During Meiosis, the alleles on each gene will separate individually into the gametes. This means that no matter what alleles wer
Katyanochek1 [597]
<h3><u>Answer;</u></h3>

Independent Segregation

<h3><u>Explanation</u>;</h3>
  • <em><u>According to Mendel's law of segregation, a sperm or egg carries only one allele for each inherited trait because allele pairs separate from each other during the production of gametes. Independent segregation occurs as a result of separation of homologous chromosomes during anaphase I of meiosis I.</u></em>
  • The law of independent assortment on the other hand, states that each pair of alleles separate independently of the other pairs of alleles during gamete formation. Independent assortment results from the orientation of homologous chromosomes in metaphase I of meiosis I.

Identify the phase of mitosis for each plant cell diagram shown below.
madreJ [45]

Answer:

1. Metaphase

2. Prophase

3. Telophase

4, 5, 6, 8. Interphase

7. Anaphase

Explanation:

Mitosis is a cell division involving the formation of two genetically daughter cells. The process of mitosis involves stages including: interphase, prophase, metaphase, anaphase and telophase.

Interphase is the resting stage of the cell. It is th stage where the cell prepares for the division. Numbers 4, 5, 6, and 8 in the image are stages of interphase.

Prophase is the stage where the chromosomes become visible and arrange in pairs. Number 2 in the image depicts a plant cell in prophase stage.

Metaphase is the stage where the chromosomes align at the equator/middle of the cell. This alignment orients the chromosomes for separation. Image 1 depicts this metaphase stage.

Anaphase stage is the stage where the chromosomes separate into opposite poles of the cell. Image 7 depicts the anaphase stage of this plant cell.

In the Telophase stage, the cell plate forms to divide the plant cell into two. This is shown in image 3.

True of False: Hemoglobin releases the same amount of oxygen to all the tissues regardless of variations in their metabolic rate
Murljashka [212]

Answer: False

Explanation:

Hemoglobin can be defined as red protein that transports oxygen to various parts of the body according to its need.

It does not transports the same amount of oxygen to all the tissues. Some tissues of the body might require more more oxygen and some cells might require less amount of oxygen.

It depends on the state of activity. It transports more oxygen to the tissue that require it the most.

Example: The skeletal muscles of the body require more oxygen and it can be more than 80% .

Hence, the given statement is false and hemoglobin does not releases the same amount of oxygen to each and every tissue of the body.
