Which correctly describes crossing over?

Biology

ollegr [7]1 year ago
4 0

The correct option is A ie the process whereby non-sister chromatids exchange genetic material

  • Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.
  • When genetic material is switched between two chromosomes, this process is known as crossing over.
  • It is in charge of causing genetic variation among members of a species.
  • Only the reproductive cells known as gametes undergo this process.
  • The steps involved in crossing over are as follows:

1) Synapsis.

2) Chromosome duplication

3) Crossing over.

4) Terminalizataion.

Answer:

Circulatory system remove waste from the cell and provide clean blood to the cell.

Explanation:

During cellular respiration, lungs inhale oxygen which stored in the alveoli. The red blood cells contains hemoglobin that carries deoxygenated blood containing carbondioxide from the cell in the veins to the heart and unload this carbondioxide gas in the alveoli of the lungs and load oxygenated blood having oxygen from the alveoli through capillaries in order to provide oxygen to the cells that is necessary for the survival of humans. Platelets are the type of cells that helps in blood clotting whereas white blood cells provides immunity against pathogens.

Shalnov [3]

Answer:

1/4

Explanation:

Cystic fibrosis is a recessive disorder and therefore, is expressed only in homozygous recessive genotype. Let's assume that the allele "c" is responsible for the disease in the homozygous state. Since the couple already has a child with cystic fibrosis (cc), they both are heterozygous carriers for the disease.

The genotype of male and female each is "Cc". A cross between Cc x Cc gives progeny in the following phenotype ratio=1/4 diseased: 1/2 normal carriers: 1/4 normal. Therefore, the probability of getting a diseased child for them is 1/4.

Which is more highly demand, FORENSIC or MARINE BIOLOGIST ? Explain​
Umnica [9.8K]

Answer:

A marine biologist is more in demand. A marine biologist is a scientist who studies plants and animals that live in the ocean. A marine biologist seeks to understand ecosystems, biology and behaviors while analyzing how different marine species interact with each other. Besides studying how ocean life affects itself, marine biologists may also examine the impact that human interaction has on marine biology. Explanation:

What rule or reasoning did you use to decide how to label the cut end of the short piece of magnet?
andrew-mc [135]

Answer:

<em>You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will <u>become the new north or south poles of the smaller pieces.</u></em>

Aristo was riding in a car and noticed a pond that was covered in algal blooms. Which of these other features in the landscape c
netineya [11]

The answer is cow pasture.

When the dead cow pasture decomposes, it releases phosphates into the environment. In addition, the cows that feed on the pasture release manure with phosphates content. When the phosphates reach the pond, they spur up bacteria and algal growth in the pond causing an algal bloom. This results in taking up of dissolved oxygen (for cellular respiration) until the waters become anoxic.
