"How Does the Nervous System Maintain Homeostasis."

 

Our brain is like a thermostat, It regulates by detecting if we have the right amount of hormones, temperature, etc. When it is too low or high, the homeostasis comes in. When we are feeling hot: the brain senses it and activates sweat glands and dilates blood vessels; thus, maintaining our body temperature. When we are cold: the brain senses it and makes us shiver and constrict blood vessels; thus, maintaining body temperature. When it comes to hormones. When we have a little amount of hormones: the brain powers our endocrine glands to secrete more hormones. When it becomes too high, it shutdowns temporarily and powers it on when we only have a little amount of hormones. This is called a negative feedback loop. So basically homeostasis regulates our body to function normally. :)

Introduce The Term Atmosphere.

Introduce the term atmosphere.   Answer: The atmosphere is composed of a mixture of gases, solids and liquids. The atmosphere is made up of a mixture of atoms and molecules of different kinds. Contains mostly nitrogen, oxygen, carbon dioxide. These gases are constantly added and removed. The atmosphere is divided into five different layers because the atmosphere is not uniform therefore its properties change with altitude. It holds the oxygen we need to breathe. The Earth's atmosphere performs some optical tricks: The blue color of the sky. The white color of the clouds. The red sunrises/sunsets. The yellow sun. Aurora's Code 11.22.1.3.

A Function F Is Given By F(4x-1) = 4x2+5. Evaluate F(15).

A function f is given by f(4x-1) = 4x2+5. Evaluate f(15).   Answer:905 would be the answer if the function were defined as f(x) = 4x^2+5: Step-by-step explanation: But the function is defined as f(4x-1) = 4x^2+5. To evaluate f(15), you need to determine the value of x that makes 4x-1 equal to 15. 4x-1 = 15 4x = 16 x = 4 THAT is the value you need to substitute into the expression 4x^2+5 to get the answer.

Who were the two scientists who proposed the theory of seafloor spreading in the early 1960s? a. Charles Darwin and James Hutton b. Harry Hess and Robert Dietz c. John Butler and Arthur Smite d. f. Vine and d. Mathews   Answer: The correct answer is letter b. Harry Hess and Robert Dietz. Explanation: The two two scientists who proposed the theory of seafloor spreading in the early 1960s are Harry Hess and Robert Dietz. Harry Hess found out how oceanic mountain ranges, called oceanic ridges are essential to the tectonic movement that results in the drift of continents. Seafloor Spreading is the process that occurs at mid-ocean ridges wherein new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. According to this theory, the ocean floor is about a few hundred million years old, making it significantly younger than the continent. This supports the idea that molten rocks takes a long time to come out of volcanic-ally active oc
