V-m-y-f-e-n: this is the single-letter amino acid abbreviation for a peptide. what is the net charge of this peptide at ph 7.0? an enzyme called a protein tyrosine kinase can attach phosphates to the hydroxyl groups of tyrosine (y). what is the net charge of the peptide at ph 7.0 after it has been phosphorylated by a tyrosine kinase? what is the likely source of phosphate used by the kinase for this reaction

Water changes bacteria in the soil converts this nutrient into a usable form. plants take up the usable nutrient through the soil and assimilate it into proteins, making it part of the plant. an animal eats the plants, and the nutrient becomes part of the animal. when the animal dies, it decomposes, returning the nutrient back to the soil. which cycle is being described? water cycle carbon cycle nitrogen cycle phosphorous cycle
