A The observed differences in plants height are due to genetics.
I think the answer would be protons
1.Water evaporates in the presence of sunlight.
(hydrosphere)
2.Volcanoes release a large amount of gases and other matter during eruption.
(lithosphere)
3.Lightning causes nitrogen molecules to be split and carried by rain.
(hydrosphere)
4.Plants release water vapor through their leaves during transpiration.
(biosphere)
Hope this helps!
Punnet squares are a useful tool for predicting what the offspring will look like when mating plants or animals. Reginald Crundall Punnett, a mathematician, came up with these in 1905, long after Mendel's experiments. Let's take a look at how Punnet squares work using the yellow and green peas example from im not sure about the tree by three thing but maybe this will help :)
The statement would be considered to be B. False, because genetic drift occurs when different genotypes in smaller populations have a chance of disappearance. This is due to the species either dying off or not reproducing with others, so the genotype doesn't spread to offspring, because the species didn't have offspring.
