Question: What is phylogenetics? Phylogenetics is the study of the evolutionary relationship between different species or taxa, genes or protein sequences. It involves reconstructing evolutionary histories from the sequence information available by using different models. It helps usto determine the evolutionar relationship, to understand the process of evolution by the rate of change of sequences of gene or protein, mutation rates , divergence time and history etc. tapsinvolved in this are- sidentify models/parameters--- sequence collection from samples or database---sequence alignment---ffinding orthologues genes/ sequences---estimation of error using statistical parameters

Plant Physiology:

Greenhouse producers often supplement the atmospheres in their facilities with extra CO2. This addition increases plant growth, leading to more rapid plant production for sale. Describe (1) how this supplemental CO2 benefits growth and the physiological and biochemical level and (2) what drawbacks the plant might face upon transplanting to a homeowner’s garden.
