Answer:
B. Cells in Alex’s body underwent mitosis to create new tissue
Explanation:
Mitosis is the cell division that forms two genetically identical daughter cells from one parent cell. It occurs in somatic cells and is responsible for the growth and development of individuals.
Alex gained the height as the cells in tissues of his body underwent the mitosis and produced new daughter cells. Repeated cycles of mitosis added a large number of new cells to his body to form new tissues in his body parts and caused an increase in his height.
When a cell is not dividing, the DNA is loosely spread throughout the nucleus in a threadlike form called chromatin.
''The movement of chloroplasts is due to the movement of cytoplasm in the living cells of bean plants'' is the correct statement.
The above statement is correct because chloroplast is an organelle which moves in the cell through the medium known as cytoplasm. Cytoplasm is a thick fluid that fills every type of cell and organelles are floating as well as suspended in this fluid.
All organelles such as the nucleus, endoplasmic reticulum, chloroplast and mitochondria etc are located in the cytoplasm. The portion of the cytoplasm except the organelles is called cytosol so we can conclude that chloroplast is an organelle which moves within the cell with the help of cytoplasm.

The given question is incomplete, the complete question is:
Grizzly bears are an integral part of the ecosystems in which they live and thrive. An example of their value to biodiversity includes their role in providing forests with a large amount of nitrogen needed to grow and persist through the consumption of salmon. This is an example of what type of species value?
Select one:
a. None of the above
b. Direct
c. Indirect
d. Cultural
Answer:
The correct answer is indirect value.
Explanation:
An illustration of the environmental service value is the production of a huge concentration of nitrogen within a locality. All the non-consumable values like economic values, social, cultural, aesthetic values, etc. come under the category of indirect values.
An indirect value indirectly helps an organism to thrive within a surrounding, like in the given case production of nitrogen is a non-consumable value, thus, it can also be considered as an indirect value. On the other hand, all the productive and consumable values in the form of medicine, food, etc come under the category of direct value.
