Answer:

1. Explain why predators need to eat more than primary consumers.  

Explanation:

Predators need to eat more than primary consumers because in the trophic pyramid, primary consumers are at the bottom which means they receive the most energy because they eat the plants. As the pyramid goes on upwards, energy is lost each time, so that means by the time it reaches the top of the pyramid their is only about 0.1% of the energy we started with when the primary consumers ate the producers. Meaning, the predators need to eat more than the primary consumers because although the predators eat more than the primary consumers, they still at the end of the day get the same amount of energy just one eats more than another.

Which statement describes a similarity between meiosis and mitosis
VLD [36.1K]

Mitosis produces 2 daughter cells which are genetically identical to the parent cell. Each daughter cell is diploid. A diploid means containing the normal amount of chromosomes. This is the result of DNA replication and 1 cell division. ... Meiosis is used to produce gametes which are sperm and egg cells, the cells of sexual reproduction.

They are similar because crossing over happens in both.

What has to happen before mitosis begins?
Leokris [45]

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.
