Answer:
1) Plant cells have large sized vacoles than animal cells.
2) Plant cells have plastids and animal cell do not.
3) Plant cells have chloroplasts and animal cell don't.
4) Plant cells have cell walls and animals cells don't.
Explanation:
Answer: B. dissection
Autopsy or postmortem is a medical examination of human body that is performed to know the cause, manner and duration since death. The autopsy involves complete examination of the body. The external examination gives indication of situation of the body : number of injury, color changes due to the affect of poisons. Internal examination gives indication of condition of organ in the body of deceased. For a complete internal examination dissection is required. Autopsy is complete when all four cavities like cranial, thoracic, abdominal and pelvic are open through dissection, which allows the assessment of organs present in these cavities. Opening of the intestinal cavity will give a way to assess the intestine, which can be dissected to know the contents present in it.
The structure that surround and protect the cell depends on the cell type: for plants cells it would be a cell wall whereas for an animal cell it would be the cell membrane :)
During translation to RNA, the nitrogen bases on the DNA molecule are translated to complementary RNA bases. Afterwards, these bases are again used to form amino acids.
Three bases make up a codon, which codes for a specific amino acid. If a base is changed, the codon will become changed. This will result in a different amino acid being produced in and the primary structure of the polypeptide will be altered.
Answer:
B) a higher protein to lipid ratio.
Explanation:
The cell membrane of eukaryotes is known to be a phospholipid bilayer with embedded proteins. This implies that the first tube will contain a higher amount of lipids.
The membrane of the mitochondria is slightly different from the cell membrane in which its protein to lipid ratio is higher, containing a large number of integral proteins.
