Answer:
The Natural Step Framework is a methodology for successful organisational planning. It is based on systems thinking,
recognizing that what happens in one part of a system affects every other part. We begin by understanding the broader system
within which problems occur and the principles governing success within that system These principles for success then
provide a practical set of design criteria that can be used to direct social, environmental and economic actions, developing
effective, durable solutions to the environmental, social and economic issues of the new century.
Explanation:
Genetics is the scientific study of genes and heredity—of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence. A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work.
Answer:
OH, H2O2 and O−2
Explanation:
Reactive oxygen species (ROS) can be defined as highly reactive chemical compounds formed from molecular oxygen (O2). ROS are generated as a normal product of cellular metabolism, and also as a response to different environmental/internal cellular stimuli (e.g., cytokines, xenobiotics, pathogenic invasion). For example, hydroxyl radicals (·OH) are a type of ROS generated in the mitochondria which are capable of inducing oxidative stress in different cells and also trigger chronic inflammation. Moreover, hydrogen peroxide (H2O2) molecules represent another type of ROS which are produced during the stereoselective deamination of amino acids, i.e., the building blocks of proteins. These molecules (H2O2) exhibit toxic effects on the cell (e.g., DNA damage). Finally, singlet oxygen (1O2) is an excited state of molecular oxygen (O2) that is generated during photosynthesis in the photosystem II (PSII) of chloroplasts.
ATP synthesization - Simple and complex lipids or carbohydrates are used to produce ATP through redox reactions. After the hydrolysis of complex carbohydrates, glucose and fructose are formed and the triglycerides are metabolized to form glycerol and fatty acids. ATP is then synthesized by oxidative phosphorylation and photophosphorylation during the energy production with in the living organisms. ATP production usually takes place in the mitochondria of the cell. The important pathways by which ATP is generated are glycolysis, the citric acid cycle (or the Kreb’s cycle), and the electron transport chain (or the oxidative phosphorylation pathway). In these three cycles of cellular respiration adenosine diphosphate (ADP) is converted to ATP and energy is released from molecules.
False there may be two or more dependent variables in a well designed experiment
