Answer the following question given this paragraph: Gap genes control the expression of other genes within specific regions of cells in the developing organism. This allows specific genes to be expressed in certain cells at the appropriate stage of development. Q: What is the term for genes that control the expression of other genes within specific regions of cells in the developing organism? Choices: - expression genes - age genes - data genes - gap genes A:
gap genes

Question: Answer the following question given this paragraph: When bacteria are destroyed by leukocytes, pyrogens are released into the blood. Pyrogens reset the body's thermostat to a higher temperature, resulting in fever. How might pyrogens cause the body temperature to rise?. Q: When bacteria are destroyed by leukocytes, what are released into the blood? Choices: - carcinogens - proteins - sporozoans - pyrogens A:
Answer: pyrogens

Answer the following question given this paragraph: The structure of heme (Figure 19.29), the iron-containing complex in hemoglobin, is very similar to that in chlorophyll. In hemoglobin, the red heme complex is bonded to a large protein molecule (globin) by the attachment of the protein to the heme ligand. Oxygen molecules are transported by hemoglobin in the blood by being bound to the iron center. When the hemoglobin loses its oxygen, the color changes to a bluish red. Hemoglobin will only transport oxygen if the iron is Fe2+; oxidation of the iron to Fe3+ prevents oxygen transport. Q: When the hemoglobin loses its oxygen, it changes to what color? Choices: - purple red - grayish red - light pink - bluish red A:
**Answer**
bluish red

Answer the following question given this paragraph: an identical particle that has been ejected from a heavier nucleus. There are six fundamentally different kinds of nuclear decay reactions, and each releases a different kind of particle or energy. The essential features of each reaction are shown in Figure 20.4 "Common Modes of Nuclear Decay". The most common are alphaand beta decay and gamma emission, but the others are essential to an understanding of nuclear decay reactions. Figure 20.4 Common Modes of Nuclear Decay. Q: There are six fundamentally different kinds of nuclear decay reactions, and each releases a different kind of particle or what? Choices: - protein - mineral - mass - energy A:
**Answer**
energy
