1: Why does Jeroen Ritsema think it’s too early to conclude that the pushing argument explains the Atlantic’s expansion? What would satisfy him that the pushing scenario might be the real answer? 2: What are some reasons why scientists might care about the movements of tectonic plates?

3: What is one practical reason why people might care about these movements? ( hint: For whom are accurate identification of positions important?)

the answer is a or when it says crossing over

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
