True. Think if ice cubes in the freezer. They shrink due to sublimation. <span />
A macrophage is a large phagocytic cell that engulfs foreign particles and pathogens. So Macrophage.
Hope this help! :)
Answer:
Photosynthesis removes CO2 from the atmosphere and replaces it with oxygen.
Explanation:
Photosynthesis removes CO2 from the atmosphere and replaces it with oxygen. By respiration, O2 is removed from the atmosphere and replaced with CO2. However, these processes are not balanced. Some organic matter is not oxidized. (I'm very sorry if I'm wrong but I believe it's that)
Answer:
q1 : ribosomes because they are responsible for protein synthesis
q2 : by transporting potassium ions into the cell and sodium ions out of the cell maintaining a concentration gradient
q3 : seawater contains a high concentration of sodium and chlorine ions that the Atlantic cod gets rid of by actively transporting them out of its body
Answer:
The conditions that would cause a molecule to diffuse from outside to inside of a structure is a higher concentration of that molecule outside and the presence of a semipermeable membrane that facilitates its passage.
Explanation:
The process by which a molecule passes from a place where it is more concentrated where its concentration is lower - crossing a semipermeable membrane - is called simple diffusion.
<u>Simple diffusion is a mechanism that does not require energy and responds to a concentration gradient</u>. When a molecule is more concentrated in a space it can enter the space where it is less concentrated
.
The cell membrane is an example of a semi-permeable membrane where the simple diffusion process occurs.
