Answer:
Overnutrition is food intake that is continuously in excess of dietary energy requirements
Undernutrition is inability to acquire enough food, defined as a level of food intake insufficient to meet dietary energy requirements.
Hope this helps:)
Limulus polyphemus are the source of cells for the LAL test used to detect bacterial contamination of surgical tools.
Limulus amebocyte lysate (LAL) is an aqueous extract of blood cells from the Limulus polyphemus which is used in LAL test. LAL test includes the reaction between LAL and bacterial endotoxin lipopolysaccharide (LPS), which is a membrane component of gram-negative bacteria. LAL test is widely used for the detection and quantification of bacterial endotoxins.
Answer:
A) nutrient A only
Explanation:
In this case, enzyme A is required for the digestion of nutrient A, thereby evidencing that the mutation affects the enzymatic pathway and the mutant strain only can grow by supplementation with this nutrient. In molecular biology, mutant strains are useful to study enzymatic functions (for instance, the role of enzyme A in nutrient assimilation), as well as to examine downstream signaling pathways.
In experimental design, spontaneous mutations are induced to study their effects on the phenotype. Subsequently, reverse mutations may also be induced to reverse the forward mutation, thus restoring the original wild-type phenotype.
I believe that it is form the Paleozoic era
Answer:
One is polar and the other is non-polar.
Explanation:
The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.
