What would happen in an ecosystem without herbivores? A. The populations of secondary consumers would decrease.. . B. The popula
lions [1.4K]
I believe the correct response is A. The population of secondary consumers would decrease, as now these organisms can't obtain energy through the food they consume which is the primary consumers as there is none and thus the population in higher tropic level dependent on them would decrease. This is the secondary consumer.

What is energy coupling?
vagabundo [1.1K]

Answer:

c: the use of energy released from an exergonic reaction to drive an endergonic reaction.

Explanation:

<em>Energy coupling is a process involving two reactions whereby one of the reactions generate energy, and the generated energy is used to drive the other reaction. </em>

A reaction during which energy is generated is referred to as exergonic reaction while one in which energy is consumed is known as endergonic reaction. Hence, energy coupling can also be viewed as a process linking exergonic and endergonic reactions whereby the energy released in the former is used up by the latter.

A good example is illustrated by the light dependent and light independent reactions of photosynthesis during which the ATP and NADPH produced during the light dependent reaction is used to fix carbon dioxide in the light independent reaction.

<em>The correct answer is C.</em>

Why is ld50 data so useful in dealing with human health and environmental toxins?
alex41 [277]
LD50 or TD50: it is the Lethal Dose 50 (to refer to animals), and Toxic Dose 50 (to refer to the human being). To refer to animals is: the dose of a drug, a drug (generally a substance) that kills 50% of a population. To refer to the human being: it is the dose of a drug, a medicine (in general a substance) that produces toxicity to 50% of a population.<span>

<span>Find the LD50, it is very important to determine the dose in which the drug produces toxic effects and thus be able to approach or deduce the effective dose, that in cases of administering a new drug to the human being, it is necessary to find the effective dose 50 (Dose of the drug that produces a therapeutic effect to 50% of the population) in order to determine the Therapeutic Margin or Therapeutic Index.</span></span>
