The right answer is Electromagnetic waves can transfer energy through empty space.
Electromagnetic radiation refers to a form of linear energy transfer. Visible light is electromagnetic radiation, but is only a small slice of the broad electromagnetic spectrum. The propagation of this radiation does not need material to move.
if we take the example of solar energy, it spreads in space, the atmosphere until reaching the earth.
Once it reaches a material, it gives rise to many phenomena such as attenuation, absorption, diffraction and refraction, redshift, interferences, echoes, electromagnetic parasites and biological effects.
Answer:
See the answer below
Explanation:
<em>Both conclusions can be valid because they are based on valid data and scientific reasoning.</em>
In order for a data to be valid in making a conclusion, such data must have been collected through a scientific experiment that is devoid of subjectivism. In order words, the data must have been objectively collected via standard experimental procedures.
Once data have been collected, they are analyzed and used to make valid conclusions based on the hypothesis which must have been made earlier before the experiment.
Conclusions made from standard experimental procedures and scientific reasonings are valid and such experiments are reproducible.
<em>Hence, as long as the data from which the conclusions were made can be reproduced through the same experiments, the conclusions are valid.</em>
Obsidian is sedimentary and basalt is igneous
Answer: B). NADH and ATP
Explanation: Glycolysis is a ten enzyme catalyzed reaction in which glucose a six-carbon sugar is broken down into two molecules of three-carbon pyruvate. Glycolysis is divided into two phases: the preparatory phase constituted by the first five reactions and the pay off phase constituted by the remaining five reactions. Energy-carrier molecules are produced in the pay off phase. In this phase, four molecules of ATP and two molecules of NADH are produced. NADH is produced in a reaction catalyzed by glyceraldehyde 3-phosphate dehydrogenase in which glyceraldehyde 3-phosphate is converted to 1,3-Bisphosphoglycerate. ATP are produced in a reaction catalyzed by phosphoglycerate kinase in which 1,3-Bisphosphoglycerate to 3-phosphoglycerate, and in a reaction catalyzed by pyruvate kinase in which Phosphoenolpyruvate is converted to pyruvate.
False, the description is incorrect.
The only right answer is oil or lipid or fats. These lipid macromolecules are the only substance needed in order for these vitamins A, D E and K to be absorbed by the cell and be used in many cellular activities.
