What is the difference between a cell drawing and a zone diagram?
A zone diagram demonstrates the layout of different types of tissues at a low magnification. A cell drawing shows individual cells viewed at a high magnification.
What type of organism likely to suffer the most from the effects of biological magnification?
tertiary consumer
What is the process concentrations of harmful substances increase in organisms at higher tropic levels in a food chain known as?
biological magnification -teddybearr
Why is it important to record magnification used when drawing cells seen using a microscope?
because cells were unable to be seen without the aid of an electron microscope
What are the causes of biological magnification?
they can destroy the nutrients in soil thus creating dangerous plants which can be fatal to the animals that eat them
What is the formula for calculating total magnification on a microscope?
To determime total magnification of a drawing you devide the dimensions of the drawing by the dimensions of the real object or specimen drawn Mathematically Magnification =Dimensions of drawing/dimensions of specimen
If the size of a cell under high power is 20 microns and the drawing is 10 cm long what is the magnification of the drawing?
10cm is 100,000um. 100,000/20 is 5000 magnification
In Biology what does the term drawing magnification mean?
In biology you are often required to make a drawing of an organism or structure. The drawing should include the magnification or how many times larger (or smaller) the drawing is than the actual object. You can calculate the magnification by dividing the size of the object drawn on the page by the size of the actual object. Don't forget to make sure they are in the same units! for example: drawing 5 cm/ actual cell 5 um X 10,000 um/1 cm = 10,000 x magnification
What is the difference between a cell drawing and a zone diagram?
A zone diagram demonstrates the layout of different types of tissues at a low magnification. A cell drawing shows individual cells viewed at a high magnification.
What type of organism is likely to suffer the most from the effects of biological magnification is?
tertiary consumer
How did biological magnification play a role in the disappearance of the peregrine falcon?
The use of the pesticide DDT.
Which type of organism is likely to suffer the effect of biological magnification most?
tertiary consumer
What type of organism likely to suffer the most from the effects of biological magnification?
tertiary consumer
Define biological magnification and explain why humans are often more severely affected?
Biological magnification: the process by which pollutants become more concentrated in successive trophic levels of a food web (accumulation of pollutants in fatty tissues of a predator) Humans are often more severely affected than earlier trophic levels due to biological magnification. The ppm (parts per million) is the unit of measurement for concentration of chemicals like pollutants and augment to a degenerative degree in higher trophic levels. Humans are consumers and higher in the food web, thus subject to the malicious effects of biological magnification of toxins.
What can people do to solve the problem of biomagnification?
we can solve the concentration of biological magnification if produce less DDT
Formula for finding the magnification of a cell?
Its M = D/A M is the Magnification D is the Drawing's Size A is the Actual Size so to find the actual size we replace A with X etc...
Peregrine falcons and other birds suffer from increased concentrations of toxins in a process know as?
Biological Magnification
