Answer the following question given this paragraph: The Moon is easily seen from Earth. Early astronomers used telescopes to study and map its surface. The Moon has also seen a great number of satellites, rovers, and orbiters. After all, it is relatively easy to get spacecraft to the satellite. Also, before humans could be safely sent to the Moon, many studies and experiments had to be completed. Q: What celestial object has been visited by manned spacecraft and is easily seen from earth? Choices: - venus - the Sun - Jupiter - moon A:
moon
Answer the following question given this paragraph: 16 Gregor Mendel and biological inheritance Charles Darwin1 , for all he contributed to the science of biology, never knew about the mechanism by which living things inherit traits from previous generations, or how new traits arise. As any schoolchild can tell you, this mechanism of interitance has since been found to be DNA2 , or deoxyribonucleic acid. DNA allows for stable inheritance of traits: the code in each strand of DNA is replicated precisely through the pairing of basic units along each strand. The error rate in this replication is amazingly low; not even one base pair in a million matches out of sequence. However, when even one base pair is added to a new strain of DNA in an order differently than in the parent chain, it can be the basis of a mutation. These changes in DNA sequences are the microscopic origin of changes in traits of all studied living things. Even the smallest difference in a strand of DNA can result in a change in traits that can cost the life of the organism. Mutations can produce proteins with a new or altered function. In humans, the example of Sickle cell anemia3 is commonly given as its origin is a difference of only one base pair in a section of DNA that encodes red blood cells. Individual sequences of DNA that encode for specific proteins are called genes and are the units of heredity. Each one has a set nucleotide4 , and together all of the genes (and some sequence of DNA that apparently do not code for any biologically important functions) together make up the entire chromosome5. Q: What mechanism is used by living organisms to pass along genes? Choices: - protein - digestion - chlorophyll - dna A:
dna
Q: Answer the following question given this paragraph: The transport of sediments by longshore currents is called longshore drift . Longshore drift is created in this way: Sediment is moved up the beach by an incoming wave. The wave approaches at an angle to the shore. Water then moves straight offshore. The sediment moves straight down the beach with it. The sediment is again picked up by a wave that is coming in at an angle. So longshore drift moves sediment along the shore. This zig-zag motion is pictured below ( Figure below ) and can also be seen at the link below. Q: What material is transported in a process called longshore drift? Choices: - boats - foods - grass - sediment A:
A: sediment
Question: Answer the following question given this paragraph: Q: Dry soils are relatively unproductive because plants need a sufficient quantity of liquid water to carry out what process? Choices: - contraction - shrinkage - flowering - photosynthesis A:
Answer: photosynthesis

Answer the following question given this paragraph: Nearly all fish reproduce sexually and have separate sexes. Fertilization is generally external, and most fish are oviparous. Many adults of the same species may come together in a group and release gametes into the water at the same time, which is called spawning. Fish hatch into larvae that are different from the adult form of the species. Q: What do you call it when adult fish of the same species come together in a group and release gametes into the water at the same time? Choices: - migration - schoaling - poaching - spawning A:
**Answer**
spawning
Answer the following question given this paragraph: Haumea is the third-brightest Kuiper belt object. Haumea has two moons. Haumea's odd oval shape is probably caused by its extremely rapid rotation. It rotates in just less than 4 hours! Like other Kuiper belt objects, Haumea is covered by ice. Its density is similar to Earth's Moon, at 2.6 3.3 g/cm 3 . This means that most of Haumea is rocky. Q: Haumea, which is the third brightest kuiper belt object has an odd oval shape which is probably caused by what? Choices: - unusually rapid rotation - particularly rapid rotation - Slow rotation - extremely rapid rotation A:
extremely rapid rotation
