Q: Q: The calvin cycle is the fancy name for the metabolic pathway that builds what? Read this paragraph and choose the correct option from the provided answers: 13.2.1 The Detailed Dark Reactions What the Dark Reactions Do: The dark reactions build sugar from carbon dioxide gas (CO2), water (H2O), and energy from ATP molecules that were charged up during the light reactions. The dark reactions occur in the stroma of a chloroplast. Dark reactions usually occur in the light, but they don't have to. They'll occur in the dark until the chloroplast's supply of ATP runs out (usually about 30 seconds). The Calvin Cycle: The Calvin Cycle is the fancy name for the metabolic pathway that builds sugar. This means that it involves a whole lot of chemical reactions, and it uses a lot of different enzymes to catalyze the reactions. Carbon dioxide gas is stable, therefore the bonds that hold the carbon and oxygen atoms are strong. Therefore it takes a lot of energy to break the bonds and separate the carbon atoms from the oxygen atoms. The energy needed to do this comes from ATP molecules. When inorganic carbon (like from CO2) is being added to an organic molecule (such as sugar), this is called carbon fixation. It takes 2 complete turns of the Calvin Cycle to make a glucose molecule. Some portions of this text is based on notes very generously donated by Paul Doerder, Ph. , of the Cleveland State University. The detailed portions are not provided by Dr. Doerder. How cells divide. Choices: - proteins - fats - carbohydrates - sugar A:
A: sugar

Q: Q: What pair of tubes that extends toward the ovaries features a fringelike structure that sweeps eggs inside? Read this paragraph and choose the correct option from the provided answers: Extending from the upper corners of the uterus are the two fallopian tubes. Each tube reaches (but is not attached to) one of the ovaries. The ovary end of the tube has a fringelike structure that moves in waves. The motion sweeps eggs from the ovary into the tube. Choices: - golgi apparatus - ovarian tubes - vas deferens - fallopian tubes A:
A: fallopian tubes

Q: Q: Niche refers to the role a species plays in what? Read this paragraph and choose the correct option from the provided answers: The role a species plays in the ecosystem is called its niche. Choices: - the habitat - reproduction - migration - the ecosystem A:
A: the ecosystem

Q: Q: In what organ is food remains turned into solid waste for excretion? Read this paragraph and choose the correct option from the provided answers: Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled. In the large intestine, the remains of food are turned into solid waste for excretion. How is waste other than carbon dioxide removed from the blood? That is the role of the kidneys. Choices: - non-transverse intenstine - large tissue - large metabolism - large intestine A:
A: large intestine
