Answer:
The Chemical Coupling:
A coupling reaction in organic chemistry is a general term for a variety of reactions where two fragments are joined together with the aid of a metal catalyst.
The Conformational Coupling:
The basic idea, as originally proposed by Robin Irvine, is that stimulation of the IP3 receptor (IP3R) by store emptying induces a conformation change that is transferred to the channel in the plasma membrane through a direct protein-protein interaction (3)
The Chemiosmotic Coupling
For approximately twenty years, it has been generally agreed, in accordance with the chemiosmotic theory, that the coupling of electron transfer reactions to ATP synthesis is mediated by a proton electrochemical gradient, often alternatively called a protonmotive force, generated across these membranes by electron
Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes)
Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical.
Coral can be a good food source, which it is fished for people all over. But too much of it can be bad for coral reefs.
Using nets instead of bad fishing devices can lead to fish eating algae which is good for the ecosystem.
Traps that are too close to coral reefs can damage them, leading to death or a long time to recover.
Answer:
Though ice and snow are both made up of water, there is a difference between the two. Snow is nothing but the frozen atmospheric vapour which falls in winters on earth as light flakes whereas ice is simply frozen water.
