In pea plants, round peas (r) are dominant to wrinkled peas (r). you do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. you end up with three plants, all which have round peas. from this data, can you tell if the parent plant is homozygous dominant or heterozygous?

During the process of meiosis, special cells called gametes are formed. gametes only have half the number of chromosomes that the other cells in the body have. what form of reproduction do organisms that produce gametes use?

What volume of a 0.25 m solution can be made using 0.55 moles of ca(oh)2

(me out over the last several centuries, scientists have made the following broad observations while investigating several branches of the life sciences: -the fossil record shows that different types of organisms have existed at different times in earth's history. -many organisms have similar body structures that seem to be adapted to different ways of living in their environment. -organisms of different species often share similarities in stages of embryonic development. -many species share genetic similarities, and almost all organisms use the same basic building blocks to construct proteins. -often, the extent of two species' similarities can be predicted from their geographic closeness to each other. -a great deal of change has been observed among species that have experienced strong selective pressures through many generations. scientists have carefully considered and rigorously tested the observations listed above. when scientists offer a of these observations, they are making 1.) testable explanation, deductive explanation 2.) scientific interference, scientific law
