The f1 generation may have genes for short plants just that the genes for long plants are dominant over the genes for short plants(recessive) so when cross pollination happen and that two f1 long plants which are homozygous cross pollinate, the recessive genes have a chance of being paired up in new offspring(F2 offspring) thus the possiblity of short plants in f2 generation
I believe studying the hydrosphere would be most important because we haven't explored a good majority of it yet so we need to explore our waters before we explore space
Transduction. Transudction is the process where foreign DNA is introduced into a cell by a virus or viral vector. An example would be a viral transfer from one bacteria to another.
The first answer is right because the resource may take billions of years to replenish and us humans can’t wait that long. A example of a nonrenewable resource is fossil fuel it doesn’t mean it will be forever gone it will just be gone for a looooooooong time
