Answer:
The correct answer is - option B. 19 mg/kg soil.
Explanation:
Phytoremediation is a process of the bioremediation that uses different plants to transfer, remove or destroy the contaminants from the soil. Cd is one of the contaminants that are removed or destroyed by the process of the phytoremediation.19 mg/kg soil is the concentration was available in the soil prior to the phytoremedaition took place.
Thus, the correct answer is - option B.
The best answer is (3).
Guard cells help regulate water loss by controlling the opening and closing of stomata which facilitates gas exchange and transpiration in plants.
Guard cells are able to control the opening and closing of stomata by changing shape. The guard cells take in potassium ions which causes water to diffuse into them by osmosis. The cells then swell and become bowed. When this happens, they bend way from each other thereby opening the stomata.
When they lose the potassium ions, water diffuses out by osmosis and the cells become flaccid and less bowed thus closing the stomata between them.
You can rub a permanent magnet against something else that can be magnetized, like a paper clip.
For every one NADH molecule oxidized at complex I, 10 HYDROGEN IONS are pumped across all of the complexes from the mitochondrial matrix to the inner membrane space
Cellular respiration has three main stages: glycolysis, the Krebs cycle, and oxidative phosphorylation.
<h3>
What is Oxidative phosphorylation ?</h3>
During oxidative phosphorylation, the reduced form of nicotinamide adenine dinucleotide (NADH) helps to carry electrons from one reaction to another across a series of molecular complexes.
- The electron transport chain of oxidative phosphorylation is coupled to the generation of an electrochemical proton (H+) gradient across the mitochondrial inner membrane.
- Subsequently, this proton H+ gradient is then used to produce ATP by an ATP synthetase.
