By studying the population over an extended period of time, scientists can discover the change in number of population and its growth.
Florida panther population is listed as endangered, but it is estimated that the number is recovering. The population had grown from about 25 adults in 1995 to roughly 100 in 2010. The updated estimates from the 2017. calculated the number between 120 – 230 panthers which is still not a sustainable population size.
The answer is <span>C) Bb x Bb
</span>
B - the allele for black and white coloration
b - the allele for brown and white coloration
There are in total 11 offspring (<span>8 black and white and 3 brown and white),
In a monohybrid cross when both parents are heterozygous (Bb), the phenotype ratio is 3:1. We have ratio 8:3.
The ideal ratio would be 9:3 because it is the same as 3:1.
Therefore, the parents Bb and Bb will have </span>8 black and white and 3 brown and white with the ration 8:3 ≈ 9:3 = 3:1
The place where an organism lives and that provides the things it needs to survive is its habitat.
Answer:
In the last 60 years, brown tree snakes have become the embodiment of the bad things that can happen when invasive species are introduced in places where they have few predators. Unchecked for many years, the snakes caused the extinction of nearly every native bird species on the Pacific island of Guam.
