What is a genetic change that occurs over generations in response to natural selection in a population
What is a phenotypic change that occurs in an individual in response to a short-term change in environmental conditions
What is a highly intergrated group of cells with the same structure and function
What are the four basic types of tissue
Connective, nervous, muscle, epithelial
Most muscle tissue is _______, which consists of the long cells called muscle fibers. controlled by the nervous system
striated muscle
________ makes up the walls of the heart. The cells branch and directly connect with each other. Some contract spontaneously
cardiac muscle
_______ cells are tapered at each end and form a tissue that lines the walls of the digestive tract and the walls of arteries.
smooth muscles
______ is made up of cells that are loosely arranged in a liquid, jellylike, or solid extracellular matrix
connective tissue
the ______ cover the outside of the body and line the surfaces of organs. These tissues consist of laters of tightly packed cells
epithelial tissues

cells are bathed in internal fluid called the ______
interstitial fluid
What is homeostasis that occurs by conformation to the external environment
conformational homeostasis
What requires a physiological mechanism that adjusts the internal state to keep it near a specific value or within limits that can be tolerated, reguardless of the external conditions
regulatory homeostasis
What is a structure that senses some aspect of the external or internal environment
a sensor
What is a component of the nervous system that evaluates the incoming sensory information and 'decides' if a response is necessary to achieve homeostasis
an integrator
what is any structure that helps to restore the desired internal condition
an effector
what occurs when the regulatory system makes a change in the opposite direction to a change in internal conditions
negative feedback
many animals can control their body temperature through what process?
_____ keep their body temperature constant
_______ experience changes in body temperatures
