Because it is written. A popular tool used for motivation and commitment is the use of written contracts and often does not even need to be as lengthy as a contract. A slip of paper or even another writing surface has been shown to significantly increase the likelihood of committing to that action.
There is also premeditation involved when signing a contract or writing on a piece of paper. An individual has read and recognized the written words and then signed it according to a commitment to that act. As such there is a significant amount of thought put into the over procedure, and thus increases again the likelihood of an individual to be committed to completing those actions.
Aside from all the factors of motivation, the signing demonstrates commitment to the contract because that is fairly universally understood to be the way in which people recognize and formally commit to contracts. Whatever the context of the action, whether signing papers to buy a house or for a new job, the signing of the contract is the commitment of the individuals involved to complete the requirements within the contract. Although in this instance the healthier behavior most directly affects the individual who signs the paper.
Answer:
increasing
Explanation:
the sun is not bad for plants. In fact, it makes them grow. Its like without no food.
The answer is copper. Nonrenewable resources are those that cannot be readily/naturally replaced at rates that match those of consumption (an aspect that allow renewable resources to be sustainable). Copper are made deep in earth at very slow rates hence do not readily renew themselves. Organisms, on the other hand die, and are naturally replaced by offspring.
Answer:
the average percentage of energy lost as heat
Explanation:
An energy pyramid (also called trophic pyramid) is a graphical representation that exhibits how energy flows at each trophic level in a particular ecosystem. In an energy pyramid, it is possible to determine how much energy is available at each trophic level and how energy flows from producers (e.g., photosynthetic plants) to primary consumers (e.g., herbivores), then from primary consumers to the next trophic level (e.g., carnivores), and so successively to all major trophic groups (e.g., higher carnivores). During this chain, energy is lost as heat when it is transferred to the next level, and the average percentage of energy lost increases at each trophic level, thereby less and less energy is available to major trophic groups.
