Answer:
Interdependence is a key concept in ecology. Whilst this can be taught theoretically, some practical fieldwork greatly enhances pupils’ understanding. Almost certainly the fieldwork would entail looking at plant abundance and distribution and, of course, some work with quadrats!
A quadrat is a simple device for marking out a small area. For young children at primary school the quadrat is often a convenient way of focusing a pupil’s attention on a particular small area. At secondary level, pupils should understand how quadrats can be used to sample a larger area. By recording information from a number of quadrats placed within a larger study area, they can obtain a representative sample of the whole area, which may be too big to describe in full.
This article describes how quadrats can be used to help pupils at lower secondary level estimate the relative abundance of plant species. All the information given here refers to frame quadrats. (Point quadrats can be tedious and difficult for pupils to use and are probably best avoided at this level.
There will be to much sugar to drink from the water or you can and go to the hospital.
Answer: The Mpemba effect is a catch-all term for possible cases in which hot water appears to freeze faster than cold water. The phenomenon is temperature-dependent. There is disagreement about the parameters required to produce the effect and about its theoretical basis.
Explanation:
These ones it helps to draw. you have four carbons and each one must have 4 covalent bonds coming off of it, but the double bond will act as a 2 covalent bonds between carbon atoms rather than 1. You should get C4H8. Alternatively the alkene formula can be used (alkenes are molecules with a C to C double bond) which states CnH2n will be the Molecular formula where n is the number of carbons.
