In which thyroxine help in growth and cellular metabolism and calcitonin helps to regulates calcium concentration in blood . If thyroid gland stops working then there is low level of calcium in our blood, which leads to mental and hormonal disorder.

If a drug that was an inhibitor of PP1 activity was ingested by a person
Reptile [31]

The correct answer is: Glycogen phosphorylase would remain phosphorylated and retain some activity.

Glycogen phosphorylase is directly involved in the regulation of glucose levels since it is a glucose sensor in liver cells: when glucose levels are low, phosphorylase is active and it has PP1 bound to it (phosphatase activity of PP1 is prevented). Therefore, there phosphorylase a will accelerate glycogen breakdown.

Which organelle is responsible for wilting?
makkiz [27]

Vacuole is the answer.

Wilting is the loss of rigidity of non woody parts of plants and occurs when turgor pressure falls. 

The vacuole controls turgor pressure. Turgor pressure dictates the rigidity of the cell and is associated with the difference between the osmotic pressure inside and outside the cell.

When a plant receives adequate amounts of water, the central vacuoles of its cells swell as the liquid collects within them creating a high level of turgor pressure which helps maintain the structural integrity of the plant along with the support of the cell wall.

In the absence of enough water , central vacuoles shrink and turgor pressure is reduced  compromising the plant's rigidity so that wilting takes place.
