Option D is correct
Explanation:
Luria broth contains yeast concentrate so it would show a marked B- galactosidase activity which is an enzyme that catalyzes the hydrolysis of B- galactosides including lactose and it is the first step of lactose fermentation.
The correct answer is option A
The burning of fossil fuel releases carbon dioxide in the environment. Carbon dioxide is the main green house gas. The green house gases work by trapping the heat that comes inside the earth from the sun.
The carbon dioxide is the green house gas that traps maximum heat coming from the sun. If the carbon dioxide would not have been there then the temperature of the earth would have been very low and the atmosphere would have been colder.
But the global temperature is rising due to lost of carbon dioxide present in the environment as the burning of fossil fuels is increasing day by day.

Carbon

Plant cells are specialized for life in a hypotonic environment.
Answer: Option A
<u>Explanation:</u>
A cell which lacks the cell wall, will expand and burst. At the point when set in a hypertonic solution, a cell without a cell wall will lose water to the surrounding, wilt and presumably die.
In a hypertonic arrangement, a cell with a cell divider will lose water as well. The plasma layer pulls from the cell wall as it withers, a procedure called plasmolysis. Thus it can be inferred that plant cell are specialized for life in a hypotonic environment.
22% cytosine, because each pair has an equal amount of complementary base percentages. For example, if you are given 20% Adenine, then there has to be 20% Thymine as well, and you can also calculate cytosine and guanine by looking at the remaining percentage (80%). Because 80% is left over and each complementary base pair has equal amounts of base percentages, Cytosine and Guanine would each have 40%.
