  • Paracrine signaling is a type of local signaling in which a cell secretes a signal molecule that affects neighboring cells.
  • The signaling molecules involved in paracrine signaling are known as paracrine factors. These factors are only able to move over a short distance and thus, are able to exert their effect on the nearby cells only.
  • An example of a paracrine factor is the fibroblast growth factor family.

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

<span>What a fascinating question! Just out of college, on my first job, I was called to the delivery room to assist the obstetrician in collecting a blood sample from the not-yet born fetus? scalp. I was nearly immobilized at the sight of the impending birth. Ever since that night, I have gotten goosebumps when witnessing a birth. It is certainly an amazing event, and pondering the entire journey from conception to birth is marvelous! Some of the material I have found is published by religious, political and anti-abotion sites. Neither Google Answers nor I endorse any of these sites. Such web pages were cited here for conception and gestation information, and not because of ideology.</span>
