Cells in the human eye send nerve impulses to the brain that causes the pupil to constrict. This is an example of a reaction to the light stimuli. Thus, the correct option is B.
Pupils are the part of eye which respond to three distinct kinds of stimuli which include their constriction in response to brightness of light, this is called as the pupil light response, constrict in response to near fixation which is known as the pupil near response, and dilate in response to increases in the arousal and mental efforts, either these are triggered by an external stimulus or occur spontaneously.
Light is the stimulus and the impulses in response to this reach the brain through the optic nerve and the response due to this is conveyed to the pupillary musculature through autonomic nerves which supply the eye.
Therefore, the correct option is B.

Answer: The balanced chemical equation for photosynthesis is 6CO2 + 6H2O + sunlight --> C6H12O6 + 6O2.
The balanced chemical equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2+ 6H2O + Energy.
Explanation: Photosynthesis and cellular respiration are two opposite reactions. In photosynthesis, plants use carbon dioxide, water and sunlight to produce glucose and oxygen while in cellular respiration, both plants and animals breakdown glucose in the presence of oxygen to produce carbon dioxide and water with the release of energy.
Photosynthesis occurs only in plants and some photosynthetic bacteria while cellular respiration occurs in both plants and animals. The energy released from the breakdown of glucose in cellular respiration is used to drive other cellular processes.
Each of the two processes depends on the other for the supply of its reactants. Photosynthesis depends on cellular respiration for the supply of carbon dioxide and water while cellular respiration depends on photosynthesis for the supply of glucose and oxygen.
The balanced chemical equation for photosynthesis is 6CO2 + 6H2O -> C6H12O6 + 6O2. The balanced chemical equation for cellular respiration is C6H12O6 + 6O2 -> 6CO2 + 6H2O. These equations represent the conversions that occur in photosynthesis and cellular respiration.
The balanced chemical equation for photosynthesis is. The equations represent the conversion of carbon dioxide and water to glucose and oxygen in photosynthesis, and the reverse conversion of glucose and oxygen to carbon dioxide and water in cellular respiration.
6CO2 + 6H2O → C6H12O6 + 6O2
The balanced chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O
The equations represent the conversion of carbon dioxide and water to glucose and oxygen in photosynthesis, and the reverse conversion of glucose and oxygen to carbon dioxide and water in cellular respiration.

Answer: Dominant: red, recessive: white.
Explanation:
Alleles are different forms or versions of a gene, and they can be described as either dominant or recessive.
Dominant traits are those that are seen in a heterozygous genotype. It means the organisms has two different alleles for a gene, one is dominant while the other one is recessive. A dominant allle dominates over the recessive alleles and it masks the effects of this recessive allele. This means, the offspring only needs to inherit one dominant allele to have a dominant trait.
In the example, a red-flowered plant is crossed with a white-flowered plant. And all plants on the next generation are red. If each plant from this offspring inherites one allele of each parent, they have one red allele and one white allele. Since they are all red, we can say red color is dominant and white color is recessive. Because red allele has a dominant phenotype.
