Answer:

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

Sucrose and lactose are disaccharides that have the same chemical formula, C12H22O11. However, these sugars have different chara

d1i1m1o1n [39]

The answer is Disaccharides are different in structure because they are not made up of the same monosaccharides, and this gives them different properties.

Both sucrose and lactose are disaccharides, however, they are made up different monosaccharides:
Disaccharide = monosaccharide + monosaccharide
Sucrose = glucose + fructose
Lactose = glucose + galactose

Since they have different structures, their characteristics and behaviour in chemical reactions must differ, too.

Answer:

Cetacean

Explanation:

Let us start with the family Delphinade which is the largest in the Cetacean order, and relatively recent: dolphins evolved about ten million years ago, during the Miocene. Dolphins are among the most intelligent animals and their often-friendly appearance and seemingly playful attitude have made them popular in past and current human culture.
