Answer:
Proteins.
Explanation:
Proteins (also called polypeptides) are large biological molecules which consists of one or more chains of amino acid. Proteins perform a series of functions which are catalysing metabolic reactions, DNA replication, providing structure to cells, transport molecules from one location to another within an organism etc.
Collagen consists of amino acids bound together to form a triple helix of elongated fibrils. It can be found in the skin, ligaments etc.
Enzymes are globular protein molecules which have the tertiary structure. They are generally rounded, "squashed" ball shape. Others include fibrous proteins which are long thin structures and are found in muscles and hair.

W = m gm = 55.0 x 1.62 = 89.1 N
Answer:
114.23g
Explanation:
Mass = xg
Mole = 0.334 mol
Molar mass of Sucrose
(C = 12, H = 1, O = 16)
C12H22O11
(12×12)+(1×22)+(16×11)
144 + 22 + 176
342g/mol
Mass = No of mole × Molar mass
Mass = 0.334 × 342
Mass = 114.228
Mass ≈ 114.23g
Answer:
The new volume of the gas is decreased, to 0.329 L
Explanation:
Step 1: Data given
Volume of oxygen = 500 mL = 0.500 L
Pressure = 1.3 atm
Temperature = 25.0 °C
Temperature increases to 29.0 °C
New pressure = 2.0 atm
Step 2: Calculate new volume
p1*V1/T1 = p2*V2/T2
⇒with p1 = the initial pressure = 1.3 atm
⇒with V1 = the initial volume = 0.500L
⇒with T1 = the initial temperature = 25 °C = 298 K
⇒with p2 = the new pressure = 2.0 atm
⇒with V2 = the new volume = TO BE DETERMINED
⇒with T2 = the new temperature = 29 °C = 302 K
(1.3 * 0.500)/298 = (2.0 * V2) /302
0.0021812 = 2.0V2 / 302
V2 = 0.329 L = 329 mL
The new volume of the gas is decreased, to 0.329 L
