Which of the following is a characteristic of the human organism? A. Autotrophic with a genome stored in DNA B. Heterotrophic with a genome stored in DNA C. Autotrophic with a genome stored in DNA D.Heterotrophic with a genome stored in RNA Which of the following cell types is re- sponsible for the production of soluble antibodies? A. Cytotoxic T-Cell B. macrophage Cell C. Helper T-cell D.B-Cell A person is suddenly frightened. Which of the following reactions occurs next? A. liver cells absorb glucose from the blood stream. B. Blood vessel supplying skeletal mus- cles constrict. C.BloodVessels supplying the intestines dilate. D. Liver cells release glucose into the blood stream. Unlike skeletal muscle, cardiac muscle is highly resistant to lactate-mediated fatigue because cardiac muscle: B.Heterotrophic with a genome stored in DNA Humans consume rather than manufacture nutrient molecules (heterotrophic), and human genes are encoded in DNA D. B-cell The production of antibodies by B-cells is part of the humoral response to antigens. Cytotoxic T-cells destroy pathogens and infected cells. Macropahges ingest and digest both non-self and dead cells. Helper T-clls help cytotoxic T-cells and other immune cells. D. Liver cells release glucose into the blood stream. Epinephrine causes liver cells to break down glycogen, which causes an in- crease in sugar in the blood stream. A. uses aerobic respiration in mitochon- dria for energy Aerobic respiration (oxidative respiration) is almost exclusively used by the heart.The byproducts of this type of res- piration are water and carbon dioxide, not lactate.
