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.
It is negative selection <span />
The main things the WWF is doing with regard to circle hooks are supporting innovation and educating people.
Circle hooks help to reduce sea turtle deaths by up to 90%. The WWF has encouraged the elimination of tariffs on these hooks, and funds for further innovation for safer hooks. It has also led education initiatives to inform individuals, industries, and governments of the dangers of J-shaped hooks.
Answer:
A) rigor mortis
Explanation:
Rigor mortis is the condition of the partial contraction of muscles when the muscles cannot contract or stretch. It occurs after death as the ATP supply to muscle cells stops. The leaky cellular membranes results in leakage of calcium ions from the sarcoplasmic reticulum into the sarcoplasm. The presence of calcium in sarcoplasm triggers the binding of myosin heads to actin. The myosin heads remain attached to actin and muscles are prevented to be relaxed.
Answer:
1. Gel electrophoresis
2. Suspect 2
3. The suspect's DNA matches with the DNA found at the crime scene.
4. The size of the "bands," and thus their relative resistance to movement in the agarose gel, causes them to spread out on the fingerprint.
