Answer:
Peacock with larger tails are most likely to produce more progeny.
Explanation:
Sexual selection is a type of natural selection wherein individuals with some specific genetic traits are preferred as a mate for interbreeding by the individuals of the opposite gender of the same species. For instance, in some species, males with large size have a greater chance to mate and pass on their genes to the progeny. This results in an increased frequency of the genes for the larger body size in population over time. Therefore, sexual selection results in the reproductive advantage for some individuals over others of the same species and sex.
In the given example, a peacock with larger tails is preferred as a mate by peahens and is able to produce more offspring. Due to its reproductive advantage, larger tails in peacocks are not selected against by natural selection.
The best approach for Tyler is a controlled experiment if he wants to directly observe the outcome.
A controlled experiment is designed to minimize the effects of the variables other than the independent variable. A controlled experiment allows reliable results because he can do the experiment specific to the problem and variables involved.
No, they don't have organs and organ system.
Cells form tissues, Tissues form organs, Organs forms organ system; Unicellular have their own one cell only. So, it can't possible that they have organs or organ system.
The first is plant
Second is animal
Third is fungi
False. hot rises and cold sinks.
think of the ocean, it is colder the deeper you go because the cold water sinks while the hot water rises. plus there's also the heat of the sun on top.
