During nitrogen fixation, bacteria breaks nitrogen gasses down into a usable form for plants.
This model suggests that the cell membrane is a dynamic structure, because the proteins and phospholipids move laterally within the lipid bilayer ( so it is more of a fluid than solid)
(Mark me the brainliest if this has helped)
Answer:
This is called a glycoprotein.
Crossing over at prophase I results in the linked genes (those on the same chromosome) becoming unlinked and separated. Prophase I is this first stage of meiosis, the chromosomes condense, form tetrads, and exchange DNA. The nucleolus and nuclear envelope disappear.
A major problem in sending space probes to Jupiter is that the planet has no solid surface on which to land, as there is a smooth transition between the planet's atmosphere and its fluid interior. Any probes descending into the atmosphere are eventually crushed by the immense pressures within Jupiter
