Muscle contraction that results in a change in joint angle is called <span>concentric contraction.
This contraction occurs when enough force that can overcome the resistance applied is developed by the muscle where this force developed is larger than the force of the resistance applied.</span>
It’s where a male or female chooses the opposite gender to be a mate for specific features. Ex.) peacocks choose makes with brighter feathers
Microevolution is a change in the frequency of gene variants, alleles, in a population, typically occurring over a relatively short time period.
Population genetics is the field of biology that studies allele frequencies in populations and how they change over time if this doesn’t (I hope this is right if It don’t know what will)
