Invasive species can be a big problem economically and environmentally. This simple food chain illustrates some of the feeding relationships in a (hypothetical) coastal ar Florida that has been heavily impacted by invasive green algae. One of your colleagues has the idea that introducing a new top predator (a big fish from China that will ea
Tish) into the area could help to control the invasive green algae. His idea is that the new big fish will eat the small fish, resulting in fewer small crustaceans being eaten, so
there will be more of the crustaceans to eat the invasive algae. Explain the potential problems of your colleagues' plan, including at least two supporting details.
Algae small crustaceans → small fish → (Your introduced fish would go here)

The use of logic making empirical observations and performing dissections were all part of the scientific studies by

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
