<u>The structural differences between prokaryotes and eukaryotes:</u>
The main differences between the prokaryotes and eukaryotes are the presence of nucleus in the eukaryotic cells and its absence of nuleus in prokaryotes.
Also, prokaryotes are single-celled, so that a cell is a whole organism. On the other hand, eukaryotes are mostly multi cellular, and therefore more complex. More complex DNA is in the nucleus in eukaryotic cells, that allow them to carry out a wide range of functions. Prokaryotes, as a single cell, have the features of simple present.
answer: Noroviruses, unlike the Ebola virus, are extremely hardy, able to travel through the air and stay for days on surfaces where they can infect new people. "Noroviruses are perhaps the perfect human pathogen," one CDC scientist declared in a scientific review.
Some factories drain chemicals into the local water supply. Some factories also release smoke and chemicals into the air.
The dodo was placed in the kingdom Animalia because if fulfills all characteristics necessary to be defined as a member of that kingdom. This also means that it is a motile, multicellular, heterotroph with eukaryotic cells.
Answer:
D. A positive charge, because of a covalent bond with oxygen
Explanation:
A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.
