Why do scientists study fossils?

Biology
1 answer:
Tasya [4]3 years ago
6 0
Hi,

By studying fossils, scientists can learn how life has changed over time, how earth's surface has changed and what past environments were like. Fossils form when living things die and are buried by sediment; they are usually found in Sedimentary rock. Only the hard parts of organisms generally leave fossils because the soft parts generally decay too quickly to fossilize. In case you didn't know, there are two types of fossils; rock fossils and preserved fossils.

Option c) is the correct option above.

<span>c) Fossils give information about the time period in which organisms lived in the past.

Which statement describes the reaction for cellular respiration?
mixer [17]

The equation is glucose + oxygen carbon dioxide + water and energy is produced in the form of ATP.

Explanation:

Cellular respiration is a metabolic process in which glucose combines with oxygen to produce carbon dioxide and water with energy stored as ATP.

    Glucose + Oxygen gas → Carbon dioxide + Water + energy in ATP

ATP is Adenosine TriPhosphate.

In the body, during cellular respiration, oxygen gas is inhaled and carried to sites in the body where food in form of glucose obtained from plant is broken down.

When food is broken down aerobically i.e in the presence of oxygen gas, carbon dioxide and water is produced and energy is stored in form of ATP.

The diagram below shows the chemical structure of a type of lipid molecule called a phospholipid.
SVEN [57.7K]

Answer No 1:

Phospholipids are made up of phosphorus head and two fatty acid molecules.  These phosphorus head and fatty acid tail is joined together by glycerol. Fatty acid molecules are made up of Carbon, hydrogen and oxyge. Hence,carbon and hydrogen can be said as two other elements present in phospholipids.

Answer No 2:

The building blocks of lipids are glycerol and fatty acids.

Lipids can be described as vital organic molecules which are not soluble in water. They are made up of chains of carbon, hydrogen and oxygen. Someof the examples of lipids are fats and oils. Lipids are the main molecules present in an organisms cell membrane and hence have huge biological importance.

Answer No 3:

Lipids are biologically important molecules as they play very vital roles in the functioning of an organisms body. Two of the functions of lipids are:

  • Lipids and phosphorus molecules combine to form phospholipids. The phospholipids are the main molecules out of which the cell membrane is made. Hence, lipids play an essential role in providing the cell membrane its structure.
  • Lipids store energy and provide insulation to the body of an organism.
