<span>The correct answer is C.
It reaches sexual maturity at 15 years of age.
K-Selection is termed as the selection of combination of traits in an organism.
They trade off between quality and quantity of offspring. This theory was used as a heuristic device. K-selection theory, selective pressure are hypothesized to drive evolution in one generalized direction.
The best example which illustrates this k-selection is a polar bear producing one two cubs for every period of three years.</span>
Facilitated diffusion and D. simple diffusion are alike since neither requires energy.
Simple diffusion<span> can only move material in the direction of a concentration gradient; facilitated </span>diffusion<span> moves materials with and against a concentration gradient.</span>
D. A mouse and a human have about the same number of genes.
Explanation - The number of chromosomes does not determine the complexity of the organism. A mouse and a human have approximately same number of genes. Mice is biologically the same as people since they perform comparable capacities and procure comparative diseases as people.
That is why several experiments are conducted in mouse to understand how the reaction will take place in humans. After all the trials are passed, then the experiment is conducted on humans.
