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".
Answer:
B. Bacteria can exchange genes for resistance to antibiotics in this way.
Explanation:
Even though conjugation requires cell-to-cell contact, it can occur between distantly related bacteria
Answer:
the purple circles are the nucleus
B) high specific heat - strong hydrogen bonds require more energy to break
c) high boiling point - strong intermolecular forces
d) surface tension - strong molecule attraction
f) low solid density - hydrogen bonding means ice less dense than liquid
h) high heat of vaporisation - strong hydrogen bonds require higher energy to break bonds and change phase
