<h2>Answer:</h2>

Lysosomes are organelles that contain digestive enzymes (acid hydrolases). They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria. The membrane surrounding a lysosome prevents the digestive enzymes inside from destroying the cell.

As it turns out, our tears do contain some magic, namely the powerful enzyme lysozyme. This enzyme is crucial in thwarting bacteria that attempts to enter our body cavities. By destroying the peptidoglycan layer of bacterial cell walls, it serves as a strong chemical defense against bacterial infections.

Pretend scientist discover an enzyme in the human body that works best at 39 degrees Celsius. What process would this enzyme mos
Ymorist [56]

Answer:

The normal body temperature for humans is 37 degrees Celsius. Most of the enzymes of a human's bodywork best at this temperature. If an enzyme was discovered which works best at 39 degrees Celsius, then it means that the enzyme works at elevated temperatures for events which require slightly higher temperatures.

The enzyme will most probably work for overcoming fever or for reducing the temperature of the body after exercise.

UkoKoshka [18]

Answer:

Option A, shared their data with colleagues to obtain feedback on the work.

Explanation:

All researchers prefer to share their findings with their peers or other researchers working in the same field to get their reviews. This step is very essential as it makes the research authentic and removes the flaws that would have otherwise missed by the researcher.  

Peer reviewers also give useful suggestion to further modify one’s research study based on their experiences.  

Hence, option A is correct

prohojiy [21]

Answer:

The statement that best explains the mechanisms of inheritance of gene "The allele for blue is an X-linked dominant allele because there are no blue male offspring in cross 2."

Explanation:

The mechanism for inheritance of gene is the condition, in which the mutation when happens in one allele and cause the effect in the relevant phenotype. Similar inheritance will also be seen when the mutated allele will produce new type of the protein which will have deletorious effect on the normal function of the cell. In case of the single gene, autosomal dominant, autosomal recessive, X-linked dominant, X- linked recessive and mitochondrial are modes of inheritance.

The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angle
Nadya [2.5K]

Answer:

2(8x^2-13x+10)

Explanation:

There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.

Let's let A represent the measurement of one of the those angles in our pentagon.

The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.

But we are also given that this equals 40x^2-65x+50.

So that means 5A=40x^2-65x+50.

If we divide both sides by 5 we can find what one of our angles is in terms of x.  So let's do that A=8x^2-13x+10.

So we want to know the sum of two our angles, we want to know what is A+A or 2A.  2A=2(8x^2-13x+10).  To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.
