Ques: Answer the following question given this paragraph: In biology, energy is required for ecosystems to survive, as all living organisms need energy. Within an organism, energy is needed for growth and development of a biological cell or an organelle within that cell. Energy is also needed for all biochemical reactions within that cell. Therefore, energy is stored within cells in the chemical bonds of substances such as carbohydrates (including sugars), lipids, and proteins. This energy is released during aerobic respiration. Q: In biology, what is required for ecosystems to survive? Choices: - helium - space - minerals - energy A:
Ans: energy
(Q).
Answer the following question given this paragraph: The area of a surface is how much space it covers. It's easy to calculate the area of a surface if it has a regular shape, such as the blue rectangle in the sketch below. You simply substitute measurements of the surface into the correct formula. To find the area of a rectangular surface, use this formula:. Q: How much space a surface covers is known as what? Choices: - Flatness - Lenght - Height - area A:
(A).
area
Ques:Answer the following question given this paragraph: The sample in an experiment or other investigation consists of the individuals or events that are studied. Typically, the sample is much smaller than all such individuals or events that exist in the world. Whether the results based on the sample are true in general cannot be known for certain. However, the larger the sample is, the more likely it is that the results are generally true. Similarly, the more times that an experiment is repeated and the same results obtained, the more likely the results are valid. This is why scientific experiments should always be repeated. Q: What part of an experiment or other investigation consists of the individuals or events that are studied? Choices: - hypothesis - experimental control - independent variable - sample A:

Ans:sample
Ques: Answer the following question given this paragraph: The electron cloud of a helium atom contains two electrons, which can normally be expected to be equally distributed spatially around the nucleus. However, at any given moment the electron distribution may be uneven, resulting in an instantaneous dipole. This weak and temporary dipole subsequently influences neighboring helium atoms through electrostatic attraction and repulsion. It induces a dipole on nearby helium atoms (see Figure below ). Q: A weak and temporary dipole that influences nearby atoms through electrostatic attraction and repulsion is known as what? Choices: - a fused dipole - an incomplete dipole - an debased dipole - an instantaneous dipole A:
Ans:
an instantaneous dipole
