1. hydrosphere: the system that contains all forms of water; liquid, solid and gas
2. biosphere: the sphere that contains all living things
3. atmosphere: the system that contains the gaseous layer of a planet
4. cryosphere: the system that contain the frozen ice portion of a planet
5. lithosphere: the system that contains the solid rocky crustal portion
The simple answer is, ALWAYS have an evacuation plan.
If in an earthquake stay away from cabinets, climb under a table or chair, and do the right sitting position (Hold on to your neck position.)
Hope I helped, would love if you left me a thanks! Thanks :)
Answer: Chemical energy
Explanation: During light dependent reactions of photosynthesis, light is absorbed by chlorophyll and other light absorbing pigments. The light energy absorbed is conserved as ATP and NADPH. In light dependent reactions, the light energy is used to split water molecules into hydrogen ions and oxygen molecules and consequent production of ATP and NADPH. This reaction is called photolysis of water. The oxygen molecules is evolved while the hydrogen ions are transferred to NADP+ to produce NADPH. In light dependent reactions, ATP and NADPH are produced.
ATP and NADPH are forms of chemical energy which are usable in the cells. Therefore, light energy is converted into chemical energy in light dependent reactions of photosynthesis.
During inter-phase of cell division, the genetic material is duplicated to allow for division into 2 identical daughter cells. The tumour suppressor gene checks for errors in the DNA, and if found, apoptosis (cell death) is initiated by p53 protein. The pRb (retinoblastoma) protein stops the progression of the cell cycle form G0 into S phase if the cell division is complete hence stemming unregulated cell division.
