The only dry membrane it is the unique because of its waterproof nature (due to the keratinized layer) it is the body’s only dry membrane
Surface tension is caused by the attraction of the particles in the surface layer by the bulk of the liquid.
Answer:
disruptive selection
Explanation:
Disruptive selection is the natural selection that favors two extreme phenotypes but does not favor the intermediate phenotype. Here, the survival and reproductive success of two extreme phenotypes are higher than that of the intermediate phenotype due to their higher fitness value in the prevailing conditions. The presence of deeper voices in males and less deep voices in females due to high and low levels of testosterone respectively represents the disruptive selection as the phenotype present at two extreme ends are favored.
Answer: Tin(4+)
Explanation:
It is actually a monoatomic tetracation and an elemental tin.
Also a low-molecular-weight heparin with anticoagulant properties that is used in the prevention and treatment of VENOUS THROMBOEMBOLISM, and to prevent clotting during EXTRACORPOREAL CIRCULATION.
Atoms that are unstable undergo radioactive decay,
Elements with half life(that's how we know that it decayed),
Atoms that release energy and particles(like alpha beta and gamma particles) and,
Elements that have turned into a new element (as in radioactive decay no. of protons can decrease)
And to be precise the elements that have neutron to proton ratio of more than 1 undergo radioactive decay, since the nuclear attraction gets all weird after that.
