What is a concentration gradient? (Make sure to include the words: solute, solvent, and solution.)

Biology
1 answer:
prisoha [69]3 years ago
7 0

Answer:

Concentration gradient means difference in solute concentration among two regions of a solution.

Explanation:

When there is a difference in solute concentration in the two regions of a solution then the term concentration gradient is used .

      Various membrane transport process such as passive transport(diffusion and osmosis),facilitate transport depends on concentration gradient of solute molecule in both sides of plasma membrane.

      During passive and facilitate diffusion solute molecules are transported along their concentration gradient that means from high concentration region to the region of low concentration until equilibrium is being established.

Answer:

c. Beginning with the return from the systemic circulation, blood enters the <em>right atrium. </em>

a. Blood enters the right ventricle from the right atrium through the right atrioventricular valve which is also known as the <em>tricuspid valve</em>

d. The right ventricle contracts next, which forces blood up through the right semilunar valve which is otherwise known as the <em>pulmonary valve .</em>

e. After circulating through the <em>pulmonary capillaries</em>, the blood returns to the <em>left atrium. </em>

f. From the left atrium, blood moves through the left <em>atrioventricular valve </em>which is also referred to as the <em>bicuspid</em> or mitral valve.

b. From the left ventricle, the blood is pumped up to <em>aorta</em> the through the left semilunar valve which is sometimes referred to as the <em>aortic valve</em>.

Explain why you would sooner be hit by a ping pong ball vs a baseball. Use all the terms: force mass and acceleration!!
kati45 [8]

Answer:

Because the ping pong ball has a lesser mass than a baseball; hence the ping pong ball will accelerate faster than the baseball when a constant force is applied to both

Explanation:

The force applied to an object is a product of its mass and acceleration i.e. F=ma. According to Newton's second law of motion, the relationship between the mass of an object and its acceleration when force is applied to it was described.

In a summary, the second law states that that the acceleration of an object increases with increased force and decreases with increased mass. This means that the more the mass of an object, the greater the force needed to make it accelerate and also the more the mass, the lesser it accelerates.

In this case, a ping pong ball has a lesser mass compared to a baseball, hence, it will accelerate faster than the baseball assuming an equal force was applied. Since the ping pong ball will accelerate faster, it will hit a person faster than the baseball.

Assume that you touch poison sumac and still have not developed a rash 12 hours later. Can you safely assume you are not allergi
katrin2010 [14]
The first time you get poison sumac, it usually takes a while to show up. If you have had it before, it takes around a day or two if you have had it before, so I'd say the answer to the question is no.

A DNA mutation changes the shape of the extracellular domain of transmembrane receptor protein A produced by the cell. Which of
Tatiana [17]
<h2>a) is the correct option </h2>

Explanation:

The extracellular domain of the transmembrane receptor protein acts as binding site for primary messenger molecule whereas the transmembrane domain holds the receptor within membrane and the cytosolic domain has intrinsic tyrosine kinase activity, all these helps in proper cell signaling

If because of any mutation there is change in shape of the extracellular domain then that molecule that normally binds to the receptor protein will no longer attach hence cellular response will be deactivated
