Which is a component of cell theory?

1) Cells come from bacteria.
2) Cells come from cells.
3) Cells come from nonliving matter.
4) Cells come from non-cells.

Answers

Answer 1

Answer:

A postulate that is part of the cell theory is cells come from cells (option 2).

Explanation:

The third postulate of the cell theory is "All cells originate from other cells".

After Schleiden and Scwann proposed the first postulates of the cell theory, in 1863 the anatomist Rudolf Virchow observed how cells were able to reproduce themselves and give rise to new cells, in the context of his studies on cancer. The third postulate of the theory is due to this scientist, who was able to conclude that every living cell originates from another cell.

The three postulates of the cell theory are:

Cell is the basic structural and functional unit of life. All living beings are made up of one or more cells. All cells originate from other cells.

Based on this contribution from three scientists, the foundations of cell biology were laid.

The other options are not correct because:

Cells como from bacteria, non-living matter or non-cells are part of theories about the origin of cells.

b
Protect our bodies from harmful substances, senses temperature and pain, regulates body temperature, and removes wastes
c
Transport materials such as nutrients, hormones, and water throughout the body
d
Break food down into small enough molecules for the cells of your body to absorb.

Answers

Answer:

1. The function of the Integumentary System is to protect the bodies from harmful substances, senses temperature and pain, regulates body temperature, and removes wastes (b).

2. The function of the Immune System is protect the body from harmful substances and infection (a).

Explanation:

The integumentary system includes the skin and skin annexes. The skin covers the entire body and therefore provides protection, avoiding contact with harmful agents and acting as a barrier that protects the internal tissues. Other functions of the skin include

It contains the nerve endings that allow the relationship function, with receptors for touch, temperature and pain. It acts as a thermal insulator, and allows the regulation of body temperature. It is a way to eliminate waste, through sweating.

The immune system is made up of a group of cells —neutrophils and lymphocytes— and substances that are responsible for protecting the body.

This system is capable of identifying and eliminating any harmful or infectious agent -such as bacteria, viruses, parasites and fungi- through cellular or humoral action, the latter including antibodies and cytokines.

The other options, for both systems, are not correct because:

    C. The transport of nutrients, hormones and water throughout the body is a function of the circulatory system.

    D. Breaking down food to obtain molecules that can be absorbed is a function of the digestive system.

Which best explains why a patient who had a myocardial infarction will never fully recover, in spite of all the drugs prescribed to him? The drugs are only effective for extremely active, healthy individuals. The drugs cannot rebuild the cells that died, but they can limit the death of more. The drugs restore blood flow to some of the arteries, but not arteries in the legs. The drugs prevent another heart attack, but other damage has already occurred.

Answers

Answer:

A patient with a myocardial infarction cannot fully recover, despite the drugs he takes because the drugs prevent another heart attack, but other damage has already occurred.

Explanation:

Myocardial infarction is due to a blockage of the coronary arteries, with an absence of blood supply to areas of the heart muscle that end up dying.

A person with a myocardial infarction will not be able to recover the damaged areas of his heart —since the damage has occurred— but drugs are useful to decrease cardiac risk factors, improve coronary circulation and prevent a new attack.

The other options are not correct because:

Myocardial infarction drugs are used in people with cardiovascular disease, not in very active healthy people. If a drug restores blood flow, it does so throughout the body. The drugs cannot rebuild the cells that died, but they can limit the death of more, does not explain why the patient with a heart attack does not fully recover.

Answers

Answer:

There is nothing wrong with generic medicines. The coating of the tablet might differ or the dosages but essentially it is the same medication.

Answer: include the same active ingredients as the original medication

Explanation: A generic drug must contain the same active ingredients and must be equivalent in strength and dosage to the original brand name.

If somebody can help me with this test I will cash app you $5 if u get all the answer right

Answers

I'm pretty sure its All Of The Above!

Hope this helps <3

Answer:

c. all of the above

Explanation:

The uterine tubes, also known as the fallopian tubes, are part of the female reproductive system. They are muscular tubes that are open ended at one end and end at the uterus.

These muscular tubes are how the egg travels down from the ovary to the uterus after ovulation. It does so via the cilia and peristaltic waves.

They are the site of fertilization (if fertilization is to occur). The fertilized egg later implants into the uterus for the embryo to develop.

All the statements are correct.
