Answer:
Option D
Explanation:
In 1972, the fluid mosaic model was proposed by S. J. Singer and G. L. Nicolson to describe the structure of the plasma membrane found I living cells. The model describes the plasma membrane to possess components including phospholipid, proteins and cholesterol.
The phospholipid is arranged in two layers comprising of glycerol, two fatty acids and a phosphate group. The fatty acids which forms the tail are hydrophobic (water-fearing) while the phosphate group is water-loving (hydrophobic) giving the plasma membrane an AMPHIPATHIC nature. The other component as proposed by the model are membrane proteins and cholesterol, all responsible for the fluidity of the membrane.
Explanation:
Evolution is a slow natural process occurring in living organisms which explains the formation of the diversity of organisms on Earth. In simple terms, evolution explains how life survived on Earth after the origin of life but it cannot explain the origin of life. However, modern evolutionary biologists are now trying to decode the origin of life through evolutionary evidence and support that earlier form of life originated in the large oceans around 3.5 billion years ago. These organisms are simple living unicellular organisms which later evolved into the eukaryotic organisms.
Buildup of organisms means that the species number is pretty high.
Gradual change means that it was a slow, calm time to make the change.
I hope this helps!!
Answer:
<h3>A) Enzymes are highly specific protein catalysts</h3>
Explanation:
- Enzymes are highly specific protein catalysts i.e. it react with only that substrate for which it has been made.
- Enzymes have an active site by which it binds to substrate at that specific site.
- Enzymes lowers the activation energy required for completion of a chemical reaction. As a result rate of the reaction increases.
- Enzymes never participate in a chemical reaction rather they are obtained back in its original form on the completion of the reaction.
