Answer the following question given this paragraph: The Major Divisions of Land Plants Land plants are classified into two major groups according to the absence or presence of vascular tissue, as detailed in Figure 14.8. Plants that lack vascular tissue formed of specialized cells for the transport of water and nutrients are referred to as nonvascular plants. The bryophytes, liverworts, mosses, and hornworts are seedless and nonvascular, and likely appeared early in land plant evolution. Vascular plants developed a network of cells that conduct water and solutes through the plant body. The first vascular plants appeared in the late Ordovician (461444 million years ago) and were probably similar to lycophytes, which include club mosses (not to be confused with the mosses) and the pterophytes (ferns, horsetails, and whisk ferns). Lycophytes and pterophytes are referred to as seedless vascular plants. They do not produce seeds, which are embryos with their stored food reserves protected by a hard casing. The seed plants form the largest group of all existing plants and, hence, dominate the landscape. Seed plants include gymnosperms, most notably conifers, which produce "naked. Q: Land plants are classified into two major groups according to the absence or presence of what tissue? Choices: - disease - root - bacterial - vascular A:
vascular
Q: Answer the following question given this paragraph: Intrusive igneous rocks cool from magma slowly in the crust. They have large crystals. Q: Intrusive igneous rocks cool from magma slowly in the crust and have large what? Choices: - pores - atoms - coal deposits - crystals A:
A: crystals
Question: Answer the following question given this paragraph: Concentration is the number of particles of a substance in a given volume. When the concentration of reactants is higher, the reaction rate is faster. At higher concentrations, particles of reactants are crowded closer together, so they are more likely to collide and react. Did you ever see a sign like the one in the Figure below ? You might see it where someone is using a tank of pure oxygen for a breathing problem. Combustion, or burning, is a chemical reaction in which oxygen is a reactant. A greater concentration of oxygen in the air makes combustion more rapid if a fire starts burning. Q: What kind of reaction do you see when the concentration of reactants is higher? Choices: - regular reaction rate - slow reaction rate - constant reaction rate - faster reaction rate A:
Answer: faster reaction rate

**Answer**
the plasma membrane

Answer the following question given this paragraph: Proteins play many important roles in living things. Some proteins help cells keep their shape, and some make up muscle tissues. Many proteins speed up chemical reactions in cells. Other proteins are antibodies, which bind to foreign substances such as bacteria and target them for destruction. Still other proteins carry messages or materials. For example, human red blood cells contain a protein called hemoglobin, which binds with oxygen. Hemoglobin allows the blood to carry oxygen from the lungs to cells throughout the body. A model of the hemoglobin molecule is shown in Figure below . Q: What type of proteins bind to foreign substances and attempt destruction? Choices: - membranes - ribosomes - antigens - antibodies A:
(Answer)
antibodies
