Explanation

 The accurate statement regarding the management of acute infectious diarrhea is that metronidazole is the drug of choice in Clostridium difficile infection.

Clostridium difficile infection (CDI) is a common cause of:

• antibiotic-associated diarrhea
• metronidazole

It is often used as the first-line treatment for mild to moderate cases.

Explanation

Thrombocytes help form blood clots to stop bleeding and to help wounds heal.

It is a tiny, disc-shaped piece of cell that is found in the blood and spleen.

They are pieces of large cells in the bone marrow called megakaryocytes. 

Explanation

• Protein synthesis is a function of cells, specifically ribosomes, which are found in the cytoplasm of cells.
• Bones do not play a direct role in protein synthesis.

Explanation

In multicellular organisms, chemical signaling can be categorized into three basic types:

• Paracrine signaling: This type of signaling involves the release of chemical signals, such as hormones or neurotransmitters, into the extracellular fluid, where they can bind to nearby cells. Examples include histamine release during an allergic reaction and neurotransmitters released by nerve cells.
• Autocrine signaling: In this type of signaling, cells release chemical signals that bind to receptors on their own surface, regulating their own behavior. Examples include the regulation of cell growth and division.
• Endocrine signaling: This type of signaling involves the release of hormones into the bloodstream, which are then transported to distant cells, where they bind to receptors and regulate various physiological processes. Examples include insulin regulating blood sugar levels and thyroid hormones regulating metabolism.

Explanation

The ozone layer is a thin part of the Earth's atmosphere that absorbs almost all of the sun's harmful ultraviolet light.

Ozone is made of O3.

Explanation

The kidneys filter the blood to remove waste products and excess fluids, forming urine.

They play a key role in maintaining the body's fluid and electrolyte balance.

Explanation

Explanation

Germination is the process where a seed begins to grow and develop into a new plant.

It starts when the seed absorbs water, swells, and the embryo begins to sprout.

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

Cytosol is the soluble, fluid portion of the cytoplasm where organelles are suspended.

It plays a key role in metabolic reactions, transport, and cell signaling within the cytoplasm.
