Answer the following question given this paragraph: The mitochondria are the powerhouses of the cell. Mitochondria are the organelles where cellular energy is produced, providing the energy needed to power chemical reactions. This process, known as cellular respiration , produces energy is in the form of ATP (adenosine triphosphate). Cells that use a lot of energy may have thousands of mitochondria. Q: Called the powerhouses of the cell, what organelles are the site of cellular energy production? Choices: - nucleus - mitosis - cell wall - mitochondria A:
mitochondria

Answer the following question given this paragraph: Giant steps in science may occur if a scientist introduces a major new idea. For example, in 1666, Isaac Newton introduced the idea that gravity is universal. People had long known that things fall to the ground because they are attracted by Earth. But Newton proposed that everything in the universe exerts a force of attraction on everything else. This idea is known as Newton's law of universal gravitation. Q: Who proposed that everything in the universe exerts a force of attraction on everything else? Choices: - bell - einstein - wilson - newton A:
(Answer)
newton
Ques: Answer the following question given this paragraph: Most prokaryotes get both energy and carbon from other living things. Many of them are decomposers. They break down wastes and remains of dead organisms. In this way, they help to recycle carbon and nitrogen through ecosystems. Q: By breaking down wastes and remains of dead organisms, decomposers perform what function in an ecosystem? Choices: - reproduction - symbiosis - collecting - recycling A:
Ans: recycling
(Q).
Answer the following question given this paragraph: All living cells have certain things in common. Besides having the basic parts described above, all cells can perform the same basic functions. For example, all cells can use energy, respond to their environment, and reproduce. However, cells may also have special functions. Multicellular organisms such as you have many different types of specialized cells. Each specialized cell has a particular job. Cells with special functions generally have a shape that suits them for that job. Q: What kind of organisms have many different types of specialized cells with particular jobs? Choices: - monocellular - crude - intricate - multicellular A:
(A).
multicellular
Ques:Answer the following question given this paragraph: high proportion of amino acids in the protein have nonpolar side chains. The term hydrophobic interaction is often misused as a synonym for dispersion forces. Hydrophobic interactions arise because water molecules engage in hydrogen bonding with other water molecules (or groups in proteins capable of hydrogen bonding). Saylor URL: http://www. saylor. org/books. Q: Hydrophobic interactions arise because water molecules engage in what type of bonding with other water molecules? Choices: - aquatic bonding - oxygen bonding - helium bonding - hydrogen bonding A:

Ans:hydrogen bonding
Ques:Answer the following question given this paragraph: The term carbohydrate comes from the fact that the majority contain carbon, hydrogen, and oxygen in a ratio of 1:2:1, making for an empirical formula of CH 2 O. This is somewhat misleading because the molecules are not actually hydrates of carbon at all. Carbohydrates are monomers and polymers of aldehydes and ketones that have multiple hydroxyl groups attached. Q: What contains carbon, hydrogen, and oxygen in a ratio of 1:2:1? Choices: - helium - sodium - magnesium - carbohydrate A:

Ans:
carbohydrate
