In active transport particles move by making use of energy in the form of ATP.

Explanation:

Unlike in passive transport particles have to move against the concentration gradient in active transport. Thus particles require energy to do so and this energy is in the form of ATP. Osmosis and simple diffusion are examples of passive transport where substances move from a region of high concentration to a region of low concentration.

This movement is down the concentration gradient. In active transport particles move from a region of low concentration to a region of high concentration which is against the concentration gradient. Active transport is of two types.

In the first type called primary active transport energy is directly used in the form of ATP. In the second type called secondary active transport an electrochemical gradient created by ATP is used to facilitate the transport.

Answer:

systematics is the correct answer.

Explanation:

The modern approach to classification, with the broader goal of reconstructing the evolutionary history, or phylogeny, of organisms is: systematics.

Systematics plays an important role in the field of biology.

Carl Linnæus is the father of Systematics.

Systematics refers to the study of the diversification,nomenclature, and classification of the living organism in the past and also in present.

Systematics is used to understand the evolutionary relationship and the purpose of systematics is to describe and explain biological variety.
The main objective of systematics is to identify species and to give scientific names to organisms, it used to determine the arrangement of the living organism and to study the evolutionary history of organisms.

Gemiola [76]

The answer is D. Species A will have fewer phenotypes.
Alleles are alternative forms of a gene. In species A, the leaf color is controlled by two alleles, for example, P and Q. They will have three possible genotypes - PP, PQ, and QQ. Three different genotypes give maximum three phenotypes.In species B, leaf color is controlled by three alleles, for example, L, M, and N. They will have six different genotypes - LL, LM, LN, MM, MN, and NN. Six different genotypes give maximum 6 phenotypes.

vladimir1956 [14]

Answer:

1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. Action potential.

2. neurons that detect chemicals such as those found in food. Chemoreceptors.

3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. Compound eyes.

4. the structure that gives the response to an environmental change. Effector

5. neurons that detect electrical fields. Electroreceptors.

6. secretion of hormones into the blood stream to affect distant processes. Endocrine.

Explanation:

An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.

There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.

Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.

The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.

There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.
