Ques: Q: The resultant solution will contain the same amount of solute but a greater amount of what? Read this paragraph and choose the correct option from the provided answers: Many chemicals that we use on a daily basis are transported in a concentrated form but used in a more diluted form. For example, concentrated cleaners are often diluted before they are used. To perform a dilution , pure solvent is added to a concentrated solution in order to make a less concentrated (more dilute) solution. The resultant solution will contain the same amount of solute but a greater amount of solvent. It will therefore have a lower concentration than the original solution. When performing a simple dilution, the concentration and volume of the initial solution are related to the new concentration and volume as follows:. Choices: - calcium - liquid - pigment - solvent A:
Ans: solvent

Ques: Q: What is the term for genes that control the expression of other genes within specific regions of cells in the developing organism? Read this paragraph and choose the correct option from the provided answers: Gap genes control the expression of other genes within specific regions of cells in the developing organism. This allows specific genes to be expressed in certain cells at the appropriate stage of development. Choices: - expression genes - age genes - data genes - gap genes A:
Ans: gap genes

Ques: Q: What happens to volume as the temperature increases? Read this paragraph and choose the correct option from the provided answers: The volume increases as the temperature increases. The result has three significant figures. Choices: - volume fluctuates - volume decreases - volume is unchanged - volume increases A:
Ans: volume increases

Ques: Q: What type of switch automatically opens a circuit if too much current flows through it? Read this paragraph and choose the correct option from the provided answers: A circuit breaker is a switch that automatically opens a circuit if too much current flows through it. This could happen if too many electric devices are plugged into the circuit or if there is an electric short. Once the problem is resolved, the circuit breaker can be switched back on to close the circuit. Circuit breakers are generally found in a breaker box that controls all the circuits in a building. Choices: - toggle switch - regulator switch - kill switch - circuit breaker A:
Ans:
circuit breaker
