Answer:
The rise in mass noted is likely attributed to the osmosis of water molecules from an unidentified solution A.
Explanation:
Osmosis can be understood as the movement of water molecules from a region with a higher concentration to one with a lower concentration along the concentration gradient. Consequently, this process occurs without the need for energy.
Since we noticed an increase in the mass of the sweet potato, we can deduce that this mass gain resulted from osmosis, considering that the water concentration outside the cell was greater than that inside the cell.
Choanoflagellates and sponges are sister groups Explanation: Choanoflagellates are tiny unicellular organisms in the kingdom Protista, morphologically akin to the choanocyte cells of sponges, featuring a central flagellum encircled by a collar of microvilli. Consequently, choanoflagellates are often regarded as the closest living relatives of primitive metazoans, thus classifying them as sister groups to sponges. Recent molecular phylogenetic and genomic studies have backed this idea.
The cells capable of dividing into neurons or glia, but which are not classified as either, are termed NEURAL STEM CELLS.
