Answer:
C.
Explanation:
only a few types of molecules pass through the cell membrane
The cell wall and chlorophyll are absent in animal cells. These are unique to plant cells.
Answer:
Feedback loop will fail in an ecosystem if the factors regulating the feedback mechanisms fail to function.
Explanation:
Feedback loop is the phenomena in which output is circled back in a way that it is used as input again i.e the reaction is circled back. Its a continuous process.
There are two types of feedback loops, positive and negative, one functions to reinforce and other functions to balance. Positive feedback loops enhance the outputs while negative lower the output and keeps the balance. the variables that are involved in all these processes effect each others so, by eliminating such variables or factors will cause failure of feedback loops.
36... The breakdown of one glucose results in 36 to 38 ATP molecules being formed; this is under 40% of the potential energy within a glucose molecule, over 60% is lost as heat.
ans2.sunlight ....a. Aerobic cellular respiration is a gradual process that prevents energy loss as heat.
ans3...6O2 + C6H12O6 yields 6CO2 + 6H2O + Energy
<span>because “Barrow is ground zero for climate-change science, and because we worry that climate change is shrinking the sea ice and we don’t know how that will affect the animals that depend on it. But at this time there is no effective plan if a catastrophe such as a ship collision or oil spill occurs. The Coast Guard hasn’t decided what its presence will be in the Arctic. Someone needs to monitor whats going on there.</span>
