Blood flow has stopped completely which is causing his severe headaches due to lack of blood reaching the brain.C. Blood flow has increased in order to makeup for his lack of exerciseD. Blood flow is decreased below normal due to the build of of plaque in the arteries causing an increase in blood pressure.

Answers

Answer:

Blood flow is decreased below normal due to the build of of plaque in the arteries causing an increase in blood pressure.

Explanation:

When fats, cholesterol,calcium , water  builds up on the endothelial lining of the  Coronary arteries,reducing the diameter,and therefore impeding the flow of blood,these build up is called Plaque.The diseases condition that arise  from this called atherosclerosis.

With continue build up the plaque changes in the chemical components.becomes hardened, further reducing the diameter,blood volume available and therefore oxygen supply to the targeted tissues( cardiac muscles) of the heart.This leads to Ischemic heart diseases e.g chest pain-Angina. With these strokes and other complication may follows due to cut  off in oxygen and nutrients rich blood to the tissues of the brains  for the heart.

The impedance to the blood flow,forced load on the heart to pump blood and therefore High blood pressure.This is the problem with Steve CVS.

Answers

Answer:

What role did endosymbiosis play in the evolution of eukaryotes? Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts.  This kind of natural selection led to the evolution of eukaryotic cells and the plants and animals we see today.

Explanation:

Endosymbiosis is important because it is a theory that explains the origin of chloroplast and mitochondria. It is also a theory that explains how eukaryotic cells came to be. DNA, RNA, Ribosomes and Protein Synthesis

This provided the first substantial evidence for the endosymbiotic hypothesis. It was also determined that mitochondria and chloroplasts divide independently of the cell they live in.

Which of these statements about molecules is true? A. All molecules only contain one element
B. Two or more molecules can combine to form an atom
C.the elements in a molecule are always present in equal proportions.
D. The atoms in a molecule cannot be separated from each other by physical means

Answers

Answer:

D

Explanation:

The atoms in a molecule cannot be separated from each other by the means of physical force because they are bound to each other through chemical bonds. Thus, the correct option is D.

What are molecules?

Molecules are a group of two or more similar or different atoms that form the smallest identifiable unit which can be divided into pure substances such as atoms. Molecules retain the composition and chemical properties of the substance from which it is built.

Molecules can be homogenous or heterogenous depending upon the constituent atoms. If different atoms combine to form a molecule then it is heterogenous in nature e.g., CO₂ while the molecule which is made up one type of atom is known as homogenous. Example- O₃.

Molecules have chemical bonds which are responsible for the binding of atoms, these chemical bonds can be broken by applying energy in the form of heat to the molecules.

Therefore, the correct option is D.

HELP ME ASAP HELP ME PLZZZ HELP MEEEEEEEEE

Answers

Answer:

Precise, but not accurate

Explanation:

First, let's define precision and accuracy.

Precision: how close multiple measurements are

Accuracy: how close the measurements are to the true measurement

The three measurements are:

167.0 g, 166.9 g, 167.2 g

The true mass is 172 grams.

We can see that each measurement is far from the actual value of 172 grams: about 5 grams off. They are not close to the actual measurement, so they are not accurate.

The three measurements are very close to each other. They are all within 0.3 grams of each other. The measurements are all close to each other, therefore they are precise.

Therefore, the measurements are precise, but not accurate.

Answer:

More precise than accurate.

Explanation:

Precision is a measurement of how close your measurements to each other, accuracy is a measurement of how close your measurements are to the true value.

How does a virus get into the cell?​

Answers

Answer:

A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host—and the cells within the host—that can be infected by a particular virus.

Answer:

Viruses initially stick to cell membranes through interactions unrelated to fusion proteins. The virus surfs along the fluid surface of the cell and eventually the viral fusion proteins bind to receptor molecules on the cell membrane (4). If only binding occurred, the two membranes would remain distinct.

During diffusion, molecules move from areas of Higher concentration to areas of Lower concentration. Diffusion does not require to move molecules. As

Answers

Answer:

The diffusion of molecules is a process that happens in our organism and the solutes move in a single direction that is always respected based on the principles of biochemistry.

Solutes always move or diffuse from compartments of higher concentration to those of lower concentration in order to equalize the amount of solute in both compartments and therefore equalize the concentrations.

Explanation:

These processes must take place between two compartments of different concentrations divided by a selective semi-permeable membrane, that is, only the solute passes and diffuses passively or actively without dragging on water or other molecules.

This process occurs in the body in those with hyper concentration of solutes in the blood in pharmacological situations.
