Genetic Drift can result in the loss of where alleles I can decrease the size of the alleles genetic drift can also cause a new population to be genetically distinct from its original population which has led to the hypothesis that genetic drift plays a role in the evolution of new species
Explanation: it goes through metaphase
The distance from the Sun allows for the right amount of light absorption, allows the right intensity of heat, and the gravitational pull of the sun on the earth keeps it from going out into outer space.
Hope this helped :)
Answer:
B. atrioventricular (AV) valve
Explanation:
The function of the conduction system of the heart is to spread the electric signal and make the heart contract in coordinated timing. Conduction starts at SA node, then the AV node then will spread by bundle branches.
The atrioventricular valve is not part of the conduction system. The valve function is to keep the blood flow back. If the valve is broken and blood did flow back, it can make the heart need to do more work than usual.
