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

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
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.

Which of these would be a disadvantage when forming a fossil? hard body parts buried quickly high oxygen atmosphere high pressure
Answer:
c
Explanation:
usatestprep
The disadvantage when forming a fossil is a high oxygen atmosphere, which is the second option, as the high oxygen atmosphere can lead to the rapid decay of organic matter, making it less likely to be preserved.
What is a fossil?Because oxygen is a reactive gas that can decompose organic material when exposed to high temperatures and pressures, fossils will be destroyed in such a climate, which is why fossils are more commonly found in environments with low oxygen levels, such as deep underwater sediments or anaerobic environments like swamps and bogs. One of the main factors that determines whether or not an organism will be fossilized is the speed at which it is buried after death, if an organism is buried quickly, it is less likely to be disturbed or exposed to scavengers.
Hence, the disadvantage when forming a fossil is a high oxygen atmosphere, which is the second option.

The stage of the stress response in which the pituitary gland releases a flood of adrenocorticotropic hormones is
Answer:
This is Alarm.
Explanation:
Adrenocorticotropic hormones and stress.
This the hormones secreted at the corticotrophs cells of the anterior pituitary glands.Its major function is to ensure the efficient functioning of the Adrenal gland and body response to stress.It is also mediate the secretion of cortisol from the cortex of the adrenal gland into the blood stream.When it is released into the blood streams it binds to the receptors in the adrenal gland to stimulate the release of cortisol hormone.
ACTH controls diurnal (circadian) rhythm in human.This is because it peaks in the morning and progressively reduced towards the end of the day,with lowest concentration during period of sleeping.
Generally stress either by dehydration or internal complications,leads to increase in solute potential of the blood.Stress increases the activation of ACTH from the adrenal gland while boosting the concentration of cortisol. When the stress is sensed by the brain,this causes the release of corticotrophin-releasing hormone into the bllood.
The latter cause the discharge into the blood stream of ACTH via hypothalamic–pituitary–adrenal (HPA) axis.As this enters the blood it binds to the receptors for the cortisol secretions in the cortex of the adrenal gland to produce cortisol as explained earlier.Cortisol is the primary sex hormone which create the alarm.

Periods are rows in the periodic table. The number of Valence electrons grows across the period (left to right) until reaching the electron shell's capacity.
Groups occur in columns in the periodic table and all have the same number of valence electrons, and the number of electron shells increase as you move downward on the table
Steve is a 47 year old male who has a lot of plaque buildup in his arteries due to lack of exercise and a diet high in fats. He has recently been complaining of vision problems, chest pain, and severe headaches. His doctor informs him in his latest visit that his blood pressure is too high for his current age. What is most likely happening to the flow of blood in Steve's cardiovascular system?A. Blood flow is continuing like normal and is not affected by his high blood pressure.B. 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.
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.
