Which three substances make up each of the smaller molecules that form proteins

The upper forelimbs of humans and bats have fairly similar skeletal structures, whereas the correspondingbones in whales have very different shapes and proportions. however, genetic data suggest that all three kindsof organisms diverged from a common ancestor at about the same time. which of the following is the mostlikely explanation for these data? a) humans and bats evolved by natural selection, and whales evolved by lamarckian mechanisms. b) forelimb evolution was adaptive in people and bats, but not in whales. c) natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy. d) genes mutate faster in whales than in humans or bats. e) whales are not properly classified as mammals.

Iwill mark you as brainliest pls 1) scientists can insert a gene into a bacterium. how does this biotechnology individuals with diabetes? a) a person with diabetes can regulate insulin production by eating products that contain the special bacterium and the new gene. b) the bacterium itself can be used as a treatment for a person with diabetes because it can deliver the genes for human insulin to that person’s cells. c) the insertation of a gene into a bacterium allows scientists to modify the gene that regulates insulin production. the new gene for human insulin can then be reinserted into someone who has diabetes. d) when the bacterium reproduces, it passes the gene for human insulin to its offspring. the offspring form a colony of bacteria that contain the gene for human insulin, which can then be used to produce insulin for a person with diabetes.
