Calculate the volume of a cylinder with a length of 20cm, and whose circular end has a radius of 2.5cm. First, work out the area of one of the circular ends of the cylinder. The area of a circle is πr2 (π × radius × radius). π (pi) is approximately 3.14.

Temka [501]

There are three main regions of the kidney.
1.Renal cortex - It is the outer region of the kidney which contains the renal corpuscles and the renal tubules (without the loop of Henle). It produces the erythropoietin.
2.Renal medulla - It is the innermost part of the kidney which contains the renal pyramids.
3.Renal pelvis - It is the region that collects urine from the nephrons, thus it contains the place where ureter leaves the kidney.

faltersainse [42]

The thorax is a very vital and important organ in the human body.

It is a structure that serves as a protective covering for organs in the body such as the lungs, the heart, some vital blood vessels e.t.c

It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

When a person breathes in, the chest cavity expands (the volume increases) and the pressure in the thorax decreases.

When a person breathes out, the chest cavity decreases in size, and the pressure in the thorax increases.

Therefore, we can see that the process of breathing in humans, follows the principle of Boyle's Law.

Boyle's law states that as the volume increases there is a decrease in pressure and as the volume decrease there is an increase in pressure.

Therefore, It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

Ne4ueva [31]

Answer: Hypertonic Environment

Explanation:

The salt solution and sugar solution is used for the process of food preservation as the bacteria and microorganism are not able to grow in such conditions that is being created by the solution.

The amount of the solute is more and the solution is less concentrated. The bacteria cell has less solutes and more solvent.

As per osmosis the water from the salt or sugar solution moves out from bacterial cell shrinks and dies.

This is how the bacterial cell dies and the food is prevented from spoilage.

The paper clip, which is denser than water, floats on the surface because of water's surface tension. Surface tension is a prope

sineoko [7]

The answer is cohesion. The high surface tension helps the paper clip (with much higher density) float on water. The property of a liquid that allows it to resist an external force, due to cohesive nature of its molecules. Cohesion refers to the attraction of molecules for molecules of the same kind. Water molecules have strong cohesive forces due to their ability to form hydrogen bond with each other.
