Evolution :).
Descent with modification helps to explain anatomical similarities among certain species. The bones of the forelimbs of humans, cats, and bats (you can add in penguins, alligators, and more) are used in different ways but have similar structures.
The best explanation is that these animals have a common ancestor. With new generations, new species emerged by natural selection from different populations, and with this, the bones become better for different tasks.
The forelimbs and other such structures with anatomical similarities due to a common ancestor are called homologous structures.
Active transport means the molecules move against a concentration gradient from areas of lower concentration to areas of higher concentration.
Answer:
Why is internal Fertilisation important to animals?
Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young.
Explanation:
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.
