Hmm, let me see. This illustration appears to be an image of a cell. But, there aren't any answers that has cell. Using logic, it would be an organelle. Mainly because there aren't any arrows directing to a specific organelle. Since a cell wall is an organelle, it has to be D.
Answer:
Cellular respiration moves carbon from the atmosphere to geosphere.
Answer:
Enzymes are biological catalysts that increase the rate of chemical reactions inside cells by lowering the activation energy required for the reaction to proceed. In nature, exergonic reactions do not require energy beyond activation energy to proceed, and they release energy.
Answer:
Facilitated Diffusion
Explanation:
Some molecules can move down their concentration gradients by crossing to the lipid portion of the membrane directly,while others must pass through membrane protein s in a process called Facilitated Diffusion
Answer:
4
Explanation:
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
