The expression of genes in an organism can be influenced by the environment, including the external world in which the organism is located or develops, as well as the organism's internal world, which includes such factors as its hormones and metabolism.
What environmental factors can cause autism?
Scientists use the term "environmental" to refer to influences other than changes in a gene's DNA. Autism risk factors, for example, appear to include such influences as parental age at conception, maternal nutrition, infection during pregnancy and prematurity.
Examples of environmental factors include soil, water, climate, natural vegetation and land forms. Environmental factors entail everything that changes the environment. Some factors are visible, while others cannot be seen. Environmental factors may affect living things either directly or indirectly.
Over the past 100 years, the study of environmental influences on human physical growth and development has focused on the influences of social and economic factors; family and household characteristics; urbanization/modernization; nutrition; and features of the physical environment such as altitude, temperature and
A child's early home environment has long-term effects on development. The home environment can even affect a child's brain development. A risk factor is a condition that is statistically associated with a given outcome. They are said to be at risk because as a group they have a higher incidence of dropout.
Inherited traits are traits that you get from your parents that are influenced by your genes. Environmental. traits are influenced by your environment (you can learn them or control them).
Factors influencing growth & development:
- Genetic. Certain hereditary factors influences on the body formation.
- Nutritional. Nutritional deficiency considerably retards physical growth.
- Socio Economic Condition:
- Environmental & seasonal.
- Chronic diseases:
- Emotional & cultural.
- Growth potentials.
Phenotype. Phenotype is the observable physical or biochemical characteristics of an individual organism, determined by both genetic make-up and environmental influences, for example, height, weight and skin colour.
the aggregate of surrounding things, conditions, or influences; surroundings; milieu. Ecology. the air, water, minerals, organisms, and all other external factors surrounding and affecting a given organism at any time. the social and cultural forces that shape the life of a person or a population.
Your hereditary traits affect your functioning within your environment, and your environment affects the development and expression of your inherited traits. Your personality development is also affected by your surroundings, 2-1. Environmental factors that influence personality will be studied in this chapter.
[Effect of environmental chemicals on the genes and the gene expression]. Chemicals act on biological molecules and affect their functions. DNA is one of the most important targets, damaging of which could lead to diverse diseases including cancer. Second, a group of chemicals called endocrine disruptors is described.
Environmental factor or ecological factor or eco factor is any factor, abiotic or biotic, that influences living organisms. Abiotic factors include ambient temperature, amount of sunlight, and pH of the water soil in which an organism lives.
Environmental, economic, social and political factors affecting development – global imbalance of trade between different parts of the world.
- Environmental factors affecting development – the impact of natural hazards.
- Economic factors affecting development.
- Social factors.
Environmental psychology is an interdisciplinary field that focuses on the interplay between individuals and their surroundings. The field defines the term environment broadly, encompassing natural environments, social settings, built environments, learning environments, and informational environments.
Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.
Business is affected by different factors which collectively form the business environment. These include economic, social, legal, technological and political factors. Business environment is therefore, the total of all external forces, which affect the organization and the business operations (Kotler &Armstrong 2004).
Hereditary mutations are inherited from a parent and are present throughout a person's life in virtually every cell in the body. These mutations are also called germline mutations because they are present in the parent's egg or sperm cells, which are also called germ cells.
Published on 4 November 2010 (and updated on 10 June 2011), the 2010 Human Development Index (HDI) combines three dimensions:
- A long and healthy life: Life expectancy at birth.
- Education index: Mean years of schooling and Expected years of schooling.
- A decent standard of living: GNI per capita (PPP US$)
Inheritance of Traits by Offspring Follows Predictable Rules. Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.
Height, hair color, eye color, facial features, and more can all be inherited traits. You have no influence on what traits you inherit. There is debate about whether personality traits and behaviors can be inherited, or whether they are learned through environmental exposure.
Epigenetic inheritance is an unconventional finding. It goes against the idea that inheritance happens only through the DNA code that passes from parent to offspring. It means that a parent's experiences, in the form of epigenetic tags, can be passed down to future generations.
