<span>Magnetic resonance imaging
is a technology that uses magnetic fields and radio waves to produce high
quality 2 or 3 dimensional images of the brain structure without using
radioactive tracers and ionizing radiation. The magnetic resonance intensity is
proportional to the density of the protons in various tissues.</span>
What are the questions that go with the model?
Scientists often experiment with Brassica plants because they have a relatively short growth period, and they may represent model organisms for genetic studies.
<h3>Why use the Brassica plants in genetic studies?</h3>
Brassica plants are considered model organisms in genetic studies because they have a short period of growth (around 30 days), which allows the analysis of a high number of generations in less time.
Moreover, the genome of Brassica plants contains 24 Gigabases (24 billion nucleotide bases), which is a high number to be considered a model organism in genetic studies.
In conclusion, scientists often experiment with Brassica plants because they have a relatively short growth period, and they may represent model organisms for genetic studies.

Answer:
Hypotonic
Explanation:
Tap water contains a lot of solutes and ions that are absent in distilled water. The solution that has more solutes (more dissolved solids) will be the <em>hypertonic</em> solution.
Here, distilled water has no solutes, making it <em>hypotonic</em>.
Answer:
D
Explanation:
This is the more likely explanation, as there must be a limit to leg length in an animal that has to run very fast and strain their muscles and bones to the limit to do so.
As for the other options, there is no evidence to conclude that the genes that are involved in cheetahs leg length do not undergo mutation because the population exhibits a variety of leg lengths. Neither can we conclude that there are any isolated subgroups in the pupulation. Natural selection does act upon the traits involved in predation, as the question starts by saying that the faster a cheetah can run the more likely it is to capture its prey.
