Sea otters affected biodiversity because they control the
populations of sea urchins, which endanger kelp forests. Kelp
forests are important because they convert sunlight to living material, and
they also provide food and habitat to sea creatures. Kelp is important in
sustaining the diversity of ecosystems. Additionally, sea otters may also be accountable
for the large size of abalones in California.
This is where diffusion happens down the concentration gradient i.e. from high to low concentrations (just like simple diffusion) but facilitated diffusion requires a special and specific protein within the cell membrane. The substate binds to the receptor and the receptor itself changes conformation so that the substrate is now on the other side of the membrane. This is done for molecules that are too large to pass straight through the phospholipid bilayer (cell membrane) by simple diffusion e.g. glucose.
Ayo i think the answer is B, 10 mg/l. bc you would label the respiration rate as R, we come up with a neat little formula: NPP = GPP - R. hope this helps, have an amazing day :)
11 is b but I don’t know the rest sorry
They have to find different food because its normal choices of food arent avalible during cold tempatures. They have to go into hiding and prepare for this change.
