Detailed explanation-1: -Reproduction. Oysters are broadcast spawners, distributing eggs and sperm freely in the water column, where fertilization takes place. Spawning typically occurs in the summer. Oysters are protandrous hermaphrodites, spawning first as males and then after 2-3 years, changing sex to spawn as females.
Detailed explanation-2: -A single female oyster can produce up to 5-8 million eggs at once and the eggs become fertilised in the water and develop into larvae. Eventually, a large number of small-sized offspring are produced. The offspring size ranges from a few millimeters to centimeters.
Detailed explanation-3: -Which of the following are molecular evidences for common descent?-All organisms use the same DNA triplet code and the same amino acids in their proteins.
Detailed explanation-4: -natural selection. The process by which organisms best adapted to their environment survive & reproduce to pass on favorable traits to their offspring.
