This control of the internal environment is called homeostasis, and can be observed through the ____________ range of the body's
Semenov [28]

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.

What causes ocean water near the equator to be warmer than ocean water<br> farther north?
ASHA 777 [7]

Answer: The structure and curvature of the Earth results in beams of sunlight glancing off the equator and reaching other areas of the Earth. This means that the areas at the equator receive more energy as the sun's rays hit them directly. :)

The following are the steps for B-cell activation. The steps are in an incorrect order.
Nataly_w [17]

Answer:

4. B cells become activated by interacting with helper T cells.  

1. B cells display antigens in MHC class II receptors on the cell surface.  

2. Antibodies released by plasma cells bind to the antigen so they will be destroyed by other cells of the immune system.

3.B cells rearrange their DNA to create a unique B-cell receptor.  

5. B cells undergo clonal expansion.

6. B cells digest antigens that bind to the antibodies on their surface.

Explanation:

B-cells get activated by interacting with helper T cells when they bind to the antigen to receptors i.e (MHC class II receptors on the cell surface) on the surface of the cell. Series of activities such as release by plasma cells which cause rearrangement of B cells causes the cell to divide and proliferate. The process through which daughter cells arise from a parent cell called clonal expansion.
