Answer:
Somatic
Explanation:
The somatic sensory system consist of sensory neurons and the neural pathways that produce response to the changes inside or at the surface of the body. The axons of sensory neurons connects and provide response to receptor cells.
The sensory neuron that generate response to a particular stimuli is named with the kind of stimuli, for example - heat stimulus activates the thermoreceptor that detects the temperature changes.
The other receptors like mechanoreceptor that respond to mechanical pressure, pain receptors respond to painful stimulus, chemoreceptors that respond to chemical changes and nociceptors that respond to threat stimulus are the part of somatic sensory system.
Answer:
It is A
since the energy source is the first thing you need to make the planet habitable, and in order for the animals to live, you need plants like trees to give air. so the cycle is Sun-Plant-Animal
When a cross between 2 contrasting parents produces a new phenotype, it is known as incomplete dominance. In diploid (2n) organisms, individuals receive one allele or gene variant from each parent.
Heterozygous individuals carry different alleles for the same gene <em>locus</em>.
Incomplete dominance occurs when both alleles are expressed in heterozygous organisms.
The phenotype in cases of incomplete dominance is a mixture of the phenotype observed in both parents.

Bacteria play a role in the nitrogen cycle because:
The bacteria’s helps in breaking down the organic materials which has nitrogen in it, and helps in giving the nitrogen back to the cycle. Bacteria helps in breaking down of the leaves and then it diffuses the nitrogen to the soil. Prokaryotes also plays an important role in the nitrogen cycle. The nitrogen fixing bacteria present in the root zone of plants basically in the soil, helps in conversion of the nitrogen into ammonia. Then the nitrifying bacteria converts the ammonia to the nitrites or can say nitrates.
