Answer:
Species are adapted to their environments. By understanding the interactions within an ecosystem, scientists can develop an understand of how populations evolve (develop gradually) in response to their environment.
Answer:
a. Let us consider that L is responsible for late and l is responsible for early. From the mentioned data, it can be concluded that allele L or late is dominant over early. By crossing plants 1 and 4 we get the expected ratio of 3: 1, which shows that it follows Mendel's law of dominant.
b. The genotype of all the four plants are:
1st plant = Ll
2nd plant = ll
3rd plant = LL
4th plant = Ll
c. If the plant 1 is self-fertilized then the expected progeny will be 3 (late): 1 (early).
In case if the 2nd plant is self-fertilized, the expected progeny will be only early.
In case if the 3rd plant is self-fertilized, the expected progeny will be only late.
In case if the 4th plant is self-fertilized, the expected progeny will be 3 (late): 1 (early).
Phase change is the change in state. i.e. water to steam or ice to water
