Want this question answered?
because there is less oxygen in water meaning they have to be more efficient to get enough oxygen
Gills are more efficient at obtaining oxygen, but there is much more oxygen in air to breath through the lungs.
Amphibian lungs do not have to be as efficient as gills because there is much more oxygen in air than in water.
Glycogen is branched to allow more efficient energy storage and to provide multiple attachment points for enzymes that add to its glucose monomers.
The gills are feathery so it has more surface area, allowing more gas exchange! By gas exchange u mean to take in oxygen and let out carbon dioxide, right?
Amylopectin is a branched-chain polymer of glucose that is a component of starch, characterized by frequent branching points that create a highly branched structure. It can be broken down into glucose units for energy more quickly than amylose due to its branched structure. Amylopectin is less prone to retrogradation compared to amylose, making it more suitable for applications where a gel-like consistency is desired.
depends on how you look at it solar energy is more highly developed but hydro electric is more efficient when it is used
To acquire more oxygen from water as the large SA of the gills allow more water to pass through and thus more O2 from the water to transfer into the gill-bearing creature's bloodstream for respiration
It is not in our genetic code to have eight legs and arms. It would be very useless to have eight legs and arms, as two legs and arms is highly efficient, and more is not necessary to make the human more efficient.
Fishes having gills are more. Also some fishes have lungs.
More efficient and most efficient are the comparative and superlative forms of "efficient".
The cystalline branched polyethylene has got a complex structure than a linear polyethylene.
