Answer:

pindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.

serg [7]

Answer:

<u>The correct answer is that our student accumulated lactic acid.</u>

Explanation:

<u>What is acid lactic and where it comes from?</u> It comes from the breakdown of glucose when there is no oxygen present (glycolytic metabolism), that is, in an anaerobic exercise such as running or cycling at high speed, like the case of our student, where there is a high intensity and a very short duration.

<u>What happen then?  </u>When we keep doing exercise with high intensity an exercise, lactic acid will begin to accumulate by not giving the body time to remove it.

<u>How can we avoid lactic acid?</u> With training, there is no more. Based on training, the body deploys adaptive mechanism that causes lactic acid not to accumulate so quickly and if it begins to do so, the muscle supports it more effectively.

An alleles is dominant is heterozygote when it is
Fittoniya [83]

An allele is dominant and heterzygote (Pp) when a dominant allele (P) is crossed with a recessive allele (p).

Explanation:

A dominant allele is the one with a particular dominant character or phenotype which dominates even though there are other alleles found.  

A heterozygous allele results from two different alleles coding for a gene.

A heterozygous dominant allele (Pp) results from the crossing of a dominant allele (P) with a recessive allele due to complete masking of the recessive allele (p).

For example, when dominant brown eyes are crossed with recessive blue eyes, in a heterozygous dominant allele results in brown eyes and masks the recessive blue eyes.
