false
Explanation:
These different faces are called phases and they are the result of the way the Sun lights the Moon's surface as the Moon orbits Earth. The Moon can only be seen as a result of the Sun's light reflecting off it. It does not produce any light of its own.
Answer:
True
Explanation:
The Polymerase Chain reaction (PCR) is a technique widely used in molecular biology to identify specific DNA fragments generally in a size range of 100 to 1000 base pairs (bp). PCR sensitivity refers to the potential of the PCR technique to specifically amplify the desired sequence in the sample. PCR is a highly sensitive (and also specific) method with values around 100% if the experimental conditions are proper. However, to reach these values, it is imperative to work in optimal conditions by eliminating contaminant factors in the sample which may alter PCR amplification.
Answer:
Affected animals given a galactokinase inhibitor do not experience toxicity.
Explanation:
Galactokinase: Catalyzes is the first and committed step of the Leloir pathway involving the conversion of galactose to glucose. It causes phosphorylation of α-D-galactose to galactose 1‑phosphate. Thus, inhibiting galactokinase wil greatly decrease the levels of galactose 1‑phosphate.
