Answer:
A) Any butterfly allele that allowed milkweed toxin storage would be likely to persist because butterflies that had it were more likely to survive.
Explanation:
Butterflies are natural preys to birds. Over time, some butterflies evolved adaptive strategy such as developing an allele which enables storage of toxin from milkweed as a form of defense mechanism. This stored toxins repel birds from eating the butterflies having this allele giving rise to the survival of these butterflies overtime. Butterflies that had it are likely to be highly favored for survival against predatory birds, while those butterflies without this allele are likely to be heavily preyed upon by birds.
To find your altitude above sea level, you would use an altimeter to find the altitude.
Part 1:
A solution that causes a cell to swell is a hypotonic solution.
In an isotonic solution, there is no change in the size of the cell.
All three cause osmosis.
A solution that causes a cell to shrink is a hypertonic solution.
Part 2:
1. H. Energy
2.D. Endocytosis
3.G. Diffusion
4.B. Exocytosis
5.E. Facilitated Diffusion
6.A. Osmosis
7.C. Active Transport
8.F. Passive Transport
Sorry. I don't know how to explain part 3 ,but I tried and failed so I deleted it. Part 1 and 2 are correct though.
The phylum Arthropoda contains a wide diversity of animals with hard exoskeletons and jointed appendages. Many familiar species belong to the phylum Arthropoda—insects, spiders, scorpions, centipedes, and millipedes on land; crabs, crayfish, shrimp, lobsters, and barnacles in water (Fig. 3.72).
