Benthos live in the benthic zone. The benthic zone is the lowest level in a body of water. Bentho organisms include things such as crustaceans and polychaetes
Answer:
Recessive
Explanation:
All of the offsrping were black so that means black was the dominant gene and white was the recessive
The best option for showing locations of housing and industry on a city map is drawing a circle around the industrial areas. Thus option "C" is correct.
<h3>What are general reference maps?</h3>
Road maps and historical maps are general reference maps as it shows the physical (natural and man-made) features in an area and can use different colours to differentiate different rods and locations.
Early formed maps or historical maps are general reference maps as it can represent the discovery of a landscape briefly.
Thus option "C" is correct.

Answer:
The correct answer is: d. REs activity is best preserved by freezing the RE and thawing it out for brief periods of time as needed.
Explanation:
- Restriction enzymes can be defined as endonucleases that can recognize specific nucleotide sequence in a DNA (Deoxyribonucleic acid) sequence and cause breakage of phosphodiester bond in the DNA at the target site. Hence, it has the capacity of cleaving a DNA sequence.
- These are made up of proteins which are required to be present in the accurately folded conformation in order to function.
- Any form of alteration in the three-dimensional structure of the protein induced due to physical, chemical, mechanical or physiological factors can cause denaturation of the protein which in turn can render the protein non-functional.
- Freezing of restriction enzymes (REs) directly without the use of glycerol will cause the movement of water molecules within the proteins as well layering of water molecules on the protein surface.
- At low temperature these water molecules change to ice crystals which can alter the conformation of the protein or can cause breakage of peptide bonds in the proteins by physical force.
- This can cause the protein to get denatured and hence non-functional.
- Hence, it is never advisable to preserve REs by freezing directly without glycerol.
- Glycerol forms a layer around the protein molecules and prevents the protein molecules from coming into direct contact with the water molecules and hence prevents protein denaturation.
The Adipose tissue mainly works as storing energy into fat but it also works as an insulating layer that allows less heat to escape the body, as well as offer protection to major organs.
