Give one example of a molecule using passive transport and one example of a molecule using active transport.

1 answer:

6 0

One example of passive transport is diffusion, when molecules move from an area of high concentration (large amount) to an area of low concentration (low amount). Molecules are said to naturally flow down their concentration gradient

Scientists often experiment with Brassica plants

8090 [49]

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.
