Answer:
mitchondria is powerhouse
The correct answer is Oxygen.
The surface of the Earth was liquefied. As the Earth cooled, an atmosphere generated primarily from gases erupted from volcanoes. It constituted methane, hydrogen sulfide, and ten to 200 times as much as carbon dioxide in comparison to today's atmosphere.
It was considered that there was an extreme volcanic activity for the initial billion years of the existence of the Earth. The initial atmosphere was possibly majority carbon dioxide will no or little concentration of oxygen. There were slight quantities of ammonia, water vapor, and methane.
Answer:
1. Gibberellins
2. Abscisic acid
3. Cytokinins
4. Ethylene
5. Auxins
Explanation:
Hormones, generally, are chemicals produced in a specific part of an organism in order to bring about a physiological change in another part. Hormones produced by plants are classified into the following: Auxins, Gibberellins, Cytokinins, Ethylene, and Abscisic acid. They effect the following major functions in plants:
- Gibberellins: These are hormones produced by plants that stimulate stem elongation, seed germination, and flowering.
- Abscisic acid: These are hormones that regulates survival functions of a plant such as the opening and closing of stomata.
- Cytokinins: These are chemicals/hormones that helps plant cells divide.
- Ethylene: These are hormones that promotes ripening of fruit or blooming of flowers.
- Auxins: These are chemicals or hormones produced in plants that are characterized by their ability to induce cell elongation and cell division in stems.
Rtks can activate the enzyme phosphoinositide 3-kinase, which phosphorylates inositol phopholipids; these phospholipids then serves as docking sites that recruit specific intracellular signaling proteins to the plamsa membrane. RTKs may activate various pathways including; the MAP-kinae signalling module, the Ras signalling pathway, and the phospholipase C/inostol phospholipid signaling pathway.
The end result of cytokinesis is another cell cycle because it already is the final stage of a cell cycle.
