A startle reflex (a), digestion (c), breathing (d) and heart pumping (e) are responses of the ANS, while arm/leg movement (b) is a response of the SNS. They are major divisions of the PNS.
The peripheral nervous system (PNS) serves to connect the central nervous system to different organs, limbs, and skin.
The PNS can be divided into Somatic Nervous System (SNS) and Autonomic Nervous System (ANS).
The Somatic Nervous System is responsible for controlling the voluntary movements of the body.
The Somatic Nervous System is responsible for regulating the involuntary movements (reflexes) of the body.

Answer :
There are two types of cell division: mitosis and meiosis. Choose which one your reffering to.
Explanation : Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. It is the duplicating of cells.
The process of independent assortment allows a species to be diverse. This process basically means that during meiosis, genes separate from one another independently :) hope this made sense
Answer:
Correct
Explanation:
A mutation within the promoter sequences could lead to an alteration of its transcription basal level when:
The mutation is different enough to lower the transcription factors affinity to bind to this region.
Lowering the affinity of RNA polymerase, by reducing either the length or the sequence composition.
Answer:
C, D, A, B, E
Explanation:
The sudden decrease or increase in the potential of cell membrane is Action potential. The stimulus (local current) allows change in the membrane potential, thus allowing depolarization of the membrane. This initiates the opening of Voltage Gated Na+ channels. The sodium starts entering the cell that is influx of Na+ and thus AP generated in adjacent axon segment. The sodium channels inactivates by membrane repolarization and activated pottassium channels allows the efflux of pottassium ions. The inactivation of potassium channels occurs by hyperpolarization ( low membrane potential) brings the membrane to its resting state. Thus, the correct order is C, D, A, B, E.
