2.
In fruit flies, a specific gene mutation causes the wings to become malformed. These wings are called vestigial because they do not function properly. The mutated allele for vestigial wings (v) is recessive to the allele for functioning wings (V). Two fruit flies that are heterozygous for wing shape are crossed, resulting in many offspring.
Which of the following would most likely describe the population of offspring?
Which of the following would most likely describe the population of offspring?
a)
About half of the offspring population has functioning wings, and the other half of the population has vestigial wings.
b)
The majority of the offspring population has vestigial wings.
c)
The majority of the offspring population has functioning wings.
d)
All of the offspring population have functioning wings.
3.
A potato plant can reproduce asexually so that one potato can often give rise to many other potatoes. Strawberry plants can reproduce sexually. A potato plant puts a large amount of its energy into growing a tuber, which is the part that humans eat. The tuber can grow large and provide energy for the plant during the winter, or it can be used to grow new potato plants. A strawberry plant, on the other hand, puts much of its energy into growing flowers to attract insects that aid in pollination. After fertilization, the strawberry plant must then also grow seeds as well as fruit to attract animals that disperse the seeds.
Based on this information, the asexually reproducing potato plant most likely devotes _______ to reproduction than the sexually reproducing strawberry plant.
Based on this information, the asexually reproducing potato plant most likely devotes _______ to reproduction than the sexually reproducing strawberry plant.
a)
less energy
b)
more energy
c)
fewer spores
d)
more seeds

Earth Today
(image)
The images above show how the Earth's continents looked 250 million years ago and how they look today. The change in the continents' positions is explained by the modern theory of plate tectonics.
The theory of plate tectonics developed in part from an earlier hypothesis about how continents move. What is the name of this earlier hypothesis?
