Answer:
The tall parent was heterozygous
Explanation:
If tall height is dominant to short height the only genotype possible for short height is hh, while there are two possible genotypes for tall height, Hh and HH. When HH is crossed with hh all the offspring are Hh, but if Hh is crossed with hh, a quarter of the offspring is HH, a quarter is hh and half is Hh. If the tall pea plants were HH there would only be tall offspring, but because there are some short offspring we know that the tall pea plants must have a genotype of Hh.
Answer:
The correct answer is option d)"the percentage of pink flowers should increase over time".
Explanation:
In this study it is stated that two factors affect the flower coloration of <em>Claytonia virginica</em>: slugs preference of eating pink-flowering plants and bees preference of pollinating pink-flowering plants as well. If the researcher removes all slugs from the study population we can expect that the percentage of pink flowers should increase over time. The removal of the predator that prefers eating pink-flowering plants will favor the reproduction of this type of plants, which are also favored by bees pollination preference.
A frog gets rid of it's urine through the kidneys because the heart pumps blood throughout the body, the lungs are used to take in O2 molecules and gills are use to filter out the hydrogen in HO2 so they can breathe under water. However the kidneys are part of the waste disposal system (what makes us need trip to the bathroom ever now and then) therefore that is the answer.<span />

Answer:
D. the process by which species change as successful traits are passed on to the next generation
Explanation:
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
