Which type of mutation occurs in reproductive cells and can be passed to offspring:?A.somatic mutationB.germline mutationC.point mutationD.frameshift mutation

Answers

Answer 1
Answer:

The answer is B. germline mutation. 


The germline mutation is heritable variation in the lineage of reproductive (germ) cells. Germ cells are cells that give rise to the gametes, so a mutation in germ cell will be seen in a sperm cell or egg cell but not in a skin cell, for example.


The point mutation is the changes in a single nucleotide base on the DNA molecule.

Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and totally different translation

Somatic mutation is mutation in a somatic cells and is not passed on to the next generation.

Which conditions relate to the research of van Helmont

Answers

The VanHelmont experiment consists of a measure of the amount of soil before and after a plant grows.

He wants to demonstrate the independence of soil.

After five years he measures the amount of soil and only 2oz gone from the initial amount of soil when the plant weight much more.

The conclusion was the plant use water to grow, and not the soil.

Afterward, he discovers CO2 but, not until the discovery of photosynthesis we all knew how everything in plants works.

How do the quantities of ATP formed during aerobic and anaerobic respiration compare? A. Two times more ATP is formed during aerobic respiration than during anaerobic respiration. B. Four times more ATP is formed during aerobic respiration than during anaerobic respiration. C. Eight times more ATP is formed during aerobic respiration than during anaerobic respiration. D. Eighteen times more ATP is formed during aerobic respiration than during anaerobic respiration.

Answers

Answer:

The correct option is D. Eighteen times more ATP is formed during aerobic respiration than during anaerobic respiration.

Explanation:

Aerobic respiration can be described as the process of respiration taking place in the presence of oxygen. This process makes a lot more energy as compared to anaerobic respiration.

Anaerobic respiration can be described as the process of respiration taking place in the absence of oxygen. This process is one of the earliest reactions that occurred in organisms since the formation of life.

The process of aerobic respiration releases 38 ATP per glucose whereas the process of anaerobic respiration releases 2 ATP molecules per glucose. Hence, the ATP formed during aerobic respiration is approx 18 times more than the anaerobic respiration.

Which structure secretes hormones directly into the bloodstream without using a duct?

Answers

The answer is endocrine glands.

There are two types of glands - endocrine and exocrine glands. Endocrine glands secrete hormones directly into the bloodstream without using a duct, while exocrine glands secrete hormones through the duct. Endocrine glands include pancreas, hypothalamus, pineal gland, pituitary gland, thyroid gland, parathyroid gland, adrenal gland, ovaries, testes.

A plant with round seeds is crossed with another plant with round seeds. Round are dominant over oval seeds. When two heterozygous round-seeded plants are crossed, what is expected of their offspring, assuming random chromosome segregation?

Answers

Because the plants are heterozygous their alleles will be Ss (for example) Therefore if you crossed them over your possible outcome would be SS, Ss, Ss, and ss. Because the round seeds are dominant (shown as the capital S) this means that if the S is shown then the plant will have ROUND seeds. Therefore in this situation 3/4 of all the offspring would have round seeds.
