The marrow cavity is also known as the medullary cavity. It is the central cavity of bone shafts where adipose tissue is stored. It is lined with a thin, vascular membrane called endosteum.

A team of researchers at IBM has created the world’s smallest magnet using a single atom which can store one bit of data on it.

The left atrium is the upper left chamber of the heart that receives blood from the pulmonary veins.

The heart is responsible for circulating blood throughout the body. The heart is divided into four chambers. The upper chamber is known as the atrium while the lower chamber is referred to as the ventricle.

S8 is an elemental form of sufur. In elemental form it can't be reduced or oxidized. Hence, it oxidation number is zero and thus sulfur is zerovalent here.

Natural Gas is a Non Renewable Resource of Energy because that does not renew itself once used, unlike the other choices. 

It is a resource that will not be naturally replenished.

The troposphere is the lowest layer of the atmosphere and where most clouds are. That means all weather is in the troposphere. Almost all weather occurs in the Troposphere, basically, the lowest layer that goes up to about 10 - 15 kms.

Complementary angles are those whose sum is 90.

Given here, is a right angled triangle, where anfle C is 90 deg. In this, sum of Angles A + C = 90, since, sum of angles in a right angled triangle = 180, angle C = 90 and

hence sum of A + B = 180 - C = 180 - 90 = 90.

Hence, the pair of cimplementary angles in the given triangle = Angle A + B.
