Answer the following question given this paragraph: Aquatic arthropods use gills to exchange gases. These gills have a large surface area in contact with the water, so they can absorb more oxygen. Q: What do aquatic arthropods use to exchange gases? Choices: - lungs - pores - diaphragm - gills A:
gills
Answer the following question given this paragraph: The digestive system consists of organs that break down food and absorb nutrients such as glucose. Organs of the digestive system are shown in Figure below . Most of the organs make up the gastrointestinal tract. The rest of the organs are called accessory organs. Q: Which system consists of organs that break down food and absorb nutrients such as glucose? Choices: - circulatory system - excretory system - urinary system - digestive system A:
digestive system
Q: Answer the following question given this paragraph: Interspecific competition often leads to extinction. The species that is less well adapted may get fewer of the resources that both species need. As a result, members of that species are less likely to survive, and the species may go extinct. Q: What kind of competition often leads to extinction because the species that is less well adapted gets fewer of the resources that both species need? Choices: - intraspecific competition - parasitism - mutualism - interspecific competition A:
A: interspecific competition

Answer the following question given this paragraph: 25.4 Seedless Vascular Plants Vascular systems consist of xylem tissue, which transports water and minerals, and phloem tissue, which transports sugars and proteins. With the development of the vascular system, there appeared leaves to act as large photosynthetic organs, and roots to access water from the ground. Small uncomplicated leaves are microphylls. Large leaves with vein patterns are megaphylls. Modified leaves that bear sporangia are sporophylls. Some sporophylls are arranged in cone structures called strobili. Q: What type of tissue transports water and minerals in a vascular plant? Choices: - collagen - capillaries - chlorophyll - xylem A:
**Answer**
xylem

Answer the following question given this paragraph: The strength of an acid depends on how many hydrogen ions it produces when it dissolves in water. A stronger acid produces more hydrogen ions than a weaker acid. For example, sulfuric acid (H 2 SO 4 ), which is found in car batteries, is a strong acid because nearly all of it breaks down into ions when it dissolves in water. On the other hand, acetic acid (CH 3 CO 2 H), which is the acid in vinegar, is a weak acid because less than 1 percent of it breaks down into ions in water. Q: The strength of an acid depends on how many of which ions it produces when it dissolves in water? Choices: - silicon - carbon - helium - hydrogen A:
(Answer)
hydrogen
