Answer:
Option A
Explanation:
Xeroderma pigmentosum arises as a result of the cell being unable to correct lesions induced by UV. This can be as a result of mutations in the enzymes which include XP A-E needed for correction of the lesions. Failure to correct these lesions leads to their accumulation and then damage to the cell.
Answer: The correct is- B) Sucrose.
Carboydrate is one of the four major biomolecules that is composed of carbon, hydrogen, and oxygen atoms. The ratio of hydrogen and oxygen atom is 2:1. Simple carbohydrate is also called sugar.
Sucrose is a disaccharide ( made up of two simple sugar units) as it is made up of glucose and fructose.
Therefore, sucrose is a carbohydrate molecule.
Organic would be living material, so no....
Pathogens would be bacteria and fungi, so no...
thermal would be heat, so no...
must be macroscopic
This is called camouflage
.
Camouflage is a type of deceptive coloration that can that help an organism blend in or hide in its surroundings. Camouflage can be colors or patterns or the combination of both. Organisms are not easy to find when they are camouflaged. Examples include big cats such as leopards, jaguars and cheetahs that have spots which help them blend into their environment. Also, the red squirrel has reddish-brown fur on top of it which makes it harder for predators to see the squirrel when it is on the ground.
The right answer is D). Water
Proteins are amino acids that contain carbon atoms.
Carbohydrates contain carbon atoms, hence the suffix "carbo".
Lipids are rich in carbon atoms.
Water is an important biological constituent, and liquid water is essential for all known living organisms. Given its vital nature, its importance in the economy and its unequal distribution on Earth, water is a natural resource whose management is subject to strong geopolitical issues.
