Answer:
True
Explanation:
Sound waves need a medium to travel through. That's why you cant hear sound in space. But you can see light in space and the sun heats up our planet, so yes, light doesnt need a medium to travel through.
Answer:
Components of the electron transport chain (ordered by electronegativity from least electronegative to most electronegative):
NADH dehydrogenase >> Coenzyme Q >> Cytochrome b-c1 complex >> Cytochrome c >> Cytochrome oxidase complex > O2
Explanation:
The electron transport chain transfers electrons from donors to acceptors via redox reactions (i.e., where reduction and oxidation occur together), and couples the transfer of electrons with proton transfer (H+ ions) across the membrane. In the electron transport chain, the electrons are transferred from NADH dehydrogenase NADH to oxygen (O2) through a series of transmembrane complexes: NADH-Q oxidoreductase, Q-cytochrome c oxidoreductase and cytochrome c oxidase. In the first place, the reduced form of coenzyme Q (ubiquinone) transports the electrons from the NADH-Q oxidoreductase to the Q-cytochrome c oxidoreductase complex (Cytochrome b-c1 complex). Second, the cytochrome c transports the electrons from this complex (i.e., Cytochrome b-c1 complex) to the Cytochrome oxidase complex, this being the last component in the electron transport chain that is responsible to catalyze the reduction of O2.
Pandas only blink sometimes because they are looking out for danger most of the time. Like other mammals, they have an upper and lower eyelid, so yes they do blink, but not as much as humans.
Answer:
So when the first animals moved onto land, they had to trade their fins for limbs, and their gills for lungs, the better to adapt to their new terrestrial environment
Explanation:
Answer:
Explanation:
Mutualism is a type of relationship where the organism involved both benefit from the relationship. This so true of tapeworms and shrimp as the infection caused by tapeworm on the shrimp bring about longetivity of the shrimp because it help them to survive in water containing arsenic toxins. Tapeworm lives on it host the shrimp and shrimp also benefit from tapeworm through its infection.
