Which of the following is a pseudo-ruminant?
cow
pig
crow
horse

The horse is a pseudo-ruminant.

Explanation:

Pseudo ruminants (for example, horses and rabbits), have a stomach similar to that of other animals that have a simple stomach. However, they have an extensive area called cecum that gives them an intermediate characteristic between ruminants and non-ruminants.

Horses are pseudo ruminants, so they only have one cavity in their stomach, unlike cows or sheep that have four cavities. They can digest the cellulose of the herb because they have a very developed blind, through which food passes before reaching the large intestine.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

sorry, but you do not have posted the diagram.
