Answer: True

Explanation: The plasma membrane is a membrane the protects the cell and its environment. It regulates what goes inside and what comes out of the cell. .

Plasma membrane as a structure composed of multiple components, including phospholipid bilayer, carbohydrates, and other lipids. The phospholipids possess one head and two tails. The head is basically polar and hydrophilic (water-loving) while the tails are non-polar and hydrophobic (water-fearing).

The plasma membrane is decorated with proteins. Some protiens are extrinsic proteins that run halfway through the membrane, while others are called integral proteins that go entirely through the membrane. The function of these proteins is to serve as channels to allow the molecules to enter and leave the cell.

The _____ system is a communication network closely linked to the nervous system.
choli [55]
The answer is endocrine system. It includes all of the glands of the body and the hormones produced by those glands. The glands are controlled directly by stimulus from the nervous system as well as by chemical receptors in the blood and hormones produced by other glands. By regulating the roles of the organs in the body, these glands help to continue the body’s homeostasis. Cellular metabolism, reproduction, sexual development, sugar and mineral homeostasis, heart rate, and digestion are amid the several processes controlled by the actions of hormones.

Due to the fact that we possess enzymes that break down the alpha linkages in starch, the glucose molecules that make up amylose
dedylja [7]

The answer is: A. True

Complex sugars or polysaccharides are composed of basic units called monosaccharides that are linked via  glycosidic bonds. Glycosidic bond is formed through condensation reactions (water is released) that occur between a hydroxyl (OH) oxygen atom on one sugar and the α-anomeric form of C-1 on the other. There are are two types of glycosidic bonds:

- 1,4 alpha ( the OH is below the glucose ring)

- 1,4 beta glycosidic bonds (the OH is above the glucose ring)

Amylase is an enzyme that breaks down starch into smaller glucose molecules, it act on α-1,4-glycosidic bonds and it works in mouth where the digestion begins (salivary amylase) . Maltase breaks down maltose into glucose; sucrase, breaks down sucrose into glucose and fructose; and lactase, which breaks down lactose into glucose and galactose work in small intestine and also act on α-1,4-glycosidic bonds.
