Hypothesis An experiment that tests only one prediction of a hypothesis at a time. Controlled experiment In a scientific experiment, a group used to evaluate possible side effects of a test involving an experimental group. Ideally, it should differ from the experimental group only with respect to the variable being studied. Control group Of a scientific experiment, the only factor that is not the same in the experimental group as it is in the control group. It is a specific aspect of an object or event that may differ over time and between subjects.

    Nonpermeable d. None of the above. A cell membrane is a thin layer of molecules that surrounds the cell. Its function is to allow certain materials to enter the cell, yet, keep harmful materials out. In order to do this, the cell controls which substances can enter the cell through the membrane. The cell membrane is selectively permeable or semipermeable , which means that certain molecules, such as oxygen and water, are permitted to enter the cell. Molecules that are not recognized as helpful are not able to pass through the membrane.
  • BIO 101 Exam 1

    Incorrect answer. Please choose another answer. A cell uses which of the following to accelerate chemical reactions enabling its metabolic machinery to operate? Centrasome c. Golgi apparatus d. Enzymes Enzymes are catalysts, chemicals that speed up chemical reactions. The conditions inside most cells do not allow reactions to proceed quickly enough to support life. For example, temperatures inside organisms are not hot enough for chemical reactions to take place quickly. Enzymes increase the rates of biological chemical reactions. Which of the following is not part of the metabolic sequence? Photosynthesis c. Hydoplasm d. Digestion Inside cells, sequences of chemical reactions take place to support life. These sequences are known as metabolic pathways.
  • Biology Multiple Choice Questions And Answers For Different Competitive Exams

    Photosynthesis, respiration, and digestion are all examples of metabolic pathways, or sequences. Photosynthesis is the metabolic pathway that produces oxygen and glucose in organisms with chlorophyll. Respiration breaks down molecules called ATP for cells to use as energy. Digestion breaks down food to be used to make energy in the form of ATP. Hydroplasm is not a known metabolic sequence. Which of the following are NOT organelles found in animal cells? Nucleus and golgi apparatus b. Cellular membrane and cytoplasm c. Mitochondria and ribosomes d. Chloroplast and central vacuole Chloroplasts and central vacuole are important organelles in plant cells. Chloroplasts contain chlorophyll and are the site of photosynthesis. Central vacuoles are used to store water in plant cells. All the other organelles listed are important to the function of animal cells and plant cells. Light initiates different types of cellular reactions. Which of the following responses to light converts the energy from light into a gain of potential energy?
  • Biology Exam I: A Quiz On Cells And The Important Macromolecules

    Phototaxis c. Photosynthesis d. All of the above Photosynthesis is the process plant cells use to convert oxygen, water and sunlight into a usable form of energy. The product of photosynthesis is glucose sugar molecules. Glucose molecules are a form of potential energy that can be broken down by an organism to produce energy in the form of ATP molecules. Gene c. Protein d. Nucleus A gene is the basic unit of heredity. Genes are made of DNA sequences and act as instructions for making proteins although not all genes make proteins. Genes are found on chromosomes. Double c. Quadruple d.
  • !!WARNING!!

    The DNA molecule looks like a twisted ladder and is referred to as a double helix. Each nucleotide contains a sugar molecule and a phosphate group, along with a nitrogen base. Genes are located within the cytoplasm of the cell. Hydrochloric acid c. Ribonucleic acid d. In the ribosome, the information coded onto messenger RNA is used to make proteins. When sexual reproduction occurs in multicellular organisms, a process takes place before cells fuse whereby a cell is left with half of its chromosomes, enabling the creation of a cell with a characteristic chromosome number.

    What is this process called? Osmosis c. Anabolism d. Differentiation During meiosis, gametes sex cells are formed by reducing the number of chromosomes found in somatic body cells by one half. This occurs so that when two gametes, one from each parent, fuse together, the embryo will contain the correct number of chromosomes. Without meiosis, offspring cells would contain double the number of chromosomes of normal adults and they would not be viable. Which of the following represents the largest group of biological classification? Kingdom c. Class d. Genus Biology uses a system of classification to group organisms together based on their characteristics.

  • Biology 1406

    Mitiosis c. Archaeans d. Organelles Organelles are specialized structures in cells that support the cellular functions. For example, mitochondria are organelles that synthesize energy; ribosomes synthesize protein; chloroplasts convert sunlight, carbon dioxide and water into oxygen and sugar. Internal complexity c. Size d. Ecological relationships Unicellular organisms are very small compared to most multicellular organisms. If they were as large as a multicellular organism, their surface area to volume ratio would be too low to support life. Staying small gives unicellular organisms a high surface area to volume ratio. Larger cells have less surface area compared to their volume. Molecules move into the cell, out of the cell and through the cell slowly through the cell membrane.

    Having a large surface area provides more space for molecules to diffuse across the cell membrane and less of a distance to travel inside the cell to supply organelles with materials needed for metabolism. How many chromosomes does an individual human person have?

    The cecum can become a vestigial structure in carnivores, since it is shorter in species B and C than in species A and D. The cecum evolved to have an important role in the digestion of protein, since it is shorter in species B and C than in species A and D. Species A is more closely related to species D than to species B, because A and D are both herbivores. Species B and C have a common ancestor, since the cecum in species B and C is approximately the same length. Answer A The data here suggest that the cecum is four to five times longer in species that consume plant matter for their diets A and D compared to those that consume at least some meat B and C.
  • Biology 141

    Of the statements listed, the only one that logically follows is A : in carnivores, the cecum becomes unnecessary, and starts to shorten. B is the opposite of what we expect; it would be logical if it played a prominent role in digesting carbohydrates. C The data on cecum length and diet are insufficient to draw conclusions about the relatedness of species, so rule out C and D. Data Question 2 The following diagram shows energy transformations within a cell.

    Two cellular organelles are represented by the letters A and B. Answer the following questions about the various processes depicted in the diagram and about the cell in which they are occurring. What form of energy is represented by E II? Radiant energy in the form of photons B. Chemical energy being stored in the bonds of glucose C. Chemical energy in the form of ATP D. Chemical energy released by glycolysis 2. If the transformation depicted in organelle B requires oxygen, what form of energy is represented by E IV? Chemical energy being stored as glycogen C. Chemical energy released by glycolysis Question 1 Answer C The reaction occurring in organelle A is photosynthesis, as indicated by the splitting of water and fixation of CO2. Question 2 Answer C The reaction occurring in organelle B is cellular respiration, as indicated by the release of energy stored in the bonds of glucose.
