Tissue damage activates nociceptors or pain receptors in the skin. A signal is sent to the peripheral nerve to the spinal cord where neurotransmitters or chemical messengers are released. It activates other nerves to pass signal to the brain. The signals are relayed to the somatosensory cortex for sensation, frontal cortex for thinking and limbic system for emotional response.
Answer:
This suggests that the round wing fruit flies are more adapted to live in the environment as compared to the curled wing fruit flies. Also, this suggests that round might be the dominant trait over the curly trait. This is because a dominant allele can show its trait even when both the alleles of a gene are different or heterozygous. On the other hand, a recessive trait will only be seen when the alleles will be the same and recessive type.
C.Central nervous system effect
Answer:
In the fungal life cycle, karyogamy results in D. fungi haploid nuclei from two parent fungi fuse together
Explanation:
Karyogamy has an important role in sexual reproduction. It is the last step in the process of fusing together two haploid eukaryotic cells, and refers specifically to the fusion of the two nuclei. This is the steps that usually follows the Plasmogamy stage. This step is part of the sexual reproduction of fungi too. Karyogamy is key because it helps recombine two different genetic material.
