Which statement is true about crossing over of genes? a. crossing over does not occur between genes that are far apart from each other on a chromosome. b. frequency of crossing over is related to the distance between linked genes. c. genes that are close to each other frequently cross over.

B

Explanation:

The closer together that particular genes are to each other, the less likely that they will separate during crossing over and the more likely that they are inherited together by offspring – this is a test of linkage of genes. Genes on separate chromosomes are more likely to cross over than genes on the same chromosome.  

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

answer: glucoamylase presented optimum activity at temperature of 55â°c, and, in the glycosidic bonds from the non-reducing ends of starch, resulting in the production of glucose. source and type of fermentation can affect the enzyme's properties
