Which of the following is an example of biomimicry that has been used to solve a real-world problem?

Dissecting polar bear feces to formulate a protocol for increasing the world's overall food supplies
Modeling the blades of wind turbines after humpback whale flukes to reduce drag and stalling
Studying the reproductive behaviors of crustaceans to better understand human reproduction
Using migration patterns of pelagic fish to create more realistic topographical maps of the oceans

Two male mice, which we will call male a and male b, are both phenotypically normal. male a was from a litter that contained half phenotypically normal mice and half dwarf mice. the mother of male a was known to be homozygous for the normal igf2 allele. male b was from a litter of eight mice that were all phenotypically normal. the parents of male b were a phenotypically normal male and a dwarf female. male a and male b were put into a cage with two female mice that we will call female a and female b. female a is a dwarf and female b is phenotypically normal. the parents of these two females were unknown, although it was known that they were from the same litter. the mice were allowed to mate with each other, and the following data were obtained: female a gave birth to three dwarf babies and four normal babies. female b gave birth to four normal babies and two dwarf babies. which male(s)mated with female a and female b? male a with both females male a with female b, and male b with female a male a with female a, and male b with female b could not be determined male b with both females

How does deforestation affect the water cycle? a. it increases the amount of runoff b.it increases the amount of percolation c. it increases the amount of transpiration d. it increases the amount of precipitationa it increases the amount of runoff

How is habitat fragmentation related to biodiversity loss? less carbon dioxide is absorbed by plants in fragmented habitats. in fragmented habitats, more soil erosion takes place. populations of organisms in fragments are smaller and, thus, more susceptible to extinction. animals are forced out of smaller habitat fragments. fragments generate silt that negatively affects sensitive river and stream organisms.
