At a glance this one's confusing, I agree.
Genetic engineering has made it easier for forensic scientists to differentiate human DNA beyond simple blood sampling. This inevitable led to release of innocent accused prisoners.
This reaction occurs in the thylakoids of the chloroplast
The overproduction of offspring leads to competition in which only the better adapted organisms survive and reproduce.
Answer:
adaptation-the inherited characteristic that increases an organism's chance of survival and to reproduce.
fitness -the ability of an organism to survive and reproduce in its environment
Answer: muscle contraction of sustained force resulting from repeated action potentials. (Option A)
Explanation: Tetanus is also called physiologic tetanus. Tetanus refers to the contraction of the muscle, which is established when the motor nerve that supply nerves to a skeletal muscle produces action potentials at a very high degree.
However, tetanic contraction is usually a normal process (such as when carrying a heavy box). Also, muscles can be shorten, lengthen or remain constant length during tetanic contractions.
