Answer:
Both are type of natural selection and ultimately lead to selection of a set of phenotype over the entire available genotype spectrum.
Explanation:
Both the stabilizing selection and directional selection are two forms of natural selection
Also in both the selection process, a new population with a better fitment to the prevailing environmental and physical conditions evolves.
In stabilizing selection, an average phenotype is selected over extreme variation. However, by this process of selection the genetic variance of the population will decrease.
However in directional selection, phenotypes at one end of the existing variation are selected over the entire spectrum
Answer:
An organism is able to produce sweat so that it cools off which helps it to cool down when exposed to high temperatures.
It's vessels are able to vasodilate and vasoconstrict to regulate temperature.
An organism stores fat as an insulator.
Eye pupils dilate and constrict to control the amount of light entering the eye.
If an organism touches a hot surface, nerve impulses are sent to the body to move and not get injured.
In a nutshell: an organism maintain a constant internal environment with homeostasis. And is able to respond to changes in the atmosphere by electrical impulses (nervous system) or the endocrine system by the release of chemicals (called hormones)
Pros - Gets a lot of sunlight
Cons - Might get dehydrated
Answer:
Angiosperms evolved during the late Cretaceous Period, about 125-100 million years ago.
hope it helps.
I’m pretty sure it’s A, it works like Electrical Wires
