Answer:brightly colored males
Explanation: for apex
The active site of an enzyme would form enzyme-substrate complex thus lowering the activation energy of the reaction and high rate of reaction is found.
Explanation:
The energy required to start the reaction is activation energy. In our system enzymes catalyses the reaction by lowering the activation energy. When the substrate binds to the active site or catalytic site of enzyme, an enzyme- substrate complex is formed. This complex reduces the time required for substrate changing into product. The enzyme substrate complex results in the conformational changes and contributes in lowering of activation energy.

Answer:
Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers.

Answer:
The ability of caffeine to inhibit adenosine receptors, plays a very important role in heightened alertness and sleeplessness.
Explanation:
"<em><u>Caffeine</u></em>" (<em>1,3,7-trimethylxanthine</em>) is an alkaloid obtained from plants. It has a chemical formula of C8H10N4O2.
Caffeine is generally <em>hydrophillic</em> but sufficiently <em>lipophilic</em> to pass through all biological membranes and readily cross the blood-brain barrier.
Therefore can bind with the adenosine receptors. Due to the blocking of adenosine inhibitory effects through its receptors held by paraxanthine and caffeine, it indirectly affects the release of <u>norepinephrine, dopamine, acetylcholine, serotonin, glutamate</u> e.t.c.
The release of the above-mentioned hormones have a great impact on the heightened alertness of the body, especially <em>dopamine</em> and <em>serotonin</em>.
