The warmth and redness of the surrounding area of the cut is due to the immune system.
Blood carries white blood cells, which attacks pathogens (Cause of infection)
The surface become red and warm as that is a conjugating area of blood.
Parenchyma is the answer because whereas the other two, xylem and phloem are vascular tissues, parenchyma is a packing tissue.
The answer is D, metaphase
Answer:
on a tyrosine residue
bind to insulin
Explanation:
The insulin receptor substrate-1 (IRS1) is a signaling protein that can be phosphorylated on multiple tyrosine and serine/threonine residues. IRS1 contains several conserved domains including a pleckstrin (PH) domain and a PTB domain involved in protein phosphorylation and ligand binding. In the first place, IRS1 is phosphorylated on a tyrosine residue, and then IRS1 binds to insulin or the insulin-like growth factor-1 (IGF-1), thereby activating transduction pathways such as, for example, MAPK/ERK. Moreover, RS1 is also phosphorylated on serine residues, thereby triggering opposite effects in insulin-associated signaling.
