The mechanical advantage of output force/input force comes from the grater distance the pulley rope moves. The work has to be the same, by conservation of energy: 50 x = (100)(45) where x is the distance the rope was pulled.
x = 90 cm
Only the strongest survive
Answer:
Additive alleles
Explanation:
Additive alleles account for the hereditary influence on the phenotype in a cumulative way.
Alleles are nothing but variations of a gene. that simply gives variation to the traits.
Whereas, Additive alleles are alleles that contribute to most observable traits, such as height, weight, hair color, eye color,and complexion. Therefore, they account for the hereditary influence on the phenotype.
Each upward movement of the basilar membrane causes the stereocilia of the inner hair cells to bend, opening K+ gates.
