Characteristics of water
how do bugs use surface tension?
to walk on water
What is the end of the organ system(from what we went over)
biosphere
what is Polarity?
the difference in electronegativity between two elements in a molecule
what is adhesion?
water sticks to other things(h20 sticks to non h20)
why do humans need solvents?
To brake up food to digest it
What is the start of the organ system(from what we went over)
cell
Why is water less dense as a solid and more dense as a liquid?
The orientation of hydrogen bonds making molecules push farther apart
what is water solvent?
water molecules can be attracted to other molecules like salt and break up the existing bond
why do humans need capillarity action
movement of water in and out of your cellular structure that deposits vitamins, nutrients, and vital blood plasma.
What is an Ecosystem?
a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together
What is capillary action?
A action where the surfaces of a container is more polar than the water is to itself, leading to the water being higher on the sides.
what is Surface tension?
molecules bond on the surface of water because they are pulled down and to the sides
Are plants alive?
yes
what is the difference in populations and communities
A population is a group of the same species living in the same area. A community is a group of different species living in the same area.
What is specific heat?
the amount of heat needed to raise a temperature
What are the 7 properties of water?
specific heat
polarity
adhesion
cohesion
a lower density as a solid
capillarity action
solovents
is all of nature alive?
no
what is organization of life?
The biological levels of organization of living things arranged from the simplest to most complex
What is water cohesion?
water sticking to itself(h2O bonds to h2O via hydrogen bonds)
What is waters specific heat?
4,184 Joules
