Environmental factors often influence traits independently of genes. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.
How do environment and gene determine our personality?
Some genes increase the characteristic and others work to decrease the same characteristic-complex relationship among the various genes, as well as a variety of random factors, produce the final outcome.
Because of their genetic makeup, individuals differ in their responsiveness to the qualities of the environment. There are unique, genetically influenced reactions to particular experiences to which we are exposed.
The presence of drugs and chemicals in an organism's environment can also influence gene expression in the organism. The environment can affect morphological and physiological development whereas genes influence morphology and physiology, creating a framework within which the environment acts to shape the behavior of an individual.
Hence in this way, genes and environmental influences work together to determine our characteristics.

<span>Pesticide use is harmful to human agriculture because it
contains an antifreezing chemical (present in transportation vehicles). When
the chemical seeps into the leaves of the plant, it is distributed all over its
body and remains there. The chemical may still be present there when we are
going to the plant.</span>
Answer:
The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.
Explanation:
Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.
Answer:
A very short history of climate change research. The story of scientists discovering climate change is longer than many of us tend to imagine.
We’ve had a sense that what humans do might effect the climate since Antiquity.
