1. Similarities:
they are both processes of cell division by which cells reproduce.
They share several steps of the process(prophase, metaphase, anaphase e telophase, cytokinesis) but meiosis has another division also with those same steps.
In both cases the cell duplicates its DNA by pulling it
apart into two sets, place the sets on each end of the cell, and then
divide down the middle.
Both produce new cells
based on their parent cells' genes.
2. The differences:
Mitosis:
- has 1 division per cycle
- one cell produces 2 new cells
- the genetic information in the mother-cell and the daughter-cells are the same. ( the number of chromosomes is also the same)
- it occurs in somatic cells
Meiosis:
- two divisions per cycle.
- one cell when divides produces 4 new cells
- the new cells have different genetic information. mixes the the genetic material from the
parent cells
- the number of chromosomes of the daughter cells is half of the mother's.
Those are both examples of ecological services!
The biceps and triceps muscles work together to allow you to bend and straighten your elbow. When you want to bend your elbow, your biceps muscle contracts (Figure below), and, at the same time, the triceps muscle relaxes. The biceps is the flexor, and the triceps is the extensor of your elbow joint.
The Krebs cycle can be used to make many various intermediates that can be siphoned off into other pathways. Mainly though, it makes the electron carriers NADH and FADH2 which can then be used in the electron transport chain to generate ATP.
It is called pili to transfer
