Q: Heating a gas gives its particles more of what type of energy? Read this paragraph and choose the correct option from the provided answers: In this lesson, you read that heating a gas gives its particles more kinetic energy. As a result, its volume or pressure also increases. The opposite happens when a gas is cooled. Choices: - residual energy - electrostatic energy - nuclear energy - kinetic energy A:
kinetic energy

Q: When both momentum and kinetic energy are conserved in a closed system, the collision is called what? Read this paragraph and choose the correct option from the provided answers: For all collisions in a closed system, momentum is conserved. In some collisions in a closed system, kinetic energy is conserved. When both momentum and kinetic energy are conserved, the collision is called an elastic collision. Most collisions are inelastic because some amount of kinetic energy is converted to potential energy, usually by raising one of the objects higher (increasing gravitation PE) or by flexing the object. Any denting or other changing of shape by one of the objects will also be accompanied by a loss of kinetic energy. The only commonly seen elastic collisions are those between billiard balls or ball bearings, because these balls do not compress. And, of course, collisions between molecules are elastic if no damage is done to the molecules. Choices: - a static collision - a spontaneous collision - an accidental collision - an elastic collision A:
an elastic collision

Q: Q: Deoxyribonucleic acid (dna) is nucleotide that stores what type of information? Read this paragraph and choose the correct option from the provided answers: Nucleic Acids The nucleic acids differ in their type of pentose sugar. Deoxyribonucleic acid (DNA) is nucleotide that stores genetic information. DNA contains deoxyribose (so-called because it has one less atom of oxygen than ribose) plus one phosphate group and one nitrogen-containing base. The "choices" of base for DNA are adenine, cytosine, guanine, and thymine. Ribonucleic acid (RNA) is a ribose-containing nucleotide that helps manifest the genetic code as protein. RNA contains ribose, one phosphate group, and one nitrogen-containing base, but the "choices" of base for RNA are adenine, cytosine, guanine, and uracil. The nitrogen-containing bases adenine and guanine are classified as purines. A purine is a nitrogen-containing molecule with a double ring structure, which accommodates several nitrogen atoms. The bases cytosine, thymine (found in DNA only) and uracil (found in RNA only) are pyramidines. A pyramidine is a nitrogen-containing base with a single ring structure Bonds formed by dehydration synthesis between the pentose sugar of one nucleic acid monomer and the phosphate group of another form a "backbone," from which the components' nitrogen-containing bases protrude. In DNA, two such backbones attach at their protruding bases via hydrogen bonds. These twist to form a shape known as a double helix (Figure 2.29). The sequence of nitrogen-containing bases within a strand of DNA form the genes that act as a molecular code instructing cells in the assembly of amino acids into proteins. Humans have almost 22,000 genes in their DNA, locked up in the 46 chromosomes inside the nucleus of each cell (except red blood cells which lose their nuclei during development). These genes carry the genetic code to build one's body, and are unique for each individual except identical twins. Choices: - mononucleus - mutation - variation - genetic A:
A: genetic

Question: Q: Jellyfish belong to which phylum? Read this paragraph and choose the correct option from the provided answers: Do you know what these greenish, blob-like shapes are? Would it surprise you to learn that they are animals? They don't look anything like the animals you are probably familiar withanimals such as dogs and deer, fish and frogs. But the greenish blobs are animals nonetheless. They belong to a phylum called Cnidaria, but you may know them as jellyfish. They are very simple animals and not fish at all. Choices: - porifera - analidae - mycobacteria - cnidaria A:
Answer: cnidaria

Q: What do you call the ability to sense sound energy and perceive sound? Read this paragraph and choose the correct option from the provided answers: Hearing is the ability to sense sound energy and perceive sound. The ear is the organ that senses sound and allows us to hear. Damage to structures of the ear may cause hearing loss. Total hearing loss is called deafness. Choices: - tuning - sensory deprivation - echolocation - hearing A:
**Answer**
hearing
