Which kind of muscle fibers enable the muscles to exert force for a long period of time? fast twitch slow twitch

Answers

Answer 1

Answer:

The correct answer is slow twitch.

There are generally two types of skeletal muscle fibers present in the body of humans. These are slow twitch fibers and the fast twitch fibers. The slow twitch fibers in the muscle allow the long endurance responses to the muscles, on the other hand, the fast twitch fibers generate a fast response in the muscles.

Answer 2

Answer: The question says, which kind of muscle fiber enable the muscle to exert force for a long period of time. The correct option is 'slow switch'. The slow switch muscle enable one to participate in long endurance feats such as long distance running. These muscles are red in colour because of the high quantity of myoglobin found in them.

Which of following is not essential part of virus?

Answers

Envelope is not essential part of virus (option B)

What is virus?

A virus is a small, infectious agent that can replicate only inside the cells of living hosts. Viruses are not considered living organisms because they do not have their own metabolism or cell structure.

The essential parts of a virus are:

Nucleic acid: This is the genetic material of the virus, which can be either DNA or RNA. The nucleic acid carries the instructions for making new viruses.

Capsid: This is the protein coat that surrounds the nucleic acid. The capsid protects the nucleic acid and helps it to attach to host cells.

A human skin cell contains 46 chromosomes. Afrog sperm cell contains 12 chromosomes.
Which pair of numbers shows the chromosome
number of a normal gamete from each of these
species?
(1) human 46; frog 12 (3) human 23; frog 24
(2) human 46; frog 24 (4) human 23; frog 12

Answers

The number of chromosomes for the gamete of each of the species would be half of that of their vegetative cells.

Haploid cells

Haploid cells contain half (n) the number of chromosomes of diploid cells (2n)

Gametes are generally haploid in nature.

The human skin cells are vegetative cells (2n), thus a gamete of humans would have 23 or (46/2) chromosomes.

The frog sperm cell is a gamete cell. Hence, the chromosome number remains 12.

In other words, human gametes will have 23 chromosomes while frog gametes will have 12.

More on haploid cells can be found here: brainly.com/question/15475325

Answer: Human 23; frog 12

Explanation: Skin cells are somatic cells, that means the they build the body and divide by mitosis. This kind of cells have genetic charge 2n or twice of the gamete's chromosomes, so a human gamete (sperm or ovum) has 23 chromosomes (46/2 = 23).

Frog sperm cell is a gamete so it has the number of chromosomes for this type of cell which is 12
