Answer the following question given this paragraph: The process of cellular respiration can be thought of as a highly controlled version of a combustion reaction. We do not literally burn hydrocarbons in our body, but the overall reactants and products are the same. Hydrocarbons, such as sucrose (C 12 H 22 O 11 ), are combined with oxygen in a series of enzymatic steps to product water, carbon dioxide, and energy, which is stored in the form of reactive molecules. The unbalanced chemical equation for this overall process is shown below:. Q: Hydrocarbons are combined with oxygen in a series of enzymatic steps to product water, carbon dioxide, and energy, which is stored in the form of what? Choices: - energy - dormant molecules - light - reactive molecules A:
reactive molecules

Answer the following question given this paragraph: Did you ever see a scene like the one in Figure below ? In many parts of the world, trees lose their leaves in autumn. The leaves turn color and then fall from the trees to the ground. As the leaves are falling, they have kinetic energy. While they are still attached to the trees they also have energy, but it's not because of motion. Instead, they have stored energy, called potential energy . An object has potential energy because of its position or shape. For example leaves on trees have potential energy because they could fall due to the pull of gravity. Q: What is another term for stored energy? Choices: - inertia - mechanical energy - latency - potential energy A:
(Answer)
potential energy
Ques: Answer the following question given this paragraph: In science, motion is defined as a change in position. An object's position is its location. Besides the wings of the hummingbird in the opening image, you can see other examples of motion in the Figure below . In each case, the position of something is changing. Q: In science, what is defined as a change in position? Choices: - gravity - speed - direction - motion A:
Ans: motion

Answer the following question given this paragraph: Soil is a precious resource. It allows us to grow food and the materials we use to make everything from the shirt you have on to the medicine you took this morning. Soil is made up of small pieces of rock that have broken down over hundreds, if not thousands, of years. Soil is also partly made up of the remains of plants and animals, and is home to many organisms, from earthworms to ants. But soil can be damaged by unsustainable farming practices and clear-cut logging. In this chapter, you will learn how soil forms, what it contains, and how to protect it. Q: What precious resource allows us to grow food as well as materials we turn into clothing and medicine? Choices: - petroleum - mercury - gasoline - soil A:
(A).
soil
Ques:Answer the following question given this paragraph: Centrioles are rod-like structures made of short microtubules. Though they are found in most eukaryotic cells, centrioles are absent in some plants and most fungi. Q: What is the general shape of centrioles? Choices: - spherical - arc - oval - rod A:

Ans:rod
Ques:Answer the following question given this paragraph: Human cells have 23 pairs of chromosomes, and each chromosome within a pair is called a homologous chromosome . For each of the 23 chromosome pairs, you received one chromosome from your father and one chromosome from your mother. Alleles are alternate forms of genes found on chromosomes. Homologous chromosomes have the same genes, though they may have different alleles. So, though homologous chromosomes are very similar, they are not identical. The homologous chromosomes are separated when gametes are formed. Therefore, gametes have only 23 chromosomes, not 23 pairs. Q: How many pairs of chromosomes are found in human cells? Choices: - 25 - 24 - 13 - 23 A:

Ans:
23
