I think the correct answer is nitrogen. Among all the main nutrients in the biosphere, the substance that is fixed or constant inside the nodules in certain roots of plants would be nitrogen. Hope this answers the question. Have a nice day.
Answer:
A) AFP binds to ice crystals and forms a nonpolar shell that prevents covalent bonding between water molecules to form a larger crystal. By limiting crystal growth, the cell would not freeze solid
Explanation:
Water is a "polar" molecule, which means that electron density is unevenly distributed. Water has a partial negative charge, near the atom of oxygen due to the unshared pairs of electrons and partial positive charges, near the atoms of hydrogen. Because water is polar and the protein is nonpolar, their molecules are not attracted to each other this is want prevents the ice crystals from forming.
A target cell respond to a hormone because it bears receptors
The plant will still grow, false.
mark me brainiest :)
