Answer:
Cellular Respiration
Explanation:
In cellular respiration, animals take in O2 (oxygen) and exhale CO2 (carbon dioxide).
One advantage of genetic engineering is the production of valuable proteins: recombinant DNA made possible the use of bacteria to produce proteins of medical importance such as genetically engineered human insulin which is of great importance.
Another advantage is the production of vaccines. Vaccines produced by genetic engineering offer an advantage that the microbial strains from which proteins are extracted do not contain complete viruses and thus there is no risk of accidental inoculation with live virus.
Answer:
The consequences will depend on the type of mutation. For example, if the mutation is synonymous it will not have negative effects on the cell function. On the other hand, if the mutation produces amino acid diversity it may cause loss of function
Explanation:
Primase is an RNA polymerase that adds RNA nucleotides to the complementary DNA strand in order to prepare it for the RNA polymerase III during transcription initiation
D. a cell wall.
reasoning: in a prokaryotic cell, they have no nucleus or organelles. a cell wall is the only answer that is neither of those.
With the choices given, the answer to the biology question presented above would be b. heavy metals such as mercury. Heavy metals contribute to soil pollution more than air pollution. The other choices are sources of air pollution. Thus, letter b is the answer.
