Ques: Answer the following question given this paragraph: The DNA of a chromosome is encoded with genetic instructions for making proteins. These instructions are organized into units called genes . Most genes contain the instructions for a single protein. There may be hundreds or even thousands of genes on a single chromosome. Q: What are the organized instructions within dna for making proteins called? Choices: - clones - genomes - replicants - genes A:
Ans: genes

Ques: Answer the following question given this paragraph: in color. Golden algae are found in both freshwater and marine environments, where they form a major part of the plankton community. The brown algae are primarily marine, multicellular organisms that are known colloquially as seaweeds. Giant kelps are a type of brown algae. Some brown algae have evolved specialized tissues that resemble terrestrial plants, with root-like holdfasts, stem-like stipes, and leaf-like blades that are capable of photosynthesis. The stipes of giant kelps are enormous, extending in some cases for 60 meters. A variety of algal life cycles exists, but the most complex is alternation of generations, in which both haploid and diploid stages involve multicellularity. Compare this life cycle to that of humans, for instance. Haploid gametes produced by meiosis (sperm and egg) combine in fertilization to generate a diploid zygote that undergoes many rounds of mitosis to produce a multicellular embryo and then a fetus. However, the individual sperm and egg themselves never become multicellular beings. Terrestrial plants also have evolved alternation of generations. In the brown algae genus Laminaria, haploid spores develop into multicellular gametophytes, which produce haploid gametes that combine to produce diploid organisms that then become multicellular organisms with a different structure from the haploid form (Figure 23.19). Certain other organisms perform alternation of generations in which both the haploid and diploid forms look the same. Q: Some marine algae have evolved special structures capable of what plant process? Choices: - pollination - respiration - seed germination - photosynthesis A:
Ans: photosynthesis

Ques: Answer the following question given this paragraph: If more NH 3 were added, the reverse reaction would be favored. This "favoring" of a reaction means temporarily speeding up the reaction in that direction until equilibrium is reestablished. Recall that once equilibrium is reestablished, the rates of the forward and reverse reactions are again equal. The addition of NH 3 would result in increased formation of the reactants, N 2 and H 2 . Q: What's it called when the reaction is sped up until equilibrium is established? Choices: - limiting - pushing - division - favoring A:
Ans: favoring

Ques: Answer the following question given this paragraph: Cartilaginous Joints Cartilaginous joints are joints in which the bones are connected by cartilage. There are two types of cartilaginous joints: synchondroses and symphyses. In a synchondrosis, the bones are joined by hyaline cartilage. Synchondroses are found in the epiphyseal plates of growing bones in children. In symphyses, hyaline cartilage covers the end of the bone but the connection between bones occurs through fibrocartilage. Symphyses are found at the joints between vertebrae. Either type of cartilaginous joint allows for very little movement. Synovial Joints Synovial joints are the only joints that have a space between the adjoining bones (Figure 38.25). This space is referred to as the synovial (or joint) cavity and is filled with synovial fluid. Synovial fluid lubricates the joint, reducing friction between the bones and allowing for greater movement. The ends of the bones are covered with articular cartilage, a hyaline cartilage,. Q: What term is used to describe joints in which the bones are connected by cartilage? Choices: - capillaries joints - blob joints - spinal joins - cartilaginous joints A:
Ans:
cartilaginous joints
