Delta is a type of fibre that transmits signals that are interpreted and perceived as pain.
<h3>
Delta fibres</h3>
A delta fibres (also known as A fibres) are a type of sensory fibre. They respond to cold and pressure stimuli, and as nociceptors, their stimulation is perceived as fast/first pain input. Because they are thinly myelinated, they transmit impulses quicker than unmyelinated C fibres but slower than other, thicker myelinated "A" class fibres.
Structure
They have myelinated axons that are thin (2 to 5 m in diameter) and have a moderate conduction velocity, or speed at which a nerve signal moves (2 to 30 m/s). These nerve fibres make up the afferent portion of the reflex arc that causes the body to "draw away" from noxious stimuli because they are linked to acute (sharp) pain (e.g. retracting your hand away from a hot stove). A part of A fibres is also linked to pressure and temperature perception (also known as "cold receptors" in mammals). Contrarily, slow-conducting, unmyelinated C fibres convey gradual, scorching pain.

Answer:
D) compact bone
Explanation:
Compact bone tissue is made of cylindrical osteons that are aligned and travel the length of the bone.
There are four types of heat loss mechanisms: radiation, convection, conduction and evaporation.
Radiation is transfer of heat through electromagnetic waves through space
Conduction is a process by which heat is transferred from the hot area of a solid object to the cool area.
Convection is a process by which heat is transferred from one part of a
fluid (liquid or gas) to another by the bulk movement of the fluid
itself.
Evaporation - when sweating promotes heat loss.
