The correct answer is option (C) transposons or jumping genes.
Barbara McClintock was an american cytogeneticist. In 1940s, she discovered the phenomenon of transposition brought about by the mobile genetic elements or jumping genes or the transposable elements. These jumping genes refers to a sequence of DNA which can change its position in the genome or the genetic constitution of an organism. She discovered these jumping genes in the Maize for the first time and received the nobel prize in 1983.
Jumping genes form a major portion of the eukaryotic genome. They are often responsible for mutations and associated with the duplication of the genetic material. They also cause the structural changes in the chromosomes like inversion, deletion and translocation which are called the chromosomal aberrations.
We breathe out carbon dioxide to get into the plants and u know they give oxygen and water normally comes to the plant by rain or by us watering plants.
The experiment is not found here but dependent variables may include the growth rate of moths, whereas the independent variable may be the temperature and the control is water.
<h3>What is a dependent variable?</h3>
A dependent variable is the variable that is being modified by the conditions of the experiment (in the example, the growth is dependent on the temperature).
Moreover, a control variable is any condition that remains constant throughout the experiment (in this case, the amount of supplied water).
In conclusion, dependent variables is the growth rate, whereas the independent variable is the temperature and the control is water.

The correct answer for this question is this one: "D.) chlorophyll"Phototropism by definition is the orientation of a plant or other organism in response to light. It can either be toward the source of light ( positive phototropism ) or away from it ( negative phototropism ).Hope this helps answer your question and have a nice day ahead.
A deer gets its energy from the grass it eats. The grass gets its energy from the sun. Anyway back to the deer. The deer then uses its energy to move from place to place to where food is plentiful. When the deer dies it will either have been hunted and eaten by its predators, or it will have died naturally and it will decompose over time.
