Khushi Bothra 7 years, 9 months ago

There's nothing called soil dispersal maybe it would be seed dispersal or soil erosion. Soil erosion is done when wind carries away the top layer of soil or water in an heavy pace washes away the top layer of soil. Seed dispersal is the process of dispersal of seed. Seed dispersal can happen through wind, water etc

Amar Kumar 7 years, 10 months ago

We breathe by expanding your chest wall and contracting your diaphragm. Your diaphragm is a big thin muscle that sits under your lungs and heart. The diaphragm pulls your lungs downwards and your chest wall pulls outwards and upwards – this causes your lungs to stretch and pull air inside. When you relax, the elasticity of the lungs pushes air out.

Breathing consists of two phases called inhalation and exhalation.

Inhalation:- In order for air to be drawn into the lungs during inhalation the volume of the thorax must increase. This is brought about due to the contraction of respiratory muscles. The diaphragm contracts and flattens and the intercostal muscles contract to pull the ribs up and out. The increased volume within the thoracic cavity lowers the pressure within the lungs with respect to the atmospheric pressure. Consequently, air is drawn into the lungs down a pressure gradient.

Exhalation:- Inhalation is now complete and the next step is exhalation. The diaphragm relaxes and moves up and the relaxation of the intercostal muscles moves the ribs in and down. This has the effect of decreasing the volume within the thoracic cavity and increasing the pressure within the lungs with respect to atmospheric pressure. As a result, air moves out of the lungs down a pressure gradient.

0Thank You

Amar Kumar 7 years, 10 months ago

A reversible chemical reaction is one that can go in both directions means reactants can turn into products, and products can turn back into reactants.

Examples of reversible reactions include the Haber process and the binding of oxygen to hemoglobin in the blood.

Other example is :- H₂CO₃ (l) + H₂O(l) ⇌ HCO⁻³(aq) + H₃O⁺(aq).
