Selective breeding makes use of existing, naturally present gene variants in a species? and the natural process of breeding. Genetic engineering involves a direct change to an organism's genome in the laboratory. Gene variants made through genetic engineering can be passed from one generation to the next.
Yes because the plant's pollination would decrease
As students observe several slides of tissue cross-sections, one simple key they can use to determine if the slides come from dicots or monocots is to analyze the <em><u>vascular bundles</u></em><em><u>.</u></em>
A vascular bundle is described as a portion of the transport system of vascular plants. These bundles are microscopically different in Monocots than they are in Dicots, which will allow students to tell them apart through the tissue slides.
The difference is that monocots contain <em><u>randomly scattered </u></em><em><u>bundles </u></em><em><u>located throughout the </u></em><em><u>stem</u></em><em><u>.</u></em> On the other hand, <u>dicots </u><em><u>have their vascular </u></em><em><u>bundles </u></em><em><u>more neatly organized in </u></em><em><u>concentric circles</u></em><em><u>.</u></em> These microscopic differences can serve as a key to be used by the students to classify the tissue samples they are studying.

Answer:
A string is placed under a solution and a crystal grows on the string because the solution is supersaturated.
Therefore, the correct answer to the question is option B.
Explanation:
A saturated solution is defined as a solution in which there is no more space for the solute to be added. All the words in the solution is been filled with the solute which is been added before and mixed well to fill up all the pores. Supersaturated solution is defined as a solution which has a greater number of solute than it was being capable of holding.
As it is clear from the name supersaturated which means more than saturation. And when string is placed under this solution there are some crystal which grows on the strings because of the solute saturation which is being attached to the string.
