Answer:
Fossils are the some traces or portions of the animals or plants, buried and preserved from past in rocks, sediments or ice.
Explanation:
Correct match is as follows-
- Mold and cast fossils- An organism is buried in sediment after it dies.The hard part of organism leave behind a empty space imprinted in the rock. Later sediments and minerals fill the space and harden to make the original copy of the organisms.
- Carbon film fossils- An organism buried in sediments gets squeezed and heated inside the earth , leaving behind a thin carbon outline of the organism on a rock.
- Amber fossil- An organism covered in tree resin or tree sap , which then hardens with the body of the organisms preserved inside.
- Ice fossil- An organism dies in a cold place on earth , its body becomes frozen and covered in layers of ice . The hard and soft part of the body may be preserved.
Elector would be that a laser converts electrical energy
Hexanoyl Chloride on treatment with excess
Ethyl Magnesium Bromide yields
tertiary Alcohol. In this reaction Hexanoyl chloride is first converted into
intermediate ketone (Octane-3-one), secondly the ketone formed is further reduced to <em>
tert.</em>
Alcohol (3-Ethyloctan-3-ol), The reaction along with mechanism is shown below,
Volume can be measures in liters
energy is transferred through vibrations of electric and magnetic fields
