Answer:
Mitosis it's the Anaphase
when the spindle fibres contract, each chromosome splits at the centromere, and its two chromatids are pulled apart towards opposite ends of the cell. Each chromatids is actually a single stranded chromosome, since DNA replication took place
The transmission of heat requiring the movement of a liquid or a gas is Convection.
Convection: the heat transfer due to bulk movement of molecules.
Hope this helped :)
Have a great day
Answer:
This is because must of the cell must be in INTERPHASE.
Explanation:
The onion root tip is the growing part of the onion and many cells in it undergo mitosis. In the lab, it is prepared in a way that the cells become flat on the microscope slide so that you can observed them well.
In the cell cycle, most of the onions root tip cells are in interphase, they spend most of their life in interphase. In interphase, there is no observable changes in the celks, the cells keep on growing and the nucleus is been duplicated. This is because most of the onion root cells spend most of their time reproducing and growing in the interphase stage. During the interphase, the cells can still be seen in dark spots because the nucleus is still present and prophase has not started yet.
Answer:
It is an increase in available food amount.
Explanation:
An increase in predators would result in the prey species dying off. A decrease in habitat size would result in the species not having a place to live or hide from predators. A decrease in amount of available water would make the species die of dehydration.
An isotonic solution is when two solutions, separated by a semipermeable membrane, have equal concentrations of solutes and water. Imagine you're at a party and there are an equal number of guests in the living room and in the kitchen. It doesn't make much of a difference where you stand because you are equally as comfortable in either room. You have just as much space, you can move just as easily, and you have equal access to food. You don't spend a lot of energy trying to get out of one room or into another. This party is like an isotonic solution; everything is equal from room to room.
