I think its batholith
It's formed when magma is forced upwards it then cools and solidifies
The correct answer is option C, the concentration of the hydroxide ion is greater than the concentration of the hydronium ion
Reason -
An acidic solution has an ability to contribute hydrogen ion. Here a hydronium ion (H3O+) has an extra H+ ion along with a water molecule. Thus presence of hydronium ion in larger amount than the hydroxide ion would make the solution acidic. Thus, the concentration of hydroxide ion should be less than the hydronium ion to make the solution a basic solution.
Answer:Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size.
Answer:
E. 3, 6, 7, 4, 5, 8, 1, 2
Explanation:
Systemic circulation is the circulatory pathway which is involved in the transport of the oxygenated blood to the body when pumped by the heart through arteries, capillaries and then back to the heart.
In the given question, the order of vessels in the systemic circulation has been asked which begins with the entry of the deoxygenated blood to the heart.
1. The deoxygenated blood enters the blood from vena cava to the right ventricle.
2. From the right ventricle, the blood enters the right atrium which pumps the de-oxygenated blood to the lungs through an artery called the pulmonary artery.
3. In the lungs, the blood becomes oxygen rich and is returned to the left atrium through the pulmonary vein.
4. The blood then enters the left atrium which is then pumped to the body through the main artery called the aorta.
This completes the systemic circulation and thus, Option-E is correct.
