The answer is <span>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 + </span>galactose
Since they have different structures, their characteristics and behaviour in chemical reactions must differ, too.
An isotonic solution is a solution in which the amount of dissolved material is equal both inside and outside of the cell. Water still flows in both directions, but an equal amount enters and leaves the cell. Hope this helps. :)
The answer is "D"
The body's first line of defense is also known as Innate immunity and incudes mucous membranes. Both the intact skin and mucous membranes of the body offer a high degree of protection against pathogens.
A good example is the mucous membrane of the respiratory tract. It is lined up with cilia and covered with mucus. The coordinated beating of the cilia drives the mucus up to the nose and mouth where the trapped bacteria can be expelled.
(Lymph nodes and white blood cells belong to the second line of defense, not the first)
That would be A.
Dicots grow flowers with petals in multiplies of 4 and 5, monocots in multiples of 3. See the attached pic:)
They're celled subsistence farmers, their farming practice is subsistence farming, where most of the product they grew or reared are for themselves and their families, they usually don't take the products to the markets for commercial purposes, instead those who do that are practising commercial farming.
