Answer: These contractions need energy from respiration , and some of this is released as heat. Blood vessels, which lead to the skin capillaries, become narrower - they constrict – which allows less blood to flow through the skin and conserve the core body temperature. This is called vasoconstriction.
Explanation:
It is called cell division
Answer:
The regulation of inflammatory responses at the site of infection is an example of paracrine signaling.
Explanation:
Paracrine signaling is a type of signaling where the cell communicates with their neighbor cells through the secretion of the signaling molecules. These signals move by the process of diffusion through the extracellular matrix.
Paracrine signaling helps in many biological activities in the body such as blood clotting, tissue repair, and reaction against allergens. Transfer of signals across a junction between two nerve cells is an example of practice signaling.
Answer:
Movement
Sensitivity
Respiration
Nutrition
Growth
Reproduction
Excretion
Explanation:
all living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life
