Answer the following question given this paragraph: Muscular dystrophy is a term encompassing a variety of muscle wasting diseases. The most common type, Duchenne Muscular Dystrophy (DMD) , affects cardiac and skeletal muscle, as well as some mental functions. DMD is caused by a defective gene for dystrophin, a protein prevalent in skeletal and cardiac muscles. DMD is an X-linked recessive disorder occurring in 1 in 3,500 male newborns. Because DMD is X-linked, no females are affected. Most affected individuals die before their 20th birthday. Daughters of female carriers of the mutant allele have a 50% chance of also being carriers. Q: What type of disease is muscular dystrophy? Choices: - contagious disease - mutation - infectious disease - a wasting disease A:
a wasting disease
Answer the following question given this paragraph: The valence shell is the outermost occupied shell of electrons in an atom. This shell holds the valence electrons, which are the electrons that are involved in bonding and shown in a Lewis structure. Valence-shell electron pair repulsion theory , or VSEPR theory, states that a molecule will adjust its shape so that the valence electron pairs stay as far apart from each other as possible. This makes sense, based on the fact that negatively charged electrons repel one another. We will systematically classify molecules according to the number of bonding pairs of electrons and the number of nonbonding or lone pairs around the central atom. For the purposes of the VSEPR model, a double or triple bond is no different in terms of repulsion than a single bond. We will begin by examining molecules in which the central atom does not have any lone pairs. Q: What is the outermost occupied shell of electrons in an atom. Choices: - Inner Shell - radiative shell - modular shell - valence shell A:
valence shell
Q: Answer the following question given this paragraph: Figure 16.5 (a) Digestion of food begins in the mouth. (b) Food is masticated by teeth and moistened by saliva secreted from the salivary glands. Enzymes in the saliva begin to digest starches and fats. With the help of the tongue, the resulting bolus is moved into the esophagus by swallowing. (credit: modification of work by Mariana Ruiz Villareal). Q: Enzymes in saliva help bread down and digest what? Choices: - starches and water - water and fiber - fiber and minerals - starches and fats A:
A: starches and fats
Question: Answer the following question given this paragraph: Figure 12.25 Graded Potentials Graded potentials are temporary changes in the membrane voltage, the characteristics of which depend on the size of the stimulus. Some types of stimuli cause depolarization of the membrane, whereas others cause hyperpolarization. It depends on the specific ion channels that are activated in the cell membrane. Q: Graded potentials are temporary changes in what, the characteristics of which depend on the size of the stimuli? Choices: - components voltage - organic voltage - organism voltage - membrane voltage A:
Answer: membrane voltage

Answer the following question given this paragraph: Sea otters are known for being playful and frisky. They are serious eaters, however! A major part of a sea otter's diet are echinoderms, such as sea urchins. They manage to eat the soft part of the sea urchins while avoiding the huge sea urchin spines. Q: What type of animals are known for being playful and frisky? Choices: - cows - snakes - giant tortoises - sea otters A:
**Answer**
sea otters

Answer the following question given this paragraph: Ocean water also absorbs gases from the atmosphere. The most important are oxygen and carbon dioxide. Oxygen is needed by living things in the oceans. Much of the carbon dioxide sinks to the bottom of the seas. Carbon dioxide is a major cause of global warming. By absorbing carbon dioxide, the oceans help control global warming. Q: How do oceans help control global warming? Choices: - releasing oxygen - reflecting light - Cooling air - absorbing carbon dioxide A:
(Answer)
absorbing carbon dioxide
