- The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others.
- <em><u>Small molecules that are non-polar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.</u></em>
- Charged ions such as N+ and K+ Cannot permeate the cell membrane for the since uncharged molecules repel uncharged molecules present in the membrane structure.
Similarities: Mitosis and meiosis both involve cell replication. They both involve prophase, metaphase, anaphase, and telophase.
Differences: Meiosis creates gametes while mitosis creates somatic cells. Mitosis creates two daughter cells, while meiosis creates four sperm cells in men and one egg cell and three polar bodies in women. Mitosis involves one round of cell division, while meiosis involves two. Mitosis creates cells that have the same number of chromosomes as the original cell, while meiosis creates cells that have half the number of chromosomes as the original cell.
Hope that helped you.
P.S. There are more similarities and differences, challenge yourself and see if you can find them! Good luck.
Answer:
Biology is not a hard class however it does require memorization and comprehension of certain topics. I recommend that you read over the chapters and make flashcards and test yourself. You can also ask your teacher for help. There are many videos available that do a great job at explaining each topic in biology. In addition, there are various websites that can also provide information. You should make study groups with your classmates as it is a more fun and effective way of studying.
