<span>The correct answer should be B. The overuse of antibiotics. Since antibiotics as their name says kill biotics, that is, they fight against bacteria, they were used a lot and bacteria started developing resistance to them which is a common thing. Since it's difficult to find new types and the trials last long, new diseases are emerging faster than we can create medicine for them.</span>
Biotic-the decrease of fish can Make the bear population decrease
abiotic-A rapid change in the temperature can make the bear population decline
Answer:
In order to change any part of the cell theory, we will have to prove that the cells are not the basic unit of life. We will have to provide evidence that a cell does not distinguish a living thing from a non-living thing. We will either have to prove the spontaneous generation to be true or have to prove that if not cells, then what are the basic units of life. We will also need evidence to prove that a cell does not arise from a pre-existing cell.
Answer:
The lac operon is an operon, or group of genes with a single promoter (transcribed as a single mRNA). The genes in the operon encode proteins that allow the bacteria to use lactose as an energy source. coli normally metabolise glucose, but if glucose is not available in a new environment, the lac operon can allow E. coli to metabolise lactose, the sugar found in milk using the structural genes beta-galactosidase and lactose permease. The lac operon of E. coli contains genes involved in lactose metabolism. ... It normally blocks transcription of the operon, but stops acting as a repressor when lactose is present. The lac repressor senses lactose indirectly, through its isomer allolactose.
Explanation:
I believe is is hues. This is the property of colors by which they are seen as ranging from red through orange, yellow, green, blue, indigo, and violet, as determined by the dominant wavelength of light. It is more specifically described by the dominant wavelength and is the first item we refer to when adding in the three components of color (hue, value, saturation).
