The question given here is not complete, there is no example of biotechnology give. In this condition any example can be taken here, plant biotechnology is taken as an example.
Answer: The plant biotechnology can be defined as a field that helps in agriculture. The plants and crops are modified in such a way that the crops produced are of great importance.
Explanation:
The example is genetically modified plants. The genes of the plants is modified in such a way the products produced are disease resistant, drought resistant and have high nutritive value.
These crops are not naturally present in the environment it is produced by the genetic manipulation which is the work of plant biotechnology.
There are many disadvantages associated with this techniques such as horizontal gene transfer, loss of insects, and the long term effect of these plants cannot be predicted.
Hello,
The chemical change that takes place is water and electrolytes are removed from the food being digest.
Thanks for using brainly :)
Answer:
The correct answer are option A. "A microbiologist with the U.S. Geological Survey grew crescent-shaped fungal spores in a lab on refrigerated plates" and option C. "A specialist with the New York State Health Department detected crescent-shaped fungal spores when examining a sample swabbed directly from a living bat with a white nose".
Explanation:
Doctor Blehert and Doctor Behr are two scientists that are studying the relationship between fungal disease and the development of the bat white nose syndrome. In order to prove that bat white nose syndrome is caused by a fungal disease Blehert and Behr first took samples in the field and later analyzed the samples in the laboratory. First, a specialist with the New York State Health Department detected crescent-shaped fungal spores when examining a sample swabbed directly from a living bat with a white nose. Later, the samples taken from the shaped fungal spores were grew in the laboratory on refrigerated plates by a microbiologist with the U.S. Geological Survey. After analyzing the samples, the scientists conclude that the bat white nose syndrome is caused by a fungal disease.
