Answer:
However, graphene has far fewer electrons than copper, so in graphene the electrical current is carried by only a few electrons moving much faster than the electrons in copper." In semiconductors, a different measure, mobility, is used to quantify how fast electrons move.
Answer:
Explanation:
Assume that a student is given two different models of bacteria, with one model consisting of big bacteria and the other consisting of small bacteria. How can the student demonstrate the theory of endosymbiosis using the models?
Hello!
Homozygous offspring are offspring that have two capital or two lowercase letters or just one letter, while heterozygous offspring have one capital and one lowercase letter.
The ratio of Homozygous to Heterozygous offspring is 3:2.
Answer:
False
"The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".
Explanation:
The food we eat undoubtedly contains energy. This energy is stored in the bonds of the molecules that make up the food. However, the food undergoes the process of digestion to yield glucose (a sugar). This glucose sugar is used in the process of CELLULAR RESPIRATION to synthesize a form of chemical energy usable by cells called ATP.
ATP or Adenosine triphosphate is a molecule that stores chemical energy in living cells. It is the molecule that directly powers all of our cellular activities. Hence, the statement in this question is FALSE. The correct statement should be "The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".
