Fossils are an remnant, impression, or trace of an animal or plant of a past geologic age that has been preserved in the earths crust.
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.
Foods that contain substantial amounts of vitamin A include beef liver, spinach, broccoli and liver oil.
<h3>What is vitamin A?</h3>
Vitamin A is a fundamental micronutrient that must be ingested in the diet in suitable amounts.
Leafy green vegetables (such as spinach) or orange vegetables (such as carrots) contain many vitamin A.
