The answer is directional selection
It is the mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction. The advantageous allele increases in frequency independently of its dominance relative to other alleles; that is even if the advantageous allele is recessive, it will eventually become fixed, changes the average value of a trait. Occurs most often under environmental changes and when populations migrate to new areas with different environmental pressures.

A. Crossing over between homologous chromosomes.
1. gravitational potential energy
Yes, motion energy (kinetic energy) is transformed into gravitational potential energy as the rock falls.
2..When we push a huge rock, there is no transfer of muscular energy to the stationary rock. Also, there is no loss of energy because muscular energy is transferred into heat energy, which causes our body to become hot. From the conservation of energy we know that energy can neither be created nor destroyed, it can only be transformed from one form to another.
3 When the rock starts rolling down the hill it has kinetic energy. When the rock gets to the bottom of the hill and stops, it is no longer in motion therefore it no longer has kinetic energy, the energy has been converted back into potential energy.
Potential energy is transformed to kinetic energy.

The answer is <span>C. glycolysis, Krebs cycle, electron transport</span>
Cellular respiration includes glycolysis, link
reaction, Krebs cycle, and electron transport chain (ETC), in that order. The
main function of ETC is a production of ATP. In this series of
oxidation-reduction reactions, electrons from the previous stages of cellular
respiration are taken and transported to the oxygen which is the final acceptor
of electrons. As the result, water and ATP are produced.
