Answer:
All protein contain unique three dimensional structures
Explanation:
D) is the answer
Answer:
Gram positive; Contain thick mesh wall of peptidoglycan in cell wall.
Explanation:
- Gram staining technique is used to separate the gram positive and gram negative bacteria on the presence or absence of thick layer of peptidoglycan in cell wall.
- If a bacteria contain thick layer of peptidoglycan in cell wall it will retain the primary stain crystal violet (purple) and known as gram positive bacteria.
- If bacteria don't have thick layer of peptidoglycan in cell wall the stain will wash out and it will give the pink color known as gram negative bacteria.
- Peptidoglycan is glycoprotein or Glucose+Protein.
The pressure at any level in the atmosphere may be interpreted as the total weight of the above unit
The strengths of the cell model are :
easy to understand and
All cell processes are represented/shown
The weakness of cell model is :
The cell model does not represent the cell accurately (organelles are not shown )
RNAs involved in transcription are not shown in the cell model as well
The cell model is a visual representation of a biological cell as entities of their own. Some strengths of the cell model is that it is easy to understand when studied because most of the processes of cell formation are clearly shown in the model while some of the weakness that a cell model possesses are that all the organelles of the cell are not represented (this makes the cell model an inaccurate representation) also the RNA involved in transcription are not shown in the cell model.
Hence, we conclude that the weakness and strengths of the cell model are an inaccurate representation of the cell, absence of RNAs, easy to understand and proper representation of cell processes.
