Answer: negatively; electron.
In a chemical bond, proton and neutron didn't take action since they are located in the middle(nucleus) of the atom. The electron which on the outer side of an atom can interact with another electron from an other atom/molecule. Electron has negative charge, while proton is positive and neutron is neutral.
Answer:
If two similar looking species are able to produce fertile and viable offspring, then they belong to the same species.
Explanation:
According to the biological species concept , organisms are said to be of same species if they are able to interbreed and produce fertile and viable offspring.
In case if two species are closely related on the basis of external features, then they must be allowed to mate. The offspring produced in the first generation mating must be allowed to mate again. If in the second generation offspring are produced, then it shall prove that the two similar looking organisms are able to produce viable and fertile offspring thereby establishing the fact that they belong to same species.
Answer and Explanation:
<u>Available data</u>:
- S allele expresses sharp spines, and it is dominant
- s allele expresses dull spines, and it is recessive
- N allele expresses the presence of spines, and it is dominant
- n allele expresses the absence of the spines, and it is recessive

Answer:
The biosphere distributes water through the hydrological cycle that results from evaporation and perspiration.
Explanation:
The biosphere is the entire known ecosystem, which is formed by all organisms and living beings on the planet. The biosphere is known as the place where life is born; it is characterized by its evolution.
In the biosphere, the distribution of water is through the hydrological cycle in which it has a circular development, where water only moves from one place to another, in the same state or different physical states.
The cycle begins with the water falling into the biosphere; it is absorbed by plants, who need it to perform photosynthesis; in the process, the water passes to a vapor state. It is elevated to the troposphere where it condenses in clouds and finally falls to the biosphere in solid-state, and the cycle is repeated.
When the water fall to the surface, it can remain in it in a liquid state in a larger body of water, such as a river or a lake, or be absorbed by a living being. Still, the process will always end in its evaporation, condensation, and fall.
