Answer:

In metaphase 1, chromosomes from the mother and father line up randomly along the middle of the cell.

Explanation:

In diploid (2n) organisms, the homologous chromosomes are the two copies of each chromosome, where one of these homologs is the chromosome from the mother, while the second one is from the father. During metaphase I, the homologous pairs of chromosomes pair together at the middle of the cell. The law of independent assortment, also known as or Mendel's Second Law, states that homologous chromosomes line up in random orientations at the metaphase plate during this period (metaphase I).

The Punnett square is a diagram that is used in the predictions of genotypes. In this scenario, if we have a tall plant (TT) is crossed with a short plant (tt), after using the Punnett square, the genotype that we will get are as follows:.

TT, Tt, Tt, tt

Therefore, the correct option is option D "TT: 1/4; Tt: 2/4;tt: 1/4

Answer: TT: 1/4; Tt: 2/4;tt: 1/4

Answer:

The correct option is E..all of these

Explanation:

This is because all living exhibit functional characteristics which are movement, respiration, nutrition, irritability, growth, excretion, respiration and death. This characteristics are indication that organisms are living things.

Growth: it is the increase in size of organisms. All living organisms grow, they increase in size , from zygote to adulthood.

Metabolism...all living organisms excreate, they absorb nutrients and remove unwanted waste products and undigested good like sweat, urine e.t.c.

Responsiveness....All living organisms respond to stimulus, they respond to external environment or change.

Answer:

In prophase, the nucleolus disappears and chromosomes condense and become visible. In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber.

c. Cells shrivel as water moves out of them.

Explanation:

right on edge 2021

We have that the right behavior of the cell in a situation where excess water enters the cell is

Cells swell as water moves into them.

Option A

Generally Water is Good for the body, But excess of water has its own adverse effect .

Sodium wash away in the blood causes hypo tonic solution in comparison to blood cell.

Therefore, on the count of excess water entering into to the blood cells, the cells tends to rise or swell as water enters into them.

Cells swell as water moves into them.

Explanation:

CFCs and other halogen-source chemicals in the stratosphere were discovered to deplete the ozone layer.

Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere, which is produced by the discharge of chemical compounds from industry and other human activities that contain gaseous chlorine or bromine.

The ozone layer acts as a buffer against the sun's potentially dangerous ultraviolet rays. The destruction of the ozone layer puts humans in direct contact with dangerous ultraviolet rays, which can lead to a variety of health problems including cancer, cataracts, skin illnesses, and a weakened immune system.

Answer:

Asteroids are rocky worlds revolving around the sun that are too small to be called planets. They are also known as planetoids or minor planets. There are millions of asteroids, ranging in size from hundreds of miles to several feet across.

Answer:

See the answer below

Explanation:

1.      Tt   x   Tt

   TT  Tt   Tt   tt

Assuming that T is dominant over t:

Genotype ratio = 1TT:2Tt:1tt

Phenotype ratio = 3:1

2.     Rr   x   Rr

    RR   Rr   Rr   rr

Assuming that R is dominant over r:

Genotype ratio = 1RR:2Rr:1rr

Phenotype ratio = 3:1

3.  Assuming that green (G) is dominant over the other color (g). Heterozygous green would be Gg

        Gg   x   Gg

     GG   Gg   Gg   gg

Genotype ratio = 1GG:2Gg:1gg

Phenotype ratio = 3:1 (green ratio the other color)

4. Assuming that green (G) is dominant over the other color (g) as above:

  homzygous green plant = GG; heterozygous green plant - Gg

      GG   x   Gg

   GG   Gg   GG   Gg

Genotype ratio = 1GG:1Gg

Phenotype ratio = 100% green

5. Assuming that tall (T) is dominant over short (t)

Homzygous tall plant = TT

short plant = tt

         TT   x   tt

       Tt   Tt   Tt   Tt

Genotype ratio = 100% Tt

Phenotype ratio = 100% tall

Answer:

The second line of defense.

Explanation:

In our bodies the second line of defense includes active immunity. It contains non-specific immune responses, but yet still contains specific responses for certain things such as inflammatory and fevers.

Third line of defense includes active immunity. The correct option is C.

The first line of defense consists of chemical and physical barriers that are constantly ready to defend the body against infection.

Your skin, tears, sputum, cilia, stomach acid, urine flow, 'friendly' bacteria, and white blood cells called neutrophils are examples of these.

The second line of defense assists administration in effectively managing risk and controls.

Organization develops multiple risk management and compliance functions to assist in the development and/or monitoring of first-line controls.

Immune cells that specifically target antigens are the third line of defense. B-cells and T-cells, all white blood cells, are immune cells that play a role in the third defense line.

Antibodies are produced by B-cells. T-cells aid in the identification of pathogenic cells and the destruction of those cells.

Thus, the correct option is C.
