Loam is a mixture of sand, silt, clay and humus. It is considered to be the best topsoil for growing plants because it has the right water-holding capacity for plant growth. It ALSO has adequate spaces between the SOIL particles to trap air REQUIRED by the roots of plants.

ong>Answer:

As trees grow, they help stop climate change by removing carbon dioxide from the AIR, storing carbon in the trees and soil, and RELEASING oxygen into the atmosphere. Trees provide many benefits to us, every day.

Why does planting trees help climate change?

Trees absorb carbon dioxide (CO2) during photosynthesis, in which they use SUNLIGHT to convert that CO2 into the sugars and energy they need to grow. ... Planting trees COULD therefore help mitigate climate breakdown, SINCE they absorb CO2 as they grow, and the carbon remains stored until the wood decomposes or is burnt

Do trees help with global warming?

As trees grow, they help stop climate change by removing carbon dioxide from the air, storing carbon in the trees and soil, and releasing oxygen into the atmosphere

Soil pollution increase the salinity of the soil making it UNFIT for vegetation, thus making it useless and barren. If some crops manage to grow under these conditions, they would be poisonous enough to cause SERIOUS health problems in people consuming them.

i) Cell wall

Plastids

Chloroplast

ii)Mitochondria is known as the power house of the cell because it provides ATP .

Explanation:

i)Animal cells each have a centrosome and lysosomes, whereas PLANT cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

ii)Mitochondria are known as the “powerhouse of the cell.” The ORGANELLE is responsible for the production of energy in a cell is mitochondria. This is the most vital part of the cell as it takes the food and makes energy for the other parts of the cell.

difference between weather and climate

Weather is the condition of the atmosphere at a particular place over a short period of time, whereas climate refers to the weather pattern, using statistical data, of a place over a long enough period to YIELD meaningful averages. Climatology studies CLIMATIC change.

similarities between weather and climate

Whereas weather refers to short-term changes in the atmosphere, climate describes what the weather is like over a long period of time in a specific area. Different regions can have different climates. Weather tells you what to wear each day.

ong>Answer:

AnswerBalancing chemical equation refers to balancing the stoichiometric COEFFICIENTS on the reactants and products side. This must be done as the chemical equation obeys the law of conservation of mass and momentum.

Hydrogen sulphide gas burns in air to give water and sulphur dioxide can be expressed in TERMS of equation as

H2S(g) + O2(g)→H2O(l) + SO2(g)

Steps to balance chemical equation

Following are the easy steps to balance the equation:

Step 1: Write the Unbalanced Chemical Equation

Let US consider the given REACTION. That is the reaction between Hydrogen sulphide gas burns in air to give water and sulphur dioxide.

H2S + 02 → SO2 + H2O

Step 2: Write Down Number of Atoms

Write down the number of atoms of each element present on both reactant and product side

Atom Reactant side Product side

H 1 2

S 1 1

O 2 3

Step 3: Add Coefficients To Balance the Mass in a Chemical Equation

Note that the coefficients that are to be added must be a whole number and ONE coefficient added applies to all the atoms present in that one particular molecule.
