Answer the following question given this paragraph: The cell membrane is made up of a phospholipid bilayer, two layers of phospholipid molecules. Notice the polar head group of the phospholipid is attached to the phosphate, and the tails are two fatty acid chains. The head group and tails are attached by a glycerol backbone. Q: What basic cell structure is made up of a phospholipid bilayer and two layers of phospholipid molecules? Choices: - cell cartilage - nucleus - mitochondria - cell membrane A:
cell membrane

Answer the following question given this paragraph: The image above is one type of electrical fuse. This fuse has a specially designed wire inside glass housing. The wire inside the glass is made of a particular metal and with a particular thickness to give the wire an exact resistance. This resistance will allow passage of normal current plus a marginal percentage more. If, however, the current exceeds the allowed value, the wire in the fuse will heat and melt, thus interrupting current flow through the circuit. The fuse wire is placed in the glass housing and a fuse mount to insulate the melting wire from its surroundings. Any unintended increase in current, such as short circuits, overloading, mismatched loads, or device failure will cause the fuse to burn out protecting the other parts of the circuit from overheating and further damage. Q: What happens to the wire in a fuse if it's current rating is exceed? Choices: - disappears - ignites - sparks - it melts A:
(Answer)
it melts
Ques: Answer the following question given this paragraph: One example of a gap gene is the Kruppel gene, which regulates the activity of a number of other genes. Kruppel literally means "cripple" in German, named for the crippled appearance of mutant larva. Gap genes are defined by the effect of a mutation in that gene, and Kruppel is one such effect. Other gap genes are known as tailless and knirps (a "squirt or whippersnapper"). Gap genes encode transcription factors which directly effect the expression of additional genes involved in embryo segmentation, called the pair-rule genes . Pair-rule genes are expressed in alternating segments within the developing embryo. Pair-rule genes have very creative names, such as even-skipped, hairy, odd-skipped, odd-paired, sloppy paired and fushi tarazu , which is Japanese for "few segments. " See My favorite silly gene names at http://www. itsokaytobesmart. com/post/82318778810/funny-gene-names for a list of other interesting gene names. Q: Gap genes are defined by the effect of what in that gene? Choices: - infection - radiation - modification - mutation A:
Ans: mutation

Ques:Answer the following question given this paragraph: The Voyager 1 spacecraft visited Saturn in 1980. Voyager 2 followed in 1981. These probes sent back detailed pictures of Saturn, its rings, and some of its moons ( Figure below ). From the Voyager data, we learned what Saturn's rings are made of. They are particles of water and ice with a little bit of dust. There are several gaps in the rings. These gaps were cleared out by moons within the rings. Gravity attracts dust and gas to the moon from the ring. This leaves a gap in the rings. Other gaps in the rings are caused by the competing forces of Saturn and its moons outside the rings. Q: What planet did the voyager 1 spacecraft visit in 1980? Choices: - venus - mars - jupiter - saturn A:

Ans:saturn
Ques:Answer the following question given this paragraph: Many ecosystems have changed because of human actions. The human species is responsible for a range of environmental problems. Q: What is the main function of the cardiovascular system? Choices: - implanatation - digestion - respiration - to transport A:

Ans:
to transport
