Answers

Answer 1

NASA help to distinguish genetic factors from environmental ones  by

analyzing changes experienced in one twin on Earth and the other in space.

NASA planned to study how environmental conditions affects the health

conditions of humans. They decided to use twin brothers because of them

sharing the same genetic makeup.

One of them is taken to space and the other is left on earth and their health

are studied to ascertain any change as a result of the environmental change

The first reaction of the body to a cut is to restore the continuity ?

Answers

Explanation:

First,blood cells called platelets join together at the paper cut and form a clot to stop the bleeding.The platelets then release chemicals called Cytokines into your blood stream.Cytokines attract the attention of certain cells to start healing your cut.

When the skin injured,our body sets into motion an automatic series of events,often reffered to as the " cascade of healing",in order to repair the injured tissues.The cascade of healing is divided into four overlapping phases:Hemostasis,Inflammatory,Poliferative,and Maturation.

Black fur colour is controlled by a dominant allele, B, and brown fur color by it's recessive allele, b. This characteristic is NOT sex linked. Give the genotypes of the parents and offspring of a cross between a black male and a brown female that produces 1/2 black offspring and 1/2 brown offspring.
Show all steps in working of this problem.​

Answers

Answer:

What are specialized cells

Bb and bb the genotypes of the parents and offspring of a cross between a black male and a brown female produce 1/2 black offspring and 1/2 brown offspring.

What is the dominant allele?

The connection between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent. One allele of a gene, known as the dominant gene, will be expressed if the alleles are different. The impact of the other allele, known as the recessive one, is concealed.

The Cross between parents is Bb x bb

Gametes- B and b

Offsprings- Bb, Bb, bb, bb

The crossing analysis is attached in the image below.

A person needs two copies of a recessive allele, one from each parent, in order for it to result in a recessive phenotype.

Therefore, Bb and bb the genotypes of the parents and offspring of a cross between a black male and a brown female produce 1/2 black offspring and 1/2 brown offspring.
