1. ___________ structures are similar adaptive structures found in species that evolved in similar environments but do not have the same origin.?
homologous
analogous
2. When you sprint to catch the bus, your breathing rate increases. With respect to blood O2 concentrations, this process represents:
positive feedback
feedback inhibition
negative feedback
3._____ structures are found in species that evolved in different environments but have an underlying similarity in pattern and logic because they are modifications of an original ancestral structure.
homologous
analogous
1. Analogous structures are similar adaptive structures found in species that evolved in similar environments but do not have the same origin. This is due to
2. This is a negative feedback process because when the blood oxygen level decreases it will stimulate the brain stem to increase the breathing rate.
3. Homologous structures are found in species that evolved in different environments but have an underlying similarity in pattern and logic because they are modifications of an original ancestral structure.
Thank you...:)

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
