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.
Answer:
What is a monomer?
A monomer is a molecule that can react together with other monomer molecules to form a larger polymer chain or three-dimensional network in a process called polymerization.
What is a polymer?
Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded. Some polymers bend and stretch, like rubber and polyester.The term polymer is often used to describe plastics, which are synthetic polymers.
Pyruvate undergoes fermentation if no oxygen is present. This is called anaerobic reaction. Can undergo lactic acid or alcoholic fermentation.
The answer is a:lentil seed pattern is affected by codominance.
Codominance is a form of inheritance in which two different alleles of a gene are both expressed.
In this example, one allele of the gene is responsible for dotted seeds and the other is responsible for spotted seed. If both these traits appear in heterozygous plants, then it is codominance. Let's take for example flowers - after crossing red flower plant with white flower plant, heterozygote offspring would red purple-white flowers, which means it express both traits and it is codominance.
This is not complete dominance because in this case, heterozygote would express a dominant trait (in the example of red and white flowers, heterozygote will be with red flowers). This is not incomplete dominance as well, because in that case, the heterozygote would have some intermediate trait (in the example of red and white flowers, heterozygote will be with pink flowers which is intermediate color between red and white).
