DNA is copied during replication.
There are four types of sensory receptors that respond to one of the four primary stimuli.
Thermoreceptors detect temperature changes in the environment.
Mechanoreceptors detect changes in pressure
Photoreceptors detect the photons composing light
Chemoreceptors detect chemical stimuli and are found inside the body (for example blood vessels). They are also responsible for our sense of taste and smell.
Thus, the correct answer to the question is D. on the tongue and in the nose, to detect taste or odor.
Answer: isotopes is the answer to this question
An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.
