What is Life Span? - Class 12 Biology - Reproduction in Organisms

The period from birth to the natural death of an organism represents its life span. The lifespan of an organism is not necessarily correlated with its body size, it can vary from less than one day to more than 400 years. Irrespective of the long or short lifespan of an organism, death is a certain phenomenon, i.e. no individual is immortal, except for single-celled organisms like Amoeba.

DISORDERS OF THE CIRCULATORY SYSTEM

Biology - Human Health and Diseases

Following are the diseases that can affect the circulatory system:

⑴ Hypertension:

It is the most common disease affecting the heart and blood vessels. A blood pressure of 120/80 mmHg is considered normal. But the increase in blood pressure beyond 140 mmHg (systolic) and 90 mmHg (diastolic) is called high blood pressure (hypertension). A diet full of oily food is known to increase cholesterol levels, causing thickening of the arteries which results in high blood pressure. Tobacco smoking increases the heart rate, contracts blood vessels and raises blood pressure. High blood pressure can harm the heart, brain, kidneys and eyes.

Class 11 - Physics - Mechanical Properties of Solids and Fluids - Important Points to Remember

1. Elasticity: 

It is the property of a material by which it tries to regain its original configuration after the removal of the deforming force applied to it. Example of perfectly elastic solid, quartz, phosphor, bronze.

2. Plasticity:

It is the property of a body by virtue of which it does not regain its original shape and size even after the removal deforming force, is called plasticity.
