It is helpful to form hypotheses because they help focus your investigation on a single idea to be tested. Suppose that a farmer wants to determine what the best growing conditions are for almond trees on his farm.

Which of the following are appropriate hypotheses that the farmer could test?

A. Almond trees live longer if fertilizer is mixed into the soil once every three months.
B. Almond trees produce larger almonds if they are watered daily and fertlizer is used
C. Almond trees grow taller when they are planted in direct sunlight
D. Almond trees produce more almonds if they are watered once a day.

Apuppy’s tendency to chew is inherited through which of the following? a. through learned behavior b.through genes c. through seasonal cycles d. through hibernation

Aspecies has evolved an asexual mode of reproduction by having offspring develop from unfertilized eggs. which of the following will be true of this species' response to natural selection? there will be more deaths from natural selection because there is no mutation. there will be less genetic variation from recombination and a risk of not adapting quickly to environmental change. the species will increase in numbers because genetic variation is increased. the species will compensate for loss of genetic variation by hybridizing with other species. there will be fewer deaths from natural selection because sexual recombination always leads to extinction.

What do well call it when two or more genes determine an organisms trait? a.polygenic b.controlled by one gene c.mutated
