Humans start off as a single fertilized cell. How does that one cell create multiple organs and organ systems to form a single human? Cells are not differentiated and there are not special tissue types. All cells are the same with identical DNA and proteins navigate their way to the appropriate organs.

As cells replicate, the new cells only replicate small sections of DNA that they will need to be specialized as a new emerging tissue.

As cells replicate, new cells appear for specialized tissues

As the organism grows, different genes are turned on or off through cell differentiation

I already tried the second one and it was wrong

Did you know that a single bee would have to go to over 2 million flowers to make a single pound of honey?

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
