Answer:
The labels that best complete the flow chart are:
X: Free nitrogen is in the atmosphere and Y: Producers captivate components of nitrogen via their roots.
Explanation:
Soil comprises nitrogen, it is taken up by the plants accompanied by other minerals in the process of taking water from the soil. The presence of nitrogen in the soil takes place by the process of decomposition of decaying and dead substances. The process of decomposition dissociates nitrogen and discharges it within the soil. This nitrogen is eventually taken up by the plants.
Label X shows that in the air presence of nitrogen takes place in its free state, as it is one of the gases found in abundance in the atmosphere of the Earth.
Answer:
Abstract American photographer Catherine Opie combines portraiture and documentary photography in her photographic series titled Domestic. At the center of this series lies the idea of community and the question of how community is constructed, a theme which unites Opie’s seemingly disparate bodies of work.

Abiotic natural capital comprises subsoil assets (e.g. fossil fuels, minerals, metals) and abiotic flows.
Biotic natural capital or ecosystem capital consists of ecosystems, which deliver a wide range of valuable services.

<u>Answer</u>: option B they have a random gene mutation that affects their fur colour.
<u>Explanation</u> :-
- <em>Variation</em> is the phenomena which occurs in all populations.
- These variations result in slight differences in the phenotypes of individuals .
- These variations only arise due to <em>random mutations </em>that arise in the individuals’ genome and then can be inherited by their offspring.
- There is always a probability of one particular trait to make the individuals survive better in the environment as compared to other trait.
- The individuals having the trait that helps them to survive better in the environment tend to survive more and leave more progeny. This is termed as <em>survival of the fittest</em>.
- Thus, according to the question it can be inferred that the dark fur colour arose due to a <em>random mutation </em>since it is the only source of variation. Since, in the given environmental conditions the mice having the dark fur colour were less susceptible to the predators they are better fitted to survive.
- The dark brown fur coat mice, survive better, leave more progeny and hence, increase their population with time. However, the orginal source of origin of this trait was a random mutation. Had this mutation not occured, the dark coloured fur mice would not have been there.
So, a <em>random gene mutation affecting the fur colour made the dark coloured mice first appear in the population.</em>
