Q: What do many mollusks secrete for their protection? Read this paragraph and choose the correct option from the provided answers: 15.4 Mollusks and Annelids The phylum Mollusca is a large, mainly marine group of invertebrates. Mollusks show a variety of morphologies. Many mollusks secrete a calcareous shell for protection, but in other species, the shell is reduced or absent. Mollusks are protostomes. The dorsal epidermis in mollusks is modified to form the mantle, which encloses the mantle cavity and visceral organs. This cavity is distinct from the coelomic cavity, which the adult animal retains, surrounding the heart. Respiration is facilitated by gills known as ctenidia. A chitinous scraper called the radula is present in most mollusks. Mollusks are mostly dioecious and are divided into seven classes. The phylum Annelida includes worm-like, segmented animals. Segmentation is both external and internal, which is called metamerism. Annelids are protostomes. The presence of chitinous hairs called chaetae is characteristic of most members. These animals have well-developed nervous and digestive systems. Polychaete annelids have parapodia that participate in locomotion and respiration. Suckers are seen in the order Hirudinea. Breeding systems include separate sexes and hermaphroditism. Choices: - mucus - sedimentation shell - microscopic shell - calcareous shell A:
calcareous shell

Q: What must be present on a plant where ladybugs will lay their eggs? Read this paragraph and choose the correct option from the provided answers: Ladybugs, also known as ladybird beetles, have a life cycle of four to six weeks. In one year as many as six generations of ladybird beetles may hatch. In the spring, each adult female lays up to 300 eggs in small clusters on plants where aphids are present. After a week the wingless larvae hatch. Both the ladybird beetle larvae and adults are active predators, eating only aphids, scales, mites and other plant-eating insects. The ladybugs live on the vegetation where their prey is found, which includes roses, oleander, milkweed and broccoli. Adult ladybugs don't taste very good. A bird careless enough to try to eat one will not swallow it. Choices: - dew drops - mites - butterflies - aphids A:
**Answer**
aphids

Read this paragraph and choose the correct option from the provided answers: The diffusion of water across a membrane because of a difference in concentration is called osmosis. Choices: - cell transportation - hemostasis - electrolysis - osmosis A:
A: osmosis
