The density of a human body can be calculated from its weight in air, wair, and its weight while submersed in water, ww. the density of a human body is proportional to:

The correct answer is : Wair ÷ (Wair-Ww)

Explanation:

The density of human body can be calculated by the density of the individual in the air (Wair) and density in submerged in water (Ww). The density of human body is proportional to the ratio of the mass upon volume.

The mass of an individual is easily find by the density in air and volume can be calculate by the density in air minus density in water.

So, the correct answer is : Wair/(Wair-Ww).

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1
