Answer:

Explanation:

Ibn Sina was an Islamic philosopher and scientist. There were many fields of research on which he worked but his services to the field of medicine are remarkable. Ibn Sina learned that patients who were sick with a particular type of disease could spread the disease from one person to another. He knew there was a factor involved in the spreading of diseases.

Ibn Sina wrote all his observations and findings in books which are of great importance even today.

How do the kidneys work to neutralize metabolic acidosis or alkalosis? If metabolic alkalosis exists, the kidneys slow their aci

melomori [17]

Answer:

Attaching letters to the options to make the question readable:

A. If metabolic alkalosis exists, the kidneys slow their acid excretion.

B. If metabolic alkalosis exists, the kidneys slow their acid retention.

C. If metabolic acidosis exists, the kidneys slow their acid excretion.

D. If metabolic acidosis exists, the kidneys increase their acid retention

The correct answer to the question above is option A (If metabolic alkalosis exists, the kidneys slow their acid excretion.)

Explanation:

Metabolic acidosis is a condition where there is an alteration in the acid-base balance in the blood. Here, as the name implies, a high level of acid than necessary are found in the blood as a product of metabolism caused by an increase in acid production, failure of acid to be expelled in the kidney.

Metabolic alkalosis is a condition where there is high level of alkaline in the blood than the body requires. Metabolic alkalosis occurs when the kidney is unable to excrete excessive alkaline in the blood and when there is too few acid-producing hydrogen ions present.

Kidneys fight metabolic acidosis by balancing acid levels in the blood by removing excessive acid in the blood through urine. It is also possible for the body to expel volatile acids through the lungs in the form of exhaled air.

Ways kidneys work to neutralize metabolic acidosis, ls If metabolic acidosis exists, the kidneys increase their acid excretion.

Ways kidneys work to neutralize metabolic alkalosis, is If metabolic alkalosis exists, the kidneys slow their acid excretion and increase their alkaline excretion or slow their alkaline retention.

In A Hydrogen ion pump the energy is used to join small molecules together to make larger ones which factor most likely has the

My name is Ann [436]

The factor that is most likely to have the greatest effect on the number of molecules mitochondria can produce is the number of H+ ions moving down the channel.
Hydrogen ions move from the outer to the inner compartment of the mitochondria through the electron transport system. The main purpose of the electron transport chain is to build up a surplus of hydrogen ions or protons in the inner membrane space so that there will be a concentration gradient compared to the matrix of the mitochondria. The concentration gradient helps in the generation of energy in the form of ATP.

Why don't all thermodynamically favored reactions occur rapidly?

serg [7]

solution:

Thermodynamically favorable reaction is the products, because the reaction occurs spontaneously, without the need for energy to be added.

Because a reaction is thermodynamically favoured does not mean that it will be a fast reaction. So 'yes' they always proceed but possibly infinitesimally slowly. Temperature is the most common way of quickening a reaction. Of course a catalyst also does so but this generally by changing the way the reaction occurs, i.e. the mechanism is different using a catalyst but the product is the same. Enzymes are natures catalysts, in synthetic chemistry (and in you car exhaust) metal based compounds are often used.

All reactions have an activation energy EaEa between reactants and products and a small increase in the size of this can slow a reaction exponentially. Experimentally, the rate constant is generally found be of the form k=k0exp(−Ea/RT)k=k0exp(−Ea/RT), which is the Arrhenius equation, with R the gas constant and T the temperature in Kelvin .

A human may go from being microscopic to being six feet tall in less than 16 years. What change on the cellular level accounts f

Karolina [17]

Answer: the number of cells increases

Explanation:

The changes experienced by a human, from birth to 16 years old in form of growth is facilitated by the increase in the number of cells.

Most tissues in the human body grow by increasing their cell number, but this growth is being monitored and regulated to maintain a balance between the different tissues.
