What is the most important role that water plays for living organisms

-well, we all need water as living organisms in order to live. water helps us clean our body (just like you clean yourself in a shower to clean your skin),but drinking water helps you to take a shower inside your body! (sounds weird but true XD) you get the point... here are a few things water does to our body:

- water helps helps our skin to look beautiful (you can say youthful skin) and even beauty itself.

- it trashes body waste and toxins (like i said above)

- it gives us nutrients and minerals

- it helps us to maintain out blood pressure

- it also helps to regulate our body temperature

- it transfers oxygen through the whole body

- it helps with digestion

-  weigh loss

- gives you energy ( thats why when your exercising you need to drink water every 15 min XD)

-prevents from you have a stinky breath *-*

- it helps with back-pain, headaches, heart health...etc

- it helps boost your immune system

- increases your brain power

so those are what i got for you about why water is important to us  :D

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
