If the culture does not undergo a color change on the addition of solutions A and B explain how you would interpret this result?
nitrates were not reduced by the organism or the organism possessed such potent nitrate reductase enzymes that nitrates were rapidly reduced beyond nitrites to ammonia or even molecular nitrogen.
Causes the number of chromosomes present in a cell to be reduced by half?
Diploids
Structures which are fully developed in one group of organism but reduced or possibly nonfunctional in a similar group are referred to as?
You may be asking about 'Vestigial' organs.
Explain how the development of a red color on the addition of zinc is a negative test?
zinc reduces nitrates to nitrites. The development of red color therefore verifies that nitrates were not reduced to nitrites by the organism. If the nitrates were not reduced, a negative nitrate reduction reaction has occurred
Which organisms reduced the amount of carbon dioxide and increase the amount of oxygen in the air?
Plants, which are on the first trophic level, can also be referred to as producers or autotrophs.
A structure in an organism that is reduced in size and function and that may have been complete and functional in the organisms ancestors?
Phys
What physical structures were fully developed and functional in an earlier group of organisms but are reduced and unused in later species?
because they did
Anatomical features that are fully developed and functional in one group of organisms but reduced and functionless in a similar group are termed?
Vestigial structures
What is an endangered organism?
An endangered organism can be a plant or an animal whose population has reduced to such a small number that it is very existence is in danger .
If the culture does not undergo a color change on the addition of solutions A and B explain how you would interpret this result?
nitrates were not reduced by the organism or the organism possessed such potent nitrate reductase enzymes that nitrates were rapidly reduced beyond nitrites to ammonia or even molecular nitrogen.
How do oil wastes on the surface of a river affect the organisms?
they cause algae and plants to grow out of control Oil spills effect the bio systems of rivers and lakes very badly. the Biological oxygen demand (BOD) is low. the levels of oxygen present in the water is completely reduced because the oil forms a layer over the surface of water without allowin contact with the atmosphere.
Causes the number of chromosomes present in a cell to be reduced by half?
Diploids
What is reduced diversity in a population?
This questions is two broad and has too many variables to answer effectively.
What reduction division makes the number of chromosomes present in a cell to be reduced by half?
meiosis
What is the term for a reduced often functionless anatomical structure that serves as evidence of an organisms evolutionary past?
vestigial structure
What would be the effect of a meadow environment if the producer organisms dramatically reduce?
If the producers are dramatically reduced then the consumers will also reduce.
