Answer:
Hello!
The answer is D) Homeostasis
Explanation:
Homeostasis:
<em>The regulation of a cell or an animal's internal environment in response to fluctuations in the external environment is called homeostasis. </em>
Homeostasis is crucial to maintain an optimum environment for cell structures to work effectively.
In this case, the jackrabbiit's circulatory system is responding to fluctuating temperatures. In hot days, the body is at risk of heating up above optimum temperature which could hamper body functions. Therefore, the blood flow to the ears is increased to facilitate heat loss.
In cold temperatures, the blood flow to the ears is decreased to conserve heat for vital body organs. The blood flow is directed to the core of the body to protect the heart, lungs, liver and brain.
Nutrients are delivered by the blood through the capillary network.
Answer:
E. Merkel cells.
Explanation:
Merkel cells are located in the deepest layer of the epidermis. These cells are in contact with the flattened process of a sensory neuron. These flat processes are called a tactile disc or Merkel disc. Merkel discs are slowly adapting touch receptors. These receptors are specifically abundant in fingertips, lips and external genitalia. Markel cells and their associated Merkel discs are involved in the detection of touch sensations. They respond to respond to continuous touch such as holding an object in hand for long and help in distinct detection of shapes and texture of various objects.
