Each question or incomplete statement is followed by five possible answers or completions. Sleect the one choice that is the best answer.
1. All of the following contribute to variation in a population EXCETP
(C) sexual reproduction
(E) genetic drift
2. Tendons connect _________________ to ____________________; ligaments connect __________________ to ________________.
(A) bone to bone; bone to muscle
(B) bone to muscle; bone to bone
(C) bone to bone; muscle to muscle
(D) muscle to muscle; bone to bone
(E) ligaments to bone; tendons to bones
3. A solution of pH of 5 is _______ times more acidic than a solution with a pH of 7.
4. Farmers have successfully bred Brussels sprouts, broccoli, kale, and cauliflower from the mustard plant. This demonstrates
(A) convergent evolution
(C) adaptive radiation
(D) natural selection
(E) artificial selection
Variation in a population results from an influx or development of new genetic material. Conjugation is a primitive form of sexual reproduction carried out by bacterial and algae. If a population is isolated, there can be no flow of genetic material.
Tendons connect bone to muscle; ligaments connect bone to bone.
A solution of pH 5 has H^+ concentration of 1 x 10^-5 M or -0.00001 M. A solution of ph7 has H^+ concentration of 1 x 10^-7 M or -0.0000001 M. You can see that 0.00001 M is 100 times more concentrated than 0.0000001 M.
Artificial selection is the selective breeding of domesticated plants and animals to develop desired traits.
