The answer is A. 0.54.
In a population p+q=1 (we have 2 alleles only).
The question states that 0.21 of the population(21%) have short legs meaning they are q^2.
So q=rad0.21=0.4582.
And p=1-q=0.5417.
Oxygen-16 and Carbon-12 are stableisotopes of elements O and C respectively. Hence, they do not have half-lives. But Carbon-14 andUranium-238 are radioactive isotopes. Among them Carbon-14 has relatively short half-life as about 5730 years while Uranium-238 has a long half-life as about 4.5 billion years.
Answer is. uranium-238
Answer:
During interphase, a cell is metabolically active
Explanation:
Cell cycle is divided into two stages: interphase (lasts 3/4 of the cycle) and phase M (1/4 of the cycle).
Interphase is also divided into three stages:
Phase G1
Protein and RNA synthesis is done.
Phase S
DNa synthesis is done.
Phase G2
Protein synthesis continues and the cell grows to start the division.
Ans : C - enzymatic action on carbohydrates ( enzyme amylase catalyses carbohydrate to maltose here in the mouth )
