The answer is A. photoperiodism.

Photoperiodism is an organism reaction to the lengths of days and nights. Some plants require longer days, and some require shorter days. By changing the lengths of days and nights, commercial plant growers are able to increase plants productivity.

Tropism is plant growth in a response to a stimulus.
As it name suggests, <em>photo</em>tropism is plant growth in a response to light. 
<em>Gravi</em>tropism is plant growth in a response to gravity.
Thigmotropism is plant growth in a response to contact

Cross bridge formation between myosin heads and actin molecules is caused by the elevation of calcium ion concentration in the c
Naily [24]

Answer:

by the sarcoplasmic reticulum's calcium ion pumps

Explanation:

Rigor mortis or postmortem rigidity, is a state caused by chemical changes in the muscles that occur post mortem and  cause the limbs of the corpse to stiffen.

This occurs because after death, there is no cellular respiration and consequently, no oxygen nor ATP (ATP is required for the muscle relaxation).

Calcium enters the cytosol after death because it is released due to the deterioration of the sarcoplasmic reticulum and due to the breakdown of the sarcolemma. Ca2+ ions activate the formation of actin-myosin cross-bridging necessary for the contraction. Muscles are unable to relax, because myosin heads continue to bind with the active sites of actin and there is no ATP to destabilize the myosin-actin bond.

What adverse response is known to occur in people who drink copious amounts of water while participating in intense physical act
MArishka [77]
The correct answer is hyponatremia. This is also called water intoxication in athletes. Water is a substance that is devoid of any solutes and electrolytes. The major extracellular electrolyte sodium is present in the extracellular fluid and the plasma. In the event of increased water intake, the sodium in the plasma will be diluted hence will cause hyponatremia.
