D) a change in protein synthesis
Answer:
C. Structure and Function
Explanation:
The reason as to why it is C is because, Structure means construct or arrange according to a plan; give a pattern or organization to, to put it more simple, the way something is built to help the way it functions. So for example, the structure of a hair brush is built to pull out the tangles, why would I use it on feet? It's not structured the way it will help function my feet. Function means, work or operate in a proper or particular way. Example: "bridges perform the function of providing access across water" Basketball shoes are "STRUCTURED" in a way it'll help the basketball player play better. You wouldn't wear boots to a basketball game because boots are structured in order to help the human feet get through the snow. Basketball shoes are structured in order to help it function so that the basketball player can move around freely on the court and play freely.
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.
Answer:
D

Gene pool is the total genetic diversity within a population or species
