You are examining the impact of fish predators in a Trinidad stream on the life history traits of a newly discovered species, the puppy guppy. Compared with streams containing no predators, you discover that in streams with predators, mature male puppy guppies are smaller, puppy guppy offspring make up a lower percentage of gravid female mass, the average number of offspring produced by females increases, and the average weight of each embryo decreases. Which of the following responses in life history traits is the OPPOSITE of what you would predict based on the responses of Trinidadian guppies to predators? Group of answer choices mature male size number of offspring produced Percent of gravid female mass for which offspring account embryo weight

Scientific Notation

We have to deal with quantities that are extremely large or very small. For example- I may have 6,500,000,000 red blood cells, or the diameter of an iron atom is 0.000000011 inches. Numbers with many zeros can be inexpedient to work with, so scientists use scientific notation. It represents very large numbers or very small numbers in a simple form. We know that whole numbers can be extended to infinity, but we cannot write such large numbers on paper. Numbers that present in millions of places after the decimal point need to be represented simply. Thus, it is difficult to represent a few numbers in their extended form. Therefore, we use scientific notation.
