The secret weapon of any insect that walks on water is in its body hair. Water striders and fishing spiders both have legs and bodies that are covered in a thick layer of tiny hairs. These hairs trap air in between them, repelling water and helping them keep the bugs afloat. If the insect were to get wet through, it wouldn’t be able to walk on the surface of the water anymore.
Three cases happen when a light wave strikes an object. Light waves can either be: absorbed, reflected or refracted. The differences are as follows:
a. Absorption - light stops at the object causing it to appear dark or opaque.
b. Reflection - this could happen either in a smooth or rough surface. On a smooth surface, for example mirror or glass, light bounces off the surface at angle equal to the incoming light wave. On a rough surface e.g. earth, light bounces at many angles because the surface is uneven.
c. Refraction - light goes through the object and bends at an angle. Typical thing you see when diamond or water is struck by light.
Answer:
a. lycophytes is the correct answer.
Explanation:
Microphylls are found in lycophytes.
lycophyte is a vascular plant, they have a unique type of leaves called microphylls.
The lycophytes belong to the division of Lycophyta, they are seedless plants and have vascular tissue.
The leaves(microphylls) present in the lycophyte have a single vein that is unbranched and narrow, which provides the water to the leaf and supplies nutrients to other parts of the plant.
Answer:
