Physiologist
* Some physiologists study insects or worms, some study fish, some study man.
* address some of the most exciting and pivotal questions in modern biology.
* analyze body-organ function, both separately and as part of an integrated system.
* are biologists
* can study how organs of an organism work together to make things happen.
* distinguish between external and internal respiration.
* generally apply the black-box approach to living systems.
* get into the nitty gritty about how and why our muscles react to stress.
* label it as ground substance.
* measure heart rates, blood sugar levels, oxygen uptake, and ion concentrations.
* say that chilies are truly addictive, like nicotine or cocaine.
* study the life functions of plants and animals
  - structure and function of organ systems
+ Physiology
  * Physiologists can study how organs of an organism work together to make things happen. In human beings, for example, the digestion of food hormones and other chemicals are made by the stomach, liver, and pancreas. Muscle contraction happens because of chemical messages made by nerves of that muscle. By learning how the body functions normally, physiologists and physicians can better understand what happens when organs do not function normally. For example, an understanding of how the thyroid gland functions has helped in treating goitre. Studies of the circulatory system and the nervous system have helped physicians understand and treat such illnesses like heart disease, stroke, and high blood pressure.

Exercise physiologist
* are people who make it happen.
* develop exercise routines and educate patients referred by a physician.
* have for the most part been educators more than practitioners.
* say tnat healthy people willing to train can finish a race at any age.

Plant biologist
* Most plant biologists know plants.
* Some plant biologists maintain that the banana was one of the first crops to be domesticated by man.
* classify several different types of fleshy fruits.

Plant scientist
* Many plant scientists earn a master's or doctoral degree.
* Most plant scientists recognize kinds.
* Some plant scientists spend most of their time in fieldwork studying crop growth.
* Some plant scientists study habitats
  - marine habitats
  - use the parallel terms monocarpy and polycarpy
* use equipment found in laboratories, greenhouses, and farms.

Mycologist
* are biologists who study fungi
  - botanists
  - scientists who study fungi
* investigate how fungi produce cheeses, fermented drinks, breads and antibiotics.
* study fungi of interest to medical, agricultural and food industries.
* take notes on their collections and often make spore prints.
* work with fungi.

Population biologist
* build models of how evolutionary change occurs.
* study the properties of groups of organisms.

Sociobiologist
* Most sociobiologists are genetic determinists, though some are more subtle than others.
* believe that staring at women helps to maximize male reproductive opportunities.
* often conflate social and genetic evolution.
* predict that helping decreases with kinship distance.
* say it's all about reproduction.
* think that analogies between ants and people are somehow revealing.
