A- uracil, test prep question
Answer: as the predator’s population goes up, the preys will go down, and as the prey’s goes up, the predators will go up. They are basically the opposite of each other.
Explanation: I can’t really tell what your question is. However if there are more prey to eat, then the number of predators will grow because they have more food. However, once there’s too many predators, the number of prey will drop which lowers the amount of food.
Answer: Hetrotypes are organisms (anything that lives) that can make it's own energy without absorbing it from other organisms. Example: Flowers, they get there energy from the sun, not from eating and absorbing other organisms.
Explanation:
The amino acid sequence of a protein which is referred to as its primary structure determines the structure or folding pattern of that protein
Mitosis is simply a stage in a cells life cycle, which could be broken down further into stages of mitosis. The rest (so not mitosis) is know as Interphase and is where the cell does its normal function, so if it's the cell is in a region of muscle it would contract/relax as normal etc.
Immediately before mitosis (or M phase) is what's know as G2 phase, where the G stands for growth and is where particular gene pathways are expressed to promote growth of the volume of DNA (chromosomes are duplicated, so from 46 to 92). At the end of this stage is a checking process where the DNA is scrutinised for any errors, if all is okay then the cell can proceed to mitosis, if not then the process is stopped so that errors in copying the DNA can be fixed. This is know as a restriction point and the cell must meet the requirements to pass. This is often seen as a way cells can prevent damage being replicated and therefore interfering with normal cell processes. When cells are cancerous they are able to override this and therefore divide and spread the damaged DNA.
