concentrations

Explanation: With solvent particles flowing into the cell, it means the concentration outside of the cell is higher and with initial volume less than 50%, then that within the cell is lower. This results in an osmotic gradient, allowing particles in areas of higher concentration (outside the cell) to flow into the cell, an area of lower concentration.
