<span>D. Temperature and pH can affect how enzymes work.</span> The action of enzymes can be affected by many factors including temperature, pH and ionic strength. Optimum pH differs per enzyme. Enzymes can be destroyed by heat more than the allowed optimum temperature.
They are not something that you prevent from being made in your body. They are automatically made when you eat food that is not automatically converted into calories. This is used for energy later on for you body.
But too much of triglycerides is bad for you. This condition is called hypertriglyceridemia. Your doctor can detect if you have this condition by simply running a lipid panel (a blood test) that measures your overall cholesterol, you LDL and HDL cholesterol, and also measuring your triglycerides.
If you do take this test, they will make you fast for about 8 hours. They make you do this because triglycerides are usually lowest after you fast but goes up really high after a big meal (like a Thanksgiving Dinner!).
(Extra: your triglycerides are measured in milligrams per deciliter (mg/dL) and if your levels are:
BELOW 150 -----------------Healthy
150-199 -----------------------Borderline
200-499 ---------------------High
500+ --------------------------Very High
Most people are under 200, so in the end, you don't have to worry about your triglyceride levels.

Answer:
The meaningful differences between organisms in a population are genetic. Variations in the genome of members of a population arise through mutation. Occasionally, a mutation occurs in an individual that is beneficial, that helps that organism be better able to survive and repoduce in its current environment.
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger and as volume increases, surface area to volume ratio decreases. The larger a cell, the less easily it can get rid of waste and it also has more trouble getting water, nutrients and gases in. That is why we do not see giant cells. Instead we see multiple cells in larger organisms.
One way to increase surface area is to flatten the cell. That is why red blood cells are flat discs, instead of spheres. Another way is elongation. That is why many bacteria are rod shaped, and why neurons are elongated. In fact, the human body relies on the same principle to adapt to climate. Long tall and lean folks with long arms and legs live in East Africa, because such shapes increase surface area to get rid of excess body heat to avoid heat strokes. Europeans and Asians adapted to cold climates, in contrast, have shorter arms and legs and rounder torsos to minimize surface area. to conserve body heat.
