Answer:
The correct answer is Suprachiasmatic nucleus
Explanation:
Melatonin is a hormone secreted by the pineal gland which plays a major role in sleep regulation in humans. This hormone is majorly secreted at the night time when the light entry reduces in eyes.
The Suprachiasmatic nucleus of the anterior hypothalamus regulates the release of melatonin by the pineal gland in the night by getting the low light signal from the optic nerves. By controlling the secretion of melatonin Suprachiasmatic nucleus controls the sleep-wake cycle in humans. So the correct answer is the Suprachiasmatic nucleus.
1. Genetics and environment influence the trait as it depends upon the adaptation made according to availability and environment.
2. Traits are passed onto either parents after fertilization when 2 genes from either parent is received.
3. Dominant trait is responsible for the phenotype of the individual.
4. The expression of gene is seen by the phenotype expressed depending upon the environmental factors.
Explanation:
The food preferences are based on the traits adapted over the time for digestion and method of eating due to natural selection. The occurrence of beneficial trait for digestion become common in the population as these traits are transferred for better survival and evolution.
The traits in an organism is passed on from parents. During fertilization one allele from each parent is passed onto the progeny. 2 alleles together are called gene. In the process of meiosis only one chromosome is present in germ cell hence no homologous chromosome thus only one allele for the trait is present in each parent.
The alleles of dominant trait mask the effect of recessive alleles during phenotype expression. According to law of complete Dominance the dominant trait gets expressed and recessive trait do not get expressed.
The temperature, external environment, chemicals, light factor, diet etc influences the expression of genes in certain organisms. The effect of these can be seen on the phenotype of the organism.
Answer:
nature and nurture
Explanation:
According to my research on studies conducted by various developmental psychologists, I can say that based on the information provided within the question they believe that development is the result of nature and nurture working together. This is because they believe that these two categories are correlated, therefore an event in one can affect the other and vice versa.
