Answer:
Option-A
Explanation:
The nervous system which is activated during stress condition is known as the sympathetic nervous system.
The sympathetic system produces the response to fight or flight in the body. The body releases hormones during stress condition which are the epinephrine and the cortisol. Both the hormones are produced from the adrenal gland.
In the given question, since the person is in stressed condition but she is still fighting therefore the stress hormones are produced in large amount and the main hormones are the epinephrine and cortisol.
Thus, Option-A is correct.

Answer:
a. genetic recombination
Explanation:
During meiosis, homologous chromosomes synapse in the zygotene stage of prophase-I of meiosis-I. During pachytene of prophase-I, these paired homologous chromosomes exchange some genetic segment between their non-sister chromatids. This process of genetic recombination between the homologous chromosomes is called crossing over. Genetic recombination gives rise to recombinant chromatids. These recombinant chromatids carry some new allelic combinations which were otherwise not present in the parental chromatids.
