2. when your sibling jumps out from hiding and scares you, you jump back and gasp. which characteristic of life is best represented? growth reproduction evolution response to stimuli

The characteristic of life that is best represented in the above example is the response to stimuli.

Control and coordination in the body is brought about by the nervous system and the endocrine system of the body. Nervous system is involved in the production of the reflex action during such situations. Stimulus is the event that evokes a specific area or organ of the body to respond. Reflex action is the simplest kind of response exhibited to any stimulus. A reflex action results in the generation of a reflex arc. Reflex arc is the pathway travelled by the nerve during a reflex action. The stimulus initiates the receptors of the body which are connected to the sensory neurons. The sensory neurons convert the external stimulus into electric impulse and carry it through the association neurons or interneurons. They further connect the motor neurons and reach the brain to generate a response which travels the same way from the brain.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
