Metabolically active tissues require a high supply of oxygen and nutrients to support their energetic demands and facilitate waste removal. Extensive capillary networks enhance the surface area for efficient exchange between blood and tissues, ensuring that these metabolic needs are met. Additionally, the proximity of capillaries allows for rapid transport of substances, which is crucial for maintaining homeostasis in active tissues. This vascularization is particularly evident in organs like the heart, brain, and muscles, where metabolic activity is high.

The brain is the most metabolically active tissue at rest, accounting for about 20% of the body's total oxygen consumption and energy utilization. This high metabolic rate is necessary to support brain functions such as synaptic transmission, maintenance of ion gradients, and overall cellular integrity.
Connective tissue generally does not require a lot of energy compared to more metabolically active tissues like muscle or nervous tissue. Its primary functions, such as providing support, structure, and protection, rely more on the extracellular matrix rather than high energy consumption. However, some types of connective tissue, like adipose tissue, can be energy-storing and metabolically active in certain contexts. Overall, the energy demand of connective tissue is relatively low.
Cells that do a lot of work or activity such as muscle cells.
The term vasodilation refers to the dilation or relaxation of the arterioles to allow more blood to an area. It serves to provide more nutrients to metabolically active tissue, or when to the skin as a means to release heat from the body.
Metabolic Weight = Energy expenditure and basal metabolic rate depend on the amount of metabolically active tissue in the body, rather than total body weight. ...Or something like that ;-)
Brown adipose tissue (BAT) tends to decrease as humans age. This type of adipose tissue is more metabolically active and dissipates energy as heat. Its decline with age is associated with a decrease in metabolic rate and a potential increase in the likelihood of obesity.
That is not a straightforward answer because heat isn't produced by body weight but as a waste product of metabolism. The more metabolically active a tissue is, the more heat it will generate. So like muscle tissue will generate more heat than adipose (fat) tissue.
