Biology Midterm Review. 1. Biology Midterm Review.

You do not have to write the questions down as I will post this on www.slideshare.com. You should write down the number of the question and try to answer each question. The correct answer will be provided. Molecules of inside cells encode information to direct their growth and development. DNA. 2 The study of the interactions of living organisms with one another and with the nonliving part of their environment is called. ecology.

Honors Biology – Midterm Exam 2015-2016. Midterm Review. Standalone review guide. Using the scenario below answer questions 1-9.

3 All cells have the same basic. structure. 4 is the sum of all chemical reactions carried out in an organism. Metabolism. 5 To function properly, all living things maintain a constant internal environment through the process of. homeostasis. 6 Genetic engineers are transplanting plant into other plants to create crops that are resistant to frost damage.

genes or DNA. 7 Frogs, toads, and salamanders are all examples of. amphibians. 8 An educated guess, or , may be tested by experimentation. hypothesis. 9 In a controlled experiment, the group is the group that receives some type of experimental treatment.

experimental or the manipulated. 10 A unifying explanation for a broad range of observations is a(n).

theory. 11 A(n) is a group of atoms held together by covalent bonds. molecule. 12 The attraction between oppositely charged ions results in the formation of a(n). ionic bond.

13 Substances with a pH lower than 7 are. acidic. 14 Long chains of nucleotides are called. nucleic acids. 15 The starting materials for chemical reactions are called , while the new substances that are formed are called. reactants, products.

16 The energy needed to start a chemical reaction is called. activation energy. 17 The portion of an enzyme molecule into which a specific substrate can fit is called the. active site. 18 Scientists use units when taking measurements. metric or SI. 19 is a measure of the clarity of an image.

Resolution. 20 While a light microscope uses light to visualize a specimen, electron microscopes use an beam and a vacuum chamber. electron. 21 The basic unit of structure and function in an organism is the. cell.

22 Modern prokaryotes are generally known as. bacteria. 23 Scientists think that cells evolved about 1.5 billion years ago. eukaryotic.

24 A phospholipid is a molecule with a(n) head. polar.

25 Rough endoplasmic reticulum has embedded on its surface. ribosomes. 26 The ultimate source of energy for all life on Earth is the.

Sun. 27 Organisms that harvest energy from sunlight or inorganic substances in order to make food molecules are called. autotrophs. 28 When a phosphate group is removed from an ATP molecule, energy is. released.

29 The electron transport chain produces molecules that temporarily store in the cell. energy.

30 The transfer of carbon dioxide to organic compounds is called carbon dioxide. fixation. 31 Electrons that provide the energy for the production of most of a cell’s ATP are carried to the electron transport chain by and molecules. NADH, FADH2. 32 Hydrogen ions combine with electrons and oxygen forming at the end of the electron transport chain. water.

33 is the process by which bacteria split asexually into two identical organisms. Binary fission. 34 The DNA in eukaryotic cells is packaged into structures that are called. chromosomes. 35 In humans, the genotype XX results in a. female. 36 Somatic cells containing two sets of 23 chromosomes are always.

diploid. 37 The sequence of events that occurs in a cell from one mitotic division to the next is called the. cell cycle. 38 The cell cycle is controlled in eukaryotes at three principal.

checkpoints. 39 “ Cables” made of microtubules that extend from the poles of a cell to the centromeres during cell division are called. spindle fibers. 40 Chromosomes coil up and become visible during.

prophase. 41 After a new nuclear membrane forms during telophase of mitosis or meiosis, the divides, resulting in two cells.

cytoplasm. 42 The four haploid cells formed in the male at the end of meiosis II develop a tail and are called. sperm. 43 A spore is a haploid reproductive cell produced by.

meiosis. 44 The diploid phase in the life cycle of plants is called the. sporophyte.

45 The patterns that Mendel discovered form the basis of , the branch of biology that deals with heredity. genetics.

46 A(n) cross is a cross that involves one pair of contrasting traits. monohybrid. 47 Different forms of a particular gene are called. alleles. 48 The external appearance of an organism is its. phenotype. 49 In pea plants, tallness ( T ) is dominant to shortness ( t ).

Crosses between plants with these traits can be analyzed using a Punnett square similar to the one shown below. Refer to the illustration on the board. Box 2 and box in the Punnett square represent plants that would be heterozygous for the trait for tallness. 3.

50 Identifying patterns of inheritance within a family over several generations is possible by studying a diagram called a(n). pedigree. 51 A genetic disorder resulting in defective blood clotting is. hemophilia. 52 Viruses that infect bacteria are called. bacteriophages. 53 Due to the strict pairing of nitrogen bases in DNA molecules, the two strands are said to be to each other.

complementary. 54 The circular DNA molecules in prokaryotes usually contain replication forks during replication, while linear eukaryotic DNA contains many more.

two. 55 The process by which a foreign gene is replicated by insertion into a bacterium is called. gene cloning. 56 A large number of genetically identical cells grown from a single cell are called. clones.

57 Transferring normal human genes into human cells that lack them is called. gene therapy. 58 Crop plants have recently been developed that are resistant to the chemical , a powerful weedkiller. glyphosate. 59 Biologists have introduced extra copies of the genes that code for into the chromosomes of cows and hogs to create leaner, faster-growing animals.

growth hormone. 60 The study of radioactive decay in rocks indicates that the Earth is about years old. 4.5 billion.

61 By determining the number of half-lives that have passed since the formation of a rock containing radioisotopes and their stable daughter elements, scientists are able to determine the approximate of the rock. age. 62 Cyanobacteria produced the that is now present in our atmosphere.

oxygen. 63 Both mitochondria and chloroplasts have their own. DNA.

64 Having more than one cell is known as. multicellularity.

65 The three atoms shown in the diagram make up a molecule of. ozone. 66 Flying insects carry from a flowering plant to other flowers of the same species.

pollen. 67 Insects developed important relationships with plants. flowering. 68 The first vertebrates on land were.
