You can identify your customers by grouping them according to certain characteristics that you believe may be of importance to you. This is called demographics. This will help you not only know who your customers are, but also how you would be able to deal better with them. I hope this help if not just comment and I will get a notification to help again
Answer:
610:190 round seeds: wrinkled seeds
Explanation:
A cross between two true breeds, involves crossing two parents that are each homozygous for the traits they carry.
A cross between a true breeding round parent (RR) and a true breeding wrinkled plant (rr), will produce all heterozygous offspring:
Rr : 100% in the F1 generation.
When these heterozygous offspring are crossed, Rr x Rr, the proportion obtained genotypically in the second filial generation is:
- 25% homozygous round (RR)
- 25% homozygous wrinkled (rr)
Considering the importance of dominance in phenotypic expression, round seeds being dominant over wrinkled seeds, indicates that about 75% of the offspring are expected to appear round and 25% expected to appear wrinkled. Putting this phenotypic proportion into perspective,
<em>610:190 round seeds:wrinkled seeds,</em> is the ratio in line with the proportion expected to see in the F2 generation.
Well, in a way it is true, as, chloroplasts are the reason why plants photosynthesize. So, with the photosynthesis, it releases oxygen, which is the power generator for life on Earth, as we breathe in oxygen.
Answer:
Explanation:
A protease is an enzyme that catalyzes the hydrolysis of the peptide bonds that tie polypeptide chains together, releasing individual amino acid subunits. The L and D nomenclature for amino acids defines the structure of the glyceraldehyde isomer through which the amino acid can be produced.
SEE BELOW FOR THE APPROPRIATE STRUCTURES.
We need to figure out why swine proteases hydrolyze L-amino acids but not D-amino acids in any way. we know that enzymatic catalysts act as polypeptides if you can recall. They must retain a very precise three-dimensional structure for a catalytic activity to occur. Substrates that do not quite match the required configuration at the active site will not be reacted to — this is a "lock and key" style.
The present exercise may be explained by the fact that the configuration and structure of D-amino acids prevent them from binding properly to the active site of the protease enzyme. Perhaps they're pointed in the wrong direction, or perhaps there happens to be missing electrical interaction that's needed to keep the substrate in position.
Nonetheless, L-amino acids, on the other hand, seem to have the right configurational aspects in the active site and are hydrolyzed.
