Answer:
Calcium is taken up by roots from the soil solution and delivered to the shoot via the xylem. It may traverse the root either through the cytoplasm of cells linked by plasmodesmata (the symplast) or through the spaces between cells (the apoplast).
The potential concerns with genetic engineering can be some ethical concerns, decrease genetic diversity, and not understanding the full effects of altering DNA. The correct options are 1, 3, and 4.
<h3>What is genetic engineering?</h3>
Genetic engineering (also known as genetic modification) is a process that uses laboratory-based technologies to alter an organism's DNA makeup.
This could entail changing a single base pair (A-T or C-G), deleting a region of DNA, or inserting a new segment of DNA.
The potential concerns with genetic engineering can be some ethical concerns, decrease genetic diversity, and not understanding the full effects of altering DNA.
Thus, the correct options are 1, 3, and 4.
