Answer the following question given this paragraph: Secretory Vesicles contain materials that are to be excreted from the cell, such as wastes or hormones . Secretory vesicles include synaptic vesicles and vesicles in endocrine tissues. Synaptic vesicles store neurotransmitters. They are located at presynaptic terminals in neurons. When a signal reaches the end of an axon, the synaptic vesicles fuse with the cell membrane and release the neurotransmitter. The neurotransmitter crosses the synaptic junction, and binds to a receptor on the next cell. Some cells also produce molecules, such as hormones produced by endocrine tissues, needed by other cells. These molecules are stored in secretory vesicles and released when needed. Secretory vesicles also hold enzymes needed to make extracellular structures, such as the extracellular matrix of animal cells. Q: What vesicles store neurotransmitters? Choices: - hydrophobic - dendritic - Golgi apparatus - synaptic A:
synaptic

Answer the following question given this paragraph: Introduction Virtually every task performed by living organisms requires energy. Energy is needed to perform heavy labor and exercise, but humans also use energy while thinking, and even during sleep. In fact, the living cells of every organism constantly use energy. Nutrients and other molecules are imported into the cell, metabolized (broken down) and possibly synthesized into new molecules, modified if needed, transported around the cell, and possibly distributed to the entire organism. For example, the large proteins that make up muscles are built from smaller molecules imported from dietary amino acids. Complex carbohydrates are broken down into simple sugars that the cell uses for energy. Just as energy is required to both build and demolish a building, energy is required for the synthesis and breakdown of molecules as well as the transport of molecules into and out of cells. In addition, processes such as ingesting and breaking down pathogenic bacteria and viruses, exporting wastes and toxins, and movement of the cell require energy. From where, and in what form, does this energy come? How do living cells obtain energy, and how do they use it? This chapter will discuss different forms of energy and the physical laws that govern energy transfer. This chapter will also describe how cells use energy and replenish it, and how chemical reactions in the cell are performed with great efficiency. Q: Virtually every task performed by living organisms requires this? Choices: - solids - mineral - metals - energy A:
(Answer)
energy
Ques: Answer the following question given this paragraph: Cephalopods include the octopus and squid. They have a prominent head and a well-developed brain. Typically the foot has been modified into a set of arms or tentacles. Members of this class can change color. They can also change texture and body shape, and, and if those camouflage techniques don't work, they can still "disappear" in a cloud of ink. Cephalopods have three hearts that pump blue blood, they're jet powered by their muscular foot, and they're found in all oceans of the world. Cephalopods are thought to be the most intelligent of invertebrates. They have eyes and other senses that rival those of humans. Many cephalopods are active and efficient predators. What features do you think allows for this?. Q: Cephalopods have three hearts that pump blood of what color? Choices: - purple - Green - Red - blue A:
Ans: blue

Answer the following question given this paragraph: Charging an object by touching it with another charged object is called charging by conduction. By bringing a charged object into contact with an uncharged object, some electrons will migrate to even out the charge on both objects. Charging by conduction gives the previously uncharged object a permanent charge. An uncharged object can also be charged using a method called charging by induction . This process allows a change in charge without actually touching the charged and uncharged objects to each other. Imagine a negatively charged rod held near the knob, but not touching. If we place a finger on the knob, some of the electrons will escape into our body, instead of down the stem and into the leaves. When both our finger and the negatively charged rod are removed, the previously uncharged electroscope now has a slight positive charge. It was charged by induction. Notice that charging by induction causes the newly charged object to have the opposite charge as the originally charged object, while charging by conduction gives them both the same charge. Q: What is the name for the process of charging an object by touching it with another charged object? Choices: - charging by connection - charging by convection - charging by transfer - charging by conduction A:
(A).
charging by conduction
Ques:Answer the following question given this paragraph: The peripheral nervous system consists of all the nervous tissue that lies outside the central nervous system. It is connected to the central nervous system by nerves. Q: What connects the peripheral nervous system to the central nervous system? Choices: - fibers - wires - veins - nerves A:

Ans:nerves
Answer the following question given this paragraph: Hyphae : These are thread-like strands which interconnect and bunch up into a mycelium ( Figure below ). Ever see mold on a damp wall or on old bread? The things that you are seeing are really mycelia. The hyphae and mycelia help the fungi absorb nutrients from other organisms. Most of the mycelium is hidden from view deep within the fungal food source, such as rotting matter in the soil, leaf litter, rotting wood, or dead animals. Fungi produce enzymes to digest cellulose and various other materials found in rotting matter, helping with the decaying process. Q: What helps fungus digest cellulose and other materials found in rotting matter? Choices: - carbohydrates - hormones - soil - enzymes A:
enzymes
