Which statements about Plasmodium are true?

1. Diploid Plasmodium cells enter a mosquito that bites a human infected with malaria. 2. Plasmodium cells infect two specific types of cells in humans. 3. Inside an infected mosquito, haploid gametes fuse, forming a diploid zygote that develops into an oocyst. 4. The life cycle of Plasmodium involv...

auxin experiment thanks:)

What would you expect to happen when you removed the meristem from 10 coleptiles, then placed five in water and the other five in auxin concentration of (2mg/ml)?

What would you notice about the number of cells for each section?

Re: enzyme question

Thanks blcr11, more questions 1. If you were to do an experiment to graph the effect of various substrate concentrations, would have on reaction rate and concentration of product, how would u describe the graph. (i know it go up and eventually reaches a plateau, but how would you describe this, i do...

permeable and semi permeable membranes?

permeable and semi permeable membranes? What's the difference? I've tried searching the net but theres a lot on semi permeable membranes but not that much on plain permeable membranes.
