Answer:
The group that receives the treatment in an experiment (here, the watered pot) is called the experimental group, while the group that does not receive the treatment (here, the dry pot) is called the control group. The control group provides a baseline that lets us see if the treatment has an effect.
Explanation:
A phylogeny of the same taxa based only on morphological traits:
Some highly conserved genetic sequences can result in unrelated species appearing closely related in a molecular phylogeny, and not reflect the same pattern as the morphologic phylogeny.
Gene sequence changes may not result in morphological changes.
Gene sequences always provide more data than morphological traits.
Morphological analyses always provide more data because each morphological trait is the result of the expression of many genes.
The molecular data may be based on the analysis of introns, which aren't expressed and don't contribute to the evolutionary history of a group of taxa.
Why is molecular data more accurate?
Phylogenetic trees reconstructed from molecular sequences are often considered more reliable than those reconstructed from morphological characters, in part because convergent evolution, which confounds phylogenetic reconstruction, is believed to be rarer for molecular sequences than for morphologies

Answer:
The phenomenon in which osteoclast results in the degradation of the old bones and encourages the generation of novel bones by the assistance of osteoblasts is termed as bone remodeling. The remodeling of bones takes place throughout life, that is, whenever it is required. Some of the elements that monitor the process of bone remodeling are the concentration of serum vitamin D, serum level of calcium, and the level of calcitonin and growth hormone in the blood.
Thus, whenever the bone gets degrade or becomes useless it gets replaced by the process of bone remodeling. Hence, the hypothesis of 'use it' here signifies the usage of bones or else they will get useless or get degrade.
In the process of bone remodeling formation of more dense bones takes place due to the renewal of the destructed bones. This results in the presence of both the damaged bones and the newly formed bones at the same time, hence, it can be concluded that more bones are present at the time of bone remodeling.
