frosja888 [35]

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.

Three lines of evidence that provide support for common ancestry and evolution are Similar embryology, Molecular homologies, and
grin007 [14]

Answer:

What Is the Evidence for Evolution? Darwin used multiple lines of evidence to support his theory of evolution by natural selection -- fossil evidence, biogeographical evidence, and anatomical evidence.  Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are likely to be evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. ... In humans, the tail is reduced to the tail bone.  

Image result for Three lines of evidence that provide support for common ancestry and evolution are Similar embryology, Molecular homologies, and The Fossil Record.

Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.

Gregor mendel crossbred pea plants for a variety of traits. What did he learn about dominant and recessive traits?
vladimir1956 [14]
Gregor Mendel crossbred two different pea plants. One of the plants had yellow peas (a dominant trait) and one of the plants had green peas (a recessive trait). The yellow pea plant was heterozygous for its trait meaning its alleles will be Yy. The green plant, because it is recessive, was homozygous for its trait, yy. When these plants were crossbred, two of the offspring resulted in heterozygous for the yellow trait and the other two offspring were homozygous for the green trait.
