he size of the fox population will . . . a increase. An increase in the size of any population leads to an increase in the sizes of all other populations in an ecosystem. increase., An increase in the size of any population leads to an increase in the sizes of all other populations in an ecosystem. b stay the same. Possums and foxes do not eat each other, so the number of births and deaths in the fox population will stay the same. stay the same., Possums and foxes do not eat each other, so the number of births and deaths in the fox population will stay the same. c decrease. The larger opossum population will leave fewer energy storage molecules for all other populations in the ecosystem, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.

Aboy with an extra x chromosome probably has which of the following syndromes?

Why does meiosis produce cells with half the chromosomes? o a. most of the chromosomes are not necessary to keep an organism alive. b. a gamete needs only half the number of chromosomes because two gametes join together. o c. it makes the gametes easier to move around in the organism. o d. it is faster to produce gametes with fewer chromosomes.
