We will attempt to introduce a gene responsible for the resistance to the antibiotic ampicillin.
Bacterial transformation is a molecular technique widely used in genetic engineering. Its basis involves the introduction of a foreign DNA into a host organism. This will result in the expression of a foreign gene by the host bacterium. In this example, our host organism is a bacterium who is sensitive to the antibiotic ampicillin. By introducing a gene for resistance to this antibiotic, the bacterium will become ampicillin resistant.
Answer:
(a) Outside the Cell
(Is the opposite of what takes place inside the cell)
[Na+] high
[glucose] low
(b) For glucose-sodium cotransporter
{glucose} down
{Na+} down
1. {Na+}
flows downward to its electrochemical gradient.
2. {Glucose}
flows across its concentration gradient.
(c) Inside the cell
(Is the opposite of what takes place outside the cell)
[Na+] low
[glucose] high
The cell organelle which serves as the site of protein synthesis in the cell is the ribosomes.
<h3>What are cell organelles?</h3>
Cell organelles are membrane-bound structures whivh are found embedded within a cell cytoplasm and which perform specific functions for the cell.
Some cell organelles include:
- mitochondria
- ribosomes
- lysosomes
- Golgi bodies
The ribosome is a cell organelle which functions as the site for protein synthesis in the cell.
Therefore, the site of protein synthesis in the cell is the ribosomes.

<span>By producing melanin (pigment), the skin protects the underlying structures from ultraviolet light's harmful rays while producing vitamin D, which works with calcium for multiple body processes.

Vitamin D is produced by the skin when it is exposed to the sunlight. Ultraviolet B (UVB) is the part of the sun's rays that affects the skin to produce such vitamin.
Answer:
The correct answer is option b, that is, four-field approach.
Explanation:
Anthropology refers to the study of human beliefs, behavior, and adaptations. In order to completely comprehend any aspect of human behavior, the field of anthropology adopts a four-field approach. The four sub-disciplines of anthropology are archaeology, cultural anthropology, biological anthropology, and linguistic anthropology.
In archaeology, materials are used generally from past cultures, in order to understand and illustrate human behavior and adaptive strategies via time. Biological anthropology refers to the study of humans as biological species, the research areas comprise diversity in modern human populations, human evolution, and medical anthropology.
The cultural anthropology explores patterns of behavior and belief in historical and contemporary cultures all over the globe. The linguistic anthropology studies and documents languages in terms of acquisition, structure, and use in the transmission of culture. As can be seen that each of the sub-disciplines focuses on distinct characteristics of human adaptation, however, when taken together in a four-field approach it offers a powerful tool for gaining a complete understanding of any aspect of human behavior.
