Glycolysis can produce a limited amount of atp for the cell, and it does not directly require any oxygen. however, when oxygen is absent, glycolysis stops because no nadh is present in the cell no nad+ is present in the cell no adp is present in the cell no fad is present in the cell

Amale bird-of-paradise uses a dance to attract mates in which it flaps its tail feathers on the ground and jumps around a potential female mate. a different male bird-of-paradise does a similar dance but it jumps around the female in the opposite direction. the female bird is only attracted to one style of dance, in one direction. this is an example of speciation.

In a cross between individuals of a species of tropical fish, all of the male offspring have long tail fins, and none of the females possess the trait. mating two of the f1 fish fails to produce females with the trait. explain the inheritance pattern of the trait.
