Answer: Skin; Brain, GSA - General Somatic Afferent
Explanation:
<em>Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his </em><em><u>skin</u></em><em> to his </em><em><u>brain</u></em><em>. This information would travel via </em><em><u>GSA </u></em><em>neurones.</em>
The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.
This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.
Answer and Explanation: In enzyme kinetics, one constant describing enzyme activity is <em>Maximal Velocity</em> (Vmax). It indicates how fast an enzyme can catalyze the reaction. It is dependent on substrate concentration.
As the muscle is an organ which needs a great amount of energy, the enzyme glycogen phosphorilase is very active on the organ, compared to the liver, where glicose is stored. So, the Vmax of glycogen phosphorylase expressed in muscle is faster than when expressed in the liver, means the enzyme in muscle has a bigger concentration of substrate and therefore will reach Vmax faster, i.e. will be significantly larger.

Explanation:
The mass of vascularized connective tissue that temporarily forms during wound healing is called the granulation tissue.
Granulation tissue refers to the reddish connective tissue that forms around the surface of the wound during wound healing. It is associated with the formation of the new blood vessels renedering it a red color and delivers the nutrients to the tissue. It is primarily composed of a tissue matrix consisting of different types of cells which are associated with various functions like the formation of the matrix, protect against infection and the formation of the blood vessels which is called the vascularization. Fibroblasts are present in the extracellular matrix of the granulation tissue.
The key evolutionary development of animals seen for the first time in sponges is that of Multicellularity. A Multicellular organism has a longer lifespan than an unicellular organism and since it has multiple cells, it can perform more functions. Sponges do not have distinct circulatory, respiratory, digestive, and excretory systems – instead the water flow system supports all these functions.
