The answer is; A & C
The lagging strand is replicated in fragments called Okazaki fragments, each initiated by a primer. The fragments are later joined into one strand by DNA ligase. Replication occurs by adding nucleotides to the 3’ end of a preceding nucleotide. Because the lagging strand is antiparallel to the leading strand, the replication of the lagging strand is in the opposite direction as the replication fork direction. This is why the lagging strand is replicated in fragments because replication is being carried out by a single DNA polymerase (moving in the direction of the replication fork) per replication fork.
Prostaglandin is released in response to to a bee sting or pollen.
<h3>What is an allergic response?</h3>
An allergic response is a series of reactions induced by the immune system of the body due to the presence of a foreign substance known as an allergen.
A bee sting or pollen can be recognized as allergen and results in the release of prostaglandins by mast cells.
In conclusion, prostaglandins are produced in response to allergens.

In cardiac muscle
a. an action potential spreads throughout the Z discs.
b. intercalated discs connect the muscle fibers together.
c. calcium enters the cell from storage chambers called intercalated discs.
d. potassium is released from the sarcoplasmic reticulum
Answer:
b. intercalated discs connect the muscle fibers together.
Explanation:
Intercalated discs are components of the muscles found in the heart(cardiac muscles).
Intercalated discs join the cardiomyoctes (muscle cells or fibers) together so that they can function as one and transmit signals amongst themselves during the contraction of the heart.
Intercalated discs are made of up desmosomes and gap junctions.
Intercalated discs are found on the lining of the sacromere and can only be seen by using a microscope to observe the longitudinal section of the heart tissue.
