Answer:
Hypotonic solutions are those with less solute (again read as higher water potential). Isotonic solutions have equal (iso-) concentrations of substances. Water potentials are thus equal, although there will still be equal amounts of water movement in and out of the cell, the net flow is zero.

Explanation
If insulin cannot bind to the insulin receptor, then GSK3 will not be inhibited, nor will it be able to inhibit glycogen synthase as the activity of kinases such as PKB and GSK3 are dependent on the signal sent out as the response of binding insulin to the receptor. No binding leads to no signal which leads to no activity.
Answer:
B
Explanation:
Methane is one of the green house gases, and a very powerful one. It is even more potent at influencing global temperature than the most famous green house gases, CO2. Methane's chemical structure is in a way that gives it the ability to trap heat.
This means that an increased release of methane gas into the atmosphere, which is mostly done when cattles defeacates or passes gas, can drastically influence the warming on Earth.
