Answer the following question given this paragraph: The thymus is found behind the sternum. The thymus produces hormones referred to as thymosins, which contribute to the development of the immune response in infants. Adipose tissue, or fat tissue, produces the hormone leptin in response to food intake. Leptin produces a feeling of satiety after eating, reducing the urge for further eating. Q: What produces hormones referred to as thymosins, which contribute to the development of the immune response in infants? Choices: - pancreas - heart - receptors - thymus A:
(Answer)
thymus

You can read about both types of cells and how they work below. Q: Chemical and solar cells are devices that change chemical or light energy to what? Choices: - cellular - occurring energy - temperature energy - electrical energy A:
Ans: electrical energy
(Q).
Answer the following question given this paragraph: Genes play an important part in influencing phenotype, but genes are not the only influence. Environmental conditions, such as temperature and availability of nutrients can affect phenotypes. For example, temperature affects coat color in Siamese cats. Q: Temperature can affect what attribute of a siamese cat's coat? Choices: - weight - chemical makeup - density - color A:
(A).
color

Ques:Answer the following question given this paragraph: Heterotrophs are organisms incapable of photosynthesis that must therefore obtain energy and carbon from food by consuming other organisms. The Greek roots of the word heterotroph mean "other" (hetero) "feeder" (troph), meaning that their food comes from other organisms. Even if the food organism is another animal, this food traces its origins back to autotrophs and the process of photosynthesis. Humans are heterotrophs, as are all animals. Heterotrophs depend on autotrophs, either directly or indirectly. Deer and wolves are heterotrophs. A deer obtains energy by eating plants. A wolf eating a deer obtains energy that originally came from the plants eaten by that deer. The energy in the plant came from photosynthesis, and therefore it is the only autotroph in this example (Figure 5.3). Using this reasoning, all food eaten by humans also links back to autotrophs that carry out photosynthesis. Q: Organisms incapable of photosynthesis that must therefore obtain energy and carbon from food by consuming other organisms are called what? Choices: - photoautotrophs - autotrophs - chemoautotrophs - heterotrophs A:

Ans:
heterotrophs
