Answer:

The correct answer is - cells of the immune system recognizing the tumorous cells as foreign and destroying them.

Explanation:

Cancerous cells are the cells in which the normal inhibiting normal growth control or increasing the cell division. Due to this rapid growth, the cancerous cells often produce glycolcalyx that can result in destroying these cells react to these cancerous cells as foreign bodies and destroyed it.

Thus, the correct answer is first statement.

Cancerous cells can divide so rapidly that they will often produce a glycocalyx that is different than the other cells in the body. This may result in allowing the cancer cells to bind to their healthy, neighboring cells. Cancer is unchecked growth of cells. Cancer is caused by mutations in genes accelerating the rate of cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.

Ingestion of foreign substances by macrophages and yeast cells by an amoeba is known as
Iteru [2.4K]

Ingestion of foreign substances by macrophages and yeast cells by an amoeba is known as <u>Phagocytosis</u>

<u>Explanation:</u>

Phagocytosis that is the name given to the process of ingestion of foreign particles by macrophages. In human body the white blood cells does this function. Macrophages is found in all the tissues. Any foreign particle entering the body is engulfed by this process hence protecting the organisms.

Once a bacteria enters the body it is at once detected and recognised as the foreign particle. Then it is attached to the phagocyte. Then it is engulfed into a vesicle called phagosome. Then this is killed by the process of phagocytosis.

Sonja [21]

Answer: b. Increased nutrient run-off

Explanation:

Nutrient run-off is when an excessive amount of nutrients like Nitrogen and Phosphorous find themselves in bodies of water. This acts as a fertlizers and promotes algae growth.

This algae growth compromises the qualiy of water and depletes the oxygen in the water. This essenfially harms the habitat thus this is noy an ecological benefit.

Gekata [30.6K]

Answer:

The options

A. A

B. B

C. C

D. E

The CORRECT ANSWER IS D.

E.

Explanation:

It is a regular occurrence for dialysis bags or dialysis tubing to be employed in permitting smooth movement of molecules when having to do with a fluid. These bags are normally evaluated to ensure that the client has adequate amount in th bag so as to be able to achieve the goal at hand.

If we have five dialysis bags being formed from a semi-permeable membrane which is impermeable to sucrose, they may be saturated with different concentrations of the sucrose with each of these bags being positioned in different beakers that have an initial amount of 0.6 M of a sucrose solution.

At ten minute intervals, the bags were massed and the weight was calculated to look for changes in the level of concentration. In this situation, the bag with the lowest initial concentration of sucrose is be the one that has its mass reducing over time and that is E.

The attached image confirms our answer as from the graph, option E shows the lowest initial concentration of sucrose.

A hypothesis is a general principle or explanation that is derived from observations. Suppose you make the following observation
mr_godi [17]

Question continued

For each statement below, mark "True" if it would be a valid hypothesis, based on these three observations alone, and mark "False" if it would not be a valid hypothesis.

1. The onion cells I looked at have a nucleus.

2. All onion cells have a nucleus.

3. All cells have a nucleus.

4. Some cells have a nucleus.

5. Only onion cells have a nucleus.

6. If I look at 10 skin cells from my hand, each one will have a nucleus.

Answer:

1. The onion cells I looked at have a nucleus. false - this is not a hypothesis, it is an observation of the evidence you collected.

2. All onion cells have a nucleus. true - this is a valid hypothesis based on the evidence you have gathered from looking at onions

3. All cells have a nucleus. true  - this is a hypothesis based on you looking at 3 cell types, several samples of each, and finding that they all have a nucleus

4. Some cells have a nucleus. false - this is not a valid hypothesis. Your evidence so far suggests all cells have a nucleus

5. Only onion cells have a nucleus. - false, you know this to be false as other cell types you analysed had a nucleus

6. If I look at 10 skin cells from my hand, each one will have a nucleus. false - a hypothesis is supposed to be a general principle that is backed up by evidence, this is too specific.
