SNI Easter Quiz

Correct!
Consisting primarily of silicon dioxide, the skeleton of a radiolarian features silicon dioxide supports radiating outwards from an endoskeleton. This is made of the same material and comprises a spherical, perforated capsule or several such capsules in a concentric arrangement.

Leeches belong to the category of ringed worms and are closely related to the earthworm. The genus of leeches comprises some six hundred species worldwide, which prefer stagnant or slow-flowing bodies of water – such as ponds, pools or streams – with clear water and a constant water level. Leeches have been used in medicine since the Middle Ages, and the worms’ saliva contains substances with anticoagulant and anti-inflammatory properties.

Correct!
Like all other insects, mosquitoes have compound eyes made up of a large number of individual eyes, allowing them to assemble an image of their surroundings from the individual picture elements. The image is not as crisp as we are used to, but it has enormous depth of focus. Insects can detect extremely small movements very quickly over a large area.

Correct!
Downy mildew causes considerable damage to the viticulture industry. Its spores can enter the plant through stomas in the leaves. The SNI’s Nano Imaging Lab is involved in projects investigating the infection process and ways to reduce the need for fungicidal treatments by using fungi-resistant grape varieties.
