decomposers in the ocean

Let us learn about decomposers in the ocean

Depending on the depth & availability of temperature & sunlight, the ocean is divided into different zones & this offers the presence of different type of organisms & the decomposers in each zone.
Intertidal zone - Lots of crabs, sea urchins, seaweed & starfish tend to live here.
Neritic zone - sea weeds, Crustaceans & large number of fishes are found in this zone.
Pelagic zone - This includes the photic zone, & aphotic zone.
Photic zone - Strengthen phytoplankton due to the availability of whales which feed on this phytoplankton are found here & sunlight.
Aphotic zone - This is the dark zone The sun’s light does not reach & hence is the home for many decomposers which feed on bits & pieces of dead stuff that sink down to the bottom.


Decomposers in the Ocean consist of marine worms, bacteria, & Marine Seaweed. Marine seaweed help protect marine life. It's also important because all of these things help eat away the dead organisms

diagram of the heart


Let us learn to draw diagram of the heart

The heart includes 4 chambers & four valves. The inferior vena cava, superior vena cava, & pulmonary vein are the large veins that empty into the heart; the aorta & pulmonary artery are large arteries that lead out of the heart. The mitral valve & tricuspid valve allow blood to move from the left & right atria, respectively, to the left ventricles & right ventricles. The blood is then pumped out of the ventricles to lungs & the body

conditional probability calculator

Let us learn about conditional probability calculator

Conditional probability calculator is the branch of mathematics which deals with random events & chance. Conditional probability calculator is related to our common sense notion of chance but uses exact numbers.

The conditional probability calculator comes in handy if you want to know the odds of a specific outcome. Best for an example lets us say if you want to know the odds of rolling an even number with a die. If you look at the conditional probability calculator the first area, you should enter the number six because there are six sides or number on the die. The second area you would enter how many odd numbers there are on the die that is three. The same goes for rolling an even number, hence you would enter the number three in the third field. Once you finished entering in the required information click on calculate & it gives the probability of rolling not only the odds of rolling an even number but also the odds of rolling a & odd number.

factoring of polynomials


Let us learn about factoring of polynomials

Polynomial factorization defined as factoring a polynomial into irreducible polynomials over a given area. Factoring of polynomials is the inverse process of multiplying polynomials. After factoring of polynomial, if you divide the polynomial with the given factors then the remainder will be zero. Basically polynomial is referred as an algebraic expression that has at least 4 terms. You can express that polynomial as a multiple of 2 or more polynomial that has less than 4 terms.

factoring of polynomials Formulas

1: x 2 - y 2 = (x + y)(x - y)

2: x 2 + 2xy + y 2 = (x + y) 2

3: x 2 - 2xy + y 2 = (x - y) 2

4: x 3 + 3x 2y + 3xy 2 + y 3 = (x + y) 3

5: x 3 - 3x 2y + 3xy 2 - y 3 = (x - y) 3

The best example on factoring of polynomials:

3x3- 81 = 3(x3 - 27)

= 3(x3 - 33)

= 3(x - 3)(x2 + 3x + 9)

The best example on factoring of polynomials:

7x2 + 14xy + 7 = 7(x2 + 2xy + 1)

= 7(x + 1)2

Let us learn about Balancing chemical equations by using Balancing equations calculator.

Balancing equations calculator is the technique that gives balances same values on both the sides of a chemical equation i.e. on Right Hand Side (RHS) & Left Hand Side (LHS). Balancing equation acquire when you get the same value on both sides.


Write the chemical equation in words which shows the reactants a& the products of a chemical reaction. Write a chemical equation using symbols & formula. it may be remembered that molecules of the elements like hydrogen, fluorine, chlorine, nitrogen, oxygen, bromine, & iodine are diatomic & should be represented as such in chemical equation. H2, N2, O2, F2, Cl2, Br2 & I2. To balance a chemical equation, change the coefficients of molecules of the reactants or the products. The number of atoms in the compounds or molecules should remain the similar. Write an upward arrow beside the formula if the substance is a gas & downward arrow besides the formula if it is a precipitate. Or Specify with g for gaseous substance, one for liquid substance, s for solid substance, & aq for aqueous substance.

These are things to be followed while Balancing chemical equations:

dipole moment

Let us learn about dipole moment

The product of the magnitude of the charge & the distance of separation between the charges is said to be as Dipole moment. It is represented by the Greek letter 'm'. Mathematically it is equal to

Dipole moment (m) = charge (e) x distance of separation (d).

Dipole moment is expressed in the units of Debye & written as D

(1 Debye = 1 x 10-18e.s.u cm)

Dipole moment is a vector quantity & is represented by head pointing towards a negative centre & a small arrow with tail at the positive centre.

Calculate the ionic character of HCl. Its measured dipole moment is 3.436 x 10-30 coulomb meter. The HCl bond length is 2.29 x 10-10 meter.

Dipole moment corresponding to 100 % ionic character of HCl

= 1.602 x 10-19 C x 1.29 x 10-10 m

= 20.67 x 10-30 Cm

Actual dipole moment of HCl = 3.436 x 10-30 Cm
