Why water insects need to be on the water surface of the water?

Water, H2O, forms four hydrogen bonds per molecules with other molecules in a tetrahedral arrangement.
A hydrogen bond is an attraction between hydrogen atoms and any highly electronegative atom (N, O or F). The attraction is a result of a small positive charge on hydrogen and a small negative charge on oxygen (or N or F), due the the larger nucleus of oxygen. A larger nucleus contains more protons, which will attract electrons more strongly than the single proton of hydrogen. The electrons in the H-O bond therefore sit closer to oxygen than hydrogen, giving each their small charges.
This hydrogen bonding is especially strong at the surface, where there are no water molecules above it so it forms more concentrated hydrogen bonding, creating "surface tension". The surface tension is a bit like a thin piece of tissue paper (though obviously not as strong) in that you can rest something on it as long as it is not too heavy for its size (ie, as long as it does not exert too much pressure on the tissue paper). A water bug weighs very little, and rests quite long areas of its legs on the surface of the water. The pressure the insect exerts on the surface of the water is not great enough to break the hydrogen bonding that makes up the surface tension, so the insect cannot stink.

∙ 10y agobecause cats can eat insects it mean that they can be less easily spotted and people are less likely to hurt them as they can see them before they are going in the water they also cannot stand on them if they are at the bottom and can be Haywood living with their mutations so they can eat them whole

Some insects can stand on the surface of water because water?
Some insects can stand on the surface of water because water is usually adhesive and cohesive. This is made possible by the molecules in the water.
Which property of water allows insects to walk on water?
Certain insects (ones with a very light weight) are able to walk on water as their weight does not break the surface tension of the water. Water has a very high surface tension, therefore easily breaking and not supporting weight above a certain limit.
What are the insects that use their skin to walk across thd surface of the stream?
Insects that are able to walk across the surface of water are called water striders. Water striders make use of the high surface tension of water together with their long, hydrophobic legs to stay above water.
How are small insects able to walk on the surface of water?
The oil on their feet is strong enough to repel the water and there weight is spread out enough that when their feet touch the water, the oil and the water repel each other like when you pour oil on water the oil floats on the top... same principle
Why some insects can walk on water without sinking?
most insects can not float on water, but it depends. A bee will drown if it gets its wings in the water (along with most, if not all, winged insects), but some insects are specifically made to stand on water and catch gnats that are around.

Why is surface tension helpful to some oragisms?
Many insects and microscopic organisms need to be in direct contact with the air to feed, live, and reproduce. The surface tension on water allows many insects to "walk" across the surface making the capture of prey much easier. During the hatching cycle, many insects larvae come to the surface of the water, using the surface tension for support while releasing the larvae inside.
How do insects run on water answer with resp to surface tensionpls?
due to surface tension
How do insect use locomotion on water?
"Many of these insects are adapted to utilize the surface tension of water for locomotion. The surface tension of water makes it possible for some insects to stand on water and remain dry."
What property of water supports gliding insects?
Surface tension
How do living things insects use surface tension?
Surface tension is most important to insects who land on water. Because of cohesion, the hydrogen bonds in water make each individual water molecule "sticky."
How do things like insects use surface tension?
Surface tension is most important to insects who land on water. Because of cohesion, the hydrogen bonds in water make each individual water molecule "sticky."
How do living things like insects use surface?
Surface tension is most important to insects who land on water. Because of cohesion, the hydrogen bonds in water make each individual water molecule "sticky."
Which property of water allows small insects to walk on its surface?
Its mostly due to Surface Tensions, keeping them balanced on the water.
What is a sentence with the word surface tension?
Some insects can stand right on the surface tension of the water.
