Answer:
D.I, II, III, and IV
Explanation:
All living things are able to respond to stimuli in the external environment. For example, living things respond to changes in light, heat, sound, and chemical and mechanical contact.The organism responds to the stimuli by means of a number of effectors, such as muscles and glands.
As humans, we detect and respond to stimulus in order to survive. For example, if you walk outside on a very sunny day, your pupils will constrict to protect your eye from taking in too much light and being damaged. Your body reacts to the stimulus (the light) to protect you.
Insect responses to stimuli can simplify rearing. For example, the positive phototaxis of scale crawlers makes them easily collected.
Like all organisms, plants detect and respond to stimuli in their environment. Their main response is to change how they grow. Plant responses are controlled by hormones. Some plant responses are tropisms.
A research group has now discovered that bacteria not only respond to chemical signals, but also possess a sense of touch. The researchers demonstrate how bacteria recognize surfaces and respond to this mechanical stimulus within seconds. This mechanism is also used by pathogens to colonize and attack their host cells
Greek colonization greatly encouraged trade mostly because their colonies were mainly along the large Mediterranean body of water, which facilitates trade by boat.
