Adding large amounts of salt into your body causes your cells to become hypoglycemic (net movement into the cell outweighs net movement out) and causes the cells to boost. Via negative feedback loops, your body feels thirsty to dilute the salt in your cells to return them back to normal concentrations.
Halons and cfc’s both destroy ozone layer in the stratosphere.
- Chemicals with carbon, chlorine, and fluorine atoms are known as chlorofluorocarbons (CFCs), and they are neither poisonous nor combustible.
- They are employed as solvents, refrigerants, blowing agents for foams and packaging materials, and in the production of aerosol sprays.
- Halons, hydrochlorofluorocarbons, and chlorofluorocarbons all damage the ozone layer, which protects the planet from damaging ultraviolet (UV-B) rays from the sun.
- Additionally warming the earth's lower atmosphere, CFCs and HCFCs alter the climate on a global scale.
- Life on earth is made possible by the stratospheric ozone layer, which protects the planet from the sun's harmful ultraviolet (UV-B) rays.
- Ozone in the upper atmosphere is destroyed by man-made substances such halons, hydrofluorocarbons, and chlorofluorocarbons (CFCs)

Correct answer: A) Extension
Extension is a physical position that occurs when angle between the bones and the limbs of joint increases.
It takes place when there is a contraction of muscles and bones move the joint from a bent to a straight position, it is opposite of flexion, in which the angle between the bones and the limb at the joint decreases.
Example: During straightening of the leg, the angle between the tibia and femur increases, which shows extension has taken place.
Answer:
Option B. The force would be quartered (factor of 1/4).
Explanation:
The gravitational force between two objects can be expressed with the equation:
By analyzing the equation, we can see that if we multiply both m1 and m2 by 1/2, the resulting new F would be lower by a factor of 1/4 (as 1/2 times 1/2 equals 1/4).
Thus the correct answer is option B.
Nucleotides
Nucleotide consists of 5 carbon sugar, a nitrogen base and a phosphate
