Answer:

Adenine (A) = 28%

Cytosine (C) = 22%

Explanation:

The DNA molecule, which is the genetic material that stores or holds information needed by the cell for growth, reproduction etc. Structurally, the DNA is composed of nucleotide subunits, which are of four types namely; Adenine, Guanine, Cytosine, and Thymine etc.

According to Chargaff in his complementary base pairing rule, he states that Adenine will always pair with Thymine (A-T) while Guanine will always pair with Cytosine (G-C). Based on this, Chargaff further stated that the amount of adenine must be equal with that of thymine while that of guanine must be equal to cytosine.

In total, their total amount must be equal to 1 or 100% i.e. (A + T) + (G + C) = 100%. In this question, 22% of Guanine are found in the DNA of a fox. This means that automatically, the percentage of cytosine is 22%. We then calculate the amount of Adenine and Thymine as follows:

(A + T) + (G + C) = 100%

A + T + 22 + 22 = 100

A + T + 44 = 100

A + T = 100 - 44

A + T = 56

Since A = T,

56/2 = 28

Hence, A = 28%, T = 28%

Answer:

These are striated skeletal muscles.

Explanation:

support and movement. There is an attachment to the skeleton to help move limbs, usually connected from bone to limbs..cross striations with dark A bands & light I bands. The Z line stands out in the center of I bands...hope this helps..

These muscles are striated which help in supporting and assisting the skeleton's movement. So, the correct option is A.

Highly organised tissues called striated muscles are responsible for converting chemical energy into muscular work. Striated muscles have two main purposes: to pump blood through the body (cardiac muscle) and to produce force and contract in support of breathing, movement, and posture (skeletal muscle).

They have striations, which are alternate bands of light or dark. The muscles of the face, the neck, limbs, etc. contain striated muscles. Additionally, the pharynx, tongue, diaphragm, the upper part of the esophagus all contain them. In the given example, these muscles are striated which help in supporting and assisting the skeleton's movement.

Therefore, the correct option is A.

Answer:

when it's born a star is born when it's born

Answer:

A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin

Explanation:

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.

Answer:

O They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.

Explanation:

Lipids do not contain nitrogen groups and do not have polar glycosidic bonds. In addition, the function of cellular membranes depend greatly on the fact that lipids (phospholipid bilayers) are polar!

The defining feature of lipids is- option. They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.

Lipid is a micro biomolecule that is made up of fatty acids or their derivatives. These are molecules that are soluble in nonpolar solvents and insoluble in water.

Thus, the correct answer would be the option. They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.

Answer:

DNA is the building blocks of every organism. It works as genetic or hereditary material.

Explanation:

Answer:

Hello! DNA (Deoxyribonucleic Acid) is a molecule composed of two polynucleotide chains, which coil around each other to form a double helix that carries genetic instructions for the development, functioning, reproduction and growth of all known organisms and many viruses. DNA and the instructions contained in it passes from adult organisms to their offspring during the process of reproduction. Hope this helps ! :)

lungs. that is why it is called respiratory system

Explanation:

Answer:

Mitochondrion.

Explanation:

The enzymatic reactions of cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria. Cellular respiration occurs in the double-membrane organelle called the mitochondrion. The folds in the inner membrane are called cristae.

Answer:

Cell wall: A protective layer covering the outside of the cell. They keep the shape of the plant cell, prevent water loss, and provide support.

golgi apparatus: Transports proteins and lipids around the cell. Often it is called the shipping department of the cell.

chloroplast: Chloroplasts store chlorophyll and this is where photosynthesis takes place in the cell.

Cell membrane: A layer that covers the cell, acts as a gate and determines what comes and goes through the cell. It allows good things in, while keeping others out.

Intermediate filaments: Provides support when when the plant cell comes into contact with other cells.

Ribosome: The part of the cell that is responsible for creating proteins.

Explanation:

The water is colder so you would burn more calories.

Far more calories are burned during cold water swimming than swimming in warmer water. The main idea behind this is a fact that cold water decreases the body temperature so much that the body must act to maintain temperature homeostasis.

Swimming is a preferred sports activity for burning of calories faster. It is because the resistance of water is so much higher and consistent than that of air, it becomes easier to burn calories by swimming than running. Swimming is a full body workout, that results in more calories burned.

When the temperature of water drops, the metabolism increases up to keep the body warm and people starts shiver, etc. Swimming in cold water will make the body work twice as hard to keep warm and burn more calories in the process. This is one reason why people lose more weight when swimming regularly in cold water than warmer water.
