When one DNA molecule is copied to make two new DNA molecules, the resulting DNA molecules contain A) none of the parent DNA. B) 50% of the parent DNA. C) 75% of the parent DNA. D) 100% of the parent DNA

Answers

Answer 1

Answer:

50% of the parents DNA

A student made a model of a cell. First, she filled a clear plastic bag with gelatin.
Then, she added a rubber ball.
What are two limitations of the student's cell model?

A. The model is not as easy to see and hold as a real cell is.

B. The model does not show that cells can contain smaller structures inside
them.

C.The model does not show how a real cell gets the energy it needs to live.

D.The model is made up of materials that are different from those found in
real cells.

Answers

B) the model does not show that cells can contain smaller structures inside.

This is true because only a rubber ball was added, indicating that only a nucleus or any one organelle is present in a cell. However, the cell contains more than one organelle from the nucleus, mitochondria, Golgi apparatus, smooth and rough endoplasmic reticulum, ribosomes, and more.

Another possible answer would be D since they model does not show the process of cellular respiration where cells undergo this process to create ATP in the mitochondria.

What does oxygen poor blood deliver to the
lungs?
A. carbon dioxide
B. glucose
C. water
D. ATP

Answers

Answer:

A.carbon dioxide

Explanation:

oxygen poor blood means the blood is rich with Carbon dioxide

The oxygen poor blood delivers to the lungs carbon dioxide out of the body organs and cells. Thus, the correct option is A.

What is oxygen poor blood?

The heart is divided into two separate pumping systems, which include the right side and the left side. The right side of the heart receives oxygen-poor blood that is deoxygenated blood from the veins and pumps it to the lungs, where the blood picks up oxygen gas from the alveoli and gets rid of carbon dioxide gas.

Deoxygenated blood has less oxygen or it is oxygen-poor and contains is carbon dioxide rich. The right heart pumps this deoxygenated blood to the lungs where it picks up additional oxygen gas.

As the blood travels through body, oxygen gas is used up, and the blood becomes oxygen poor or carbon dioxide rich. Oxygen-poor blood returns from the body to the heart by the superior vena cava and the inferior vena cava, the two main veins which bring blood back to the heart.

Therefore, the correct option is A.

The cumulative work of many scientists can often be summarized as theories or laws. how is a theory different from a law

Answers

Answer:

A law is something in science that can be proved through experimenting. When the experiment is done properly, the same outcome will be achieved every time. A law does not attempt to explain why something is the way it is, it only states it.

A theory is an idea that has a large amount of scientific data backing it and is the accepted answer by most scientists, but there is no way to experiment on a scientific theory. A theory will never be able to become a law. A theory explains what it is describing.

A cell is the outer covering of the cell, which provides protection and rigidity to the cell. It is made up of lipid and triglyceride or cellulose. The cell wall is presenting many cells, like plant cells, fungi, and bacteria cells.

The cell wall is made up of different substances in different animals. Plant cells have a cell wall that surrounds their plasma membrane and offers tensile strength as well as defense against osmotic and mechanical stress. Additionally, it enables the development of turgor pressure or the pressure of the contents of the cell against the cell wall.
