Answer:
(B) Energy transfer between trophic levels is almost always less than 20% efficient.
Explanation:
The ultimate source of energy on the Earth is the Sun. The energy coming from the Sun is captured by green plants by the photosynthesis. During photosynthesis sun energy is fixed into chemical energy (carbohydrate). So, in an ecosystem energy flow is unidirectional (from sun to the green plants). The fixed chemical energy from green plants is transferred to the herbivores then to carnivores through food. When one organism eats another organisms, only 10 % of the energy present in the organism is transferred as a food for the next organism and a large amount of energy is lost as heat into the environment. Thus, energy keeps on decreasing when stored energy moves from producers to top consumers. Thus, less than 20% energy transfer limits the trophic levels in most of the ecosystem.
Answer and Explanation:
If the endolymph is mixed with the perilymph then their potassium levels will tend to reach to equilibrium as it is stated that the intermediate membrane have been ruptured. The potassium level will decrease here.
In stereocilia the concentration of the potassium will also tend to reach equilibrium because the membrane is ruptured and the flow of the ions will not remain unidirectional.
The calcium concentration is more in the perilymph as compared to endolymph so the rupturing will allow more calcium ions to get incorporated in the hair vesicles.
The hearing will be affected by mixing of endolymph and perilymph as it will disturb the concentration of various ions and hence the ion channel will be clogged and there will be hearing loss.
The plastic handle, as long as it's heat resistant, because the metal handle would absorb the heat and make it extremely hot to the touch and could potentially burn your hand while you use it.
Answer:
The correct answer would be -provide detailed information about the research and drug and let the man decide if he wanted to withdraw from the research or take new drug.
Explanation:
In this type of case where there is a drug that is in on going study or in clinic trail which is showing promising result, investigator should provide the client or subject a comprehensive account of the drug with is pro and cons and side effects.
He should discuss about the both currently available drug in market and ongoing research drug and let the man decide whether he want to be part of the research or withdraw from the research.
