Answer:
C
Explanation:
Natural Selection can cause micro evolution, or a change in allele frequency over time
Answer:
The correct answer will be - in the bacterial cells
Explanation:
The complexity of life began on Earth when the simple amoeba-like organism started ingesting the bacterial cells. The ingestion of the aerobic respiration performing bacteria formed the mitochondria and ingestion of the photosynthetic bacteria formed the chloroplast of the cell. The bacteria while evolution lost their identity and now cannot live without the host cell.
This hypothesis was supported by the evidence like a comparison of the Ribosomes of this organelle is similar to the prokaryotic bacteria as the bacterial cell.
Thus, in the bacterial cells is the correct answer.
Phylogenetic bracketing is a technique for surmising utilized as a part of organic sciences. It is to deduce the probability of obscure attributes in life forms in view of their position in a phylogenetic tree. One of the primary utilizations of phylogenetic sectioning is on wiped out creatures, known from fossils.
Answer:
Ethanol is most likely to be a (B), competitive inhibitor.
Explanation:
The poisoing occurs because of the harmful metabolites produced by the alcohol dehydrogenases, enzymes in charge of breaking down alcohol.
Hence, the most likely strategy of an antidote is to compete for the active site of the enzyme and prevent the methanol convertion to harmful chemicals.
Ethanol does not produce these metabolites and it is preferentially proccessed by the body, so it is a competitive inhibitor, competing for the active site.
