Answer:
Advantage of gene expression in prokaryotes is it occurs faster than in eukaryotes because transcription and translation occur simultaneously in the cytoplasm, and regulation occurs at the transcriptional level. Whereas disadvantage of gene expression in prokaryotes is that there is no post translational modification and low expression of genes.
Explanation:
Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm. To synthesize a protein, the processes of transcription and translation occur almost simultaneously. When the resulting protein is no longer needed, transcription stops. As a result, the primary method to control what type of protein and how much of each protein is expressed in a prokaryotic cell is the regulation of DNA transcription. All of the subsequent steps occur automatically. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level. whereas in eukaryotes, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein. The processes of transcription and translation are physically separated by the nuclear membrane; transcription occurs only within the nucleus, and translation occurs only outside the nucleus in the cytoplasm.
If I’m not mistaking it’s the 2nd one plant cell
The hydroponic method involves growing the tomatoes in a nutrient solution which contains all of the essential elements.
The practise of growing plants without the need for soil is known as hydroponics. Flowers, herbs, and vegetables grown hydroponically are planted in inert growing material and are then given nutrient-rich solutions, oxygen, and water throughout the growing process. The use of this technique results in accelerated growth increased yields, and improved quality. When a plant is growing in soil, the roots of the plant are always looking for the nutrients it needs to survive in order to provide for the plant's needs. If the root system of a plant is provided with direct access to water and nutrients, the plant does not need to expend any energy in order to maintain its own life. It is possible to focus the energy that the plant's roots would have spent obtaining food and water toward the growth of the plant instead. As a direct consequence of this, the development of new leaves and the blossoming of fruits and flowers are both stimulated.

Answer:
The key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N).
Glucose is a hydrocarbon, so it contains carbon (C), and hydrogen (H). It also contains oxygen (O).
Nucleic acids are complex arrangements of carbon, hydrogen, oxygen, nitrogen, and phosphorous.

Answer:
Scientists mostly gain new knowledge through direct observation and applying the scientific method. They would start with a hypothesis and test it, then change it or confirm it. Others would test their confirmation from one point, while the third group would test what the second said. And so on and so forth.
