Answer:
The correct statements are listed below.
Explanation:
Vitamins are organic and minerals are inorganic.
Organic compounds comes from living things.Vitamins generally exist as organic compounds for example all the vitamin such as vitamin A, Thiamine,riboflavin,biotin,pyridoxin,vitamin c,vitamin E, vitamin K exist as organic compounds.
On the other hand minerals are found in inorganic form for example nitrogen is found as nitrate and nitrite,phosphorus is found as phosphate group,phosphoric acid.
Answer:
The correct answer is option (D) "His- strain grows on an his- plate".
Explanation:
The Ames test is a procedure that allows to detect if a given compound can cause mutations on a tested organism by growing strains of bacteria that require histidine (His-) to growth, since they are not able to produce its own histidine. In the Ames test, the bacteria is exposed to a given compound and is grown in a medium with small amount of histidine (his- plate). If the His- strain grows on a his- plate, it means that the bacteria has mutated to synthesize its own histidine and it is considered as a positive result on a the Ames test.

The replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.
<h3>How to calculate the Exponential growth/decay formula?</h3>
x ( t ) = x 0 × (1 + r ) t
- x(t) is the value at time t.
- x 0 is the initial value at time t = 0.
- r is the growth rate when r/ 0 or decay rate when r < 0, in percentage.
- t is the time in discrete intervals and selected time units.
Whit this information, we can conclude that the replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.
