Light, H2O, CO2 -> photosynthesis -> glucose, O2 -> cellular respiration -> ATP -> muscle contraction -> win
<span>Usain Bolt can run the 100 meter dash in record time because of this explanation and this will be the answer.</span>
<span>So based on your solution its letter A.</span>
Yes but cells also help get life to where it is right now and cells will also be changing genes connect with who we are and what we are and without those genes and cells we wouldn't be who we are today. genes do regulate mitosis but not for aerobic respiration genes give use our characteristics like girl,boy. DNA does help repair genes like per say you got a scrape on your leg or arm the DNA would clot so that the bleeding would stop and that would cause it to scab over.
<span>Genetic variation can be caused by mutation (which can
create entirely new alleles in a population), random mating, random
fertilization, and recombination between homologous chromosomes during
meiosis (which reshuffles alleles within an organism's offspring)</span>
