Heat causes a protein to unfold because it increases one or more of these types of energy in the atoms in the protein, thus disrupting the weak interactions that keep the protein in its properly folded state.

a. translational
b. vibrational
c. rotational

Explanation:

Vibrational energy is the energy present in the vibrating system due to the vibration of the atoms in a molecule .

Rotational energy is the energy is in the form of kinetic energy.

It is due to the rotation of an object.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

the correct answer is anaphylaxis.

anaphylaxis is a condition caused by insect bites, foods, medications, manifested by tongue swelling, shortness of breath, vomiting, low blood pressure. it sometimes may occur without an obvious reason. it is treated with epinephrine injection.other tretments include antihistamines and steroids,
