Answer:
Due to early flowering in the mustard plant.
Explanation:
The scientists discovered that the flowering time of the field mustard had changed by observing more mustard plants which produces earlier flowers. The behaviour of the mustard plant change due to the change that occur in the environmental conditions that leads to early flowering in mustard plant. If this early flowering occurs for more generation, then the mustard plant will adopt this type of behaviour in normal environmental conditions that experience by the mustard plant.
<span>The answer should be: D) water supply
</span>Water is a perishable resource and its supply will limit how much population that an area could hold. <span>With a bigger population, the competition for water will be higher which make water shortage more likely. Others density-dependent limiting factor than competition would be disease, parasitism, and predation.

Answer: Ecosystem
Explanation: An ecosystem consists of all the biotic and abiotic factors in an area and their interactions. A niche refers to the role of a species in its ecosystem. A habitat is the physical environment in which a species lives and to which it is adapted.
The recombinat types are AB, and ab.
Genetic recombination involves the production of offspring with combinations of traits that differ from those found in either parent. In our case the parents are Ab and aB, which is not the same as the offsprings (AB,ab). During meiosis in eukaryotes, recombination involves the pairing of the homologous chromosomes a process.
