Answer:
A)The atoms form a bond with a bond length of 75 pm
Explanation:
The Morse curve is a plot of potential energy against internuclear distance between two atoms.
When two atoms are far apart, the bond energy is zero, this means that there is no significant interaction between the both atoms. Hence, when two atoms are positioned at infinite distance from each other, they do not interact with each other appreciably. At internuclear distance within the range of atomic diameter, attractive forces predominate between atoms. At shorter distances repulsive forces predominate and the energy of system is quite high. The minimum point in the plot of a Morse curve represents equilibrium between attractive and repulsive forces.
The internuclear distance that corresponds to this minimum point is known as the equilibrium bond length.
For the plot shown in the question, the minimum point occurs at an internuclear distance of 75pm. This corresponds to the bond length of the system.
<h2>B) is the correct option </h2>
Explanation:
In the given hypothetical condition roosting areas in buildings of any height are the fundamental niche of both bat species
- Niche is the role played by an organism that how they can live in an environment including their diet and shelter
- Fundamental niche represents all the environmental conditions where a species is able to live or can live
- There is no ecological barriers in case of this type of niche
- Since both bat species 1 and 2 can roost in buildings of any height this means there is no ecological barrier and heights of building represent all the conditions where bat species can live so it clearly represents fundamental niche
Living organisms obtain many of their requirements by diffusion. They also get rid of many of waste materials in this way. For example, Plants need carbon dioxide for photosynthesis. This diffuses from the air into the leaves through the stomata. It does this because there is a lower concentration of carbon dioxide inside the leaf as the cells are using it up. Outside the leaf in the air, there is a higher concentration. Carbon dioxide molecules therefore diffuse into the leaf down this concentration gradient :)
