Explanation:
Answer;
B) four chromosomes
Explanation;
-Mitosis is a type of cell division that involves nuclear division in eukaryotic cells and occurs when a parent cell divides to produce two identical daughter cells.
-Mitotic cell division produces two daughter cells that are genetically identical to each other, and to the parental cell. Thus, a diploid cell, 2n, (contains two sets of chromosomes), yields two daughter cells that are also diploid.
-For example, in human beings, mitosis takes place in the somatic cells where a parent cell with 46 chromosomes produces two daughter cells each with 46 chromosomes.
Answer: They divide it on eons.
Explanation:
They can see it from geologic strata and the fossil record. Major volcanic events altering the Earth's environment and causing extinctions may have occurred 10 times in the past 3 billion years. Different eons have different animal and plant life. (eg. trilobites)
Hello,
Convection currents<span> in the mantle drive plate tectonics. Convection is the reason for o</span>cean currents. Ocean currents<span> result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement.
</span>
Both the mantle and ocean experience <span>the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock; this is called, again, convection.
