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.

Salivary amylase enzymatically breaks down glucose in the oral cavity. true or false
masha68 [24]

Answer:

FALSE

Explanation:

Digestion begins in the oral cavity when food enters in contact with the salivary amylase, the principal enzyme in saliva. Carbohydrates in the form of starches (like potatoes, rice, or pasta) are hydrolized from polysaccharides into disaccharides, amylose and amylopectin are hydrolyzed into smaller chains of glucose (dextrins and maltose). This step in the digestion of sugars is limited due to the brief exposure time of the food to the enzyme.

<em>Therefore we can conclude that the answer is FALSE because salivary amylase enzymatically breaks down polysaccharides into disaccharides, glucose is not broken down at this point. </em>

I hope you find this information useful and interesting! Good luck!

kirza4 [7]

Answer:

They make it themselves! Plants are called autotrophs because they can use energy from light to synthesize, or make their own food source. Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive.
