Answer:
DNA in each of the two daughter cells would have half of the radioactivity as compared to the radioactivity of the DNA of parent bacterium
Explanation:
DNA replication is a semi-conservative process and each of the newly formed double helices contains one parental strand and one newly formed DNA strand. The parent bacterium had both of its DNA strands radio-labeled. Replication of the parent DNA would form two DNA double helices each of which would contain one radio-labeled parental strand and one non-labeled newly formed DNA strand. Therefore, DNA of each daughter cell would exhibit half the radioactivity as that of the parental DNA.

Answer:
A) A single base pair change.
Explanation:
Point mutation is a change in a single base pair of a nucleotide. This comes as a results of mistakes made during DNA replication, induced by ultravoilet radiations, extreme heat and X-rays. There are three types of point or substitution mutations; change, deletion and insertion. The nucleotide bases are either mistakenly inserted, changed or deleted, thus changing the resulting protein or amino acid being coded for.
Answer:
A. oxygen and sugar are used in the process that provides energy to cells, water and carbon dioxide are given off.
Explanation:Respiration is a biochemical process that uses oxygen and glucose to generate energy with the release of carbondioxide and water. All organism respires and the oxygen is used for cellular respiration.
C6H1206 +6O2----6CO2+6H2O+Atp(energy)
The Co2 and H2O is used by plant for the process of photosynthesis in producing there food.
