During meiosis crossing over occurs at the pachytene stage, when homologous chromosomes are completely paired. At diplotene, when homologs separate, the sites of crossing over become visible as chiasmata, which hold the two homologs of a bivalent tighter until segregation at anaphase.
The white car finished first, and the blue car finished last because the white had the least amount of time. then, the blue car had the most amount of time. the speed would be 3 seconds because it is in between 2 and 4.
A single point mutation<span> can change the whole DNA sequence. Changing one purine or pyrimidine may change the amino acid that the nucleotides code for.</span>Point mutations<span> may arise from spontaneous </span>mutations<span> that </span>occur<span> during DNA replication.</span>
So that they can adapt to the situations that surround them in their environments.<span />
Answer: Tension
Explanation: Fault-block mountains are formed by the movement of large crustal blocks along faults formed when tensional forces pull apart the crust. Tension is often the result of uplifting part of the crust; it can also be produced by opposite-flowing convection cells in the mantle.
