Active transport require the cell to expand energy whilst Passive transport require no energy from the cell in active transport.
Passive Transport moves molecules across membrane without the use of energy by the cell.
-Simple diffusion
-Facilitated diffusion
-Osmosis
Active Transport uses energy (ATP) to move molecules across membrane.
-Protein pumps
-Exocytosis
-Endocytosis (Phagocytosis & Pinocytosis)
Answer: "homeostatic (dynamic equilibrium) range"
Homeostasis can be observed through the "homeostatic range (pre-set limits)" of the body's pH, temperature and blood glucose.
Explanation:
Homeostasis is the control of internal environment , physical and chemical conditions maintained by the living systems. A body takes control of its internal environment in spite of external forces interruptions. It can be defined as the body's defensive mechanisms.
Homeostasis is maintained and controlled by the nervous system.
Homeostasis is for optimal functioning of the internal environment such as body pH, body temperature, fluid balance, chemical ions balance (calcium, sodium and potassium) and blood glucose.
Body temperature is normally about 37.5° C (98.6° F).
Salt concentration in body fluids is normally about 0.9%
Blood glucose is normally about 10 mg/ml.
A disturbed (imbalanced body as a result of external forces) body regains its haemostasis balance by
Activating reflexes that fight the disturbance and maintaining behaviours to counteract the disturbance.
V final = (Mass x V initial) + (Mass x V initial) /m + m
V = (0.04 x 300) + ( 0.5 x 0 ) / 0.04 + 0.5
V = 22.2 m/s
No. they were all joined together and then they separated
