Through suppression of the aconitase enzyme in the tricarboxylic acid cycle, aconitase, fluoroacetate is extremely hazardous to humans and other mammals.
'Lethal synthesis' of an isomer of fluor citrate is the cause. fluoroacetate is present in many different plant species, and ruminant animals can die from ingesting them consists of aconitase.
With the chemical formula FCH 2 CO 2 Na, sodium fluoroacetate is an organofluoride. The taste of this colorless salt, which is utilized as a metabolic toxin, is comparable to that of sodium chloride. Potassium and sodium salts are both derived from fluor acetic acid. In 1942, a report on the efficiency of sodium fluoroacetate as a rodenticide was published.

Answer:
frequency should be doubled
Answer : He needs to use a larger sample size to improve his experiment.
Explanation : As Johannes wants to know whether soil, water, or both are needed for plant growth. He chooses to conduct experiments on a willow tree for five years. To get the improvement in his experimental methods he can choose a larger size of the sample and test its results. As larger size will allow him to gauge accurately on the smaller factors and results will be more reliable. Larger sampling will ensure the homogeneity of the test sample, which will yield better and reliable results.
Answer:
Option (b) When dehydrated, a camel stores nitrogenous wastes in its tissues to conserve water.
Explanation:
The camel has good a hump on its back that helps with water storage. This is also made up of a water soluble fatty substance and fats. The water regulation is also controlled by the nephron which is an integral part of the kidney. The nephron has the Loop of Henle that regulates the retention of the water in the body. When there is no water, the potential of the ions force the water back into the kidneys so that the cells do not get disturbed. The nitrogenous wastes are expelled out as soon as possible because they form ammonium salts that may disturb the cell metabolism.
Hence, option (b) is not true.
