Polar<span> molecules
water molecules have a weak, partial negative charge at one region of the molecule (the oxygen atom in water) and a partial positive charge elsewhere (the </span>hydrogen<span> atoms in water).The force of attraction is called a </span>hydrogen bond<span>.</span>
The biosphere is everything. the whole planet. so all of the above is right
Answer:
1. coevolution
2. abiogenesis
3. Endosymbiont Theory
4. It's estimated that over 99 percent of the species that have existed on Earth at some point in time are extinct today.
5. Coevolution implies that the evolution of one species is dependent on and works in relation to the evolution of another species. This may cause positive or negative impacts and could be beneficial to both organisms or only to one.
6. This theory states that the first building block of life that allowed for reproduction of organisms was the development of self-replicating RNA. This hasn't been able to be fully demonstrated in any science experiment but is based on the idea that there are RNAs that can catalyze biochemical reactions on their own without proteins.
7. This process points to the development of structures through the envelopment of smaller cells that perform specific functions. This is how eukaryotic cells evolved from prokaryotic cells.
8. This experiment was important because it showed that, in the right primordial soup, organic compounds could develop from inorganic compounds.

The type of competition that exist between the two species is INTERSPECIFIC COMPETITION.
There are basically two types of competition in any given ecosystem, these are intraspecific and interspecific competition. Intraspecific competition occurs among organisms of the same species while interspecific competition occurs among organisms of different species.<span />
