Answer:
Agriculture
Explanation:
Genetic engineering can be defined as the use of genetic techniques aimed at modifying the genome of living organisms, thereby being used to develop Genetically Modified Organisms (GMOs). In the USA, genetic engineering methodologies have been used in agriculture to improve crop yields and reduce costs (for example, by reducing the need to use pesticides). Some of the most important genetic engineering techniques that nowadays are being used in agriculture research include biolistic transformation, <em>Agrobacterium</em>-mediated transformation, the CRISPR-Cas9 genome editing system, etc.

Answer:
The stigma, a female structure which collects pollen and passes it to the ovary
Explanation:
<u>The structure represented by the letter A in the diagram is the stigma.</u>
The <u>stigma of a flower represents part of the female reproductive structure</u>. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.
