Snakes and lizards are reptiles. Both organisms have pelvic organs, even though snakes don’t have hind legs. What are the best explanations for this situation? Snakes evolved from lizards, and the hind legs are vestigial in nature.
Snakes and lizards share a common ancestor.
Snakes and lizards belong to same species.
Lizards evolved from snakes, which lost their hind legs during evolution.
Lizards and snakes don’t share a common ancestor.

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.

Which of these serves as a reference for comparison during a scientific investigation? a)outcome variable (dependent variable) b) test variable (independent variable) c)control group d)hypothesis
