Blood behaves as a non-Newtonian fluid. As such, the viscosity of blood varies with shear rate. Blood becomes less viscous at high shear rates like those experienced in peak-systole.

• Ginkgo is a living fossil related to modern ginkgo dating back to 270 million years.
• It is the only living species in the division Ginkgophyta, all others being extinct.
• It is used in traditional medicines.
• These are large trees, normally reaching a height of 20–35 m.

Vitamin K is similar to fat-soluble vitamins the human body needs for complete synthesis of certain proteins that are required for blood coagulation and also certain proteins that the body uses to control binding of calcium in bone and other tissues.

Poliois a contagious viral illness that in its most severe form causes paralysis, difficulty breathing and sometimes death.

• Cell theory is a scientific theory which describes the properties of cells. These cells are the basic unit of structure in all organisms and also the basic unit of reproduction. 
• Viruses are not true cells. They lack the most important parts of the cell. Hence, the cell theory is not applicable to viruses.

Two pollutant emitted by motor vehicle react to form ground level ozone or smog which can cause respiratory problems and reduce visibility.

Environmental conditions are the main factor which determines balance of nature. The balance of nature is a theory that proposes that ecological systems are usually in a stable equilibrium (homeostasis), which is to say that a small change in some particular parameter (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system. It may apply where populations depend on each other, for example in predator/prey systems, or relationships between herbivores and their food source. It is also sometimes applied to the relationship between the Earth's ecosystem, the composition of the atmosphere, and the world's weather.

Plants produce CO₂ all the time as a metabolic product of respiration, but when light is available, they can use and fix some of this CO₂ as a substrate in photosynthesis.

• Endosperm is a tissue produced inside the seeds of most of the flowering plants around the time of fertilization.


• The endosperm of coconut contains a large quantity of clear liquid which is called "coconut milk" or coconut water.


• Scientific Name of coconut is Cocos nucifera.


 

Plants absorb nutrients and water through their roots. Plants need to get fluids and nutrients from the ground up through their stems to their parts that are above ground level.
