Do you have the answers?

Please help! What are the 2 ways hormones affect their target cells?

...

thanks for the thumbnail  ;D I used it to check my answers.

1. Hormones bind to high affinity receptors located on the target cells receptors, cystol, or in its nucleus and can exert a biological action.A hormone receptor complex forms and can then exert a biological action through signal-tranduction cascades and alteration of gene transcription at the target cell.

2. Peptide and catecholamine hormones are fast acting hormones that attach to a plasma-membrane receptor and cause a second-messenger cascade in the cytoplasm of the target cell.
