Answer the following question given this paragraph: The fetal stage begins about two months after fertilization and continues until birth. During this stage, organs continue to develop, and the fetus grows in size. Q: The fetal stage begins about how long after fertilization? Choices: - one month - four months - three months - two months A:
two months

Answer the following question given this paragraph: Convergent plate boundaries also produce strong, deadly earthquakes. Earthquakes mark the motions of colliding plates and the locations where plates plunge into the mantle. These earthquakes can be shallow, intermediate or deep focus. Q: Earthquakes mark the motions of colliding plates and the locations where plates plunge into what? Choices: - the mesosphere - the crust - the core - the mantle A:
(Answer)
the mantle
Ques: Answer the following question given this paragraph: Figure 10.1 The mention of a tornado conjures up images of raw destructive power. Tornadoes blow houses away as if they were made of paper and have been known to pierce tree trunks with pieces of straw. They descend from clouds in funnel-like shapes that spin violently, particularly at the bottom where they are most narrow, producing winds as high as 500 km/h. (credit: Daphne Zaras, U. National Oceanic and Atmospheric Administration). Q: What descend from clouds in funnel-like shapes that spin violently, producing powerful winds? Choices: - currents - rains - hurricanes - tornadoes A:
Ans: tornadoes
(Q).
Answer the following question given this paragraph: RNA consists of just one chain of nucleotides. DNA consists of two chains. Nitrogen bases on the two chains of DNA form hydrogen bonds with each other. Hydrogen bonds are relatively weak bonds that form between a positively charged hydrogen atom in one molecule and a negatively charged atom in another molecule. Hydrogen bonds form only between adenine and thymine, and between guanine and cytosine. These bonds hold the two chains together and give DNA is characteristic double helix, or spiral, shape. Q: What has two chains of nucleotides, one more than rna? Choices: - gna - fna - mna - dna A:
(A).
dna
Ques:Answer the following question given this paragraph: In general, for an electric charge to move from one position to another, there must be a difference in electric potential energy between the two positions. The difference in electric potential energy is called potential difference, or voltage . Voltage is measured in an SI unit called the volt (V). For example, the terminals of the car battery in Figure below have a potential difference of 12 volts. This difference in voltage results in a spontaneous flow of charges, or electric current. Q: The difference in electric potential energy which allows for an electric charge to move from one position to another is measured by what si unit? Choices: - ohm - joule - meter - volt A:

Ans:volt
Ques:Answer the following question given this paragraph: Neurons are classified based on the direction in which they carry nerve impulses. Q: Neurons are classified based on the direction in which they carry what? Choices: - metabolism impulses - energy - neurotransmitters - nerve impulses A:

Ans:
nerve impulses
