This is called secondary active transport
Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
B. I think I'm not so sure but that's my best guess.
A) platelets aggregate at the wound site, and the fibrin mesh forms
Although the blood vessels do constrict, that's during homeostasis
Gravity Probe B showed this to be correct, in 1905 Einstein determined that all laws of physics are the same for all non accelerating observers <span />
