Which of the following describes density?A. the amount of matter in a specific volume
B. all of the above.
C a measure of how tightly the particles in a substance are packed together
D. the mass of an object divided by its volume

Answers

Answer 1

Answer:

The statement that describes density is:

The mass of an object divided by its volume

What is density?

It is a scalar magnitude that allows us to measure the amount of mass in a certain volume of a substance.

Characteristics of density

It is an intrinsic property of matter, since it does not depend on the amount of substance considered.

It is usually expressed in kilograms per cubic meter (kg/m3) or grams per cubic centimeter (g/cm3).

Therefore, we can conclude that density refers to the relationship between the mass of a substance (or of a body) and its volume.

Answer 2

Answer:

Answer:

Explanation: Density is not the weight or matter it is the amount of particles that are packed into a set area. For example a dumbbell is more dense than styrofoam even though styrofoam may take up more space.

Peristaltic waves are ________.A. segmental regions of the gastrointestinal tract
B. churning movements of the gastrointestinal tract
C. pendular movements of the gastrointestinal tract
D. waves of muscular contractions that propel contents from one point to another

Answers

Answer:

Option (D).

Explanation:

Peristaltic movements are involuntary movement occur due to the longitudinal and circular muscle.Peristaltic waves helps in the passage of food from one point to another during the process of digestion.

Peristaltic waves occur mainly due to muscular contraction. These contractions propel the contents from one location to another. These waves occur in stomach, intestine and esophagus.

Thus, the correct answer is option (D).

Peristaltic waves are waves of muscular contractions that propel contents from one point to another. Therefore, the option is D.

The waves of muscular contractions known as peristaltic waves are responsible for moving materials from one location to another. They are in charge of the transportation of food through the digestive system from beginning to end.

Therefore, peristaltic waves are waves of muscular contractions that propel contents from one point to another

What is the function of the cell membrane?

Answers

The cell membrane has two functions and one is a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
