I believe the answer is C.
because when the dinosaurs thrived they ate most of the mammals which were small animals but when the dinosaurs went extinct the mammals grew larger in size and started to thrive.
All of them are correct soil erosion turns grains of soil into mere grains of sand which when placed in water makes the water much cloudier, biodiversity will decrease as soil erosion leads to a more Barron and dry landscape, respiratory disease may be caused by inhaled particles of dust which can be create from soil erosion, and desertification as mentioned earlier soil erosion leads to a more baron and dried out landscape as the soil can’t hold water as much as it used too.
<u>Answer:</u>
C is the answer.

<u>Explanation:</u>
Organelles (the smallest in this situation) are what you can find inside a cell (example: nucleus, mitochondria, etc..).
Cells are what make up tissues (such as muscles).
Tissues make up organs (such as the heart) and organs make up organ systems (such as the circulatory system).
Answer:
Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.
Explanation:
undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.
Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.
Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.
