Which courses should Don take in high school if he wants to pursue a degree and career in molecular biology? O anatomy and neurobiology O immunology and genetics O history and communications O physics and trigonometry​

Answers

Answer:

anatomy and neurobiology

Explanation:

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.

Successful molecular biologists have an excellent understanding of subjects such as cell physiology, chemistry, genetics, and physics.

A neuroscientist (or neurobiologist) is a scientist who has specialised knowledge in the field of neuroscience, the branch of biology that deals with the physiology, biochemistry, psychology, anatomy and molecular biology of neurons, neural circuits, and glial cells and especially their behavioral, biological, and psychological aspect in health and disease.

Anatomy and neurobiology are the best for what he wants to do

To melt the ice during the winter season, road crews often put sand and salt solutions on the roadways to help melt the snow and ice. The plants that live close to the road often die or wilt after this procedure. Using your knowledge of osmosis and plant structures, which type of solution would cause this to happen to plant cells? Group of answer choices

Answers

Answer:

The missing answer choices are:

a. hypotonic

b. isotonic

c. osmosis

d. hypertonic

The correct option is d. hypertonic

Explanation:

A hypertonic solution has a higher concentration of solutes than the concentration of solutes present inside the plant. As there is a difference in concentration between the inside and the outside of the plant, the plant loses water in an attempt to balance the difference. As a result, there is an excessive loss of water that dehydrates the plant and kills it.

SUBMIT
PLEASE HELP

Answers

Answer:

The correct answer is - B. An allele present in all members of a population.

Explanation:

A homzygous variant or allele for all the members of a particular gene is a fixed gene and is the only variant that presents in all the population for that gene.

It takes place when there is all other alleles become extinct and only one remains. The allele frequency of this allele is always 1.00 in the population which means only one allele is present on the locus.

Which class of point mutation produces a product with the same amino acid sequence as the wild-type polypeptide?

Answers

Answer:

The correct answer is - silent.

Explanation:

Silent mutation is a point mutation that takes place by a single change in a single base nucleotide of nucleic acid and it may or may not change the aminoacid sequence as the wild type protein.

This does not result in any phenotypic or functional change in the protein of the organism. It is a class of point mutation. This change can be substitution in base.

Explanation:

Genetic variation refers to the variations that exists in the DNA of the individuals. These variations are caused mainly by mutation and genetic recombination of the DNA. It helps in the process of evolution. Genetic variations helps in building the mechanisms of change that helps in the process of evolution. Genetic variation is caused highly because of process of sexual reproduction. The offspring exhibit various genetic variation.

Answers

Answer:

25%

Explanation:

If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.

Create a punnett square to find possible offspring

AA = Blood type A

AO = Blood type A

OO = Blood type O

There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.

1÷4×100 = 25
