The answer would be the chloroplast. The cell wall mainly covers and protects the cell's insides.
2. To focus a microscope using the high power lens you must first in low power center the specimen and make sure it is in focus. Then switch to high power and adjust using the fine adjustment or the smaller knob.
3. It prevents dust from settling on the scope and in the lenses.
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.
