Answer the following question given this paragraph: Electric generators convert mechanical energy to electric energy. The generator consists of some number of wire loops wrapped around an iron core and placed in a strong magnetic field. The loops of wire and the iron core are called the armature . The armature is mounted so that it can rotate freely inside the magnetic field. Mechanical energy is used to spin the armature in the field so that the wire loops cut across the field and produce electric current. The of this current is calculated by . Q: Electric generators convert what type of energy to electric energy? Choices: - electromagnetic energy - thermodynamic energy - fluid energy - mechanical energy A:
mechanical energy

Answer the following question given this paragraph: Q: Where are the viral enzyme and genome packaged inside? Choices: - pollen grains - ribosomes - mitochondria - viral capsid A:
(Answer)
viral capsid
Ques: Answer the following question given this paragraph: The DNA double helix. The two sides are the sugar-phosphate backbones, composed of alternating phosphate groups and deoxyribose sugars. The nitrogenous bases face the center of the double helix. As the base-pairing rules tell us, A always pairs with T, and G always pairs with C. Q: Which structure includes sugar-phosphate "backbones", composed of alternating phosphate groups and deoxyribose sugars, and nitrogenous bases? Choices: - molecule double helix - mulecular triplex - dna triple helix - dna double helix A:
Ans: dna double helix
(Q).
Answer the following question given this paragraph: The haploid gametophyte produces the gametes, or sperm and egg, by mitosis. Remember, gametes are haploid, having one set of chromosomes. Q: By what process does the haploid gametophyte produce the gametes? Choices: - meiosis - angiogenesis - Spermatogenesis - mitosis A:
(A).
mitosis
Ques:Answer the following question given this paragraph: Electron affinity is a measure of the energy released when an extra electron is added to an atom. Q: What is the measure of the energy released when an extra electron is added to an atom? Choices: - mass affinity - neutron affinity - volume affinity - electron affinity A:

Ans:electron affinity
Ques:Answer the following question given this paragraph: Glial Cells of the CNS One cell providing support to neurons of the CNS is the astrocyte, so named because it appears to be star-shaped under the microscope (astro- = "star"). Astrocytes have many processes extending from their main cell body (not axons or dendrites like neurons, just cell extensions). Those processes extend to interact with neurons, blood vessels, or the connective tissue covering the CNS that is called the pia mater (Figure 12.11). Generally, they are supporting cells for the neurons in the central nervous system. Some ways in which they support neurons in the central nervous system are by maintaining the concentration of chemicals in the extracellular space, removing excess signaling molecules, reacting to tissue damage, and contributing to the blood-brain barrier (BBB). The blood-brain barrier is a physiological barrier that keeps many. Q: Contributing to the blood-brain barrier is one of the jobs of glial cells, which support neurons in what system? Choices: - peripheral nervous system - circulatory system - digestive system - central nervous system A:

Ans:
central nervous system
