Answer the following question given this paragraph: Try your hand at diagnosing an allergic reaction by selecting one of the interactive case studies (http://openstaxcollege. org/l/world_allergy) at the World Allergy Organization website. Autoimmunity Autoimmunity is a type of hypersensitivity to self-antigens that affects approximately five percent of the population. Most types of autoimmunity involve the humoral immune response. An antibody that inappropriately marks self-components as foreign is termed an autoantibody. In patients with myasthenia gravis, an autoimmune disease, muscle-cell receptors that induce contraction in response to acetylcholine are targeted by antibodies. The result is muscle weakness that may include. Q: What is the term for an antibody that inappropriately marks self-components as foreign? Choices: - rogue antibody - compromised antibody - autoimmune antibody - autoantibody A:
autoantibody

Answer the following question given this paragraph: Saturated hydrocarbons contain only single bonds between carbon atoms. They are also called alkanes. They may form straight-chain, branched-chain, or cyclic molecules. Compounds with the same number of atoms but different shapes are called isomers. Q: What is another word for saturated hydrocarbons? Choices: - catalysts - enzymes - aldehydes - alkanes A:
(Answer)
alkanes
Ques: Answer the following question given this paragraph: As you learned in Chapter 1 "Introduction to Chemistry", the mass number is the sum of the numbers of protons and neutrons present in the nucleus of an atom. The mass number is an integer that is approximately equal to the numerical value of the atomic mass. Although the mass number is unitless, it is assigned units called atomic mass. Q: What number is the sum of the numbers of protons and neutrons present in the nucleus of an atom? Choices: - nuclear number - combined number - mass total - mass number A:
Ans: mass number
(Q).
Answer the following question given this paragraph: Different seafloor magnetic stripes equal different ages. By using geologic dating techniques, scientists could figure out what these ages are. They found that the youngest rocks on the seafloor were at the mid-ocean ridges. The rocks get older with distance from the ridge crest. Scientists were surprised to find that the oldest seafloor is less than 180 million years old. This may seem old, but the oldest continental crust is around 4 billion years old. Q: Geologists found that the youngest rocks on the seafloor were where? Choices: - early - ocean ridges - late - ocean ridges - seabed floor - mid - ocean ridges A:
(A).
mid - ocean ridges
Ques:Answer the following question given this paragraph: Q: Nucleic acids are polymers made of monomers called what? Choices: - loops - carotenoids - peptides - nucleotides A:

Ans:nucleotides
Answer the following question given this paragraph: Basic Techniques in Protein Analysis The ultimate goal of proteomics is to identify or compare the proteins expressed from a given genome under specific conditions, study the interactions between the proteins, and use the information to predict cell behavior or develop drug targets. Just as the genome is analyzed using the basic technique of DNA sequencing, proteomics requires techniques for protein analysis. The basic technique for protein analysis, analogous to DNA sequencing, is mass spectrometry. Mass spectrometry is used to identify and determine the characteristics of a molecule. Advances in spectrometry have allowed researchers to analyze very small samples of protein. X-ray crystallography, for example, enables scientists to determine the three-dimensional structure of a protein crystal at atomic resolution. Another protein imaging technique, nuclear magnetic resonance (NMR), uses the magnetic properties of atoms to determine the three-dimensional structure of proteins in aqueous solution. Protein microarrays have also been used to study interactions between proteins. Large-scale adaptations of the basic two-hybrid screen (Figure 17.17) have provided the basis for protein microarrays. Computer software is used to analyze the vast amount of data generated for proteomic analysis. Genomic- and proteomic-scale analyses are part of systems biology. Systems biology is the study of whole biological systems (genomes and proteomes) based on interactions within the system. The European Bioinformatics Institute and the Human Proteome Organization (HUPO) are developing and establishing effective tools to sort through the enormous pile of systems biology data. Because proteins are the direct products of genes and reflect activity at the genomic level, it is natural to use proteomes to compare the protein profiles of different cells to identify proteins and genes involved in disease processes. Most pharmaceutical drug trials target proteins. Information obtained from proteomics is being used to identify novel drugs...
