Answer:
It is important to classify the millions of species on Earth because it makes study of organisms easier. Classification occurs on the basis of similarities and differences that is present among the organisms. Organisms are placed in one group if they are similar in characteristics. For example, those organisms which are placed in animals have the ability to move from place to place and unable to make their own food.
Answer:
The charges inside and outside of the neuron before receiving a stimulus are negative and positive, respectively, which corresponds to the transmembrane rest potential.
Explanation:
Neuron is the specialized cell of the nervous system in charge of transmitting electrical impulses. The generation of a nerve impulse in the form of an electric current is due to a change in the transmembrane potential.
<u>Outside the neuron cell, electrical charges are predominantly positive, and the ion with the highest concentration is sodium. In the intracellular space, a great quantity of proteins provide negative charge, and there is a predominance of potassium ions</u>. Under these conditions, the ionic channels are closed.
For this reason, a neuron at rest, before receiving a stimulus, presents positive charges on the outside and negative charges on the inside, and the membrane potential in this condition is estimated at a value of -65 mV.
Once a stimulus is produced, the ionic channels open and Na+ ions enter the cytoplasm, exchanging them for K+, which implies a change in the membrane potential which, on reaching the threshold, produces an action potential and the nerve impulse is produced.
The growing or farming of marine plants or animals under controlled conditions is called aquaculture.
<h3>What is aquaculture?</h3>
Aquaculture is the farming of aquatic animals or plants, including breeding, raising and harvesting in different types of of water environments in controlled conditions.
Aquaculture includes the following:
- Mariculture - involves using seawater
- Fish Farming - the farming of fishes
- Algaculture: - involves the farming of algae.
In conclusion, the growing of marine organisms is called aquaculture.

ATP is the chemical substance that is used to power the cellular activities
The right answer is meditation.
Meditation is a very ancient spiritual, mental and postural practice. During meditation, the individual comes to an introspection and a long reflection on himself.
Meditation finds its origin in the East, but also in the Buddhist tradition. The practice of meditation allows you to control negative emotions and refocus your mind.
