The correct option is A.
Sensory receptors are structures which react to physical stimuli in the environment whether the stimuli is external or internal. The sensory nerves receive the information and conduct a process of generating nerve impulses which is transmitted to the brain for interpretation and perception.
Because the world is constantly evolving and changing, so nature has to keep up with that constant change with natural selection.

The organelle responsible in increasing quantities in the
liver cells of an individual who have abused other drugs or even alcohol in a
regular basis is the mitochondria. It is because if a person has abused alcohol
or drugs, the liver cell of the individual will likely have an increase
quantities of mitochondria.
Answer:
1
Explanation:
According to the information in this question, a gene coding for flower color in a plant is involved. The allele for red color (R) is incompletely dominant over the allele for white color (r) to form an intermediate phenotype/color i.e. Pink that is heterozygous (Rr) for the gene.
If two pink plants are crossed i.e. Rr × Rr, each parent will produce R and r gametes. Using these gametes in a punnet square (see attached image), the following offsprings will result: RR, Rr, Rr, and rr.
Out of these four offsprings;
1 RR is red : 2 Rr is pink: 1 rr is white
Hence, If four plants are produced from this cross, according to this question, the expected number of white-flowered plants will be 1 out of 4.
