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.
The level of succession which involves a small snake is found eating a cricket in a grassland is a Secondary succession.
<h3>What is Secondary succession?</h3>
This is the type of succession which involves an area previously occupied by living things is disturbed or disrupted.
The grassland area has been occupied with living things already which makes it a secondary succession.

CAM plants keep stomata closed in the daytime, thus reducing loss of water. They can do this because they - fix 
into organic acids during the night.
The correct option is a.
As an adaptation to dry environments, certain plants developed a carbon fixation mechanism known as crassulacean acid metabolism, or CAM photosynthesis, which enables a plant to photosynthesize during the day but only exchange gases at night.
During the day, the malate is transferred to chloroplasts where it is transformed back to 
, which is then utilised during photosynthesis. At night, the is stored as the four-carbon acid malic acid in vacuoles. The enzyme RuBisCO is surrounded by a concentration of pre-collected , which improves photosynthetic efficiency. Plants in the Crassulaceae family were the ones that initially revealed this process of acid metabolism.

Answer:
Lactic Acid
Explanation:
Lactic acid builds up during strenuous movement combined with lack of sufficient oxygen.
Kinetic energy is energy which a body possesses by virtue of being in motion and it relates to diffusion and the temperature of a substance is related to the average kinetic energy of the particles of that substance. It relates to diffusion because each collision aids in the diffusion of a substance within a gas or liquid. Yw , mark me brainlist please :)
