B, both chemical and biological factors are involved
Answer:
Central Nervous System
Spinal Cord
Peripheral Nervous System
Explanation:
The Nervous System has two MAIN parts. The Central Nervous System is made up of the brain and spinal cord.
The Peripheral Nervous System is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
Hopefully, this answers's your question.

The factors that determines the rate of diffusion in the biological system include: temperature, size of the particles, diffusion distance and concentration gradients. Of all these factors, the most important one is the TEMPERATURE.
The relationship between temperature and the rate of diffusion is a direct one, that is, the higher the temperature the higher the rate of diffusion and vice versa. At high temperature the molecules in the particles move faster because they have higher amount of energy.
two steps of expression of a gene in their correct chronological order are Transcription then translation.(option a)
The process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce protein or non-coding RNA end products and ultimately affect a phenotype as the final effect is known as gene expression.
It comprises two significant stages: translation and transcription, Gene expression is made up of transcription and translation working together to form a polypeptide.
- The production of RNA from DNA is known as transcription. The enzyme RNA polymerase acts as the catalytic agent.
- The process by which a messenger RNA's genetic code is decoded to produce a particular polypeptide chain is known as translation. A particular amino acid is specified in each genetic code.
