Which of the following is not true of saliva?A. cleanses the mouth
B. contains enzymes that begin the breakdown of proteins
C. moistens food and aids in compacting of the bolus
D. dissolves food chemicals so they can be tasted

Answers

Answer 1
Answer: The answer is B. contains enzymes that begin the breakdown of proteins.

Saliva is watery substance secreted by salivatory glands. It cleanses the mouth and maintenance oral hygiene. It moistens the food, so the created food bolus could easier pass into the esophagus. It also carries food chemicals to taste receptors so they can be tested. It contains enzymes involved in the food digestions. Some of them are amylase, which begins the breakdown of the starch, and lipase, which begins the breakdown of triglycerides. There are no enzymes in the saliva that break down proteins.
Answer 2
Answer:

Final answer:

Saliva cleanses the mouth, moistens and compacts food, and dissolves food chemicals for taste.

Explanation:

Saliva is a clear liquid that is produced by the salivary glands in the mouth. It serves several important functions in the digestive process. It keeps the mouth clean by cleansing it and helps to remove food particles. Saliva moistens food and aids in the compacting of the food into a bolus, which can be easily swallowed. Additionally, saliva contains enzymes such as amylase that begin the breakdown of carbohydrates, not proteins. Lastly, saliva dissolves food chemicals so they can be tasted.

What is the Breaking down of amino acids into urea and uric acids?

Answers

The breakdown of amino acids into urea and uric acids take place in the urea cycle, a biochemical process. 
Aspartate directly donates a nitrogen atom from the formation of urea during the urea cycle.
The argininosuccinate synthase reeaction links aspartate and citrulline via the amino group of aspartate and provides the second nitrogen of urea.
The breaking down of amino acids into urea and uric acids is called Catabolism; from organelles to cells to blood circulation by amino acid transporters. Then, it goes to the liver and the kidneys in the degradation of the amino acid. After the urea cycle; it will then be excreted in the form of urea.

Dr. Smith has discovered a bird that he believes is a new species. Dr. Wilson says he will only be convinced if Dr. Smith finds several more of the same type. Why might Dr. Wilson feel this way?

Answers

Answer:

The correct answer is - he wanted to be sure before considering before the bird as a new type if it really represents new species.

Explanation:

Dr. Smith has found the bird that he considered as new species however Dr. Wilson said he will only be convinced if DR. smith could find several members of the same species. Dr. Wilson seems to be sure before considering the bird that Dr. smith found as the new species. It is because he wants to sure if it's not an unusual example of the pre-described species.  

Thus, the correct answer is - he wanted to be sure before considering before the bird as a new type if it really represents new species.

Which would have the GREATEST effect on the rate of photosynthesis in a plant? A) oxygen level B) light intensity C) sugar concentration D) starch concentration

Answers

The correct answer is option B, Light intensity

Reason -

Light intensity plays a major role in the regulation of photosynthesis. In the absence of light a plant is unable to photosynthesize. As the plant receives light through the chlorophyll , essential chemical reactions takes place thereby releasing free electrons which keep on driving the further processes or reactions in a plant to produce food and oxygen and energy..  

The higher the light intensity, the higher is the rate of photo synthesis

Oxygen levels make no impact, they need CO2.
Sugar concentration makes no impact as that is a product.
Starch makes no impact.
Only light from the choices above is the factor in photosynthesis that could have the greatest effect as it is not a product yet a reactant
