It is here that the control center establishes a set point at which the variable is to be maintained. One a set point is determined‚ the control center is able to send information along the efferent pathway to the third mechanism; effector which responds to the stimulus instructed by the control center.

The endocrine system works with the nervous system to maintain homeostasis. The endocrine system secretes hormones in the human body‚ which are produced in endocrine glands and are released into the bloodstream to travel to the its specific target cell‚ tissue‚ or organ. Exocrine glands produce chemicals that are discharged into the surroundings. Hormones can either produce short-lived responses or long-term responses. An example of a short-lived response is when adrenaline (epinephrine)causes the

Over the course of a couple weeks‚ ten tests were performed. First‚ a gram stain was performed‚ indicating the bacterium was gram negative. An aerotolerance test determined that the bacterium was a facultative anaerobe. Next‚ a negative result in the

Exopolymeric substances are required for Calcium carbonate precipitation Abstract: Introduction: Different minerals precipitation by microbes is a common phenomenon‚ and carbonates are most common mineral formed. Many micro-organisms are having the ability in undergoing the process of mineralization‚ although different minerals have been precipitated by microbes which include carbonates‚ sulphates‚ silicates etc [1]. Amongst all these‚ carbonates are the most common minerals formed. Carbonate precipitation

Grajo I. INTRODUCTION Bioinformatics is the branch of biological science which deals with the study of methods for storing‚ retrieving and analyzing biological data‚ such as nucleic acid (DNA/RNA) and protein sequence‚ structure‚ function‚ pathways and genetic interactions. It is very important since it contains large amount of information regarding biomolecules that a human mind is not able to store and process such data. There are different data bases that can be used like National Center
