Bob has brown hair and Sally has blonde hair. If brown hair is dominant and blonde hair is recessive, is it possible for Bob and Sally to have a blonde-haired child? Use the GENOTYPE of each parent to EXPLAIN your answer.

Answers

Answer 1

Answer:

no it is not possible

Explanation:

bc when you do a punnett square brown hair is dominant so there is not a possible way for their child to have blonde.

Answer 2
yes it is, let’s say B - is for brown hair and b - is for blonde hair
to have blonde hair they would have to have a bb genotype meaning that if bob had the Bb genotype then sally and bob have a 1/4th chance of having a blonde haired child

Colonial species are together

The group of unicellular organisms that live together but have no relation to one another is called colonial organisms.

What are colonial organisms?

The organization of cells leads to their efficiency. The organization of cells leads to the formation of tissues and organs which leads to the efficient functioning of an organism.

The organization of cells is not only seen in the multicellular level of organization. It starts from the organization of molecules to form structures like proteins and nucleic acid.

Unicellular organisms are able to live and survive independently and perform all life processes necessary for their own survival. But, bacteria are often found to live together in colonies.

A colony is a group of individual organisms that live close to each other. They live together because they are stronger in a colony. A colony of bacteria can protect themselves, acquire their nutrition or attack a host in a better way.

Therefore, a group of organisms who live close to each other and have no relationship is called colonial organisms.

briefly describe how you can tell when you are repaying the oxygen deficit

Answers

You are repaying the oxygen deficit when you have elaborated breath after a long workout.

We can define oxygen deficit as the difference between the oxygen that our body needs during a workout and the one that it gets, which is not enough.

We can tell when our body is repaying the oxygen deficit when our breath is elaborated. What our body is trying to do is to expel carbon dioxide and take as much oxygen as it needs with quick and short breaths.

In conclusion, elaborated breath is a sign that we are repaying the oxygen deficit.

why is the concentration of oxygen in the body cells lower than the concentration of oxygen in the alveolus?

A. Alveolus can produce oxygen.
B. The exchange of gases occur in the alveolus.
C. Oxygen is used up for respiration I the body cells.
S. Oxygen diffuses out from the body cells.​

Answers

Answer:

i think the answer should be b.

the alveolus is the site of exchange of gases (carbon dioxide and oxygen) between the body cells and the alveolar air. diffusion requires a concentration gradient, which basically means that there has to be a difference in concentration of the substance (in this case it's oxygen) between the 2 areas (in this case it's the body cells and the alveolar air) hence, there is more oxygen in the alveolar air than the body cells (this difference in concentration is what allows diffusion of oxygen from a region of HIGHER to LOWER concentration!) this allows oxygen to diffuse from alveolus to body cells, giving your body the oxygen it needs!

btw keep in mind that i am by no means an expert in biology (because im still a student), but b is the most logical answer to me. good luck!

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.

How could the changes made to the amino acid sequence influence phenotype changes?​

Answers

Due to change in sequence there would be change in Protein structure hence in phenotype

A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.

Protein structure orders

The sequence of a protein is determined by the DNA of the gene that encodes that protein (or that encodes a portion of the protein, for multi-subunit proteins).

A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.

Even changing just one amino acid in the protein sequence can affect the protein's overall structure and function. For example, a single amino acid change is associated with sickle cell anemia, an inherited disease that affects red blood cells.
