The appropriate answer is a. the conversion of radiant energy to chemical energy. Plants use light from the sun to convert carbon dioxide and water to glucose. An important bi-product of this reaction is oxygen which is vital to all life on earth. When humans consume glucose and do work they are converting chemical energy into heat energy and mechanical energy.
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:
Venous blood
Explanation:
Arterial blood is carrying oxygen to tissues.....after delivering the oxygen it is venous blood and has less oxygen.
Your answer would be D, Photosynthesis
Hope this helps!
Answer:
A. volcanic ash layers were regularly interspersed between the sedimentary strata.
Explanation:
The discovery of a fossil is a moment of accomplishment for archaeologists, hence the date dating process begins and the older the relic the greater its value for paleontology. Chemistry is present in this process, more precisely the carbon element, but other elements can be used as uranium, lead, potassium and argon.
In the case of the fossils reported in the question, to assign absolute dates to fossils in this sediment core would be most useful if volcanic ash layers were regularly interspersed between sedimentary strata because it would separate sedimentation times and allow the use of more than one element. dating, making the search more complete and the date most credible.
