Answer:
Option (2).
Explanation:
Ames test is used to identify the mutageneicity of the compound. The bacteria are treated with chemicals in the nutritive environment to determine whether the substance can acts as a mutagen or not.
The bacteria that can restore the biosyntheic activity in the environment can be considered as mutagen. The mutant bacteria can be easily identified in the Ames test.
Thus, the correct answer is option (2).
Answer: Atmosphere
Explanation:
Atmosphere is the part of the earth, known as the gaseous part, since it contains gases such as nitrogen (about 78%), oxygen (about 21%), Carbondioxide (about 0.03%), and rare gases to make the rest.
Thus, atmosphere contains the most whole of oxygen and carbon dioxide
Answer:
The correct answer is C. A buildup of lactic acid in the tissues.
Sore muscles after vigorous exercise are the result of lactic acid accumulation in the muscles.
Vigorous exercise reduces the levels of oxygen available in the muscles due to which complete oxidation of the glucose could not take place.
Muscle cells switch to another process called as lactic acid fermentation to produce energy. In this process, lactate dehydrogenase converts pyruvate into lactate and reduces NADH to NAD⁺.
This NAD⁺ enables the continuation of glycolysis which results in the production of net 2 ATP.
In addition, influx of materials such as nutrients, WBC, anti-inflammatory compounds etc into the muscle cell (for repair) causes swelling of the muscle fibers which is also the reason for the muscle soreness.
Answer:
having crops that can grow at any temperature is the answer!
The condensation stage is where water turns into vapor which forms into clouds and if we don't have condensation we won't have clouds and we won't have participation (rain). <span />
