A. The only difference in the shown diagram is the temperature.
In setup 1, the temperature is 20 degree and in the setup 2, the temperature is 15 degree.
So, the scientists must be studying the effect of temperature in this controlled experiment, where temperature is variable.
The habitat of the lily plant is tropical, which have a mean temperature of 18 degree Celsius. So, the scientist must be studying the effect of low temperature on lily.
The possible hypothesis could be, The lily could survive in slightly lower temperature, if proper amount of light and other nutrients are available.
B. The replication of the experiment is very important to see the validity of the result obtained, it also reduces the variability in result and avoid any preset ideas.

The homologous chromosomes have the same genes in common. Each cell has at least two sets of chromosomes which one comes from one’s father also called as paternal chromosome and mother, called as the maternal chromosomes. These chromosomes are what makes the child obtain the characters and may depend on the traits the parents possess. Homologous chromosomes are not duplicated chromosomes or identical however, they are analogous or similar. The alleles for a specific characteristics isn’t the same but the same genes are in the same order.
Final answer:
Pairs of homologous chromosomes, or homologs, share similar features, carry the same genes in the same order, differ in their parent origin and engage in genetic information exchange during meiosis.
Explanation:
Pairs of homologous chromosomes, called homologs, share several key features. Firstly, they are typically the same length and shape, and they carry the same genes in the same order, although the versions of these genes (called alleles) might vary. Secondly, each pair is derived from separate parents; one comes from the mother (maternal chromosome) and one from the father (paternal chromosome). During cell division, particularly during the phase of meiosis, these homologous pairs align with each other, allowing equivalent genetic information to be exchanged, a process known as crossing over.
