Answer:
K+
Explanation:
Leak channels are the gated channels that randomly open and close. The plasma membranes have many more potassium ion (K+) leak channels than the leak channels for other ions such as sodium ion. Also, the potassium ion leak channels are leakier than the sodium leak channels and allow exit of more and more K+ from the neurons. This makes the inside the neuron negative at rest and outside becomes more positive. In this way, the leakage of K+ across the K+ leak channels is mainly responsible for maintaining the resting potential.
Answer:
<h2>A</h2>
Explanation:
Pepsinogen is an inactive enzyme which is activated into active digestive enzyme known as pepsin. It is a digestive enzyme which causes breakdown of proteins. Active pepsin causes cleavage of more pepsinogen molecule by a positive feedback loop and leads to increase in the concentration of active pepsin molecule.
Its concentration increases according the requirement in the body which is controlled by feedback system.

Many Archaea are specialized to live in extreme environments. Just three types are described here. <u>Archaea are now known to live just about everywhere on Earth.</u> They are particularly numerous in the ocean.
Answer:
<u><em>BRIEF EXPLANATION</em></u>
Photosynthesis is the anabolic process of building up glucose and making O2 from CO2 and water while cellular respiration is the opposite catabolic process of breaking down glucose by oxidizing it with O2 to get CO2 and water.
Explanation:
<em><u>MAIN ANSWER TO THE QUESTION.</u></em>
Photosynthesis is like when you’re trying to gain muscle and you eat tuna and eggs to turn it into muscle tissue. This takes energy in the form of food just like how photosynthesis requires sunlight for energy.
Cellular respiration is like when impoverished people starve for a week because they don’t have sufficient food to eat for nutrients. They have to get them from somewhere else. So the body breaks down glycogen, body fat and muscle tissue to provide the energy.
