Answer:
The process in which glucose react with oxygen to provide energy and carbon dioxide and water is called <em><u>Cellular</u></em><em><u> </u></em><em><u>respiration</u></em><em><u> </u></em><em><u>.</u></em>
<h2>
<em><u>MORE</u></em><em><u> </u></em><em><u>TO</u></em><em><u> </u></em><em><u>KNOW</u></em><em><u> </u></em></h2>
- Glucose break down into 3 carbon molecule pyruvate .
- The energy produced is used to synthesis ATP which is a power house of cell.
- Cellular takes place in Mitochondria . It is an organelle in cell
- ATP is adenosine triphosphate
- ATP is utilised in maintained function of cell, synthesise protein and other works
<span>In
the process of polymerization, a chain of similar smaller molecules
called monomer join together to create very large molecules called
polymer. Through this chemical reaction, water is created as a
by-product. In contrast to hydrolysis or breaking down of polymers, a
water molecule is used to break the covalent bond that hold the
components of a polymer.</span>
Fossils can give information about past environmental conditions by showing the type of animal they belonged to. If a scientist found a whale fossil in a desert, he/she could assume that the desert was once an ocean as whales only live in oceans. If someone found a fossil of a lizard that inhabited trees, in the middle of the ocean, then he/she could assume that the ocean didn't exist at one point and instead, there might have been a forest in it's place.
Hope this helps!
