Plants
because the cell in plant leaves has pigment that absorbs all light spectrum except for green light, so to our eyes it appears green.
If we boil ice it becomes water, this process is called?
melting
it stores genetic information
What is an example good conductor?
What is an example of good insulator?
Metal, Rubber
If we don't drink water for two weeks we might?
What does plant need to survive other than Carbon Dioxide?
Water & Sunlight
True or False
melting and vaporisation are endothermic processes in that they absorb or require energy
True
4 nitrogenous bases of DNA are
Guanine
Thymine
Cytosine
Atoms are made out of
Protons, Neutron, Electron
(which animal will survive no matter how high it falls)
squirrel
The process of making sugar using sunlight is called
Photosynthesis
Water freezes faster when the pressure is low
False
DNA stands for
deoxyribose nucleic acid
Electricity is?
flow of electrons
4 types of volcano is?

b. Sword volcanoes, Lava volcanoes, Moutain Volcanoes, Big Volcanoes
C. shield volcanoes, Lava domes, Mountain cones, Moutain dome
A. Shield Volcanoes, Composite Volcanoes, Lava domes , Cinder Cones
What is the correct plant life cycle?
a) seed - fruit - sprout - sapling - tree - flower - seedling
b) seed - germination - sprout - seedling&sapling - flower - fruit
c)seedling - germination sprout - seed&sapling - flower - fruit
d) germination - seedling - sprout - seed - fruit - flower - sapling
B) seed - germination - sprout - seedling&sapling - flower - fruit
How does sweating makes us cool?
when sweat vaporizes it absorbs heat from its environment and therefore it lowers our body temperature.
3 parts that makes DNA is
5 carbon sugar (deoxyribose)
phosphate group
Nitrogenous base
Electrolyte is?
A thing that turns into ions in solution(water) and has the ability to conduct electricity
Why are there seasons on Earth?
because the earth is tilted
Energy is what every living things want, the first step of photosynthesis makes energy, but plants uses extra energy to turn that energy in the sugar. Why does plant do this if they already created energy in the first place?
What is the definition of Solid, Liquid and Gas
1.solid - Matter that has a fixed shape and volume
2.liquid - Matter that has fixed volume but does not have fixed shape
3.Gas - Matter that has no fixed shape and no fixed volume
In DNA A can only pair with T and G can only pair with C. Why?
hint A G are purines (double ring shaped)
and C T are pyrimidines (single ring shaped)
if purine pairs with purine there won't be enough space and if pyrimidines with pyrimidines there are too much space
How did we turn the light bulb on with lemon?
lemon is electrolyte, when we put Zinc on to it zinc ionizes and it's electron travel to copper through the wire, this flow of electron makes electricity, using this electricity we were able to turn the light bulb on.
Why does Salt melts in water?
hint : salt is Na+Cl-
water is H20
H20 is partially positive and partially negative
the positive part of H20 sticks to Cl and the negative part sticks to Na and the water pulls the NaCl apart, thus melting the team
