Answer:

He should look out for tiny leaf-like structures which mosses possess but algae does not .

Explanation:

In general, moss looks fibrous, feathered or latticed when viewed up close. Carpets of moss are springy to the touch. When germinating, moss puts up thin stems sometimes with leaves on top and reproductive spores. Algae have no threadlike structures or leaves. Instead, algae spread as a clump of living cells. Because algae usually grow in wet environments, they look like a slimy, wet mass, often green in color. Both moss and algae may appear green or brown depending on species and the dryness of the conditions.

From the graph, we can conclude that catalase has a low activity at low temperatures. Activity increases a little at 30°C and this process is the highest at 40°C, after this temperature, activity disminishes again.

Options:

A. This option is wrong because the number of bubbles at this temperatures is low, maybe the enzyme is already denatured.

B. This answer is wrong, at 30°C the enzyme shows a low activity.

C. This answer is correct because at this temperature the enzyme produces the higher amount of bubbles.

D. The activity of the enzyme at 0°C was not tested.

The protein coat that surrounds the genetic material of the T2 phage is termed the:______
tiny-mole [99]

Answer:

Th correct answer is A. Capsid

Explanation:

T-2 phage is a bacteriophage which is virulent to E.coli which means T2 phage infects E.coli. The genetic material of T2 phage is linear DNA which is double-stranded. The genetic material of T2 phage is enclosed in a protein coat which is called capsid.

This capsid protects the genetic material of bacteriophage by any enzymatic digestion, helps the virus to attach the host cell and helps the virion to penetrate the cell membrane of the host cell and inject its genetic material in the host cell. Therefore capsid is the correct answer.

Describe how hydrogen bonds relate to surface tension.
Lelu [443]

Answer:

Hydrogen bonds provide higher surface tension to a liquid. If you disrupt hydrogen bonds, surface tension will decrease. That's why at high temperature, surface tension is lower due to disruption of hydrogen bonds. Hydrogen bonds can be disrupted by the addition of surfactants and surface tension can be reduced also. Detergent is a surfactant because it  interferes with the attractive forces between the water molecules.
