1 process where a parent passes certain genes onto their children or offspring. Every child inherits genes from both of their biological parents and these genes in turn express specific traits. Some of these traits may be physical for example hair and eye color and skin color and carry risk disease too.

2 can also be caused by exposure to specific chemicals or radiation. These agents cause the DNA to break down. This is not necessarily unnatural — even in the most isolated and pristine environments, DNA breaks down

3 disease is a rare inherited disorder that damages the ability of nerve cells (neurons) in the brain to send and receive messages.

4 replacement of the particular enzyme that is missing. Limiting certain substances in the diet can help prevent the buildup of potentially toxic substances that are normally broken down by the enzyme.


1 The sum total of all surroundings of a living organism, including natural forces and other living things, which provide conditions for development and growth as well as of danger and damage.

2 The primary cause of environmental degradation is human disturbance. The degree of the environmental impact varies with the cause, the habitat, and the plants and animals that inhabit it.

3 the physical, chemical, and biological factors external to a person, and all the related behaviors.

  • Outdoor air quality
  • Surface and ground water quality
  • Toxic substances and hazardous wastes
  • Homes and communities
  • Infrastructure and surveillance
  • Global environmental health

4 Schools, homes and businesses all can play a role in reducing the carbon pollution in our environment (See greenhouse gas emissions). Pollution is not just plastics, but food waste is a major contributor to the harmful, environmental effects. Food rescue, recovery can make a difference .

Lifestyle choices

1 a choice a person makes about how to live and behave, according to their attitudes, tastes, and values.

2 Poor lifestyle choices, such as smoking, of alcohol, poor diet, lack of physical activity and inadequate relief of chronic stress are key contributors in the development and progression of preventable chronic diseases, including obesity, type 2 diabetes mellitus, hypertension, cardiovascular disease and several types of cancer.

3 - People who smoke, don't exercise, eat poorly, and drink alcohol are three times more likely to die from cardiovascular disease and nearly four times more likely to die of cancer, a new study finds.Such people also have an overall premature death risk equivalent to being 12 years older

4people are affected the exact same way by depression, there is no “one size fits all” treatment that cures depression. What works for one person might not work for another.
