Why do you think that parasitism exists, when one of the organisms is harmed by the relationship?

Because although one organism is harmed, the other benefits. So the organism that benefits won't stop the action that is harming the other. Hope that makes sense!

EastWind [94]

Answer: Option a) the frequency of the homozygous dominants will go down, the frequency of the heterozygous genotype will go down, and the frequency of the homozygous recessives will go up

Explanation: Another name for gene frequency is the allele frequency. It is the percentage of any chromosomes in the population that contains that particular gene or allele. It also shows the genetic diversity that can present in a species.

Polysaccharide digestion and glycogen breakdown involve sequential cleavage from ________ ends of glucose polymers.
Alex787 [66]

Sequential cleavage from the non-reducing terminals of glucose molecules is required for both glycogen degradation and polysaccharides hydrolysis.

Why non-reducing end is selected for digestion?

A polysaccharide's non-reducing end is the one where an anomeric carbon participates in the glycosidic connection. The elimination of carbohydrate remnants one at a time out from the non-reducing terminal occurs during glycogenolysis and polysaccharides hydrolysis.

  • For example, several enzymes are involved in glycogenolysis in the liver and muscle.
  • An example of such an enzyme is glycogen phosphorylase, which catalyzes the successive dissociation of the alpha 1->4 glycosidic bond that connects two glucose molecules at a non-reducing terminal of glycogen. The last glucose residue is eliminated as alpha-D-glucose 1-phosphate.

That is why non-reducing end of glucose is chosen for digestion or breakdown of the carbohydrate polymer.

The investigations conducted by Edwin Chargaff support the idea that DNA is the source of heritable information, and they also s
siniylev [52]

all the thymine pairs with adenine, therefore there is the same number of adenine and thymine bases and the same percentage

so we have 28%thymine and 28% adenine

100-28-28=44% left

this 44% is guanine and cytosine. All of the guanine pairs with cytosine and all of the cytosine pairs with guanine so we have 44/2=22% cytosine and guanine

composition:

28%adenine

28%thymine

22%guanine

22%cytosine
