Wat is het belang van stilistische middelen zoals symbolen in de literatuur?
Symbolen worden voornamelijk gebruikt in taal en literatuur om op een subtiele manier een idee te weergeven met daarbij een diepere betekenis. Het kan zo zijn dat het symbool herhalend gebruikt wordt om iets anders te representeren zonder dat het expliciet benoemt hoeft te worden. Het effect hiervan is dat de boodschap genuanceerder over komt, en dat een schrijver met nieuwe en meer creatieve manieren zijn thema kan benadrukken.
Are our actions a product of our genes; to what extent is behavior genetic? What about innate behavior?
There have been a lot of discussions whether a certain trait or behavior is due to nature or nurture. Recent studies in psychology through rigorous experimental design have suggested that it is a combination of both - but it varies greatly in percentage for a specific trait. For example, according to a twin study conducted by Bouchard (1990) that looked at hundreds of genes, height is 86% heritable and IQ 69% but these numbers have varied by quite a bit in other experiments. The study of heritability is therefore enormously complex as there are often a lot of genes that may trigger a predisposition to a certain behavior. A lot of current research in the field of psychology investigates whether there are genes correlated with certain behaviours. Is there a gene for intelligence or depression? An interesting thing to think about are evolutionary behaviours such as the disgust response: It is extremely hard to control your own disgust to something grotesque, but in a social setting you may override your response or saying "blehg" simply because it is impolite. To me this is an interesting example of how 'nurture' (culture) and 'nature' (innate behavior) interact with one another to establish a well cultivated response.
Describe and name the process in which water vapour is lost from the stems and leaves of plants.
The process in which water vapour is lost from the stems and leaves of plants is called transpiration. Plants take up water through their roots because they need it for photosynthesis. When the water enters the plant is turns into vapour as it absorbs light energy; this creates a difference in pressure between the leaves and roots. The low pressure in the roots and high pressure in the roots causes a transpiration stream from the roots to the leaves. The leaves finally releases the water vapour through tiny pores called stomata in a continuous process.
