Why dont water striders sink?

Surface tension The top molecule on the water forms a skin that will support dust small creatures and even metal objects like needles when they are place on the surface carefully. Surface tension keeps the water strider afloat, and the water strider long legs only pierce the top skin of the water. A lso, the water strider mass is very little which results in them floating.


How do water striders walk on water?

Water striders use their long legs and low body weight to distribute their weight over a large surface area, allowing them to effectively "skate" on the water's surface tension. This surface tension is created by the cohesive forces between water molecules, which are strong enough to support the water strider's weight without breaking. Their specialized hydrophobic legs also help repel water, preventing them from sinking.


Why surface approches to learning in bad?

Surface approaches to learning can be seen as less effective because they prioritize memorization and rote learning over deep comprehension and critical thinking. Students using surface approaches may struggle to make connections between concepts and apply knowledge in different contexts. This approach may lead to surface-level understanding that is quickly forgotten rather than building a strong foundation for long-term retention and application.


What are the adaptations for water strider?

Water striders have adaptations such as hydrophobic hairs on their legs that trap air, allowing them to float on water's surface tension. Their long legs help distribute their weight and prevent them from breaking the water's surface. Additionally, their bodies are streamlined and lightweight, enabling them to glide effortlessly on the water's surface and capture prey.


A larger surface area makes diffusion happen more quickly?

Yes, it does. The surface area being larger increases the diffusion because there are more protein pathways for molecules to be shipped in and out. As a cell grows, however, the surface area is smaller and diffusion can not happen at a rate fast enough to support the cell. When a cell reaches a certain size, they divide to avoid this problem among others that come with an oversized cell.
