Activation energy is required to start a chemical reaction. Activation energy is the energy needed to allow the reactant to react. Activation energy is measured in Joules (J).
Crossing over occurs at the four-strand stage when two homologous chromosomes, each consisting of a pair of sister chromatids, are paired. Each crossover involves just two of the four strands and generates two recombinant strands.
Hope this helps!

The shape a coyote brush takes depends on the location in which it is growing, but each coyote brush plant develops a large root system that extends outward many yards from the main plan
Answer:

If we draw a Punnett square, we can see that some of their children will inherit the trait while others will not.
