Answer:

The correct answer is B. Single-nucleus, striated, branching cells.

Explanation:

This is because the heart has to communicate with itself, and to do that, it has to have branching cells. In addition, the heart has to continue pumping all of the time for many years, so the structure has to be thick and sturdy.

Hope this helps!

Answer:

The correct option is B.

Explanation:

Muscle tissues of the heart refers to a group of cells that are carrying out similar functions in the heart. There are three different types of muscles, these are skeletal, cardiac and smooth muscles. The cardiac muscles are found in the heart, they form the contractile wall of the heart. These muscle contract involuntarily ( that is, without any external stimulation) and they are single nucleus, striated and short.

Answer:

B) The normal pH of blood is 6.8 to 7.0.

The blood pH under normal health conditions is between 7.35 and 7.45. Below this range, blood pH is considered more acidic than normal, and it may indicate that the body is eliminating a lower amount of CO{2} than normal, or that there is a decrease in the concentration of HCO{3-} or accumulation of acid in the blood due to poisoning or disease.

kykrilka [37]

Answer:

The answer is A.

Explanation:

To test if the selenium from the mine has an effect on the fish living in the lake which i assume is close to the mine, testing the tissue of the fish from that lake and comparing it to the selenium levels of the fish from a nearby lake would be a testable hypothesis because there is a comparable aspect and there should be a difference in the numbers between the fish from the two lakes because of their distance to the mine.

I hope this answer helps.

Anastasy [175]

In cardiac muscle

a. an action potential spreads throughout the Z discs.

b. intercalated discs connect the muscle fibers together.

c. calcium enters the cell from storage chambers called intercalated discs.

d. potassium is released from the sarcoplasmic reticulum

Answer:

b. intercalated discs connect the muscle fibers together.

Explanation:

Intercalated discs are components of the muscles found in the heart(cardiac muscles).

Intercalated discs join the cardiomyoctes (muscle cells or fibers) together so that they can function as one and transmit signals amongst themselves during the contraction of the heart.

Intercalated discs are made of up desmosomes and gap junctions.

Intercalated discs are found on the lining of the sacromere and can only be seen by using a microscope to observe the longitudinal section of the heart tissue.
