Sonbull [250]

Answer:

In mammals, oxygen is carried through the red blood cells called hemoglobin. The reason is that the oxygen is very important for the cell for releasing energy. This energy is used by the cell in different processes.

2) These adaptations are adapted by the organisms in order to perform different functions. In slow twitch skeletal muscles having high number of mitochondria because it requires more energy while fast twitch skeletal muscles contains less amount of mitochondria due to low requirements of energy. These characteristics are adapted according to the performance of the body parts.

Neuroglia do all of the following except:______. a. transmit electrical impulses. b. regulate interstitial fluid composition. c.
Ivenika [448]

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

In a population with two alleles, B and b, the allele frequency of B=0.59. What would be the frequency of the heterozygotes if t
Levart [38]

Answer:

0.483

Explanation:

The given population is in Hardy-Weinberg equilibrium. If the gene has two alleles, the sum total of the frequencies of these two alleles will be one.  

Therefore, the total of the frequency of allele B and frequency of allele b will be 1. f(B) + f(b)=1

If the frequency of allele "B" is 0.59, then the frequency of allele "b" will be=1-0.59= 0.41

The frequency of heterozygous genotype in the population= 2pq

p= frequency of the dominant allele

q= frequency of the recessive allele

So, 2pq= 2 x 0.59 x 0.41 = 0.483
