I believe the example of an environmental variation in the above question is, A. Marge dyes her hair blue. Variation represents any difference between cells, individual organisms, or groups of organisms of any species caused by either genetic differences or by the effect of environmental factors. Environmental variation is the ability of an organism to alter its phenotype depending on environmental conditions.
Answer:
take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA. ... During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines
Explanation:
which translates mRNA. tRNA is the link between the two other types of RNA.
Simulations generally involve a simple design. In contrast, the world is a very complex system. Many events, such as how we farm, can disrupt the world's delicate balance. Simulations do not take into account the varied interactions that affect events in the real world.
Answer:
One of the factors for the development of pyelonephritis, in addition to E. coli, is urinary retention and reflux (option a).
Explanation:
Pyelonephritis is an infection of the upper urinary tract caused by bacteria in the urine, such as Escherichia coli.
Under normal conditions, urine in the urinary bladder is aseptic, that is, without bacteria. The presence of bacteria in the urine indicates a urinary infection.
Urinary retention is the limitation of the expulsion of urine from the bladder. This promotes:
- <em>An increase in the amount of bacteria present in the bladder.
</em>
- <em>The pressure generated by urine retention causes the bladder to generate a retrograde flow - reflow - towards the ureters, leading the bacteria to the kidneys.
</em>
The result of urinary retention and reflux - when bacteria are present - is an infection in the upper urinary tract, called pyelonephritis.
