Answer:
The correct option is : b. centrosome
Explanation:
Centrosome is a cell organelle, which acts as the microbule organizing center and also regulates the cell cycle progression in an eukaryotic cell.
During the prophase stage of the cell cycle, the centrosomes are associated with the membrane of the nucleus. The nuclear membrane ruptures during the mitosis and the interaction of the centrosome nucleated microtubules with the chromosomes leads to the formation of the mitotic spindle.
<u>Therefore, mitotic spindles arise from the centrosome.</u>
I don't see the statements. Can you please comment on this telling me them so I can answer your question properly? Thank you!!
An organism that exhibits a head with sensory equipment and a brain probably also have receptors, which capture the stimuli of the environment and transform them into a nervous impulse, and organs of the senses that are the communication channels we have with the environment and thanks to them we understand and interpret the environment, they are: vision, hearing, smell, taste, and touch.
Yes, it is possible.
However, this is only possible if BOTH of the parents have a recessive allele for blue eyes, i.e. they're heterozygous.
Let only one gene is controllable of the eye color. Let the brown eye dominant allele be R and blue recessive be r. So, only if both parents have the genotypes of Rr, they can produce a baby with rr due to random selections at meiosis, and the baby phenotype would be blue eyed.
If they're both RR or at least one is, the chance of having a blue-eyed baby is impossible.
