Answer the following question given this paragraph: After a heavy rain, you may find puddles of water standing in low spots. The same principle explains why water collects in ponds and lakes. Water travels downhill, so a depression in the ground fills with standing water. A pond is a small body of standing water. A lake is a large body of standing water. Most lakes have freshwater, but a few are salty. The Great Salt Lake in Utah is an example of a saltwater lake. Q: In which direction does water travel? Choices: - backwards - northwest - uphill - downhill A:
downhill

Answer the following question given this paragraph: Raising the temperature of a chemical reaction usually results in a higher rate of reaction. When the reactant particles are heated, they move faster and faster. This results in a greater frequency of collisions. A more important effect of the temperature increase is that the collisions occur with a greater force and are thus more likely to surmount the activation energy barrier and go on to form products. Increasing the temperature of a reaction increases the number of effective collisions between reacting particles, so the reaction rate increases. Q: Higher temperatures increase the rate of reaction in a lot of chemical reactions because they increase the frequency of what interaction between reactant particles? Choices: - electric - explosions - waves - collisions A:
(Answer)
collisions
Ques: Answer the following question given this paragraph: Organisms that have a diploid life cycle spend the majority of their lives as diploid adults. All diploid adults inherit half of their DNA from each parent. When they are ready to reproduce, diploid reproductive cells undergo meiosis and produce haploid gametes. These gametes then fuse through fertilization and produce a diploid zygote, which immediately enters G 1 of the cell cycle. Next, the zygote's DNA is replicated. Finally, the processes of mitosis and cytokinesis produce two genetically identical diploid cells. Through repeated rounds of growth and division, this organism becomes a diploid adult and the cycle continues. This is the life cycle of humans. Q: What is the series of changes in the life of an organism? Choices: - insect metamorphosis - evolution - circle of life - life cycle A:
Ans: life cycle
(Q).
Answer the following question given this paragraph: Q: Poetically speaking, nature reserves are islands of what, in a sea of habitat degraded by human activity? Choices: - refuge - habitats - ecosystem - biodiversity A:
(A).
biodiversity
Ques:Answer the following question given this paragraph: The pupil is an opening in the front of the eye. It looks black because it doesn't reflect any light. All the light passes through it instead. The pupil controls the amount of light that enters the eye. It automatically gets bigger or smaller to let more or less light in as needed. Q: What is the opening in the front of the eye called? Choices: - lens - cornea - iris - pupil A:

Ans:pupil
Question: Answer the following question given this paragraph: Earthquakes are used to identify plate boundaries ( Figure below ). When earthquake locations are put on a map, they outline the plates . The movements of the plates are called plate tectonics. Q: What is the movement of plates called? Choices: - fracking - migration - volcanic activity - plate tectonics A:
Answer:
plate tectonics
