Ibeen having a problem with this question can you ? ?

(D) Water is denser than oil but less than syrup.

Explanation:

Given:

A picture of a jar containing three liquids.

The position of the syrup is at the bottom of the jar. The position of water is in middle and the oil is at the top.

We know that, the oil is the lightest in density when compared to syrup and water. So, it is at the top.

Now, since water is in the middle of the two, it means that density of water is greater than that of oil but less dense than that of syrup.

So, the density of the syrup is the greatest. Hence, it sits at the bottom.

Therefore, the best explanation is that water being less dense than syrup but more dense than oil, will be in the middle of two.

This explains the position of all the three liquids. Water is in the middle, oil at top and syrup at bottom.

So, the last option is correct.

carbon is found in all living things. carbon atoms move constantly through

living organisms, the oceans, the atmosphere, and the earth’s crust in what is

known as the carbon cycle. the directions taken by carbon atoms through this

cycle are very complicated and can take millions of years to make a full circle.

all animals, from humans to the dinosaurs are part of the carbon cycle. when

animals eat food, they get carbon in the form of carbohydrates and proteins.

in animals, oxygen combines with food in the cells to produce energy for daily

activity and then gives off carbon. the carbon combines with oxygen to form

carbon dioxide (co2) and is released back into the atmosphere as a waste

product when animals breathe and exhale.

from 145-65 million years ago, earth was much

hotter than today and covered with dense,

tropical swamp forests. the trees and other

plants were immense and

provided an endless supply of

food for the giant animals that

roamed the land. somewhere in

the air above one of these

forests, a lone carbon atom has joined

up with two oxygen atoms to form a molecule of co2.

the co2 molecule was sucked into the tiny holes (stomata) on the leaf of a

fern plant and joined with sunlight, chlorophyll and water to make food and

energy in the plant’s cells through photosynthesis. the oxygen (o2) from the

co2 molecule was sent back into the atmosphere; the carbon atom (c) was

detached and used to make a molecule of sugar.

if that carbon atom had been eaten instead, a totally

different situation would have developed. let’s say

that a giant plant-eating dinosaur (herbivore) ate the

fern for breakfast, and swallowed the carbon in the

fern in the form of carbohydrates and proteins. in

the process of respiration, oxygen combined with

the carbohydrates and proteins in the dinosaur’s cells

to provide energy for its daily activity.
