The results of the phenotype do not make any sense in relation to the main aim of the experiment.
Smooth, wrinkled, yellow, green describe attributes relating to seed texture and flower colours in a result that simulates that of a plant breeding experiment, rather than a plant physiology experiment.
The determination of the effects of carbon dioxide deficiency in the soil on the phenotypes of peas is a physiological experiment. Hence, a result in the form of a plant breeding experiment would make not be relevant.
If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.
The body temperature of the mammal will be higher than that of the reptile. this is because the mammal body temperature does not depend on its environmental temperature while a reptile does not have a stable body temperature and depend on the temperature of its environment.
