Answer:
The structure of each cell type's wall.
Explanation:
The basis of Gram stain is differentiating cells in two different categories depending on the composition of the cell wall. Gram positives fixate a KI and Crystal Violeta complex in their peptidoglycan wall, but otherwise, gram negatives don't have a thick layer of this, and therefore, when the wash process happens it takes away all the pigments leaving the cells blank for the last pigment (pink).
A MYSTERIOUS ailment has been devastating the much studied lions of the Serengeti National Park in Tanzania, and scientists said yesterday that it had been identified as canine distemper, a viral disease that causes severe neurological symptoms and death.
Answer:
Explanation:
The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.
Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.
So, salt, water, and fats do not contribute to the movement of larger molecules, but <u>channel or transport proteins do and choice A is correct. </u>
