41 terms Tray The two new daughter cells will be haploid, but the DNA they contain is still replicated. The homologous chromosomes have separated and are ready to start the second division, but they have not yet begun the second round of division.Which stage of the cell cycle is this cell in?Telophase I Homologous pairs of chromosomes have separated into two cells. Sister chromatids in each cell have not yet lined up in the middle of the cell.Which stage of the cell cycle is this?Prophase II Which type of cell division results in sex cells?Meiosis Which characteristic describes both meiosis and mitosis? Sister chromatids separate How is DNA structured during the metaphase stage of mitosis?The centromere at the center keeps DNA lined up at the cell's equator.What is true regarding the transition from metaphase to anaphase during mitosis?Sister chromatids are aligned along the center of the cell and then pulled apart into separate chromatids.Which stage of mitosis is depicted?Prophase

Sister chromatids are being separated and moving towards opposite poles of the cell.Which stage of mitosis is this?Anaphase Chromosomes are structures that contain hereditary material that will be passed from one generation to the next.According to this information, which organic molecule must be present in chromosomes?

DNA A cell has divided its chromosomes into two new nuclei.The cytoskeleton of the cell is currently pinching the cell in the middle to form two new cells.In which stage of the cell cycle is this cell?Cytokinesis What is the function of the histones during S phase? Organizing and helping to unwind the DNA so the replication enzymes can access it What is the function of the flagellum?Locomotion and sensing What is true of a eukaryotic cell?It contains mitochondria.Some cells need to maintain a set concentration of Na + and K + ions. These cells are able to do this with the help of the Na/K pump, which transports these ions from areas of low concentration to areas of high concentration (against their concentration gradient). Na + is pumped out, and K + is pumped in.Which type of membrane transport is involved in this action?Active transport Choose the two substances that are the main components in most eukaryotic cell membranes.Lipids and proteins Which of these is an output of the light-dependent reaction of photosynthesis?

ATP Which molecule is an input to the Calvin-Benson cycle? Carbon Dioxide Which stage of cellular respiration releases carbon dioxide as a product?Krebs cycle Which stage of cellular respiration releases the most energy and, therefore, produces the most ATP molecules?Electron transport chain

In the human body, muscle fibers metabolize sugars to produce energy. Fast-twitch muscle fibers, like those used during short-term, vigorous exercise, carry out an anaerobic process that produces less energy per sugar molecule processed.Which metabolic process do fast-twitch muscle fibers carry out?Fermentation Fermentation uses sugar in the absence of which molecule?O 2 A subatomic particle has a negative charge and is found in a shell of the atom.What is this particle?An electron What is the charge of a proton?+1 A molecular bond results from an electron being transferred from one atom to another.Which type of bond holds these atoms together?Ionic Which situation describes covalent bonding?An atom shares an electron with another atom.Which substance is found in ATP?Nitrogenous base During the Calvin cycle, a sugar molecule is formed as ATP is converted into ADP and a free phosphate group.What is happening to energy in this second step of photosynthesis?Energy is being released from ATP to power the conversion of a sugar molecule.A biological polymer consists of 358 amino acids linked together covalently.What is this polymer?A protein A molecule consists of a chain of glucose monomers linked together.What is the function of this molecule within the cell?To store energy After a rainy day, a leaf has small droplets of water on its surface.Which property of water is this an example of?Cohesion

A plastic water bottle is filled with water and placed in the freezer. The next day the frozen water has expanded, causing the plastic bottle to rupture.Which characteristic of water is this an example of?Density Which of the following carries the information that determines which amino acids are used to make a protein?Messenger RNA In which eukaryotic organelle does protein assembly and modification occur?Endoplasmic reticulum A gene contains the sequence CGCATACGGTAC that results in the amino acid sequence arg-ile-arg-tyr. A mutated version of this gene has an A in place of the second C and produces the amino acid sequence arg- ile-arg-tyr.What is true regarding this mutation?The mutated gene results in the same amino acid sequence and will result in the same phenotype.Which pattern of inheritance is described when a phenotype results from the interaction of many genes?Polygenic inheritance A dog breeder mates two black Labrador retriever dogs.The breeder is surprised by the offspring produced by this crossing. In addition to offspring with beautiful black coats, there are dogs with brown, gray, and tan coats.Which form of inheritance is this an example of?Polygenic A cutting is taken from a mature hydrangea plant with blue flowers. The cutting is planted in acidic soil and produces red flowers.What caused the flower color in this hydrangea cutting to change?An interaction between the genes and the soil' A recessive mutation in the DFN3 gene causes deafness.A mother with DFN3 deafness will have sons who all have deafness.How did the sons inherit the gene for deafness?On the X chromosome from the mother What is a characteristic of DNA but not RNA?It is intertwined with histone proteins.Which item is an atom?Nitrogen
