Answer:
B. Water and ATP
Explanation:
NADH is produced during glycolysis and Krebs cycle. While CO2 is also produced during Krebs cycle. Pyruvate is produced during Glycolysis. ETC produces ATP and H2O.
The statement that provides evidence of the common ancestry of all life is near universality of the genetic code (option A).
<h3>What is the genetic code?</h3>
Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.
The genetic code has the following characteristics:
- The genetic code is universal i.e all known living organisms use the same genetic code.
- The genetic code is unambiguous i.e. each codon codes for just one amino acid (or start or stop)
- The genetic code is redundant i.e. most amino acids are encoded by more than one codon.
Therefore, the statement that provides evidence of the common ancestry of all life is near universality of the genetic code.

Answer:
A. both parents had to give a recessive trait to their offspring
Explanation:
Both parents need to give a recessive trait because if there's any dominant ones, it'll overpower the recessive ones
This statement is true. Only active transport can move molecules up a concentration gradient using energy. Passive transport on the other hand, uses no energy and occurs naturally. Therefore molecules can only move a concentration gradient.
Formation of island chains occurs when convergent boundaries interact and is denoted as option A.
<h3>What is Convergent boundary?</h3>
This refers to an area where two or more lithospheric plates collide in the earth.
When the y interact, island chains are formed which consists of sea with sparse islands around the area.
