Explanation

Nervous coordination involves the transmission of electrochemical signals.

It is also known as nerve impulses or action potentials, through the nervous system.

This allows for rapid communication and coordination between different parts of the body.

Explanation

A stimulus is detected by a receptor.

It is a specialized cell or structure that converts the stimulus into an electrical signal that can be transmitted to the nervous system.

Explanation

A response is the organism's reaction or adaptation to a change in the environment.

Such as a change in temperature, light, or sound.

Explanation

ADH (Antidiuretic Hormone), also known as vasopressin.

It is released by the hypothalamus in the brain and stored in the posterior pituitary gland.

ADH regulates water reabsorption in the kidneys, leading to increased water retention and decreased urine production.

Explanation

• Selective reabsorption primarily occurs in the proximal convoluted tubule (PCT).
• To a lesser extent, in the distal convoluted tubule (DCT), where essential nutrients, water, and ions are reabsorbed back into the bloodstream.

Explanation

The dermis is the middle layer of the skin.

It contains a network of blood capillaries that supply oxygen and nutrients to the skin cells.

The dermis also contains hair follicles, sweat glands, and sebaceous glands.

Explanation

The kidneys are enclosed in a membrane called the peritoneum, which is a thin layer of tissue that lines the abdominal cavity.

The peritoneum supports and protects the kidneys, as well as other organs in the abdominal cavity.

Explanation

Thermoregulation is the ability of an organism to maintain its body temperature within a suitable limit, despite changes in the external environment.

This is a crucial function that allows cells, tissues, and organs to function properly.

Explanation

Halophytes are plants that are adapted to grow in coastal areas with high salt concentrations, such as salt marshes, mangroves, and seashores.

They have specialized structures and physiological adaptations to survive in these saline environments.

Explanation

• Removal of extra liquid water from plants is called guttation.
• The removal of water as vapor is transpiration.
• In biology, the general removal of excess water from the body is called excretion.
• In Chemistry: Known as Dehydration, the removal of a water molecule from a compound.
