How does a loess affect the environment around it?

Answers

Answer:

Because loess is deposited from the atmosphere it provides an important geologic archive of past atmospheric circulation that can be used to test atmospheric circulation models

Explanation:

Answer:

Loess often collects in river headwaters, and subsequently gets carried to riverbeds. The buildup can be so dense, that it diverts the water over the adjacent flood plain. This may result in the flooding of rivers.

Cells use exocytosis to secrete molecules too large to pass through the cell membrane by any other mechanism. Some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic core. In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.

The two ways in which white blood cells fight pathogens that have entered the body are "they produce antibodies that work against the pathogens and they surround and destroy the pathogens".

What are pathogens?

Any organism as well as an agent that could cause the disease would be a pathogen in the widest and oldest sense.

What are antibodies?

Whenever the immune system of the body recognizes dangerous compounds, known as antibodies, it produces a protein designated an antibody.

Therefore, the two ways in which white blood cells fight pathogens that have entered the body are "they produce antibodies that work against the pathogens and they surround and destroy the pathogens".

Hence, the correct answer will be options (A) and (C).

Which of the following statements is FALSE regarding the effects of exercise on metabolism and body composition? Group of answer choices It slightly raises the metabolic rate for several hours after exercise. The increase in muscle mass raises the metabolic rate. It increases caloric expenditure and thus helps regulate body weight. It can result in substantial weight gain due to increase in muscle mass.

Answers

Answer: The false statement regarding the effect of exercise on metabolism and body composition is that (It can result in substantial weight gain due to increase in muscle mass).

Explanation:

Metabolism of the body simply means all the chemical reactions in all the cells of the body and the metabolic rate is normally expressed in terms of the rate of heat liberation during chemical reactions or physical activities.

The body composition of healthy adults who maintain stable body weight, energy intake is balanced with energy output. Energy output includes energy used for:

--> performing essential metabolic functions of the body.

--> performing various physical activities (exercise)

--> digesting, absorbing and processing food.

--> maintaining body temperature.

When an individual performs exercise, the rate at which heat is liberated( metabolic rate) is increased. This is because ATP which is gotten from the food is used as energy during exercise and is converted to heat as the end product.

Also, increase in muscle mass raises the metabolic rate because the more muscle in the body, the more calories are used up during rest and therefore the higher your metabolic rate.

Therefore the statement is false about the effects of exercise on metabolism and body composition because exercise involves energy output cannot lead to SUBSTANTIAL weight gain even in increased muscle mass.

What is one function of the organ system shown below in the picture?

Answers

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.

The circulatory and respiratory systems are involved in respiration. They provide oxygen to the body cells and remove carbon dioxyde. The correct option is A. To remove carbon dioxyde from the body.

Two systems work together when providing oxygen to the body cells and removing carbon dioxide: The circulatory and respiratory systems

• Respiratory system

This system is in charge of the gasses interchange. It takes oxygen from the air and releases carbon dioxide.

• Circulatory system

This system is in charge of driving oxygen to the organism's tissues and cells and taking away carbon dioxide from them.

These gases are in the oxygenated and deoxygenated blood, respectively.

The heart bombs blood through arteries, veins, and capillaries to the whole body.

The blood carries oxygen to different tissues.

This oxygen is absorbed in the lungs and proceeds from the air that we breathe. Its final destiny is all the cells in the organisms.

Types of circulation

• Lung circulation

1. Moves blood between the heart and the lungs.

2. Deoxygenated blood goes from the heart to the lungs

3. In the lungs, deoxygenated blood releases carbon dioxide and gets oxygenated again.

4. Carbon dioxide is released by exhalation.

5. Blood absorbs oxygen from small air sacs named alveoli.

6. Oxygenated blood returns to the heart.

Systemic circulation

1. Carries blood between the heart and the rest of the body.

2. Oxygenated blood leaves the heart and moves to all the cells in the body.

3. Deoxygenated blood returns from tissues to the heart.

According to thi framework, the function of the organ system shown in the picture is to remove carbon dioxyde from the body. Option A.

how enzymes inhibitions studies in the formulation and development of drugs​

Answers

Answer:

Enzyme inhibitors may alter the elimination rate of a particular drug or inhibit detoxication pathways

Explanation:

An enzyme inhibitor is a chemical compound capable of binding to an enzyme in order to reduce its activity. An enzyme inhibitor may bind to an active site and thus decreases the rate of reaction (direct inhibition). Enzyme inhibitors may act 1-to Inhibit detoxification enzymes and 2-reduce the elimination rate of enzyme drugs, thereby having dose-dependent toxicity effects. For example, many medicines are based on the inhibition of Cytochromes P450 (CYPs) proteins, which are a superfamily of enzymes required for drug metabolism.

D. lymphocytes activating plasma cells in the blood

Answers

The following answer in the equation is D

B. Inflammation at the site of an infection is an example of a nonspecific response of the immune system.

What is non-specific immune response?

Non-specific immune responses, also known as innate immunity, are the first line of defense against invading pathogens and are activated immediately upon exposure to a foreign invader. These responses are not specific to a particular pathogen and do not require previous exposure or recognition. Instead, they provide a general response that helps to prevent the spread of the pathogen and contains it until the specific adaptive immune response can be activated.

Examples of non-specific immune responses include physical barriers such as skin and mucous membranes, as well as physiological responses such as inflammation, fever, and the activity of phagocytic cells like macrophages, which engulf and destroy pathogens. Non-specific immune responses also include natural killer cells, which are able to recognize and kill infected cells, and the complement system, a group of proteins that help to enhance the ability of other components of the immune system to destroy pathogens.
