Answer:2,1,3,5,4
Explanation:
Transgenes refer to genes that are artificially introduced into an organism.
Transgenic organisms are those that contain transgenes. These terms are utilized in genetic engineering. The process of gene cloning or the introduction of transgenes enables individual transformations, and this technique is employed to create Genetically Modified Organisms (GMOs).
The following steps are involved:
1. Use restriction enzymes to excise the insulin gene. Additionally, cut the bacterial plasmid with the same restriction enzymes, which are considered endonucleases.
2. Ligase enzyme connects the insulin gene to the bacterial plasmid.
3. The bacterium proliferates, leading to the production of numerous bacterial cells that generate the insulin protein.
4. A bacterium absorbs the recombinant plasmid containing the insulin gene.
5. Human insulin is extracted from the transgenic bacteria.
It's important to note that for gene cloning to occur, there must be a gene to be introduced, a vector, a host cell for multiplication of that gene, a method to transform the organism, and a means to achieve a whole organism.
The plant cell is the fundamental living unit and smallest structure of all plants. Its dimensions and form vary based on its function. It consists of several organelles that play essential roles in its operation.
The correct answers are: (refer to the numbers in the image).
1 corresponds to a vacuole.
2 corresponds to the cell wall (if you examine closely, the arrow points to the green layer, while the yellow layer is the cell membrane).
3 corresponds to a chloroplast.
4 corresponds to mitochondria.
Answer:
Carbohydrate digestion begins in the mouth, while protein digestion takes place in the stomach.
Explanation:
Salivary glands create saliva in the mouth that contains enzymes to convert carbohydrates into sugars.
The stomach lining's digestive glands also secrete enzymes that break down proteins into essential amino acids that the body requires to synthesize proteins.

In the situation outlined, the key step is to evaluate and ensure proper ventilation. A lack of oxygen can cause the heart rate to drop due to insufficient oxygen supply to the heart, making effective lung ventilation the most critical action in this context.
