Answer: The main reason why only 2 molecules of NADH is formed during glycolysis when it appears that as many as a dozen could be formed is because during glycolysis,most of the free energy that are available from the oxidation of glucose remains in one of the products of glycolysis known as pyruvate which acts like glucose but doesn't undergo metabolism.
Glycolysis is the splitting of sugar molecules into useable/ manageable forms,it can also be seen as the aerobic catabolism of sugar inorder to produce energy in the form of ATP,NADH and PYRUVATE.The following are the products of glycolysis; pyruvate,2 molecules of ATP and 2molecules of NADH.
Pyruvate are used in aerobic respiration or anaerobic respiration if oxygen is not available.

Answer:
A. Variably expressive and incompletely penetrant
Explanation:
Incompletely penetrant is a genetic term which means the genetic trait is visible in a fraction of people.
Variable expressivity is the range of signs and symptoms developed in different people with the same genetic condition.
Only some of the members who have inherited the mutant allele have a second toe longer than the big toe signifies variably expressive trait while the extent of webbing varying signifies incomplete penetrant.
Benthic sessile animals usually utilize external fertilization. They are marine animals and water helps in the mobility of male sperms towards the egg. The process through which eggs and sperms are released into the water is known as spawning. Some marine plants like algae also use external fertilization for reproduction.
