Answer the following question given this paragraph: Mangrove roots are like stilts, allowing mangrove trees to rise high above the water. The trunk and leaves are above water even at high tide. A bloodroot plant uses food stored over the winter to grow flowers in the early spring. Q: Why do mangrove trees rise high above the water? which characteristic help them to do so? Choices: - heavy roots - fat roots - no roots - stilt like roots A:
stilt like roots

Answer the following question given this paragraph: Carbohydrates are biochemical compounds that include sugars, starches, and cellulose. They contain oxygen in addition to carbon and hydrogen. Organisms use carbohydrates mainly for energy. Q: Sugars, starches, and cellulose are examples of what biochemical compounds that organisms use for energy? Choices: - calories - prokaryotes - proteins - carbohydrates A:
(Answer)
carbohydrates
Ques: Answer the following question given this paragraph: The organ that we use to hear sound is the ear. Almost all the structures in the ear are needed for this purpose. Together, they gather and amplify sound waves and change their energy to electrical signals. The electrical signals travel to the brain, which interprets them as sound. Q: What organ do we use to hear sound? Choices: - eye - antennae - amplifier - the ear A:
Ans: the ear

Answer the following question given this paragraph: The Pressure of a Mixture of Gases: Dalton's Law Unless they chemically react with each other, the individual gases in a mixture of gases do not affect each other's pressure. Each individual gas in a mixture exerts the same pressure that it would exert if it present alone in the container (Figure 9.20). The pressure exerted by each individual gas in a mixture is called its partial pressure. This observation is summarized by Dalton's law of partial pressures: The total pressure of a mixture of ideal gases is equal to the sum of the partial pressures of the component gases: P Total = P A + P B + P C + . = i P i In the equation PTotal is the total pressure of a mixture of gases, PA is the partial pressure of gas A; PB is the partial pressure of gas B; PC is the partial pressure of gas C; and so on. Q: According to dalton's law, unless they chemically react with each other, individual gases in a mixture of gases do not affect each other's what? Choices: - mass - weight - density - pressure A:
(A).
pressure
Ques:Answer the following question given this paragraph: Weather makes life interesting. Weather also causes weathering. Weathering is the slow wearing down of rocks on Earth's surface. Wind-blown sand scours rocks like sandpaper. Glaciers of ice scrape across rock surfaces like a file. Even gentle rain may seep into rocks and slowly dissolve them. If the water freezes, it expands. This eventually causes the rocks to crack. Without the atmosphere, none of this weathering would happen. Rocks at the surface would be pristine and unaltered. Q: What is the term for the slow wearing down of rocks on earth's surface? Choices: - slipping - evaporation - experiencing - weathering A:

Ans:weathering
Answer the following question given this paragraph: Sperm are released from the body during ejaculation. Ejaculation occurs when muscle contractions propel sperm from the epididymes. The sperm are forced through the ducts and out of the body through the urethra. As sperm travel through the ducts, they mix with fluids from the glands to form semen. Hundreds of millions of sperm are released with each ejaculation. Q: Ejaculation occurs when muscle contractions propel sperm from where? Choices: - cervix - penis - urinary track - epididymes A:
epididymes
