Physiology plays a very critical role in aiding acclimatization of the organisms to their environment and combat the ecological challenges. One such example can be understood by the fact that physiological adaptations of the renal system have played significant role in maintaining the water content of organisms depending upon their nature of medium. Depending upon the nature of ecology, i.e. aquatic/sea water, terrestrial, arboreal or mixed, there are different features of renal system which help in acclimatization.
The animals residing in aquatic systems have developed ammoniotelic renal system which excretes largely ammonia out of their body due to presence of large amount of water in the medium. Similarly, land animals, particularly those residing at dry places, are uricotelic in nature and excrete large amount of uric acids to conserve water in their body. Finally, animals residing in mixed temperature regions are ureotelic in nature and have moderate capacity to conserve water.
Thus, with these adaptive changes, it can be seen that physiology plays a very crucial part in maintaining homeostasis and adapting to the ecological challenges.

The transition of life on land presented many challenges for organisms that were originally living in aquatic habitats. List three ecological challenges and the adaptations that plants and animals each evolved separately for coping with life on land. The challenges may (but not necessarily overlap), but the corresponding adaptations must be specific to either plants or animals, not both. **PLEASE BE DESCRIPTIVE AND PROVIDE FULL SENTENCES**

Discuss what value means to customers and the role that price plays in value “value is low price” implies that “monetary price is the most important determinant of value to a customer with the company focusing on price” (Zeithaml, Bitner & Gremler, 2018, p. 463). Marketers must recognize how they interpret various prices and how much of a perceived sacrifice. Pricing approach when customers define value as low price include odd pricing, discounting, penetration pricing, and synchro-pricing. “value is everything...
Question 1: Homeostasis, Common Ancestry, and Divergence a) One problem that all respiring organisms share is the need for biological structures that allow efficient uptake of oxygen and removal of carbon dioxide. Two types of structures that have evolved for carrying out gas exchange are gills and lungs. The table below lists organisms according to the type of structure they use for gas exchange. Describe the general process of gas exchange that occurs between a gill or lung and the...
