The stimuli alter the activity of excitable sensory cells via Transduction.
Transduction is the method by which a virus transmit genetic material from one bacterium to another.
<h3>What is Transduction?</h3>
Transduction is defined as the genetic transfer from a donor cell to another recipient by a bacteriophage. The transduction consists of two stages:
-The formation of the transducer phage particle, the genetic material is introduced inside the capsid of a phage.

Gametes are produced in meiosis, they are a sperm or egg that is fused together with another gamete to make a zygote.
Crossing over is important because it creates genetic variability.
<h3>What is crossing over?</h3>
It is the exchange of chromosomal segments between non-homologous chromosomes in a tetrad.
Since chromosomal segments contain genes at different loci, the exchange will increase the genetic variability of the new chromosomes.
Thus, the daughter cells carrying the recombined chromosomes will be genetically variable from not just the parent cell, but fellow daughter cells.

Natural gas: Through hydraulic fracturing
Answer:
C
Explanation:
The meninges are the membranous tissues that cover the spinal cord and the brain, providing support and protection to these organs. They are of three layers.
A) The Dura mater
B) The arachnoid mater
C) The pia mater
The Dura is the outermost meningeal layer and lies directly under the vertebral column bones and skull. The subdural space is the space between the Dura mater and the Arachnoid mater.
The Arachnoid mater lies in the middle of the Dura and Pia mater. Under the Arachnoid layer is the subarachnoid space which contains the cerebrospinal fluid. The cerebrospinal fluid acts as a shock absorber and a cushion to the brain and spinal cord.
The Pia mater lies under the subarachnoid space and directly on the spinal cord and brain and is highly vascularised.
