Answer:D
Explanation: The answer is D because Archaebacteria are the only bacteria that defy the laws of nature and live in harsh/ tough environments.
A bacterium called Vibrio cholerae causes cholera infection. The deadly effects of the disease are the result of a toxin the bacteria produces in the small intestine. The toxin causes the body to secrete enormous amounts of water, leading to diarrhea and a rapid loss of fluids and salts (electrolytes).
Answer:
The more strongly the ORN is activated, the fluorescence decreases.
Explanation:
Olfactory receptors are commonly known as olfactory ordants receptors that are located on the cell membrane of olfactory receptor nerves. They are mainly used for the detection of different types of smell.
Olfactory receptor response is used t measure the functioning of the olfactory receptor. The fluorescence element labelled with calcium used in this type of fluorescence. The activation of ORN can be measured by the fluorescence activity. The decrease in fluorescence is associated with the increase in the activation of ORN.
Thus, the correct answer is option (b).
Im pretty sure it is C because all living things consist of at least one or more cells
