Mitotic division in onion root cells:

  1. Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
  2. Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
  3. Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
  4. Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.

Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.

What is the function of a conversion factor?
Naily [24]

Answer:

A conversion factor is a numeric expression that enables feet to be changed to chains as an equal exchange. A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used.

<h2>Hypomorphic allele</h2>

Explanation:

  • Hypomorphic Alleles : A change that reduces, however, doesn't dispense with a gene's usefulness is hypomorphic. A progressively extreme condition, amorphic transformation, dispenses with the gene's capacity.
  • The great analyses characterizing hypomorphic alleles go back to the 1930s. Herman Miller, who won a Nobel Prize for finding that radioactivity causes changes, considered the eyeshade of organic product flies. These flies typically have red eyes, yet freak assortments can have white or apricot-hued eyes. The allele liable for various natural product fly-eye hues is known as the white allele, with the contraction "w."

In a fish species, the number of eggs that hatch and survive for one year varies depending on the number of eggs that were produ
Alenkinab [10]

Answer:

C. The chance of survival decreases when there is intraspecific competition for resources among surviving yearlings

Explanation:

The survival rate of the offspring of the fish species will decrease as a result of the huge number of eggs produced giving rise to overpopulation. Pressure will be on the limited available resources. As a result of this, Intraspecific competition would occur as members of the same fish species would compete for the limited resources.  

Interference and exploitation competition are two types of Intraspecific competition that can reduce the population size of the fish species.

For Interference competition, the dominant and stronger members would secure adequate supply of the limited resources to  detriment of the weaker and less dominant ones. This leads to the death of those members that are weak to compete successfully, thereby leading to a reduction in population size.

In exploitation competition, it involves all individual members of the fish species sharing the limited resources equally, while none of them gets an adequate amount. With time, a great size of the population decrease would be noticed when compared to that of Interference competition.
