<span>The presence of rigid cell wall that gives the block like structure to the plant cells which is not the case with the animal cells which has soft membranes. Another reason for this kind of maintenance of plant cell shape is that the network of fibers that are present in the cytoplasm called as Cytoskeleton.</span>
Benefits:
-Wind doesn’t cost anything so, operational costs are close to zero
-Doesn't pollute the air or create any harmful chemicals
Costs:
- Visual and noise pollution, they take up space and are very noisy
- Can be harmful to wildlife such as birds
A) heat is related to speed/ energy of molecules so when it is decreased the molecules slow down and stop bouncing around/ loose energy
Answer:
The correct answer is both pumps use proteins to transport substances across the cell membrane.
Explanation:
Sodium potassium pump helps in the active transport or uphill transport of both sodium and potassium across the cell membrane against their concentration gradient.
Whereas Ca2+ATPase or calcium pump itself is a trans membrane or membrane spanning protein which helps in the transport of Ca2+ outside the cell to maintain electrochemical potential of Ca2+ ions.
