According to the article I've read in the website of Harvard Health Publishing (Harvard Medical School), the causes of overweight or obesity have been implicated by more than 400 different genes. Genes provide overweight in so many ways like metabolism, appetite, cravings, distribution of fats, and stress eating. Although it depends on one person to another person. Researchers have said that 25% of predisposition to be overweight is accounted to genes, while 70%-80% for genetic influences. These are just some of the reason how much of your weight depends on your genes:
-For much of your life, you have been overweight
-Overweight is seen on your parents or relatives, your likelihood to be developing obesity is as high as 80% if both of your parents are overweight
The correct option is this: TWO DRAGONFLY SPECIES REGULARLY MATE BUT THEIR GAMETES ARE INCOMPATIBLE.
In biology, there are different types of reproductive barriers, one of these is prezygotic barrier. A prezygotic barrier is a kind of mechanism that prevent reproduction from occurring by blocking fertilization. In this case, the concerned species will be mating together, but their gametes will not be compatible and thus, zygote will not be formed.
A postzygotic barrier on the other hand is said to occur when the reproduction process is blocked after the formation of zygote or after fertilization has taken place. A good example of this is an hybrid mule that is sterile and can not reproduce.
Chloroplasts are found in plant cells.chloroplasts absorb sunlight and when used with water and carbon dioxide to produce food for the plant (the food is mostly called sugar for the plants).
Answer:
Anaerobic heterotroph
Explanation:
E. histolytica It is an anaerobic parasite of the protozoan family. It's anaerobic because they can survive within the human being's organism in the absence of oxygen. It is heterotrophic because it feeds on digested food in the intestine of its guests. It also kills and degrades nearby cells to ingest nutrients.
This amoeba causes diarrhea. Amebic colitis is one of the leading causes of diarrhea in the world, especially in developing countries.
