Answer:
Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.
These movements require no energy (in the form of ATP) on behalf of the cell.
Explanation:
The structures of prokaryotic and eukaryotic cells affects their function as prokaryotic cell has simpler structure that enables it to perform all the basic life processes but complex functions like multicellularity cannot be achieved by prokaryotes. Eukaryotic cells have complex structures and hence can perform several functions unlike the prokaryotes.
Prokaryotic cell is the primitive type of cell that do not posses a true nucleus. They also do not contain any cell organelles. The ribosome type present in prokaryotes is 70S.
Eukaryotic cell is the advanced cell that possesses a true nucleus and all the cell organelles like mitochondria, chloroplast, golgi body, etc. Eukaryotic cells can even form multicellular structures and perform sexual reproduction, unlike prokaryotic cell.

Jessica's symptoms of endometriosis can't be alleviated as its return could be experienced.
<h3>What is Endometriosis?</h3>
This is a disorder which occurs when tissue that is similar to the tissue that lines the uterus grows outside of it.
It is characterized by pain and menstrual irregularities symptoms and is usually managed through hormone therapy as the symptoms can't be permanently alleviated.

Tumor-suppresor genes inhibit cell division in the cell-cycle to repair DNA that is damaged or abnormal chromosomes to stop the mutation of such genes which causes pathology in the body.
Answer:
The correct answer is option - C.
Explanation:
Integral proteins are integrated proteins that are extended into the cytoplasm from the outer side of the cell. As it is known bilipid layer is fluid in nature it move around the cell layer.
These are the proteins also known as intrinsic proteins that contain parts with the side chains that are hydrophobic in nature. These are tightly located or packed between the hydrophobic amino acids and the membrane due to hydrophobic effects.
Thus, the correct answer is - option C.
