Because plants go through a cycle(the cycle is seed, seedling, plant, flower and tree.) and it takes time for the plant food, water, and nutrients to go though the plant.
Points C and D are correct statements for Natural Selection.
Natural selection is the process by which organisms develop variation in traits, which gives them the better chance of survival and Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Explanation:
Darwin postulated in his theory that over a period of time there are changes in physical or behavioral traits which are transferred from parent to the next generation. The changes which led to the better adaptation to the environment will help survive the organisms. Such organisms will reproduce.
There are choices for this question namely:
<span>A) genetic bottleneck.
B) sexual selection.
C) habitat differentiation.
D) founder effect.

The correct answer is founder effect. The definition of founder effect is the loss of genetic variation when a new population is established in a small number of individuals from a larger population. The larger population in the context is the ecosystem in Hawaii before it rose from the sea surface. After it rose above the sea surface, most organisms will not be able to survive in land but there will be a small population that can evolve from there.
When the parents have recessive genetic disorder with the genotype gg, there are 100% chances that their second child will develop the disorder.
Genotype is the genetic makeup of an individual. It tells about the set of alleles a person exhibits for a particular trait. Recessive genetic disorder is an autosomal kind of disorder in which both the alleles inherited from the parents should be recessive. Sickle cell disease is an example of recessive genetic disorder.
When both parents are recessive for a trait, only one type of gamete is formed that can give rise to offspring with only the homozygous recessive trait.
