Research a type of plant tropism not presented in the lessons. Create a meme below that name and describes the tropism.
In an ecosystem, plant tropism represented is phototropism which is towards the direction of light.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

2 H2 + O2 = 2H2O You have 20 grams of H, what's the mass of water?
Answer:
2H2 + O2 —-> 2H2O
The mole ratio of H2 to H2O is 2 : 2 = 1:1
4 moles of H2 = 4 moles of H2O
Moles of H20 = 4mol
Molar mass of H2O = 18g/mol
Mass = moles X Molar mass
= 4mol x 18g/mol
= 72g
Mass of H2O is 72g

A gas has a volume of 22. 6L at 3. 6 atm. What is the pressure of the gas at 44. 3L
Answer:
1.837 atm
Explanation:
According to Boyle's Law:
[tex]V_{1} P_{1} = V_{2}P_{2}[/tex]
(22.6L) (3.6atm) = (44.3L) (x)
x = 81.36 /44.3
x = 1.837 atm
This is because Volume and Pressure are inversely proportional. If one increases the other has to decrease.
differentiate between condensation polymerization and addition polymerization
Explanation:
The difference between addition polymerization and condensation polymerization is that in addition polymerization the polymers are formed by the addition of monomers without any by-products whereas in condensation polymerization, the polymers are formed due to the condensation of more than one different monomers resulting in the formation of small molecules such as HCl, water, etc., as by-products.

If a cross country runner travels at a speed of 10 mph and he runs for 2 hours, 20miles he will have run at the end of the 2 hours.
What is distance?Distance is a description of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can be used to describe a length in physics or to an estimate based on other factors in common usage.
The phrase is widely used metaphorically to refer to a measurement of the degree of distinction between two similar items since spatial intelligence is a rich source of implicatures in human understanding.
distance = speed x time
distance = 10 x 2
distance = 20miles

The temperature of CI2 is changed from 836.06K to 625.06K.if it's new volume is 14.509L what was its original volume in liters
V1= 19.229L
Explanation:
V1/T1 = k
V1/836.06=14.509/625.06
V1/836.06= 0.023
V1 = 19.229L
The temperature of CI₂ is changed from 836.06K to 625.06K. If it's new volume is 14.509L then its original volume in liters was 19.4 L.
What is combined gas law?The combined gas law is the law of of gaseous state which is made by combination of Boyle's law, Charle's law, Avogadro's law and Gay Lussac's law.
It is a mathematical expression that relates Pressure, Volume and Temperature.
(P1 × V1)÷T1 = (P2 × V2)÷T2
We can also use the following relation-
PV = nRT
According to the question, Pressure is constant and we can write the formula as-
V1÷T1 = V2÷T2
T1 = 836.06 K
T2 = 625.06 K
V1 = ?
V2 = 14.509 L
V1 = 19.4 L
Therefore, The temperature of CI₂ is changed from 836.06K to 625.06K. If it's new volume is 14.509L then its original volume in liters was 19.4 L.
