Mitochondria is the powerhouse of a cell.
Answer:
The most important feature that permits a gene to act as a molecular clock is having a reliable average rate of mutation.
Explanation:
The molecular clock is also known as the “evolutionary clock” or “gene clock”. These was studied by scientists suchs as Darwin, and it made possible for paleontologists to study humanity evolution. <em>Through this idea we talk about the biological concept of heredity: we inherit information in the form of genetic molecules (usually DNA) from the previous generation</em>. This is possible thanks to Mutation. In mutation, DNA and protein sequences evolve DNA and protein sequences evolve over time and among different organism.
Answer:
Metabolism is the process by which your body converts what you eat and drink into energy. During this complex biochemical process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.There are three basic metabolism types: ectomorph, mesomorph, and endomorph – definitely words you probably don't use in your normal, day-to-day conversations.If your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.
Answer:
The nucleus is like the principal of a school, the cell membrane is like a school building, and the mitochondria is like the staff in a school.
Explanation:
Definitions:
- The nucleus of a cell contains the majority of the cell's genetic material, and coordinates cell activities like protein synthesis and cell division.
- The cell membrane is the semipermeable membrane of a cell that surrounds the cytoplasm (the material inside the cell other than the nucleus).
- The mitochondria is "the powerhouse of the cell", because it produces most of the chemical energy needed to power the cell's chemical reactions.
The nucleus is like the principal of a school: the nucleus controls the cell, much like how the principal controls the school.
The cell membrane is like a school building: the cell membrane forms a boundary between the cell and outside environment, much like how the school building separates you from outside.
The mitochondria is like the staff in a school: the mitochondria powers the cell, much like how the staff in a school keep the school running.
