Genes, otherwise known as DNA is located inside of a cell nucleus. And... theres no telling where it comes from.
Both a b c are the right answer choice for this question
Answer:
d They usually have certain special functions
Explanation:
a) They can all turn into the same kind of cell needed - this is false. Cells in a multi cell organism such as humans cannot turn to any type of cell, this functionality is called pluripotency, and only exists in specialised cells called stem cells. These cells are present early in development, and in some tissues where cells are replaced frequently, like the cells of the gut.
b) They are all identical - this is false. Although they all carry the same genetic information, the cells in a multicell organism are usually very different, carrying out different functions. E.g. the cells of the skin are very different from the cells of the blood.
c) They are prokaryotic cells - this is false. All prokaryotic cells are single celled organisms, only eukaryotic cells can form part of multi cell organisms
d) They usually have certain special functions - this is true. Cells in a multicell organism usually perform different functions in order to contribute to the entire organism. For example, the function of the cells in the heart is very different from the function of the cells in the brain.
Succession is important because it leads to mature and stable communities. The purpose of succession is for an ecosystem to reach balance state right after it is formed or after it is disturbed by man or some disasters. It will increase biodiversity and help to prevent the desertification.
