Plants add carbon to the atmosphere during respiration, and remove carbon through photosynthesis. These are two sides of the same coin – in photosynthesis, plants take in carbon dioxide and water, along with energy from the sun, to create glucose. In respiration, plants use oxygen to break down glucose for energy, releasing a byproduct of water and carbon dioxide.
Taken together, these processes form the carbon cycle, and it’s this cycle that’s been thrown into so much danger by human-driven climate change.
Answer:
Glucose is a six-carbon sugar that is directly metabolized by cells to provide energy. ... A glucose molecule is too large to pass through a cell membrane via simple diffusion. Instead, cells assist glucose diffusion through facilitated diffusion and two types of active transport.
Explanation:
Vultures obtain energy from scavenging.

16. Science is the study of the natural world by gathering information and data but technology needs science to create devices, ie. (phones, tablets, laptops).
17. Life and Earth.
18. A scientific law is the description of an observed phenomenon, and, the explanation of the phenomenon is therefore called the scientific theory.
19. 1.) ask questions.
2.) do a background research.
3.) create a hypothesis
4.) test your hypothesis with experiments and etc..
5.) review your data and create a conclusion.
6.) talk about your results, (what, why, how).
Good luck!
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
