Piaget believed that each child: a. progresses through a series of eight stages of psychosocial development. b. is biologically programmed to learn any language. c. actively tries to make sense of his or her environment. d. passively soaks up information about the world.

Piaget believes that each child actively tries to make sense of his or her environment.

Option C.

Explanation:

From the sensorimotor stage, to the pre-operational, followed by the concrete operational and formal operational, Piaget believes the growth and the evolving of the child is gradual, and the child tries actively (through different activities) to make sense/understand/comprehend his environment.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
