Ques: Q: What are major temperature zones primarily based on? Read this paragraph and choose the correct option from the provided answers: Temperature falls from the equator to the poles. Therefore, major temperature zones are based on latitude . They include tropical, temperate, and arctic zones (see Figure below ). However, other factors besides latitude may also influence temperature. For example, land near the ocean may have cooler summers and warmer winters than land farther inland. This is because water gains and loses heat more slowly than does land, and the water temperature influences the temperature on the coast. Temperature also falls from lower to higher altitudes. That's why tropical zone mountain tops may be capped with snow. Choices: - altitude - longitude - gps - latitute A:
Ans: latitute

Ques: Q: What 2 things keep polar bears warm in their arctic ecosystem? Read this paragraph and choose the correct option from the provided answers: Thick fur and a layer of blubber keep polar bears warm in their Arctic ecosystem. Why do you think their fur is white? Why might it be an adaptation in an Arctic biome?. Choices: - hibernation, thick fur - colourful fur , blubber - camouflage, blubber - thick fur, blubber A:
Ans: thick fur, blubber

Ques: Q: Getting the same result when an experiment is repeated is called what? Read this paragraph and choose the correct option from the provided answers: Scientists also have to "check their work. " The results of an investigation are not likely to be well accepted unless the investigation is repeatedusually many timesand the same result is always obtained. Getting the same result when an experiment is repeated is called replication . If research results can be replicated, it means they are more likely to be correct. Repeated replication of investigations may turn a hypothesis into a theory. On the other hand, if results cannot be replicated they are likely to be incorrect. Choices: - mutation - initiation - repetition - replication A:
Ans: replication

Ques: Q: Mutations which benefit the organism in which they occur are known as? Read this paragraph and choose the correct option from the provided answers: Some mutations have a positive effect on the organism in which they occur. They are called beneficial mutations . They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time. There are several well-known examples of beneficial mutations. Here are just two:. Choices: - extraordinary mutations - helpful mutations - healthy mutations - beneficial mutations A:
Ans:
beneficial mutations
