Which of the steps in this sequence of events is an example of mitosis at work?
taurus [48]
<span>The bruise slowly disappears as the arm heals.

</span>
<span>The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size.

In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of the allele a is 0. 3. What i
zavuch27 [327]

Here, given-

homozygous alleles 'a' have a frequency of 0.3.

Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.

The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.

Calculation-

p + q = 1\\0.3 + q= 1\\q= 1- 0.3\\\\q= 0.7

Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-

p^{2} + 2pq + q^{2} =1

p^{2} = dominant homozygous frequency\\2pq= heterozygous frequency\\q^{2} = recessive homozygous frequency\\

Thus, the individuals homozygous for the allele can be calculated by q^{2} = (0.7)^{2} \\= 0.49

A researcher incubates a cell with radiolabeled amino acids. These amino acids are incorporated into the proteins as they are sy
AURORKA [14]

Answer:

The incorporation of radiolabeled amino acids during protein synthesis occurs when the data shows the organelles involved with protein synthesis, packaging and transport, that is, radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the Golgi, and then the secretory vesicles (option C).

Explanation:

Protein synthesis in the cell occurs when RNA -which contains the sequence of triplets or codons that make up the genetic code- is coupled to ribosomes.

Each codon or triplet, consisting of three nucleotides, will give instructions for specific amino acids to be incorporated into the polypeptide chain that is being synthesized in the rough endoplasmic reticulum.

The Golgi apparatus is responsible for packaging or packaging the newly synthesized proteins in secretory vesicles for transport.

<em>In consecuense, </em><u><em>radioactivity levels would increase in the organelles involved in protein synthesis, packaging and transport, the rough endoplasmic reticulum, Golgi apparatus and secretory vesicles</em></u><em>, respectively.</em>

3. Label the three planes in the following image next to the three corresponding letters below the image.
Gelneren [198K]

Answer:

The correct labels of the three planes are -

a. axial or transverse plane.

b. sagittal plane

c.. coronal plane

Explanation:

The human body can be divided into three planes on the basis of anatomy - the sagittal plane, the coronal plane, and the transverse plane

A sagittal plane is a longitudinal plane that divides the human body in the left and right parts.

A coronal plane is an anatomical plane that divides the body vertically into the back and front, ventral or dorsal (to be more specific).

An Axial or transverse plane, it is the plane that divides in the upper part of the body and lower part of the body.

Thus, the correct answer is -

a. axial or transverse plane.

b. sagittal plane

c. coronal plane
