Answer:
The amount of target DNA segments doubles with each cycle of PCR.
Explanation:
A polymerase chain reaction is an in vitro technique that is performed in the labs to replicate the DNA from a very small amount of DNA sample. The DNA sample is replicated or double in a very small amount of time that is the target sample doubles after each cycle.
The PCR technique is based on the DNA replication mechanism and thus employs the primer, A Taq DNA polymerase enzyme and the adequate amount of temperature.
Thus, the selected option is correct.
I’m pretty sure it’s skeletal muscle:) hope you have a nice day
Answer:
By increasing the enzyme concentration, the maximum reaction rate greatly increases. Conclusions: The rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction.
Answer:
The crab has just molted and the new exoskeleton has not yet hardened.
Explanation:
Crabs have an exoskeleton or shell which protects and supports them. From time to time crabs molt i.e. they discard the old exoskeleton and begin forming a new one. This process is a part of their normal growth. Soft-shell crabs had recently undergone molting and the new shell had just started to form. Hence, it has not hardened completely and is comparatively soft. Soft-shell crabs are in popular demand because it is easier to remove the soft shell and access the meat as compared to the normal crab.
Answer:
Circulation and Digestion
The muscular system and the circulatory system work with the small intestine. The muscular system helps the small intestine break down food. The circulatory system works with the small intestine and gets nutrients to the rest of the body.
