Ques: Q: What captures carbon dioxide as it is emitted by a power plant before it enters the atmosphere? Read this paragraph and choose the correct option from the provided answers: Carbon sequestration captures carbon dioxide as it is emitted by a power plant before it enters the atmosphere. The carbon dioxide is then stored in another form. Carbon is sequestered naturally by forests. Trees take in carbon dioxide for photosynthesis. Artificial methods of sequestering carbon underground are being researched. This is just one of the geoengineering methods that are being researched for reducing carbon dioxide. Choices: - chemical sequestration - oxide sequestration - nitrogen sequestration - carbon sequestration A:
Ans: carbon sequestration

Ques: Q: Because dizygotic twins develop from two eggs fertilized by two sperm, they are no more identical than siblings born at what? Read this paragraph and choose the correct option from the provided answers: birth of dizygotic (or fraternal) twins. Because dizygotic twins develop from two eggs fertilized by two sperm, they are no more identical than siblings born at different times. Much less commonly, a zygote can divide into two separate offspring during early development. This results in the birth of monozygotic (or identical) twins. Although the zygote can split as early as the two-cell stage, splitting occurs most commonly during the early blastocyst stage, with roughly 70100 cells present. These two scenarios are distinct from each other, in that the twin embryos that separated at the two-cell stage will have individual placentas, whereas twin embryos that form from separation at the blastocyst stage will share a placenta and a chorionic cavity. Choices: - other times of day - different places - other eras - different times A:
Ans: different times

Ques: Q: What does a thermometer measure? Read this paragraph and choose the correct option from the provided answers: Temperature is the quantity measured by a thermometer. Temperature is related to the average kinetic energy of atoms and molecules in a system. Absolute zero is the temperature at which there is no molecular motion. There are three main temperature scales: Celsius, Fahrenheit, and Kelvin. Temperatures on one scale can be converted to temperatures on another scale using the following equations:. Choices: - oxygen - precipitation - size - temperature A:
Ans: temperature

Ques: Q: Where do birds store and moisten food that is waiting to be digested? Read this paragraph and choose the correct option from the provided answers: Birds have a sac-like structure called a crop to store and moisten food that is waiting to be digested. They also have an organ called a gizzard that contains swallowed stones. The stones make up for the lack of teeth by grinding food, which can then be digested more quickly. Both structures make it easier for the digestive system to produce a steady supply of nutrients from food. Choices: - nest - tree - gullet - crop A:
Ans:
crop
