How does the environment affect DNA?
While the sequence of DNA may not be affected by your environment, the way genes work—called gene expression—can. Environmental factors such as food, drugs, or exposure to toxins can cause epigenetic changes by altering the way molecules bind to DNA or changing the structure of proteins that DNA wraps around.
How do species become adapt to their environment?
This happens by the process of natural selection. By natural selection, the nature of the species gradually changes to become adapted to the niche. If a species becomes very well adapted to its environment, and if the environment does not change, species can exist for a very long time before they become extinct.
How does DNA adapt?
DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism’s genetic makeup, it can prove harmless, helpful, or even hurtful.
How does the environment determine genetic change?
Internal and external environmental factors, like gender and temperature, influence gene expression. Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes are turned on and off, thereby influencing the way an organism develops and functions.
How do environmental and genetic factors influence the growth of organisms?
How do environmental and genetic factors influence the growth of organisms? Genetic factors as well as local conditions affect the growth of organisms. − A variety of local environmental conditions affect the growth of organisms. Genetic factors affect the growth of organisms (plant and animal).
How do animals change their environment?
Animals make changes to the environment by eating. This helps plants grow in new places and changes their environment. Animals make changes to the environment by eating. When a macaw eats seeds, it will fly somewhere else and then eventually poop the seeds out.
Do genes change when animals adapt?
Through reproduction, genes are passed on to offspring. This passes down the genes coding for physical characteristics suited to the new environment. Over the course of several generations, the genetic make-up of a species will slowly change and their physical characteristics will adapt to the needs of the environment.
