Answer is A. Desirable traits can be selected for and bred in offspring.
Charles Darwin found that there are variations among the individuals of the same species depending on the specific location. These variations may occurred may be due to environmental factors such as availability of food resources, climate differences, and predator-prey relationships.
The experiment with breeding pigeons was aimed to duplicate natural selection through artificial selection. As a result new trait was developed over a period of time. Therefore, desirable traits can be selected and bred in offspring.
Gel electrophoresis is a process or a technique in which fragments of DNA are separated in terms of their sizes.
<em><u>The restriction enzyme is mixed with a DNA sample before the process. The restriction enzyme cut DNA at specific points into fragments which can then be separated based on their sizes on an agarose gel.</u></em>
When current is applied to the gel DNA move towards the positively charged electrode since DNA is negatively charged, with shorter fragments migrating faster through the gel in comparison with large fragments.
Homeotic genes regulate the development of structures. Logically, then, the mutation of this gene must result in improper structure development, such as structures in abnormal places. The answer is C.
Plants go through a process called photosynthesis where they take in carbon dioxide from the atmosphere (as well as water and sunlight), and they turn it into oxygen (so we can breathe) and glucose (sugar)!
