What causes surface tension in water?

Answers

Surface tension forms because of water's cohesive property which results from hydrogen bonding and water's polarity. In cohesion, water molecules bond together and require a substantial amount of energy to break thus creating a high surface tension.

How can students in the photograph use the net to sample the invertebrates in the river.

Answers

Answer and Explanation:

Macroinvertebrate communities show spatial and temporal variability. Many taxons have more affinity for one specific type of habitat.

There are two principal sampling techniques. Qualitative and cuantitave. Qualitative techniques provide data about the river richness and the relationship between the different taxonomic group's abundance. They allow the obtention of the most representative and abundant taxons, estimates their densities, biomass, and calculates the diversity indexes for each sampling site by period. Nets are needed to sample.

Every possible microhabitat must be sampled. The use of the different sampling elements depends on the substrate.

Hard-substrated sites, such as rocks or wood and organic matter, are sampled using a Surber net. The net is placed counter-current. The substrate must be moved and removed up to 10-15 cm deep, checking that animals and the thin sediment lie on the net. Samplings must be done from downstream to the upstream direction, taking replicates per substrate. Invertebrates must be washed on a strainer. Finally, place each of the samples in a plastic bottle, fixate the material with formaldehyde 4% and take it to the lab for its taxonomic identification.

There are two bright stars in a constellation. One of the stars appears red and the other star appears blue. Which of the following is the best explanation for the difference in the stars' color?


The blue star must be moving toward Earth and the red star away from Earth.


The red star must be moving toward Earth and the blue star away from Earth.


The red star must have a greater surface temperature compared to the blue star.


The blue star must have a greater surface temperature compared to the red star.

Answers

Given what we know, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.

How do we explain this?

This has to do with a phenomenon known as the doppler effect. This effect explains how we can perceive a star as red or blue depending on its distance and on whether or not it's moving towards or away from us. When an object moves away from us, the wavelengths of the light it emits are stretched, making the object appear red. However, when it moves towards us, this increases the wave frequency that reaches us and we observe it as blue.

Therefore, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.
