Explanation

The intestinal parasite that causes amoebic dysentery in humans is Entamoeba histolytica.

Amoebic dysentery is a disease caused by the protozoan parasite Entamoeba histolytica. 

Explanation

Robert Koch established the germ theory of disease by demonstrating a causal relationship.

Between specific microorganisms and particular diseases, most notably with his research on anthrax.

Explanation

 Lodicules are small, scaly structures found at the base of a grass flower.

They are essentially modified parts of the perianth, which is the non-reproductive part of a flower.

The perianth consists of sepals and petals (or tepals if they are undifferentiated).

In grasses, the perianth is reduced and modified into these small scales called lodicules.

Explanation

Arthrobotrys is a soil-dwelling carnivorous fungus that traps and digests nematodes using specialized hyphal structures.

It plays a role in biological control of harmful soil pests.

Explanation

Haustoria are specialized structures produced by parasitic fungi.

They penetrate the host cells and absorb nutrients directly from the cytoplasm. 

Explanation

A glycosidic bond is a covalent bond that links two monosaccharides to form a disaccharide (e.g., glucose + fructose = sucrose).

This bond is formed through a condensation (dehydration) reaction, releasing a molecule of water.

Explanation

This refers to the loss of water through the cuticle, the waxy layer on the surface of leaves. 

Sources consistently state that approximately 5-7% of total transpiration occurs via the cuticle. 

Explanation

Secretin is a hormone released from the small intestine that stimulates the liver (hepatic) and pancreas to secrete bile and bicarbonate-rich fluids.

It helps neutralize stomach acid in the duodenum for proper digestion.

Explanation

Microfilaments (mainly made of actin) are responsible for cell movements like cyclosis (cytoplasmic streaming) and amoeboid movement.

They help in changing cell shape, enabling movement in amoebas and streaming in plant cells.

Explanation

Jaundice occurs when bile pigments (mainly bilirubin) accumulate in the body instead of being excreted.

It leads to yellowing of the skin and eyes, often due to liver or bile duct issues.
