Q: Answer the following question given this paragraph: Acidity is measured on a pH scale. Rain that is 5.0 or less on that scale is considered acid rain. Q: Acidity is measured on what kind of scale? A:

OPTIONS:
- electromagnetic scale
- caloric scale
- pneumatic scale
- ph scale

A: ph scale

input: OPTIONS:
- typhoons
- greenhouse effect
- landslides
- floods Now, answer this question: Answer the following question given this paragraph: Floods may occur when deep snow melts quickly in the spring. More often, floods are due to heavy rainfall. Floods happen when rain falls more quickly than water can be absorbed into the ground or carried away by rivers or streams. Q: What occurs when rain falls more quickly than water can be absorbed into the ground or carried away by rivers or streams? A:
A:
output: floods

Answer the following question given this paragraph: When it comes to electric charges, opposites attract. In other words, positive and negative particles are attracted to each other. Like charges, on the other hand, repel each other, so two positive or two negative charges push apart from each other. The force of attraction or repulsion between charged particles is called electric force . It is illustrated in Figure below . The strength of electric force depends on the amount of electric charge and the distance between the charged particles. The larger the charge or the closer together the charges are, the greater is the electric force. Q: The force of attraction or repulsion between charged particles is called what? A:

OPTIONS:
- magnetic force
- cooling force
- power force
- electric force

Answer: electric force

Problem: OPTIONS:
- 4 prong
- .2 prong
- 5 prong
- 3 prong
Q: Answer the following question given this paragraph: A three-prong plug is generally used on metal appliances. The two flat prongs carry current to and from the appliance. The round prong is for safety. It connects with a wire inside the outlet that goes down into the ground. If any stray current leaks from the circuit or if there is a short circuit, the ground wire carries the current into the ground, which harmlessly absorbs it. Q: What type of plug is generally used on metal appliances? A:
Answer: 3 prong

Problem:OPTIONS:
- molecules
- fuels
- bases
- gases

Answer the following question given this paragraph: Higher pressures increase the solubility of gases. You are probably familiar with this concept as it relates to carbonated beverages. Before opening the container, the inside is pressurized, so a large amount of CO 2 is dissolved in the liquid. After opening, the pressure decreases (to the ambient pressure), so the solubility of CO 2 drops, causing it to bubble out of solution. Because they are not compressible like gases, solid and liquid solutes do not have noticeable changes in solubility at different external pressures. Q: Higher pressures increase the solubility of what? A:
****
A: gases

Problem:OPTIONS:
- inoculation
- fertilization
- reproduction
- pollination

Answer the following question given this paragraph: In order to study these characteristics, Mendel needed to control the pollination of the pea plants through artificial fertilization . Pollination occurs when the pollen from the male reproductive part of a flower, called the anthers , is transferred to the female reproductive part of a flower, called the stigma . Pea plants are self-pollinating , which means the pollen from a flower on a single plant transfers to the stigma of the same flower or another flower on the same plant. In order to avoid self-pollination, Mendel removed the anthers from the flowers on a plant. He then carefully transferred pollen from the anthers of another plant and using a small paintbrush, dusted the pollen onto the stigma of the flowers that lacked anthers. This process caused cross-pollination. The Figure below shows the location of the male and female parts of a flower. Cross-pollination occurs when pollen from one flower pollinates a flower on a different plant. In this way, Mendel controlled the characteristics that were passed onto the offspring. The product of cross-pollination is known as a hybrid. The ability to cross-pollinate pea plants allowed Mendel to study the offspring of two parents with different traits, such as a tall stem or a short stem. Q: The process of transferring pollen from the male reproductive part of a flower known as the anthers to the female reproductive part of the flower known as the stigma is referred to as what? A:
****
A:
pollination
