The correct answer is they filter urea from blood and produce urine.  
<span>
Nitrogenous wastes tend to form toxic ammonia which needs to be removed. Terrestrial animals must detoxify ammonia by converting it into a relatively nontoxic molecule-urea (it occurs in the urea cycle). The urea cycle mainly occurs in the liver and the produced urea is then released into the blood. It travels to the kidneys where is filtrated and excreted in urine.</span>

A total of _____ amino acids compose the majority of protein in living things and nine are _____ to human
Evgen [1.6K]

A total of <u>20</u> amino acids compose the majority of protein in living things and nine are <u>essential</u> to human.

  • All living organisms, from bacteria to people, depend on amino acids for survival.
  • The same 20 types of amino acids are present in all living things.
  • Only 21 amino acids are required by the human body to create all the proteins required for growth and function.
  • Your body can create thousands of different types of proteins with only the same 21 amino acids because they can be ordered in a wide variety of ways.
  • The body is unable to produce essential amino acids. They must therefore originate from food.
  • Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.

TRUE/FALSE
kotykmax [81]

Answer:

False

Explanation:

A double-helical DNA molecule consists of two DNA strands. A DNA strand has free 5' phosphate at one end and a free hydroxyl group (OH) at its 3' end. A DNA double helix is said to be antiparallel since each end of the double helix has an exposed 5' phosphate on one strand and a free 3' hydroxyl group (OH) on the other. This means that the two DNA strands run in opposite directions. A phosphate group is always esterified to the 5' carbon of the pentose sugar; never at its 3' end.
