A student would like to determine how heating a liquid changes its volume. The student hypothesizes that the liquid will increas

e in volume. The following list shows the steps taken by the student in order to test the hypothesis.
Select the liquid to test.
Place the liquid in a sealed container.
Use a Bunsen burner to heat the liquid by 10°C.
Measure the volume of the liquid.
Record the results.
What is wrong with how the student conducted the investigation?
A.
The student should have increased the temperature of the liquid by more than 10ºC.
B.
The volume of the liquid should be measured before it is heated.
C.
The length of time it took for the liquid to be heated should be measured.
D.
The hypothesis was not valid because it is impossible for liquids to change in volume.

Answer:

B.  The volume of the liquid should be measured before it is heated.

Explanation:

A student made serious mistake that he did not measure the volume of the liquid before heating.

The scientific experimentation along with care and attention need a proper protocol which a scientist needs to follow to get the results.

The initial hypothesis of the student shows that he wants to know the change in volume, so it is inevitable to calculate the initial volume to know the difference after the completion of experiment.

<em>All other options seem less appropriate than Option B, therefore B is the right answer.</em>

I hope it help!

A main job of hcl is to begin _______ digestion. carbohydrate fat protein
s344n2d4d5 [400]
The answer to this is protein.

Hydrochloric acid in digestive system is found in stomach, which is the only main digestive organ with an acidic pH 2.

In the stomach, only one kind of the primary food substance is chemically digested, which is protein. It is digested with the help of enzyme Pepsin, which breaks protein chains into polypeptides.

After that, the other organs of the digestive system has more of a neutral to slightly alkali condition, which is not related to hcl. Therefore, the answer is protein.

A phagocytic cell has a mutation in a gene for a hydrolytic enzyme that renders the enzyme nonfunctional. What is the most likel
pshichka [43]

Answer: The phagocyte’s ability to destroy the ingested pathogen is compromised and it will become inactive.

Explanation:

There are different hydrolytic enzymes. Lysozyme attacks cell walls of gram positive bacteria. Elastase is a protease. Collagenase attacks collagen, produced by some bacteria. Plasminogen activator is also a protease.

Loss of function of any one of these enzymes will reduce or prevent the breakdown of bacteria in the phagosome (vacuole) so that the phagocyte is inactivated.
