Suppose that an allele is present in pelican offspring that causes a nestling to share its food with its nestmate if it is not particularly hungry. this gene imposes a fitness cost of 0.2 on those who carry it, while conferring a benefit of 0.5 on the sibling who receives the additional food. will this gene increase in frequency if two nestmates are always full siblings?

Imagine a person stepping on a pin and pulling his or her foot away. look at the reflex arc of this scenario below. which statement best describes the image? a)the sensory nerve carries the signal from the effector to the interneuron, and the motor neuron carries the signal to the receptor. b)the motor nerve carries the signal from the receptor to the interneuron, and the sensory neuron carries the signal to the effector. c)the sensory nerve carries the signal from the receptor to the interneuron, and the motor neuron carries the signal to the effector. d)the sensory nerve carries the signal from the receptor to the motor neuron, and the interneuron carries the signal to the effector.
