Answer:

Question 1 - c. vv

Question 2 - b. Any of the non-sex chromosomes

Question 3 - b. Eukaryotic

Explanation:

Question 1

As explained, the gene for normal wings (V) is a dominant gene while the gene for the vestigial wings (v) is recessive. Dominant genes overpower any recessive genes.

VV - Two dominant genes will produce the dominant trait

Vv - The dominant gene (V) overpowers the recessive gene (v) and produced the dominant trait.

This means that the only way to have a fly with vestigial wings is if the fly has 2 recessive genes. This means that our answer is c. vv

Question 2

An autosome is defined as any of the non-sex chromosomes.

Question 3

Linear chromosomes are a type of chromosome most often found in eukaryotic cells. On the other hand, prokaryotic cells usually have circular chromosomes. This means that our answer is b. eukaryotic

What is the function of a pollen tube?
Firlakuza [10]

Answer:

The function of the pollen tube is to lead sperm cells into the ovary.

Explanation:

In angiosperms, the pollen tube is a structure formed when the pollen grain comes into contact with the stigma and germinates, producing a tubal extension that is related to the embryonic sac where the female gametophyte is found.

The function of the pollen tube is to conduct the male gametophyte —which is found in the pollen— to the embryonic sac, in order to come into contact with the oosphere and produce fertilization.

The other options are not correct because the pollen tube:

  • <em>Do </em><u><em>not create more pollen</em></u><em>. </em>
  • <em>Do </em><u><em>not create more male spermatophytes</em></u><em>. </em>
  • <u><em>Does not lead the eggs to the male spermatophytes</em></u><em>.</em>
