Answer: B - transports oxygen and carbon dioxide for the respiratory system
The cardiovascular system consists in the heart and all blood vessels. Blood vessels lead the blood from the heart to the rest of the body and then brings it back. It's in the lungs, part of the respiratory system, where the gas exchange is going to happen. What that means is that oxygen is going to enter the blood while the carbon dioxide needs to be eliminated.
(If the option A, said carries hormones FROM the endocrine system, that would be also correct.)

Black eyes are dominant to orange eyes, and green skin is dominant to white skin. Sam, a MendAlien with black eyes and green ski
Anna [14]
<h2>The correct answer is explained below:</h2>

Explanation:

  • According to the given question,
  • For eye color, let the black color be represented by B allele and orange color be represented by b allele. Black is dominant over orange.
  • For skin color, let the green skin be represented by G allele and white skin be represented by g allele. Green is dominant over white.
  • The phenotype of Sam is black eyes and green skin so his genotype can be BBGG or BbGg. It is also said that one of his parents has phenotype orange eyes and white skin. That parent's genotype must be bbgg.
  • Hence, the genotype of Sam must be BbGg.
  • Carole has the phenotype of orange eyes and white skin. Her genotype would bbgg.
  • The gametes produced by Sam are: BG, Bg, bG, bg.
  • The gametes produced by Carole are: bg.
  • Mating them we get,

           BG                    Bg                   bG                       bg

bg      BbGg               Bbgg               bbGg                   bbgg

  (Black/ Green) (Black/ White) (Orange/Green)  (Orange/ White)

  • The genotypes and phenotypes (Eye color/ Skin color) obtained are represented above.
  • The phenotypes (Eye color/ Skin color) obtained are in the following ratio:

(Black/ Green) : (Black/ White) : (Orange/Green) : (Orange/ White) = 1 : 1 : 1 : 1

In the formation of ltp, the entry of ca2 iond inyo yhr neron activates, which are enxymes that contribute to the:_____.
Aliun [14]

In the formation of LTP, the entry of Ca2+ ions into the neuron activates protein kinases, which are the enzymes that contribute to the increased AMPA conductance of the postsynaptic cell.

<h3>What is LTP?</h3>
  • LTP or Long-Term Potentiation is a biological process due to which synaptic connections formed between different neurons grow stronger due to frequent activation.
  • It can be defined as a way by which the responses of brain change along with the experience thus dealing with learning and memory in the hippocampus.
  • It is caused by combining activity of presynaptic and postsynaptic neurons.
  • During synapses, Ca2+ is release as a neurotransmitter from the presynaptic neuron. This Ca+ enters the postsynaptic neuron and activates protein kinases.
  • The protein kinases increase the activity of AMPA receptors which plays an important role in neurotransmission through glutamate.
