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.

In dividing cells, most of the cell's growth occurs during “_____”
Answers
Answer:
In dividing cells, most of the cell's growth occurs during interphase. 5. The mitotic spindle(s) is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division.
During interphase, DNA replication and cell expansion take place. During the mitotic phase, the cell divides and the DNA replication and cytoplasm are segregated.
What is the role of interphase in cell growth?The majority of a cell's time is spent in the phase known as interphase, during which it matures, copies its chromosomes, and prepares to divide. The cell then completes mitosis, leaves interphase, and divides to completion.
During the mitotic (M) phase, the cell splits into two new cells by dividing its cytoplasm and DNA into two sets.
Chromosomes will line up, split, and move into new daughter cells during mitosis. Interphase occurs between one mitotic (M) phase and the next because the prefix inter- signifies between.
Therefore, in dividing cells, most of the cell's growth occurs during interphase.

What is one function of the organ system shown below in the picture?
Answers
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 systemThis system is in charge of the gasses interchange. It takes oxygen from the air and releases carbon dioxide.
• Circulatory systemThis 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.

the fluid outside the cell membrane is called what? —-> tissue fluid
im not toooooo sure about the second one buttt i tired lil
In a cell, the fluid within the cell membrane is called cytoplasm, and the fluid Outside the cell membrane is called interstitial fluid. The correct option is A.
What is cytoplasm?The gelatinous solvent that fills the inside of a cell is known as cytoplasm. It is made up of water, salts, and organic molecules.
Certain intracellular organelles, including the nucleus as well as the mitochondria, are separated from the cytoplasm by membranes.
The cytoplasm of a cell performs all functions related to cell expansion, growth, and replication.
Interstitial fluid can be found in the spaces between cells. It is caused by substances leaking from blood capillaries.
It aids in the delivery of oxygen and nutrients to cells as well as the removal of waste products.
Glucose, salt, fatty acids, and minerals such as calcium, magnesium, and potassium are all found in interstitial fluid.
Interstitial fluid contains nutrients from blood capillaries. It can also contain waste products from metabolism.
Thus, the correct option is 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.

The immune system has two modalities, specific and nonspecific responses. Which of the following is an example of a nonspecific response?
A. an antigen binding to an antibody
B. inflammation at the site of an infection
C. a cytotoxic T cell attacking a pathogenic agent
D. lymphocytes activating plasma cells in the blood
Answers
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.
