How many strands do DNA molecules have

Answers

Answer 1

Answer:

Two strands

Explanation:

So each DNA molecule is made up of two strands, and there are four nucleotides present in DNA: A, C, T, and G. And each of the nucleotides on one side of the strand pairs with a specific nucleotide on the other side of the strand, and this makes up the double helix. I hope this helps.

2.) Which of the choices below is a small organelle, made of RNA and protein; as well as a site of protein synthesis?

- vacuoles

- ribosomes

- Golgi bodies

- chloroplasts

Answers

Answer:1) Chloroplast, mitochondrion and vacuole are the organelles

Explanation:  a leaf is a organ of a plant and is not found in cells. An enzyme creates chemical reactions in the body. the DNA is just the plan on how to build the cell and how to do certain cellular processes. therefore a chloroplast, mitochondria and vacuole are all organells. also the mitochondrion creates energy, a vacuole stores food and water and a chloroplast converts the suns energy into food

Explanation:

Phosphorylation is an example of a post-translational modification of a protein. These modifications are covalently attached to the protein and can have significant effects on its function.

These affects include altering its activity, its binding to other proteins, and where it is found in the cell.

However, post-translational modifications do not affect the amino acid sequence of the protein.

Answer:

1: The higher the force applied to the ball, the harder to make a home run because of the third law: every action has a reaction, the reaction is absorbed by the bat.

2:Same equation: F=MA from the second law, if the ball has a higher mass, it will have a higher force.

Explanation:

The third rule, which states that every action has a response, which is absorbed by the bat, makes it tougher to hit a home run the more power is given to the ball.

Explain Newton's law.

Newton's laws of motion are three fundamental physical laws that describe the behavior of objects in motion and how they interact with forces. The laws were first published by Sir Isaac Newton in 1687.

Law of Force and Acceleration - The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. This law is often expressed as F=ma, where F is the net force acting on an object, m is the mass of the object, and a is the acceleration of the object.

Law of Action and Reaction - For every action, there is an equal and opposite reaction. This law states that when one object exerts a force on another object, the second object exerts an equal and opposite force on the first object.

(06.02 MC) Which of the following correctly explains the role of antibiotics in the human body? (2 points) a They break down damaging toxins created by bacteria. b They increase the number of white blood cells in the blood. c They rupture the cell wall or prevent protein synthesis in bacteria. d They reduce the effects of fever, swelling, and inflammation in the body.

Answers

Answer:

The beneficial role of antibiotics in the human body is given because they produce rupture the cell wall or prevent protein synthesis in bacteria.

Explanation:

Antibiotics are a group of drugs that fight bacteria, eliminating them, to cure infectious diseases.

The mechanisms of action of antibiotics aim to break the bacterial protection or interfere with their vital functions to make them unviable:

Destruction of the bacterial wall or membrane. Interference with protein synthesis. Inhibition of the synthesis of nucleic acids.

In general, the effects of antibiotics on bacteria are to rupture the cell wall or prevent protein synthesis. Through these mechanisms, antibiotics eliminate and prevent the reproduction of pathogenic bacteria, thus eliminating the infections they produce.

The other options are not correct because:

    a. Breaking down damaging toxins created by bacteria is an anti-toxin function.

    b. Antibiotics do not increase the number of white blood cells in the blood.

    d. Reduction of the effects of fever, swelling, and inflammation in the body is a function of antipyretics and anti-inflammatories.

Answer:

They rupture the cell wall or prevent protein synthesis in bacteria.

According to the model represented in the diagram, which of the following would cause the cell to not express the lacZ, lacY, and lacA sequences?


Binding the RNA polymerase to the gene

Preventing the repressor from binding to the lac operon

Removing the inducer

Transcribing the lacl sequence

Answers

Answer:

Transcribing the lacl sequence

Explanation:

lacZ, lacY, and lacA sequences are the structural genes, which needs to be expressed in order to produce their proteinous enzymes required for the breaking down of lactose sugar. The transcription of these three genes must occur with the aid of RNA polymerase binding to them.

However, a gene sequence called lacI encodes information for an repressor, which when expressed can inhibit the expression of the genes lacZ, lacY, and lacA. Hence, the TRANSCRIPTION OF THE LACL SEQUENCE cause the cell to not express the lacZ, lacY, and lacA sequences.

Answer: removing the inducer

Explanation: all sequences need an inducer present in order for them to be expressed

What would happen to an animal cell with an internal salt concentration of 10% if it were placed in a salt solution with a concentration of 30%?

O The water would move out of the cell and the cell would decrease in size.

O The water would move into the cell and the cell would increase in size.

O The salt would move into the cell and the cell would increase in size.

O The salt would move out of the cell and the cell would decrease in size..​

Answers

Answer:

The water would move out of the cell and the cell would decrease in size.

Explanation:

This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.

In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size

The time it takes for an animal to metabolize a drug to a non-detectable levels could be ____ than that of the withdrawal period 

A:Longer
B:Shorter
C:Same time

Answers

A:Longer
The physical effects of a drug wear off faster then your body metabolizes it to be un-detectable

The time it takes for an animal to metabolize a drug to a non-detectable levels could belongerthan that of the withdrawal period. Hence the correct option is A.

The metabolism of a drug refers to the process by which the body breaks down and eliminates the drug from the system. The withdrawal period is the time required after administering a drug during which the animal must not be slaughtered for human consumption to ensure that no residues of the drug are present in the edible tissues.

There are several factors that can influence the metabolism of a drug in animals, such as the drug's chemical properties, the animal's species, age, health status, and metabolic rate. Some drugs may be metabolized relatively quickly, while others may take longer to be completely eliminated from the system.

Hence the correct option is A.
