A team led by evolutionary biologist Hopi Hoekstra set out to test the hypothesis that predators are an agent of natural selecti
on on mouse color. They made 250 plasticine models of mice that were alike in every way except that half were painted white and half were painted brown. Complete a paragraph about two advantages and one disadvantage of using model mice instead of real mice in this experiment.
One advantage of models is that all the mice are exactly alike except for color, enabling the control of all variables except the one being studied. Models are also easier to work with than live mice. One disadvantage of using models is that they do not have the same smell and behaviors as real mice.
Another advantage is that models can be reused for the experiment for a longer period of time with less maintenance.
Methane gas is a great contributor to the global warming. It effects the green house of the earth and ozone layer is deteriorated. Grand father mountains are located in the North Carolina where the Methane gas pollution destroys the trees.
Meanwhile, your bones are busy making new blood cells. Working together, these systems maintain internal stability and balance, otherwise known as homeostasis. Disease in one body system can disrupt homeostasis and cause trouble in other body systems.
<u>Option-(B):</u> The following is not an observation or inference on which natural selection is based is the characteristics of a poorly adapted individuals which can never produce offspring.
Explanation:
The idea of natural selection basically follows the analyses of the heritable characters which passes from one generation into another, having the specific set of data or genome been transferred into there descendants. And how each specie goes through the process of survival in order to have more chances to acquire the required natural resources and shelter for them selves inside a region or area.
