Q: Answer the following question given this paragraph: Q: Overproduction of offspring, combined with limited resources, results in what? A:

OPTIONS:
- continuation
- contention
- concentration
- competition

A: competition

input: OPTIONS:
- floors
- vegetation
- curtains
- insulation Now, answer this question: Answer the following question given this paragraph: Solar energy is used to heat homes and water, and to make electricity. Scientists and engineers have many ways to get energy from the Sun ( Figure above ). One is by using solar cells. Solar cells are devices that turn sunlight directly into electricity. Lots of solar cells make up an individual solar panel. You may have seen solar panels on roof tops. The Sun's heat can also be trapped in your home by using south facing windows and good insulation. Q: The sun's heat can also be trapped in your home by using south facing windows and good what? A:
A:
output: insulation

Answer the following question given this paragraph: Oil (red) is found in the porous rock layer (yellow) and trapped by the impermeable layer (brown). The folded structure has allowed the oil to pool so a well can be drilled into the reservoir. Q: Oil is found in the porous rock layer and trapped by the what? A:

OPTIONS:
- - crystalline layer
- mantle
- impermeable layer

Answer: impermeable layer

Problem: OPTIONS:
- fish
- zooplankton
- algea
- phytoplankton
Q: Answer the following question given this paragraph: Phytoplankton are the primary producers in the ocean. They form the base of most marine food chains. Q: What are the primary producers in the ocean? A:
Answer: phytoplankton

Problem:OPTIONS:
- autoimmune disease
- heart disease
- colds
- cancer

Answer the following question given this paragraph: Oncogenes are genes involved in cancer formation. Q: Oncogenes are involved in the formation of what disease? A:
****
A: cancer

Problem:OPTIONS:
- shell electrons
- outer electrons
- positive electrons
- valence electrons

Answer the following question given this paragraph: The electrons in the outer energy level of an atom are called valence electrons . It is valence electrons that are potentially involved in chemical reactions. The number of valence electrons determines an element's reactivity, or how likely the element is to react with other elements. The number of valence electrons also determines whether the element can conduct electric current. That's because electric current is the flow of electrons. Table below shows how these properties vary in elements from each class. Q: What are electrons in the outer energy level of an atom called? A:
****
A:
valence electrons
