Q: What do we call the most widely accepted cosmological explanation of how the universe formed? Read this paragraph and choose the correct option from the provided answers: There is a great deal of evidence that the Universe started with a big bang. The Big Bang theory is the most widely accepted cosmological explanation of how the Universe formed. Think about the expanding Universe, then reverse it. If we start at the present and go back into the past, the Universe gets smaller. What is the end result of a contracting Universe? A point. Choices: - big crunch theory - singularity theory - big light theory - big bang theory A:
big bang theory

Q: What type of eggs do fully terrestrial vertebrates carry? Read this paragraph and choose the correct option from the provided answers: The amniotic egg is an important adaptation in fully terrestrial vertebrates. It first evolved in reptiles. The shells of reptile eggs are either hard or leathery. Choices: - epithelial - amphibious - aqueous - amniotic A:
(Answer)
amniotic

Ques: Q: What includes all living things within all their environments, including everywhere life exists, from the upper atmosphere, to the top of the soil, to ocean bottoms? Read this paragraph and choose the correct option from the provided answers: The biosphere includes all living things within all of their environments. It includes every part of the environment where life exists, from the upper reaches of the atmosphere to the top few meters of soil, to the bottoms of the oceans. An ecosystem is made up of the relationships among smaller groups of organisms with each other, and with their environment. Scientists often speak of the interrelatedness of living things, because, according to evolutionary theory, organisms adapt to their environment, and they must also adapt to other organisms in that environment. Choices: - biome - community - habitat - biosphere A:
Ans: biosphere

Q: What is the term for a scalar measure of how quickly an object is moving along this line? Read this paragraph and choose the correct option from the provided answers: One dimensional motion describes objects moving in straight lines. Speed is a scalar measure of how quickly an object is moving along this line. Velocity is speed with a direction, making it a vector. If an object's velocity changes with time, the object is said to be accelerating. When restricted to one dimension, there are only two possible directions for the velocity and acceleration vectors to point in. As we'll see in the next chapters, understanding an object's acceleration is the key to understanding its motion. Choices: - velocity - motion - force - speed A:
(A).
speed

Ques:Q: What type of air may get stuck on the windward side of a mountain range? Read this paragraph and choose the correct option from the provided answers: Maritime air may become stuck on the windward side of a mountain range. For this reason it is unable to bring cooler air farther inland. Choices: - brisk air - live air - steady air - maritime air A:

Ans:maritime air

Question: Q: What devices do astronomers use to see objects at wavelengths all across the electromagnetic spectrum? Read this paragraph and choose the correct option from the provided answers: Many extremely interesting objects can't be seen with the unaided eye. Astronomers use telescopes to see objects at wavelengths all across the electromagnetic spectrum. Some very hot stars emit light primarily at ultraviolet wavelengths. There are extremely hot objects that emit X-rays and even gamma rays. Some very cool stars shine mostly in the infrared light wavelengths. Radio waves come from the faintest, most distant objects. Choices: - microscopes - spectrographs - levels - telescopes A:
Answer:
telescopes
