Answers

The water cycle is being polluted from many different sources such as the use of pesticides, which leech into run-off and can cause acid rain.
well that person above is kind of right except the water cycle does not make the water get like dirty it causes less water to be avalible to people

although the digestive system is primarily responsible for the breakdown of food, this process can be disrupted if the circulatory system malfunctions. The best explanation for this disruption is that

Answers

Final answer:

The circulatory system plays a crucial role in carrying the nutrients absorbed by the digestive system to different parts of the body via the bloodstream. A malfunction in the circulatory system can interrupt the transportation of these nutrients, consequently disrupting the digestive process.

Explanation:

The digestive and circulatory systems are interconnected in the human body. Digestive process involves breaking down food into tiny particles that can be absorbed into the bloodstream. This occurs primarily in the small intestine, where most nutrients are absorbed from the alimentary canal into the bloodstream through the epithelial cells that make up the mucosa.

However, when the circulatory system malfunctions, it disrupts the absorption of these nutrients. The circulatory system is responsible for distributing these nutrients to the different parts of the body. If it malfunctions, nutrient distribution is affected, thereby hampering overall bodily function including the digestive process.

For instance, the circulatory system plays a crucial role in carrying the absorbed nutrients from the small intestine to different parts of the body for use. This is done via the bloodstream. Therefore, a malfunction in the circulatory system can hinder this important process and subsequently disrupt the digestive system.

A student examines a cell under the microscope and determines that it is a eukaryote. All but one structure could help the student come to this conclusion. Which structure is of no help?A) cell wall
B) Golgi body
C) mitochondrion
D) membrane-bound nucleus

Answers

Answer:

A) cell wall

Explanation:

The cell wall does not help differentiate prokaryotic cells from eukaryotic cells, since both have the cell wall (formed by polysaccharides and amino acids).

The other structures help identify the eukaryotic cell due to the fact that only this type of cell has them, while prokaryotic cells lack organelles such as mitochondria and the golgi complex.

In addition, prokaryotes do not have membrane-bound nuclei, and due to their less complex structure, their genetic material is dispersed in the cytoplasm.

Answer:

the answer must be A.

People with diabetes often receive insulin injections. What effect does insulin have on the body?

Answers

Answer:

Insulin is secreted by the pancreas which regulates the blood glucose level in the blood. Insulin generally reduces the blood glucose level by depositing the glucose in the liver and muscles as glycogen.

In diabetic people, enough insulin is not produced by the pancreas as a result glucose level increases in the blood which is called hyperglycemia. So in this condition, insulin injection is given from outside to increase the level of insulin in the blood.

Then this increased level of insulin helps in reducing the extra amount of insulin from the blood by accumulation it on the liver. Therefore insulin play a role in reducing the extra amount of free glucose from the blood.
It has the same affect as insulin that the body produces. It reacts with glucagon (I think. It is that or gycogen) to create glucose
