Answer the following question given this paragraph: Energy is the ability to do work. When work is done, energy is transferred from one object to another. Energy can exist in different forms, such as electrical and chemical energy. Most forms of energy can also be classified as kinetic or potential energy. Q: Kinetic and potential are two forms of what? Choices: - pressure - fuel - exercise - energy A:
energy

Answer the following question given this paragraph: Eukaryotic cells also contain other organelles besides the nucleus. An organelle is a structure within the cytoplasm that performs a specific job in the cell. Organelles called mitochondria, for example, provide energy to the cell, and organelles called vacuoles store substances in the cell. Organelles allow eukaryotic cells to carry out more functions than prokaryotic cells can. Q: What is the term for a structure within the cytoplasm that performs a specific job in the cell? Choices: - mitochondria - nucleus - ribosome - organelle A:
(Answer)
organelle
Ques: Answer the following question given this paragraph: simple sugar that all living things use to store and transport energy. Q: What is the simple sugar that living things us to store energy? Choices: - nicotine - brown - chloride - glucose A:
Ans: glucose
(Q).
Answer the following question given this paragraph: Some bacteria are spread by vectors. A vector is an organism that spreads bacteria or other pathogens. Most vectors are animals, commonly insects. For example, deer ticks like the one in Figure below spread Lyme disease. Ticks carry Lyme disease bacteria from deer to people when they bite them. Q: What is an organism that spreads bacteria or other pathogens? Choices: - plane - section - arc - vector A:
(A).
vector
Ques:Answer the following question given this paragraph: Hydrogen bonds between water molecules explain some of water's properties. For example, hydrogen bonds explain why water molecules tend to stick together. Have you ever watched water drip from a leaky faucet or from a melting icicle? If you have, then you know that water always falls in drops rather than as separate molecules. The dew drops in Figure below are another example of water molecules sticking together. Q: What explains why water molecules tend to stick together? Choices: - helium bonds - covalent bonds - mineral bonds - hydrogen bonds A:

Ans:hydrogen bonds
Ques:Answer the following question given this paragraph: Visit this site (http://openstaxcollege. org/l/fermentation2) to see anaerobic cellular respiration in action. Other fermentation methods occur in bacteria. Many prokaryotes are facultatively anaerobic. This means that they can switch between aerobic respiration and fermentation, depending on the availability of oxygen. Certain prokaryotes, like Clostridia bacteria, are obligate anaerobes. Obligate anaerobes live and grow in the absence of molecular oxygen. Oxygen is a poison to these microorganisms and kills them upon exposure. It should be noted that all forms of fermentation, except lactic acid fermentation, produce gas. The production of particular types of gas is used as an indicator of the fermentation of specific carbohydrates, which plays a role in the laboratory identification of the bacteria. The various methods of fermentation are used by different organisms to ensure an adequate supply of NAD+ for the sixth step in glycolysis. Without these pathways, that step would not occur, and no ATP would be harvested from the breakdown of glucose. Q: Obligate anaerobes live and grow in the absence of what? Choices: - molecular carbon - molecular nitrogen - atomic oxygen - molecular oxygen A:

Ans:
molecular oxygen
