Answer:
1) Dissolved oxygen (DO) refers to the oxygen gas that is dissolved in water. Fish absorb the DO directly from the water into their bloodstream through their gills.
2) Also called erythrocyte and RBC. Blood cells. Blood contains many types of cells: white blood cells (monocytes, lymphocytes, neutrophils, eosinophils, basophils, and macrophages), red blood cells (erythrocytes), and platelets. Blood circulates through the body in the arteries and veins.
3)Echinodermata. Hint: The largest living invertebrate belongs to the phylum Mollusca.
4) The xylem parenchyma is responsible for storing the prepared food and assists in the conduction of water. Xylem fibres are supportive in function
5) osmosis
Water entered through the root of the plant is transported to leaves and is lost in the air. The hair of the root is hypertonic to the surrounding soil or water. This causes the entry of water from the soil to the root hair through the process of osmosis.
