It's basically when a person has one more chromosome than usual. You can find out whether someone has it at birth - but it's quite a visual disease sometimes but you SHOULD NOT diagnose it that way. When it comes to Down Syndrome you have a higher chance or hearing loss and heart defects. You'd need to take a genetic skin or blood test to find whether a person HAS Down Syndrome!
Good luck, rockstar! I hope you pass, and I definitely definitely definitely wish you the best! (:

Which of the following is a true statement?Anabolic pathways build molecules, require energy, and are endergonic.Anabolic pathwa
expeople1 [14]

Answer:

A: Anabolic pathways build molecules, require energy and are endergonic

Explanation:

Anabolism and catabolism are the two important process of metabolism - a process through which cells get energy to drive various processes within the body and get rid of toxic wastes.

Anabolic and catabolic reactions can be described as opposing sides of the same coin. While anabolism refers to the various reactions that build up molecules within the cell, catabolism has to do with the breakdown of big or complex molecules into smaller ones.

Both processes involves energy. Anabolic reactions require energy to drive the building up process and therefore referred to as endergonic reactions. On the other hand, catabolic reactions liberate energy during the breaking down of complex molecules and therefore referred to exergonic reactions.

A good example of anabolic reaction is photosynthesis which involves the building up of carbohydrate (glucose) using carbon-dioxide, water molecule and energy while a good example of catabolic reaction is respiration which involves the breakdown of carbohydrates into carbon-dioxide, water molecules and the release of energy.

Hence, the only correct option is A.
