Answer:
C. a decrease in phospholipid fatty acid side chain length and a decrease in side chain saturation
Explanation:
Temperature is a factor that has a huge impact on cell membrane structure, more precisely its fluidity. So, for example, if temperature increases, the cell membrane becomes more fluid because the fatty acid tails of the phospholipids become less rigid.
Answer:
d. Autoradiographies
Explanation:
Based on the information provided within the question it can be said that the technique that is mainly used for this are Autoradiographies. This is a technique that is mostly used for X- ray film to visualize molecules or fragments of molecules that have been radioactively but are also used for analyzing the length and number of DNA fragments using a special method called gel electrophoresis which is then used to compare the various DNA samples.
