Answer:
Explanation:
<em>Let the ability to break down the red color in beets be represented by the allele </em><em>B</em><em>. The inability would be represented by the allele </em><em>b</em><em>.</em>
A nonsecretor's genotype would be BB or Bb while a secretor's genotype would be bb.
A nonsecretor woman with a secretor father would be a carrier with genotype Bb. A nonsecretor man who in a previous marriage had a secretor daughter would also be a carrier with genotype Bb. If the two marries:
<em>Bb x Bb</em>
<em> BB 2Bb bb</em>
1.
(a) probability of their first child will be a secretor girl = probability of having a girl and being a secretor.
Probability of having a girl = 1/2
Probability of being a secretor = 1/4
<em>probability of their first child will be a secretor girl</em> = 1/2 x 1/4 = 1/8
(b) Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor.
Probability of having a girl = 1/2
Probability of being a nonsecretor = 3/4
<em>Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor</em> = 1/2 x 3/4 = 3/8
2. <em>Probability that their first two children will be nonsecretors of either sex = probability of their first being a nonsecretor and of either sex and probability of their second being a nonsecretor and of either sex.</em>
= 3/4 x 3/4 = 9/16
So the organisms could be classified in the same animal families
Answer:
Option A, transmit electrical impulses
Explanation:
Neuroglia also known as glial cells which act as supporting cells for the nervous system and its functioning. These cells surrounds the neurons and produce insulation between them as they produce myelin sheath that coats the axon. There are six types of neuroglia cells and they all work to provide essential nutrients to the neuron cell and also maintain the homeostasis (under which it also regulate the interstitial fluid composition and repair tissue framework)
Hence option A is correct
Your answer should be tissues.
Answer:
Nuclear energy can be used and controlled and it is more efficient than other forms. I would say B.
