The correct answer is D: Group 4.
A control group in an experiment is a group separated from the other groups, where the variable that is being tested cannot influence the results. In this case, different materials are the independent variable that you test. Effects of that independent variable on the melting rate of ice are excluded in the control group.
Complete question:
In a population of flowers growing in a meadow, C1 and C2 are autosomal codominant alleles that control flower color. The alleles are polymorphic in the population, with f (C1) = 0.7 and f (C2) = 0.3. Flowers that are C1C1 are yellow, orange flowers are C1C2, and C2C2 flowers are red. A storm blows a new species of hungry insects into the meadow, and they begin to eat yellow and orange flowers but not red flowers. The predation exerts strong natural selection on the flower population, resulting in relative fitness values of C1C1 = 0.30, C1C2 = 0.60, and C2C2 = 1.0. Assuming the population begins in H−W equilibrium, what is C1 allele frequency after one generation of natural selection? Express your answer using three decimal places.
Answer:
The C1 allele frequency after one generation of natural selection equals 0.559
Explanation:
Due to technical problems, you will find the complete answer and explanation in the attached file.
Answer: Migration, because species move to other places for food or a better or more suitable habitat and sometimes their is other species there.
It would be scarce during a drought because in order for precipitation to take place evaporation must first occur. If there is to water to be evaporated then precipitation won’t take place
