ANSWER
A water molecule consists of one oxygen atom bonded to two hydrogen atoms by covalent bonds. Since oxygen is more electronegative as compared to hydrogen atoms, the shared electrons are attracted towards the oxygen atom. This imparts partial negative charge to the oxygen atom and partial positive charge to hydrogen atoms. The overall effect is making the water molecular a polar one. The presence of free hydrogen atoms makes water molecule to form hydrogen bonds with other water molecules and with other polar molecules.

<h2>Biodiversity hotpots</h2>
Explanation:
All of the given option can be the biodiversity hotspots EXCEPT:
Tundra biome.
Biodiversity is defined as the total number of species present within a biogeographic region.
A biodiversity hotspot is that geographic area where significant biodiversity exists.
A tropical biome, a mountain ecosystem and an island ecosystem can have a significant biodiversity depending on the climate and other environmental condition.
A tundra biome is totally covered with snow and have a very few areas of vegetation and could support only a few species So it cannot be a choice for Biodiversity hotspot.
Answer:
The ability to absorb other cells gave some prokaryotes a survival advantage.
Explanation:
Answer:
2, 4, and 5 refers to scientific revolution while on the other hand, the remaining statements shows scientific observation.
Explanation:
Cloning has the potential to significantly benefit a great many people, so it should not be considered immoral or risky is refers as scientific observation.
A scientist thinks that he might find serious inconsistencies in the fossil record if he conducts an excavation in a new location is refers scientific explanation because explanation is needed for it.
The rocks present in western Africa and eastern South America formed at the same place and at the same time is scientific observation because the scientists takes the data.
Even if modern organisms are found in ancient portions of the fossil record, this wouldn't challenge the theory of evolution in any way is refers to scientific explanation.
The cloning of organisms is an exciting area of study, and more resources should be be devoted to it so it is refers as scientific explanation.
The age, type, and composition of ancient rocks in western Africa are nearly identical to the age, type, and composition of rocks in eastern South America is scientific observation which is taken by the scientist through research.
