There is a layer of tissue called the mantle between the shell and the body. Most mollusks have tentacles for feeding and sensing, and many have a muscular foot. Mollusks also have a coelom, a complete digestive system, and specialized organs for excretion. The majority of mollusks live in the ocean. Different classes of mollusks have different ways of obtaining food. Q: Snails, scallops, and squids are what type of invertebrate? Choices: - crustacean - algae - arthropod - mollusk A:

Answer the following question given this paragraph: In addition to the amount of salts, other conditions in ocean water vary from place to place. One is the amount of nutrients in the water. Another is the amount of sunlight that reaches the water. These conditions depend mainly on two factors: distance from shore and depth of water. Oceans are divided into zones ( Figure below ) based on these two factors. The ocean floor makes up another zone. Q: Oceans are divided into zones bases on distance from shore and what other factor? Choices: - temperature - salinity - animal species - water depth A:

Answer the following question given this paragraph: The nuclear envelope is a double membrane of the nucleus that encloses the genetic material. It separates the contents of the nucleus from the cytoplasm. The nuclear envelope is made of two lipid bilayers, an inner membrane and an outer membrane. The outer membrane is continuous with the rough endoplasmic reticulum. Many tiny holes called nuclear pores are found in the nuclear envelope. These nuclear pores help to regulate the exchange of materials (such as RNA and proteins) between the nucleus and the cytoplasm. Q: What is a double membrane of the nucleus that encloses the genetic material? Choices: - cell wall - cell membrane - nuclear wall - nuclear enevelope A:
nuclear enevelope
