Answer:
B. Carbon dioxide
Explanation:
First of all, let’s write out the photosynthesis equation to identify the products and reactants.
6CO2 + 6H2O + energy —> C6H12O6 + 6H2O
In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.
In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.
Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.
We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.
Therefore, the best answer choice is B. Carbon dioxide
Find the sunny spot, dig and loosen up the soil, mix the nutrients, plants the seeds , and finally water them well.
Answer: A
Explanation: The nervous system sends electric signals from the brain to the body to make they move. The charger is similar becuase it sends energy to your devices so they can work.
Red blood cells have no mitochondria and generate energy anaerobic. So, the answer would be B. You can easily eliminate A. and C. because they mention that blood cells have a mitochondria, but they don’t.
