What are the functions and vessels of the heart, and what are some cardiac disorders that might be life-threatening to a person

zavuch27 [327]

Answer:

The cardiovascular, or circulatory, the system supplies the body with blood. It consists of the heart, arteries, veins, and capillaries. but the things that might be life-threatening to a person or animal are;

Explanation: angina is a type of chest pain that occurs due to decreased blood flow into the heart this can harm animals and people. there is also - - - arrhythmia,which is or an irregular heartbeat or heart rhythm,

- congenital heart disease, in which a problem with heart function or structure is present from birth.

-coronary artery disease, which affects the arteries that feed the heart muscle.

- Heart attack, or a sudden blockage to the heart’s blood flow and oxygen supply this can kill. heart failure, wherein the heart cannot contract or relax normally,

- dilated cardiomyopathy, a type of heart failure, in which the heart gets larger and cannot pump blood efficiently and the last one is

- hypertrophic cardiomyopathy, in which the heart muscle walls thicken and problems with the relaxation of the muscle, blood flow, and electrical instability develop

these are only a few that can harm or even kill a living thing like and animal or person these things are really harmful.

I hope this helps you!!

A group of cells is assayed for DNA content immediately following mitosis and is found to have an average of 4 picograms of DNA

damaskus [11]

Answer:

b: 8;8

Explanation:

Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;

the $G_0$ phase,
the $G_1$ phase,
the S phase; and
the $G_2$ phase.

The $G_0$ phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.

Actively dividing cells enter the $G_1$ phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the $G_2$ phase where proteins are synthesized in preparation for division or m phase.

At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.

Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of $G_2$ phase.

The correct option is b.

In-s [12.5K]

Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells

Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.

when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.

Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
