I think an example would be, Humans are larger than they were 100 years ago. This is not a genetic characteristic .Phenotype is the composite of an organism's observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, behavior and products of behavior. The Genotype on the other hand is the genetic make up of an organism.

An extreme disturbance happens in an ecosystem. How does an ecosystem change as succession happens after this disturbance?
ddd [48]

Answer:

There is less biodiversity in the ecosystem.

Explanation:

Since the barren ground doesn't provide suitable living conditions for most of the living organisms, the ones that need the lest resources to survive create the primary succession, usually the mosses and lichens. The organisms of the primary succession provide biomass, so the ground is mixing with it, thus new soil is forming.

DNAase is an enzyme that catalyzes the hydrolysis of the covalent bonds that join nucleotides together. What would first happen
Free_Kalibri [48]

DNAase is an enzyme that catalyzes the hydrolysis of the covalent bonds that join nucleotides together. What would first happen to DNA molecules treated with DNAase?

A) The purines would be separated from the deoxyribose sugars.

B) The pyrimidines would be separated from the deoxyribose sugars.

C) All bases would be separated from the deoxyribose sugars.

D) The two strands of the double helix would separate.

E) The phosphodiester bonds between deoxyribose sugars would be broken.

Answer:

E) The phosphodiester bonds between deoxyribose sugars would be broken.

Explanation:

The purines and pyrimidines of two DNA strands of a DNA duplex are held together by hydrogen bonds. Hydrogen bonds are not covalent bonds. The enzyme DNAase targets the phosphodiester bonds. These are the covalent bonds that join two deoxyribonucleotides of a DNA strand together. therefore, when a DNA is subjected to digestion with DNAase enzyme, the phosphodiester bonds will be broken that hold the pentose sugars of two nucleotides by a phosphate group.
