The answer is C. Pheromones are hormones (which are proteinous) produces by individuals of the same species and are a means to send communication signals for social interactions. They signal alarm, food and even sex. Sex pheromones are released by females beetles into the environment to signal their availability for mating. The pheromones are picked up by receptors on the male beetles and this is how they find the females.

A. Use a greater number of plants
Explanation:
The atmosphere is divided into different regions, called layers. The layer closest to the surface is known as troposphere, after which comes the stratosphere. The stratosphere begins at an altitude of 10 miles above the surface of the earth and stretches up to 31 miles above the surface of the earth. It is the second layer of the atmosphere (beginning from the surface of the earth) and it is the region which contains ozone, which plays a vital role in stopping ultraviolet radiation from reaching the earth's surface.
Answer:
The correct answer is D) dendrites; cell body; axon
Explanation:
Neurons cells makes the nervous system and are responsible for carrying the information from one body part to the other body parts. A neuron has three distinct parts dendrites and axon.
Dendrites are the neurons extension which receives the impulse and transfers to the cell body. We can link dendrite with our fingers. Cell body is a spherical part of neuron like our palm and it controls all functions of the cell. Then from cell body signals are transferred to axons.
Axon is a long part of the nerve cell like our hand which helps in transmitting the signals to the next neurons. Therefore the correct answer is D.
