Answer;

Evolution

Mutations such as polyploidy and crossing over provide the genetic basis for evolution.

Explanation;

Evolution is the change in the characteristics or traits of a species over several generations and relies on the process of natural selection.

It occurs when some individuals or some alleles (alternative form of gene) reproduce themselves more than others,increasing their prevalence in subsequent generation.

Polypoidy and crossover brings about mutations that cause changes in characteristics and traits over time resulting to evolution.

What is the main purpose of light-dependent reactions of photosynthesis?

liq [111]

Answer:

The main purpose of light dependent reactions of photosynthesis is to generate ATP and NADPH.

Explanation:

Photosynthesis consist of two reactions 1 light reaction 2 dark reaction .The light reaction occur in the thylaKoid of Grana to produce Adenosine tri phosphate (ATP) and NADPH

Role of ATP

ATP is an energy rich molecule which undergo hydrolysis to provide energy for Carbon di oxide fixation during dark reaction. The carbon di oxide fixation is very much important to produce glucose.

Role of NADPH

NADPH act as reducing equivalent that carry out the reduction of phosphoglyceric acid formed in the first step of light independent reaction to generate phosphoglyceraldehyde(PGALD). Some PGALD then undergo various enzymatic reaction to form glucose and rest are utilized to regenerate ribulose bis phosphate(RUBP).

IF Avery, Macleod, and McCarty had found that samples of heat-killed bacteria treated with RNase and DNase transformed bacteria,

natali 33 [55]

Answer:

See the answer below

Explanation:

The conclusion that Avery, Macleod, and McCarty would have made assuming that samples of heat-killed bacteria treated with RNase and DNase transformed bacteria, but samples treated with protease did not would be that protein is responsible for the transformation of the non-virulent bacterium strain to a virulent one.

According to the findings of the 3 researchers, heat-killed virulent strain of Streptococcus pneumoniae transformed non-virulent strain of the same species into being virulent. They were able to discover that the molecule responsible for this transformation was DNA.

If the heat-killed virulent strain had been treated with RNase and DNase, this would have degraded RNA and DNA in the heat-killed cells respectively, leaving only protein as the carrier of the virulence factor. Confirmation of the transforming attribute of the protein can be further be confirmed by treating the heat-killed mixture with protease, a protein degrading enzyme.
