Please help me out by answering all the questions!!
Markita is sitting in the first row of a baseball game, when a foul ball comes streaking at her head. She barely has time to move out of the way, and narrowly avoids getting hit. Which part of her nervous system will go into overdrive and mobilize her energy resources in the face of this near disaster?
the sympathetic nervous system
the rostral nervous system
the caudal nervous system
the parasympathetic nervous system
The genome is the complete
collection of sexual characteristics regulated by the X and Y chromosomes.
range of traits that contribute to reproductive success.
genetic profile common to members of a species.
set of interactions between genes and environment.
The Central Nervous System is:
all portions of the nervous system that are not encased in bone
made up of the brain and spinal chord
the portion of the nervous system that controls the beating of the heart and other “central” organs
covered in a myelin sheath
Which comparison best explains the difference between the sympathetic and parasympathetic nervous systems?
The sympathetic nervous system is like a car’s gas pedal, while the parasympathetic nervous system is like a car’s brake pedal.
The sympathetic nervous system is like a lawn mower, while the parasympathetic nervous system is like the lawn.
The sympathetic nervous system is like a vacuum cleaner, while the parasympathetic nervous system is like the bag in a vacuum cleaner.
The sympathetic nervous system is like a airplane, while the parasympathetic nervous system is like a boat.

Wendy’s mother has blue eyes and her father has brown eyes. The allele for brown eye color is dominant (B) to the allele for blue eye color (b), but Wendy has blue eyes. Therefore, Wendy’s ________ must be ________ and her father’s must be Bb.
- the sympathetic nervous system( it helps in the fight and flight response, hence the correct option)
- the rostral nervous system (helps in flexing and standing , functions relating to the nose facing or front part)
- the caudal nervous system (helps in flexing and standing , functions
relating to the tail facing or back part)
- the parasympathetic nervous system ( functions of the unconscious like
sexual arousal, salivation,etc.)
