I think the answer to this question is hypertonic to hypotonic as diffusion is the movement of water from a high to low concentration and hypertonic contains a high concentration of solutes and hypotonic contains a low concentration of solutes (the are opposites). Hope this makes sense
Answer:
1. Apoplastic
2. Symplastic
3. Symplastic
4. Apoplastic
Explanation:
The interconnected porous cell walls of plant cells make apoplast along which water is allowed to move freely. Symplast refers to the path made up of interconnected cytoplasm of many plant cells connected by plasmodesmata. Therefore, water and dissolved minerals enter the root cortex from the epidermis in the solution can move through symplast and apoplast till endodermis.
Water and dissolved minerals present in the cytoplasm of cortical cells move from one cell to next via plasmodesmata (the symplast) while the ones present in their cell walls and intercellular space move through apoplast. The presence of casparian strips in the endodermal cell wall does not allow the movement of water and minerals through the apoplast.
I’m pretty sure it’s b only a guess
Explanation:
Index fossils are fossils type fossils that are used to identify stratigraphic records and their positions. They are vey key in determining relative ages of rock sequences.
- These fossils have a short vertical stratigraphic range.
- Index fossils have short evolutionary history.
- They are widely distributed in nature.
- Examples of index fossils are trilobites and ammonites.
