Explanation:
Answer: light energy to convert carbon dioxide and water into glucose and oxygen gas
Answer:
B. The hydrogen and oxygen atoms in water share their electrons; sodium transfers an electron to chlorine in sodium chloride.
Explanation:
The bonds between sodium and chloride in NaCl (table salt), and oxygen and hydrogen in water are different as sodium and chloride in NaCl have ionic bond and oxygen and hydrogen in water have the covalent bond.
Sodium transfers an electron to chlorine in sodium chloride (NaCl), so that they both have full outer shell and form ionic bonds. sodium and chloride ions exerts electrostatic force on each other and bond together with ionic bonds.
The hydrogen and oxygen atoms in water have covalent bonds because they are bonded by sharing electrons. Both hydrogen and oxygen atoms share unequal electrons with each other and form V-shaped water molecule.
Hence, the correct answer is "B."
Cellular respiration
Explanation:
The release of energy in living thins is known as cellular respiration.
In the process of cellular respiration, oxygen combines with sugar and thereby releasing energy in form of ATP(Adenosine Triphosphate) and carbon dioxide. ATP is the store house energy in the cells and during respiration, this compound is synthesized.
The sugar is produced in the process of photosynthesis in plants using carbon dioxide and water in the presence of sunlight.
