seasonal changes in the amount of day light
Answer:
The answer should be "The results failed to support the hypothesis that hummingbirds are most attracted to the color yellow" because in the question Rashad and Kendra made a hypothesis that the color yellow attracts hummingbirds more than other colors and carried out an experiment. Their results, however, contradict with their hypothesis as out of all the hummingbird feeders of different colors the one that is color red has the least amount of food left, therefore implying more visits from the hummingbirds.

<h2>A) option is correct </h2>
Explanation:
Skin has two types of sweat glands: eccrine and apocrine
Eccrine glands occur over most of the body and open directly onto the surface of skin whereas apocrine glands open into the hair follicle, leading to the surface of the skin and develop in areas abundant in hair follicles, such as on scalp, armpits and groin
The eccrine gland is controlled by the sympathetic nervous system and regulates body temperature
In some animals, when internal temperature rises the eccrine glands secrete water to the skin surface, where heat is removed by evaporation
Eccrine glands when active are considered major thermoregulatory devices
Smaller mammals, such as rodents, cannot endure dehydration and hence possess no eccrine glands at all
Chromosomes. and these words are only because it needs to be 20 characters
Answer:
Option A, Acquisition
Explanation:
The first stage of learning is known as acquisition. It causes establishment of responses by pairing of Neutral stimulus, conditioning and un-conditioning stimulus. Once the association between a neutral stimulus and conditioned stimulus is established, the responses are acquired.
For example – If a bird is trained to pick a key whenever there is a sound of a bell, then after certain period of time an association will be established between the “ringing of bell” and “picking up of key” activity. Therefore, whenever the bird will hear the ringing sound it will search for key to be picked.
Thus, option A is correct.
