Answer the following question given this paragraph: A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration. Q: What type of respiration has the advantage of releasing more energy? Choices: - kinetic - anaerobic - elastic - aerobic A:
aerobic

Answer the following question given this paragraph: So far we have focused on traits due to one gene or several genes. But what about many genes? 100s or 1000s of genes? What would happen if an entire chromosome were missing or duplicated? What if a human had only 45 chromosomes? Or 47? This real possibility is usually due to mistakes during meiosis; the chromosomes do not fully separate from each other during sperm or egg formation. Specifically, nondisjunction is the failure of replicated chromosomes to separate during anaphase II. If a zygote forms from a gamete lacking a chromosome, a viable embryo cannot be produced. Most human abnormal chromosome numbers result in the death of the developing embryo, often before a woman even realizes she is pregnant. Occasionally, a zygote with an extra chromosome can become a viable embryo and develop. Q: If a human only has 45 chromosomes it is most likely due to a mistake during what? Choices: - testis - mitosis - plexus - meiosis A:
(Answer)
meiosis

Answer the following question given this paragraph: Water is the only substance on Earth that is present in all three states of matter. This means that water is present as a solid, liquid, and gas. Earth is the only planet where water is present in all three states. All three phases may be present in a single location or in a region. The three phases are solid (ice or snow), liquid (water), and gas ( water vapor ). See ice, water, and clouds pictured below ( Figure below ). Q: What is the only substance on earth that is present in all three states of matter? Choices: - mercury - air - carbon - water A:
(A).
water
Ques:Answer the following question given this paragraph: Note Sometimes the word pure is added to substance, but this is not absolutely necessary. By definition, any single substance is pure. The smallest part of an element that maintains the identity of that element is called an atom. Atoms are extremely tiny; to make a line 1 inch long, you would need 217 million iron atoms. The smallest part of a compound that maintains the identity of that compound is called a molecule. Molecules are composed of atoms that are attached together and behave as a unit. Scientists usually work with millions and millions of atoms and molecules at a time. When a scientist is working with large numbers of atoms or molecules at a time, the scientist is studying the macroscopic view of the universe. However, scientists can also describe chemical events on the level of individual atoms or molecules, which is referred to as the microscopic viewpoint. We will see examples of Saylor URL: http://www. saylor. org/books. Q: The smallest part of an element that maintains the identity of that element is called what? Choices: - lattice - nucleus - neutron - atom A:

Ans:atom
