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.
Answer:
Eating a diet of low levels of protein could leave you to development a condition called edema, which causes swelling in your legs and feet from the buildup of fluids. Protein plays an essential role in maintaining salt and water inside your blood vessels and ensuring fluid does it make its way into the tissues. Hajima can cause stiffness, difficulty walking, increasingly painful swelling.
Explanation:
Answer:
(d). B-cells.
Explanation:
Adaptive immunity can be described as immunity which develops in response to exposure to a pathogen (or foreign molecule). throughout the life. It is divided into two types, humoral immunity and cell-mediated immunity.
Humoral immunity is mediated by B cells that secrete antibodies against particular antigens. These antibodies recognize and neutralize the antigens and activate cell-mediated immunity, which is mediated by T cells.
Thus, the correct answer is option (d).
Plant cells, but not animal cells
Animal cells, but not plant cells
Both plant cells and animal cells
Neither animal cells nor plant cells
Answer:
Both plant cells and animal cells
Explanation:
The process where the energy locked up in food is extracted take place in both plants and animal cells.This process is called Cellular respiration.It is the process of combining inhaled and diffused oxygen in the blood with assimilated food substances (glucose,amino acids,fatty acids and glycerol) to produce energy.
In both cells it takes place in the the cytoplasm and mitochondrial.
It begins with Glycolysis, followed by Krebs's Cycle..These two steps gives certain of ATPs to these cells
.However,the largest amount of ATPs is synthesized during oxidative phosphorylation for maximum of energy to be produced.This process involved the chemiosmosis where protons were diffused into the intramembranes by the proton pump (PMF) and diffused back into the matrix of the mitochondria to generate the electrochemical gradients.
The electrochemical gradients generate the energy for enzymes ATPase synthase needed for phosphorylation of ADP with Pi to give ATPs.
The oxygen act act the final electron acceptor.
