Explanation:
After repeated stimulation by antigen, B cells can make antibodies that bind their antigen with much higher affinity a process called affinity maturation. ... Thus, antigen stimulation greatly increases the antibody arsenal. Antibodies are proteins, and proteins are encoded by genes.
<h3>Each secondary spermatocyte completes the second meiotic division without the replication of DNA and produces 2 spermatids each containing 23 chromosomes. Spermatids undergo morphologic alteration (spermiogenesis) to become mature spermatozoa.</h3>

Answer:
Notice that many amino acids are represented in the table by more than one codon. For instance, there are six different ways to "write" leucine in the language of mRNA (see if you can find all six).An important point about the genetic code is that it's universal. That is, with minor exceptions, virtually all species (from bacteria to you!) use the genetic code shown above for protein synthesis.
Explanation:
Answer:
Barrier islands form in three ways. They can form from spits, from drowned dune ridges or from sand bars. Longshore drift is the movement of sand parallel to the shore caused by the angle of the waves breaking on the beach. When a storm such as a hurricane digs an inlet through the spit a barrier island is formed. Barrier islands are a specific type of island that lie parallel to the coastline of a larger mainland. They are separated from shore by a bay, lagoon or sound and because of where they are situated, they protect the coast from being directly impacted by storm waves or winds.
