The answer would be an example of adaptation i’m pretty sure .
<span>Elements like carbon, nitrogen and oxygen are present in great quantities in the biosphere. They are critical for the existence of life.
A gas that contributes to the greenhouse effect by absorbing infrared radiation, e.g., carbon dioxide and chlorofluorocarbons by absorbing infrared radiation causes an increase in global atmospheric temperature</span>
Answer: The rate of diffusion is directly proportional to the molecular weight of any gaseous substance
Explanation:
According to Graham's law of diffusion, the rate of diffusion is directly proportional to the molecular weight of the gaseous substance.
Hence, the lighter the molecular weight, the faster the diffusion.
Answer:
Natural selection is defined as what?
Natural selection entails the ability of an organism to adapt to an environment and such adaptive traits are passed from parents to offspring
Explanation:
The law of natural selection was propounded by Charles Darwin which entails the survival of an organism by adapting to an environment and such adaptive trait is passed to offspring
The most used instruments for the determination of free-living physical activity and energy expenditure are; whole-room indirect calorimeter, Accelerometers and pedometers and also the Doubly-Labeled Water. Indirect calorimetry measures gas exchange from which energy expenditure can be estimated, Double labeled water is the most relevant method for measuring free-living energy expenditure in animals and humans, it is based on exponential disappearance from the body of the stable isotopes (H and O) after a bolus dose of water. Accelerometers and pedometers provide an inexpensive overall measure of physical activity, however they are unable to asses the intensity, frequency and duration of activity or to estimate energy expenditure.
