Are there any answer choices? Is so, please post.
Answer:
Plants absorb most blue light
Explanation:
There are few blue colored plants because most of the plants absorb blue color and thus resulting in few blue plants.
Answer:
American Kennel Club = 202 dog breeds
Kennel Club = 211 dog breeds
Federation Cynolgique Internatioinale = 344 breeds
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.
Essential services, such as water purification, nutrient cycling, and plant pollination are all examples of earth's Ecosystem services.
The ecosystem is defined as the interaction between the biological communities with its physical environment. The services provided by the ecosystem are termed as ecosystem services. The ecosystem with the help of its different components performs water filtration, recycling of the nutrients, pollination, seed dispersal etc. These all services provided by the ecosystem comes under the category of ecosystem services.
