When atoms in a covalent bond share electrons unequally (one atoms pulls more than the other), the bond is said to be a polar bond is formed when electrons are unequally shared between two atoms. Polar covalent bonding occurs because one atom has a stronger affinity for electrons than the other (yet not enough to pull the electrons away completely and form an ion).
Answer:
Camouflage and other visual illusions
Explanation:
There are several theories for why zebras have evolved to have striped coats. One of the lines of thinking is that it allows them to blend into long grass to avoid predation. The stripes blend into a sort of gray colour at a distance, making them difficult to spot.
The stripes may also "dazzle" their predators, because the properties of black and white stripes can give the illusion of movement. If there are many zebra huddled together, some moving, some not, it may be difficult for a predator to lock on to its prey.
It could be some sort of deterrent to stop bugs and other pests, because they can less successfully land on striped patterns.
I know that alcohol/ethanol is used as a growth stimulant and can be used in metabolism, thats one reason why the organism keeps pyruvate.
Answer:
Prions causes abnormal folding of the prion proteins in the brain.
Explanation:
Prions are the abnormal infectious agents composed only of the proteins and no nucleic acids. The prions cause several neurodegenerative diseases in the humans as well as the mammals.
The prions cause the cow mad disease in the cows by affecting the brain of the cow as the prions act on the prion proteins present in the brain only and change their conformation. This leads to the degeneration of the neurons and causes tiny pores in the brain giving sponge-like appearance.
This slows down the mental activity and thus ultimately leads to the death of the cow.
