1. How does nephron separate urine from blood ?

2. What properties of metals help to make them the following ? [ Mention two points for each ]
i. Utensils to cook in it
ii. Conducting wire
iii. Body of aeroplane

- Plagiarised / Random answers will be reported ! ​

1) Each of the nephrons contain a filter called the glomerulus (pronounced: gluh-MER-yuh-lus). The fluid that is filtered out from the blood then travels down a tiny tube-like structure called a tubule (pronounced: TOO-byool). The tubule adjusts the level of salts, water, and wastes that will leave the body in the urine.

2) i) properties of metal which makes it suitable for using it as utensils. it is good conductor of heat . It easily gets heated . It doesn't take a long time to get heated.

ii) The property which allow the metals to be drawn into wires is called ductility.

Conductivity: Metals allow heat and electricity to pass through them easily. Copper,silver,gold,aluminium,iron metals are good conductors of heat.

iii) Of primary concern in aircraft maintenance are such general properties of metals and their alloys as hardness, malleability, ductility, elasticity, toughness, density, brittleness, fusibility, conductivity contraction and expansion, and so forth.

the correct answer is:

a. formation of precipitation
