Answer:

If the membrane were fully permeable to all substances, then anything could enter the cell. This would upset the balance between the cell's contents and the outside environment. There is only so much ability to store substances and utilize substances, therefore, the cell would not be able to maintain homeostasis.Oct 17, 2010

adoni [48]

Answer:

The correct answer is: she won't have children with the disease because for this particular condition to appear, both parents need to have the trait and she doesn't have it.

Explanation:

Sickle Cell Disease is a condition that affects the red blood cells, since the hemoglobin (the protein inside the red blood cells that carry oxygen and carbon dioxide) is abnormal. This condition produces anemia and may lead to higher chances of bacterial infection and strokes.

Sickle Cell Disease is a genetic condition that is inherited in a recessive way: this means that for someone to have it, both parents must have the trait for the condition.

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.
