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

Haustoria are specialized structures produced by parasitic fungi.

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

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

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

The breakdown of alveoli in the lungs is called Emphysema. 

Emphysema is a lung condition where the small air sacs (alveoli) are damaged, causing them to break down and merge into larger spaces, reducing the surface area available for gas exchange. 

Explanation

 Sweet peas are annual climbing plants with fragrant, butterfly-shaped flowers. 

They are part of the genus Lathyrus within the Fabaceae family. 

The name Lathyrus is derived from the Greek word for "pea," and odoratus means "scented". 

They are cultivated for their beautiful and fragrant flowers.

Explanation

A protostome is an animal where the first opening that forms during embryonic development (the blastopore) becomes the mouth.

While the second opening develops into the anus. 

Explanation

To prepare 250 cm³ (or 250 mL) of a 1 M NaOH solution, you need 10 grams of NaOH.

This is because the molar mass of NaOH is 40 g/mol, and a 1 M solution contains 1 mole of solute per liter of solution.

Therefore, 250 mL (0.25 L) of a 1 M solution would require 0.25 moles of NaOH, which translates to 10 grams (0.25 moles * 40 g/mol). 

Explanation

The correct unit of the rate constant for a zero-order reaction is mol dm⁻³ s⁻¹ or mol L⁻¹ s⁻¹.
