What gametes are produced by the following organisms:_______.

Biology
1 answer:
vova2212 [387]2 years ago
3 0

Answer:

The correct answer would be -

1- YR, Yr, yR and yr.

2. Yr, yR

3. YR, yr

4. YR, Yr, yR & yr

Explanation:

A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.

The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.

1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.

2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.

3).  if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.

4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.

During strenuous exercise, anaerobic conditions can result if the cardiovascular system cannot supply oxygen fast enough to meet
GaryK [48]

Answer:

Glucose utilization would increase a lot.

Explanation:

Aerobic condition indicates the presence of large amount of oxygen in the body. Anaerobic condition means that the oxygen is limited or deficient in the body.

The muscle cells shows anaerobic condition during exercise and produces lactic acid. Since, the ATP demand is same in both the  aerobic and anaerobic conditions. This increases the demand of glucose in the body. Glucose utilization is increased to provide proper energy to the individual.

Thus, the correct answer is option (a).

Which of the following is not an effect of complement activation? Select one: Interference with viral replication Increased phag
Nostrana [21]

Answer:

The correct answer is "Interference with viral replication".

Explanation:

The complement system is an essential part of the immune system that involves the activation of a series of proteins that act as a cascade and result in the development of inflammatory responses that help to fight infections. There are multiple effects of complement activation, however interference with viral replication is not one of them. The molecules that are able to interfere with viral replication are called interferons, and they synthesis and activation are not related with complement activation.

How is it possible that over 20 million living organisms on the planet are made up of only 5 types of nucleotide based arranged
almond37 [142]

Answer/Explanation:

The DNA in all living organisms is made up of 4 bases, adenine, thymine, guanine, cytosine. The RNA replaces thymine with uracil, making 5 types of nucleotide. The number of nucleotide pairs in a genome can range from half a million up to 100,000 million - meaning there are an exponential number of combinations of these 4 bases.

Imagine an organism exists that has only 2 nucleotides (<u><em>this is over 200,000x smaller than even the smallest bacterial genome</em></u>). If we allow any nucleotide at each of the 2 positions, then we have 4x4 (4²) or 16 possible combinations of sequences. For a nucleotide length of 4, the total number of possible combinations are 4⁴ or 256.

Since we are dealing with many millions of nucleotides, there are essentially infinite combinations of nucleotides, giving rise to the variation that produces over 20 million organisms on the planet.

Explain the water cycle in a paragraph
stepan [7]

Answer:

Water cycle is also called hydrological cycle. In this cycle water moved continuously above the surface of the earth for the continuity of life. Water is evaporated from the sea and ocean in the process of evaporation. This water goes to the atmosphere and form clouds. These clouds moves to hilly areas and comes to the ground in the form of rainfall and snowfall etc. Some water is stored on the mountains in the form of snow and the remaining downward through streams.
