Which of the following best describes homeostasis? a.) the state of maintaining a stable internal environment despite changing external conditions b.) the state of maintaining a stable internal environment due to electrical impulses c.) the state of maintaining a stable internal environment due to chemical signals d.)the state of maintaining a stable internal environment when the external conditions are constant

A.the state of maintaining a stable internal environment despite external changes

a.) the state of maintaining a stable internal environment despite changing external conditions.  

A homeostasis can be defined as a property of the living cells, tissues and even the entire organism body to maintain the internal conditions stable in terms of temperature and pressure irrespective of the changes that occur in the external environment. The homeostasis allows organism to survive in the drastic environmental conditions.

On the basis of the above description, a.) the state of maintaining a stable internal environment despite changing external conditions is the correct option.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.

the answer is c) an oak tree
