A single na+/k+ atpase pump is present in the plasma membrane of an artificial cell with an initial cellular environment of 1000 sodium ions and 1000 molecules of atp inside the cell, 1000 potassium ions outside the cell, and a net charge differential across the plasma membrane of 0. Assuming the only changes in the cellular environment are a result of the pump's actions, what would be the number of na+, k+ and atp molecules inside the cell after 100 cycles of the pump and what would be the net charge differential (inside-outside) across the plasma membrane?.

Summarize the work of famous environmental scientists of the past.

Tortoise shells and snail shells are similar in function: they protect the organism from predators. based on a comparison of the organisms in the images, what can you conclude? 1. tortoises and snails have homologous organs, and they’re evolutionarily related. 2. tortoises and snails have homologous organs, and they belong to same species. 3. tortoises and snails have analogous organs, and they belong to the same species. 4. tortoises and snails have analogous organs, and they don’t belong to the same species. 5. tortoises and snails have analogous organs, and they aren’t evolutionarily related.
