Answer the following question given this paragraph: Barrier islands provide natural protection to shorelines. Storm waves strike the barrier island before they reach the shore. People also build artificial barriers, called breakwaters . Breakwaters also protect the shoreline from incoming waves. You can see an example of a breakwater in Figure below . It runs parallel to the coast like a barrier island. Q: What kind of islands provide natural protection to shorelines? Choices: - patch islands - locational islands - edge islands - barrier islands A:
barrier islands

Answer the following question given this paragraph: There are only about 6200 known species of amphibians. They are placed in three orders: frogs, salamanders, and caecilians. Table below shows a picture of an amphibian in each order. It also provides additional information about the orders. Q: What are the 3 orders of amphibians? Choices: - bees, caddisflies, antilions - monotremata, artiodactyla, rodentia - hagfish, lampreys, acanthodii - frogs, salamanders, caecilians A:
(Answer)
frogs, salamanders, caecilians
Ques: Answer the following question given this paragraph: Figure 36.20 When light strikes rhodopsin, the G-protein transducin is activated, which in turn activates phosphodiesterase. Phosphodiesterase converts cGMP to GMP, thereby closing sodium channels. As a result, the membrane becomes hyperpolarized. The hyperpolarized membrane does not release glutamate to the bipolar cell. Q: When light strikes rhodopsin, the g-protein transducin is activated, which in turn activates what? Choices: - aldosterone - photosynthesis - hydrolysis - phosphodiesterase A:
Ans: phosphodiesterase
(Q).
Answer the following question given this paragraph: Why is activation energy needed? A reaction won't occur unless atoms or molecules of reactants come together. This happens only if the particles are moving, and movement takes energy. Often, reactants have to overcome forces that push them apart. This takes energy as well. Still more energy is needed to start breaking bonds in reactants. The graphs in Figure below show the changes in energy in endothermic and exothermic reactions. Both reactions need the same amount of activation energy in order to begin. Q: What is required to break bonds in reactants? Choices: - food - gas - protein - energy A:
(A).
energy
Ques:Answer the following question given this paragraph: Diagram of a Cytomegalovirus. The capsid encloses the genetic material of the virus. The envelope which surrounds the capsid is typically made from portions of the host cell membranes (phospholipids and proteins). Not all viruses have a viral envelope. Q: What encloses the genetic material of the virus? Choices: - mitochondria - nuclei - the spindle - the capsid A:

Ans:the capsid
Ques:Answer the following question given this paragraph: The genetic code is the same in all living things. This shows that all organisms are related by descent from a common ancestor. Q: What code is the same in all living things and shows that all organisms are related by descent from a common ancestor? Choices: - descendant - biochemical - intrinsic - genetic A:

Ans:
genetic
