Sand is the most permeable. PLS ANSWER MY QUESTIONS 2
Answer:
Explanation:
Hi there!
We can compare prokaryotic cells and eukaryotic cells in following points:
• The prokaryotic cells are simple and primitive type of cells whereas •Eukaryotic cells are complex and advanced cells.
•The DNA is small and circular in prokaryotic cells whereas the DNA is large and linear in eukaryotic cells.
•In prokaryotic cells 70s type of ribosome is found in cytoplasm but in Eukaryotic cells both 70s (inside cell organelles) and 80s (in cytoplasm) are found.
• In prokaryotic cells cellular respiration takes place through cell membrane but in eukaryotic cells cellular respiration takes place through mitochondria.
Hope it helps!
Answer: electron
Explanation:
An atom is made up of subatomic particles: proton, neutron and electron.
Proton and neutrons are found in the nucleus of atoms while electron is found outside the nucleus.
Thus,the only particle not found in the nucleus is electron.
If the cell membrane were not selectively permeable, then unwanted substances would transfer through instead of being blocked out. Think of it like this: you have a sifter with various sizes of spice in it. You only want the finer grains of spice in your food, so when you shake the sifter, the larger pieces of spice don't fit through the small holes that only allow fine grains. Then you are left with the small spices in your food and the large ones stuck in the sifter.
Hopefully this helps and I wasn't too confusing :)
