Which statement is an accurate comparison of the properties of compounds in the properties of the elements that compounds contain? a. they represent opposite characteristics. b. they are always identical. c. they are similar. d. they are different.

the compounds are formed from different atoms of elements. The elements are the purest form of a matter. They are made up of single kind of atoms.

When elements combine they form compounds. The elements combined completely lose their identity and forms a compound with very different properties. They are chemically as well as physically different from the elements used.

Example: water is formed from hydrogen and oxygen. and the properties of water altogether different form properties of both the elements hydrogen and oxygen (which are gas at room temperature)

So answer is : different

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
