Negative feedback is a mechanism in which function of a cell or an organ is decreased. It lessened the output of a system and maintain system function which is known as homeostasis. It is a regulatory mechanism of normal physiology. Some of examples are 
blood sugar level regulation, regulation of blood pressure, thermoregulation and many more.
 
        
             
        
        
        
- <u>Adaptations </u><u>are unique characteristics that allow animals to survive in their environment.</u>
- <u> There are </u><u>three </u><u>types of adaptations: </u><u>structural</u><u>, </u><u>physiological</u><u>, and </u><u>behavioral</u><u>. Structural adaptations are how the animal's body functions or looks on the ou</u>tside.
What are 3 ways animals can adapt to their environment?
Animals adapt to their environment in a variety of ways; an animal's color, behavior, defense or diet, for example, may serve adaptive functions.
- Color and Pattern Adaptations. 
- Behavioral Adaptations. 
- Defensive Adaptations. 
- Dietary Adaptations.
What is an example of an animal adapting to its environment?
- Adaptation can protect animals from predators or from harsh weather. 
- Many birds can hide in the tall grass and weeds and insects can change their colour to blend into the surroundings.
-  This makes it difficult for predators to seek them out for food.

<span>The event that a "the first male has had a kidney stone" and b "the second male has had a kidney stone" is true. Random selection is used by the medical researcher in selecting two males from the population. Since simple random sample is defined as a subset of a statistical population wherein each member has an equal probability of being chosen, even if the probability is only 8%, males a and b may really have had a kidney stone.  </span>
