What is the specific function of signal cells releasing chemical messages to nearby cells during early embryonic development? 1.The chemical messages will impact the cells, resulting in change to gene expression.

2. The chemical messages will facilitate the transfer of mRNA.

3. The signaling cells will initiate programmed cell death in nearby cells.

4. The signaling cells will prevent DNA mutation in nearby cells.

raits that your monster will have. the dna code for each trait is given, so you will need to go through the process of transcription and translation to determine what protein is being made and then match that with the corresponding trait. you may even include a picture of your monster if you are feeling creati

i dont know it at allnow im just getting points at this pint
