B) is the correct answer. The flu virus does not have the same genetic makeup each year as with each individual it infects its rapidly mutating.
Diffusion, facilitated diffusion, osmosis
Fruits with tiny hooks are most likely to be spread by animal hair.

Answer:
(B) Boreal owls range over larger areas in regions where food of the sort eaten by small mammals is sparse than they do in regions where such food is abundant
Explanation:
Living beings exhibit various changes in the behavior and niche to make themselves better fitted to the conditions of their habitats.
Boreal owls feed on the other smaller mammals such as mice and shrews. These organisms that serve as their prey are relatively less abundant in the habitat. To ensure the food availability, the boreal owls occupy a larger area so that they can catch their less abundant food organisms.
In the habitats where the prey species of boreal owls are present in a larger number, these owls occupy smaller regions since the food organisms are easily available.
Answer:
1)
- frequencies of light-colored mice ≅ 0.74
- frequencies of dark-colored mice ≅ 0.26
2)
- frequencies of light-colored mice ≅ 0.13
- frequencies of dark-colored mice ≅ 0.87
3)
- q² = 0.74
- p² = 0.02
- 2pq = 0.24
4)
- q² = 0.13
- p² = 0.4
- 2pq = 0.46
5)
The dark-colored fur seems to have the greatest overall selective advantage
6)
Dark lava, that changed the color of the substrate, from light to dark.
7)
Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.
8)
To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.

Due to technical problems, you will find the complete explanation in the attached files.
