Why can't we normally detect the blind spot? - Answer Lack of photoreceptors in this area because it is where the optic nerve and blood vessels exit the eye. We cannot detect the blind spot because we use our surroundings to fill in the information with the ipsilateral and contralateral visual inputs Ideal Answer: The natural blind spot in the eye is due to the lack of photoreceptors where the optic nerve and blood ...

Why are there motor proteins associated with both actin filaments and microtubules but not intermediate filaments? - Answer Actin filaments and microtubules are highly polarized, therefore allowing motor proteins to form associations with them. Intermediate filaments are unpolarized and do not bind nucleotides such as ATP, leading to lack of motor protein associations (which are ATP driven). How does the hydrolysis of ATP cause myosin to move along the actin filament? - Answer ATP hydroly...
