A scientist examines unknown substance 1. It appears to be quite soft to the touch and when he tries to grind it up and place it in water, it does not dissolve. But he does find that it dissolves in hexane! He tries heating the substance and it pretty quickly melts around 180 degrees Celsius. He tries running an electric current through it and it did not conduct electricity at all. He tries to boil the liquid once he has melted it and he finds it boils quite quickly at a low boiling point. What kind of substance is it?

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.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

i have no clue hope you find the answer
