Answer the following question given this paragraph: Saturated fatty acids have only single bonds between carbon atoms. As a result, the carbon atoms are bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogens. Saturated fatty acids are found in fats. Q: Carbon atoms are bonded to as many hydrogen atoms as possible in what type of fatty acids? Choices: - super - unsaturated - oily - saturated A:
saturated

Ques: Answer the following question given this paragraph: The fuel that burns in a combustion reaction contains compounds called hydrocarbons. Hydrocarbons are compounds that contain only carbon (C) and hydrogen (H). The charcoal pictured in the Figure above consists of hydrocarbons. So do fossil fuels such as natural gas. Natural gas is a fuel that is commonly used in home furnaces and gas stoves. The main component of natural gas is the hydrocarbon called methane (CH 4 ). You can see a methane flame in the Figure below . The combustion of methane is represented by the equation:. Q: What is the name for compounds that contain only carbon and hydrogen? Choices: - particles - carbohydrates - carbides - hydrocarbons A:
Ans: hydrocarbons
(Q).
Answer the following question given this paragraph: Flatworms reflect several major evolutionary advances in invertebrates. They have three embryonic cell layers, including mesoderm. The mesoderm layer allows them to develop organ systems. For example, they have muscular and excretory systems. The muscular system allows them to move from place to place over solid surfaces. The excretory system lets them maintain a proper balance of water and salts. Flatworms also show cephalization and bilateral symmetry. Q: What system lets flatworms maintain a proper balance of water and salts? Choices: - homeostasis - nervous - digestive - excretory A:
(A).
excretory
Ques:Answer the following question given this paragraph: When a sperm penetrates the egg, it triggers the egg to complete meiosis. The sperm also undergoes changes. Its tail falls off, and its nucleus fuses with the nucleus of the egg. The resulting cell, called a zygote, contains all the chromosomes needed for a new human organism. Half the chromosomes come from the egg and half from the sperm. Q: When a sperm penetrates the egg, it triggers the egg to complete what? Choices: - mutations - fertilization - lesions - meiosis A:

Ans:meiosis
Answer the following question given this paragraph: Carbohydrates include sugars, starches, and fiber. Sugars and starches are used by the body for energy. One gram of carbohydrates provides 4 Calories of energy. Fiber, which is found in plant foods, cannot be digested but is needed for good health. Simple carbohydrates are small carbohydrates found in foods such as fruits and milk. These carbohydrates include lactose, fructose and glucose. Complex carbohydrates are much larger molecules. Starch, which is a complex carbohydrate found in vegetables and grains, is made of thousands of glucose units bonded together. Q: What category of food includes sugars, starches and fibers? Choices: - enzymes - proteins - alcohols - carbohydrates A:
carbohydrates
