Answer: The plant structures are correctly paired with its functions
Explanation: Dermal tissue: protected soft tissues of plants and controls interactions with plant surroundings(It covers the outer surface of herbaceous plants)
Parenchyma tissue: functions in storage, photosynthesis and bulk of ground and vascular tissue
Answer:
A) rely on protection and resources supplied from the maternal plant.
Explanation:

The embryo requires the nutrients for growth and absorb them from the surrounding female gametophyte structure like endosperm in the angiosperm. The embryos grow and form the sporophytic structure.

Answer: Low oxygen content.
Explanation:
There are many dangers to the survival of fish in shallow water that depend on the properties of water.
1. The oxygen content drops during the winter and also in hot weather. Fish cannot survive without enough oxygen in the water.
2. High evaporation rates can drain the pond.
3. Fortunately, water has a high thermal mass, so overheating the water to the boiling point is not an issue.
Of the three reasons given, lack of oxygen is the most critical.
