Answer:
The 3.9 billion year old rock has undergone three half-lives (3.9 divided by 1.3 = 3). After 3 half-lives, 12.5% of the potassium-40 remains undecayed.

Answer:
The correct answer is option e, that is, a, b and c.
Explanation:
The phenomenon by which green plants and other species converts light energy into chemical energy is termed as photosynthesis. During photosynthesis, the energy of the light is captivated and is utilized to transform carbon dioxide, water, and minerals into oxygen and energy-rich organic components.
With the transport of electron through the chloroplast membrane, the energy of the electron causes the diffusion of a hydrogen ion from stroma into the thylakoid lumen, which further leads to a formation of hydrogen ion concentration gradient. This gradient ultimately results in the formation of ATP.
The correct answer is - a. It will reduce genetic diversity.
The pumas that live in Florida, also known as the Florida Panthers, will have a much reduced genetic diversity. The reason for this is that the population is very small. It also lives in the same area, where the living conditions are the same. The genetic pool is very small, and the breeding is going on between individuals that have the same traits, and are also relatively closely related, as the mating occurs between the second or third generation that came out form the same parents. That will result in a very reduced genetic diversity, so the Florida Panther will remain the same if the conditions do not change drastically, or these an invasion of pumas from the west into their territory.
