Methods
Mice were used in this experiment. Two groups of mice were studied, the experimental group, which was exposed to ETS, and the control group, which was not exposed to ETS.
Gene Environment Interaction
Gene environment interaction is an influence on the expression of a trait that results from the interplay between genes and the environment.
Environmental origin of traits
The environment plays a large role in the determination of traits. This is natural as all organisms must have input (and output) of energy and matter in order to maintain their overall elevated energy state.
Environmental factors that affect the rate of transpiration
1. Light
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism).
environment -- The place in which an organism lives, and the circumstances under which it lives. Environment includes measures like moisture and temperature, as much as it refers to the actual physical place where an organism is found.

Environmental Factors
Several environmental factors affect one's probability of acquiring cancer.
Environmental variance
Within a population, the measure of how much of the variation of a particular phenotype is due to environmental factors (as opposed to variations in genotype - see genetic variance).
Environmental condition under which a conditional mutation shows the wild-type phenotype.

The environment is the ultimate cause of population stabilization. Two categories of factors are commonly used: physical environment and biological environment.
The environment, workplace pollutants and natural causes play a role in the rest.

An environmental condition that results in a phenotype different that that usually observed for a certain mutant.
The Beaver Uses His Environment To Build A Dam.
All life forms have different needs. For example, most fish do not fly, and most birds do not swim, while most plants don't do either.
(2) The location or environment where an organism (or a thing) is most likely to be found, e.g. the body part of the host of a parasite as in the scalp of the host is the habitat of a head louse.
The wide diversity and interrelatedness of earth organisms based on genetic and environmental factors. Bioenrichment. Adding nutrients or oxygen to increase microbial breakdown of pollutants. Biofilms. See Microbial mats. Biologics.
Multifactorial -- a characteristic influenced in its expression by many factors, both genetic and environmental. Mutation -- process by which genes undergo a structural change.
Ecology: the science that studies the relationships between organisms and their environment. "The study of the structure and function of nature" (Odum, 1971--Fundamentals of Ecology).
Recombinant DNA technologies Procedures used to join together DNA segments in a cell-free system (an environment outside a cell or organism).
The ability of proteins to fold to their functional states following synthesis in the intracellular environment is one of the most remarkable features of biology.
The video "Roots of Discovery", primarily underwritten by National Science Foundation and NASA, and the National Space Development Agency of Japan explores plant sensory responses to various environmental signals, particularly gravity.
Inappropriate use of antibiotics (prophylactic treatment of herds in meat production and pointlessly treating viral infections with antibacterials) flood our environment with drugs that select for populations of antibiotic-resistant bacteria.
Every living thing interacts with other organisms and its environment. One of the reasons that biological systems can be difficult to study is that there are so many different possible interactions with other organisms and the environment.
Chromosomal DNA accumulates mutations at a predictable rate as a result of errors in replication and environmental mutagens, which are not corrected by DNA repair systems.
The cell is further safeguarded from exposure to the biochemical catalysts present in lysosomes by their dependency on an acidic environment. With an average pH of about 4.
Ecogenetics: The branch of genetics that studies how (inherited or acquired) genetic factors influence human susceptibility to environmental health risks.
Your respiratory system is all about exchanging gases with the environment. Some animals such as amphibians are able to exchange gases through their moist skin. Fish have gills while mammals, birds, and reptiles have lungs.
The study of how genomes respond to environmental stressors or toxicants.
Within a population, the measure of how much of the variation of a particular phenotype is due to genotypic variation (as opposed to environmental factors - see environmental variance).
Crassulacean acid metabolism An adaptation by plants living in arid environment; the C4 pathway concentrates carbon dioxide at night, and vapor exchange with the environment is curtailed during the heat of the day by closure of the stomata.
