"In proteins, structural segments called ____ provide flexibility that allow parts of the protein to bend, fold, or move."
Rainbow [258]

Answer:

The correct answer is "random coils".

Explanation:

Random coil is a type of polypeptide secondary structure comprised of conformation that do not follow an established conformation but rather are oriented randomly. These random coils conformations provides flexibility to proteins, since the lack of a particular structure (such as alpha helices or beta sheets), allows the protein to bend, fold or move.

If one sample food contains 200 cal in another contains 300 cal, which statement applies?
Advocard [28]

<u>Answer</u>:

The food containing 200 calorie have less potential energy than the food containing 300 calorie

<u>Explanation</u>:

The potential energy content of a food material is its stored energy content which is in the form of chemical bonds. This energy can be measured through the combustion of food material inside a calorimeter. A calorimeter is an instrument which is used to measure the total calorie content of the food or other biological samples by measuring its heat content. A Calorie is unit of energy which is in form of heat.

The food material containing carbohydrates proteins and fats have energy in form of chemical bonds.  On the breaking of bond inside the body, energy is released as in the case of glucose breakdown also known as glycolysis.  

The energy released from glycolysis is used to synthesize high energy containing phosphoanhydride bonds. These ATP molecules are a further breakdown in the system to provide energy to the cell to perform various activities.

A mixture of oxygen, hydrogen, and nitrogen exerts a total pressure of 378 kPa. If the partial pressures of oxygen and hydrogen
NARA [144]

As we know that

<span>P total = pO +pH +pN</span>

<span>so</span>

P = P1 + P2 + P3

378 kPa= 212 kPa + 101 kPa + P(H2)

P(H2) = 65 kPa

partial pressure is 65

so correct option is A 

hope it helps
