Prokaryotic cells do not have a nucleus.
Solar thermal energy and solar electric energy because people like to conserve energy and help the earth so they use solar thermal energy. But people who are not enough nice to the earth they would use solar electric energy
The organelle malfunctioning in this case is lysosome. They have powerful enzymes and acids to digest and recycle cell material so they remove waste from the cell.
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:
Answer;
-Saturated fats
Explanation;
-Cholesterol is transported in the blood by different carriers. The relative amounts of cholesterol transported by each carrier can affect one’s risk for heart disease. The two major blood cholesterol carriers are LDL (low density lipoprotein) and HDL (high density lipoprotein).
-LDL cholesterol is known as “bad” blood cholesterol, and functions to deliver cholesterol to cells throughout the body and can be deposited as “plaque” on artery walls.
-Dietary fat, especially saturated and trans fats, may raise blood levels of total and LDL cholesterol. High total blood cholesterol levels and LDL cholesterol levels increase risk of heart disease.
