Answer:
is this Spanish or no i don't know
Nitrogen is important to life because it is a key part of amino and nucleic acids. Also, it is an important part of ATP, which is the basic energy molecule for living things. Neither plants or animals can obtain nitrogen directly from the atmosphere. Instead, they depend on a process known as nitrogen fixation.
The principal function of thyroxine is to stimulate the consumption of oxygen and thus the metabolism of all cells and tissues.
Thyroxine is termed T4. It travels through the blood to the target cells and becomes converted to triiodothyronine or T3.
T3 is the active form of thyroxine. T3 enters the target cell's nucleus binding to genes responsible or involved in the metabolism of sugar in the body. T3 stimulates these genes and in so doing metabolism (conversion of oxygen and calories to energy) is carried out by the cell, which also results in generation of body heat.
1. Mitosis is for growth and repair
Meiosis is for reproduction
2. Mitosis steps in order: interphase, prophase, metaphase, anaphase, telophase
Meiosis steps in order: interphase
Prophase 1, metaphase 1, anaphase 1, telophase 1, prophase 2, metaphase 2, anaphase 2, telophase 2
3. •The steps of mitosis and phase 1 of meiosis are similar
•Cells undergo Cytokinesis (they divide)
• DNA and chromosomes play a vital role in both
4. •mitosis results in 2 cells and meiosis results in 4 cells
• the daughter cells created by mitosis and identical to the parent cell, the gamete cells that are created by meiosis are not identical to original cell
• Crossing over of the chromosomes happens in meiosis but not in mitosis
