Answer the following question given this paragraph: Most substances have three distinct phases: gas, liquid, and solid. Phase changes among the various phases of matter depend on temperature and pressure. The existence of the three phases with respect to pressure and temperature can be described in a phase diagram. Two phases coexist (i. , they are in thermal equilibrium) at a set of pressures and temperatures. These are described as a line on a phase diagram. The three phases coexist at a single pressure and temperature. This is known as the triple point and is described by a single point on a phase diagram. A gas at a temperature below its boiling point is called a vapor. Vapor pressure is the pressure at which a gas coexists with its solid or liquid phase. Partial pressure is the pressure a gas would create if it existed alone. Dalton's law states that the total pressure is the sum of the partial pressures of all of the gases present. Q: Temperature and pressure affect changes in phases or states of what? Choices: - homeostasis - decay - energy - matter A:
matter

Answer the following question given this paragraph: One idea is that evolution happens. Evolution is a change in the inherited traits of organisms over time. Living things have changed as descendants diverged from common ancestors in the past. Q: What is defined as a change in the inherited traits of organisms over time? Choices: - variation - divergence - generation - evolution A:
(Answer)
evolution
Ques: Answer the following question given this paragraph: Meiosis is the type of cell division that produces gametes. Q: What is the type of cell division that produces gametes? Choices: - electrolysis - mitosis - budding - meiosis A:
Ans: meiosis

Answer the following question given this paragraph: 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. Q: What devices do astronomers use to see objects at wavelengths all across the electromagnetic spectrum? Choices: - microscopes - spectrographs - levels - telescopes A:
(A).
telescopes
Ques:Answer the following question given this paragraph: The deep-water zone is dark so there is no photosynthesis. Most deep-water organisms are scavengers. They feed on dead organisms that fall to the bottom of the lake. Crabs and catfish are two of these types of organisms. Fungi and bacteria are decomposers that live in the deep zone. Q: Why does photosynthesis not occur in the deep-water zone? Choices: - it is cold - it is pressurized - it is stagnant - it is dark A:

Ans:it is dark
Question: Answer the following question given this paragraph: Humans could not live on Earth if it were not for protists. Why? Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. All protists make up a huge part of the food chain. Q: What produces almost one-half of the earth's oxygen through photosynthesis? Choices: - prokaryotes - algae - arthropods - protists A:
Answer:
protists
