Answer:
16 chromosomes
Explanation:
A diploid cell is a cell with two complete set of chromosomes (2n). The somatic or body cell is a cell that has no part to play in reproduction. Hence it is simply meant for other functions like growth, repair etc. other than reproduction.
All cells undergo mitosis, while only reproductive cells undergo meiosis. Hence, a cell with 32 body chromosomes will undergo meiotic division to produce gametes.
N.B: Meiosis is one of the two types of cell division, other being mitosis, that produces four daughter cells (gametes) with each having half the number of chromosomes as the parent cell. It is also called reduction division.
In this case, a diploid (2n) cell with 32 chromosomes will undergo meiosis to produce gametes with 16 chromosomes each (reduced by half). This is to ensure that during gamete fusion or fertilization, each resultant individual/zygote received the correct number of chromosomes i.e. 16 (from male) + 16 (from female) = 32 chromosomes in total.
Answer:
A) Reticular activating system
Explanation:
The reticular activating system is a complex network of neuron present in the brainstem of the brain.
The reticular system is involved in many functions of the brain like the flight or fight response, the sleep and awake awareness and the elimination of the unwanted and unimportant stimuli of the person.
In the given question, since the person, while studying unconsciously avoids the rustling of paper and the pressure of the clothes which is performed by the reticular system in the brain.
Thus, Option-A is correct.
Answer:
Enzima conversora de angiotensina
Explicação: A redução da pressão arterial do corpo é devido à homeostase. homeostase refere-se à capacidade do corpo de regular o estado interno se houver mudança no ambiente externo. Nosso corpo tem a capacidade de manter o ambiente interno do corpo estável devido à mudança que ocorre no ambiente externo do corpo. Baixar a pressão arterial ao normal é um exemplo de homeostase. A enzima de conversão da angiotensina é responsável por baixar a pressão arterial ao normal.
A. It produces few offspring/s because if it was B. The identical offsprings which means Twins the Questions would have been with twins. Asexual Reproduction is when One produces a child/animal/plant consisting Organisms.
<em>50% of the sons have the disorder. </em>
<em />
When this couple has children, one half of their sons will have the disorder. When a male has an X-linked, recessive disorder, his genome will be YXₙ, where Xₙ represents his affected X-chromosome. Since boys can only have one X-chromosome, they cannot be carriers. Having one affected X-chromosome makes them have the condition. His wife, who is not a carrier and does not have the condition will have the genome XX. As you can see in the punnet square, this cross will lead to two sons, one of which has the color-blindness gene. So, 50% of the sons will have the disorder.
