1. The Sodium-Potassium Pump is a structure known as a cell-membrane pump that uses energy to transport Sodium and Potassium ions in and out of the cell. There are other varieties of cell membrane pump, however the sodium-potassium pump plays a vital role in maintaining a cell's homeostasis.
2. Endocytosis is a process by which cells can take in large particles and deposit them into the cell. This is accomplished by forming membrane-bound sacs that pinch off from the cell membrane.
3. Exocytosis is very similar to endoxytosis except that it deposits materials from inside the cell on the outside instead of the other way around. Vesicles are formed in the Golgi Bodies, filled with materials to be sent outside the cell, and then fuse with the cell membrane and release their contents outside of the cell.
Answer:
Cell wall exist only in plants which helps in protecting the cell from osmosis and the cell membrane is found both in plants and animals which help in protecting the cell from its genetic compoenets
Explanation:
The only one correct answer would be:
c. Yellow or red hues in the soil indicate the presence of iron or aluminum.
An organism that can make its own food is called an "Auto-troph". They maybe of two types:
1) Photo-Autotroph (Get source by sunlight)
2) Chemo-Autotroph (Get source by chemicals i.e., CH₄, NH₃ etc.)
Hope this helps!
