Best Answer: producers use nutrients in the soil > consumers eat the producers, obtaining the energy and nutrients that the plant took > the consumer dies and is decomposed by a decomposer (usually decomposing bacteria), which replaces the nutrients back into the soil > producers use the nutrients in the soil.
now put that into your own words; if you cant, try drawing pictures to help you :) that might help you revise too, but remember to add info underneath, otherwise you might not understand it when you come back to it later
Answer:
The general formula for an acid is HnX where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
Explanation:
The general formula for an acid is HnX) where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
An example is H2SO4, also called sulfuric acid
It shows that H2SO4 has 2 hydrogen atoms, so in the formula HnX n=2
X fro H2SO4 is SO42-, it's a polyatomic ion. Since it has a negative charge of 2- it needs 2 hydrogen atoms to bind and form H2SO4
Answer:
High conductivity
Explanation:
Metals exhibit high conductivity due to the mobility of valence electrons.
Answer:
Inherited traits are passed from parent to offspring by information coded in
the DNA or Deoxyribonucleic Acid
Answer: The volume of the gold is 
The mass of gold is 19.3 g
The density of gold is 
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of gold = 19.3 grams
To calculate the volume of cube, we use the equation:
where,
V = volume of cube
a = edge of cube
Volume of gold = 
Putting values in above equation, we get:
Putting in the values we get:
Thus density of gold will be
