Air pressure is the amount of pressure exerted by the air in a particular air mass. Humidity is a measure of the water content of the air mass. Clouds are tiny drops of water or ice that form in the atmosphere. Wind is a process of movement of air that occurs due to the uneven heating of the Earth's surface.
Answer:
The correct statements are that the first calorimeter is reliable but not valid, and the second calorimeter is valid and reliable.
Explanation:
The first calorimeter is reliable as the reading demonstrated by it is similar when each time the experiment is performed, however, the result attained is not correct, though it is reliable. On the other hand, the second calorimeter is both reliable and valid, as it is demonstrating the accurate results from time to time. This is valid as it is providing a similar result as that of the original readings.
Answer:
Evidence for evolution comes from many different areas of biology:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
Answer:
Saturated fatty acids don't have double bond between two carbon atoms, while in unsaturated fatty acids have atleast one double bond between two carbon atoms.
I've a trick for you to remember this
Saturated → Single Bond (you can remember by The first later of both word i.e., "S")
Unsaturated → Double Bond
