Which of the following is a correct description of metaphase during mitosis? - CORRECTANSWER
Chromosomes align along the center of the cell.
During metaphase, the chromosomes align along the center of the cell. During prophase,
chromosomes condense, and the nuclear envelope disappears during prometaphase. Anaphase
is when the chromosomes start to separate from each other. Telophase is when the
chromosomes gather on either side of the now dividing cell; it is followed by cytokinesis
Where can ribosomes be found inside of a eukaryotic cell? - CORRECTANSWER On the rough
endoplasmic reticulum and in the cytoplasm
Ribosomes can be found in two places in a eukaryotic cell: on the rough endoplasmic reticulum
(rough ER) or free floating in the cytoplasm.
What is the role of the Golgi apparatus in the eukaryotic cell? - CORRECTANSWER To package
and process materials for transport
The Golgi apparatus is responsible for the packaging and processing of materials for transport
throughout the cell or for secretion. Lysosomes digest macromolecules into their components
, using hydrolytic enzymes. The smooth ER detoxifies drugs and other harmful products. Cellular
respiration resulting in ATP production is the function of mitochondria.
Which best describes the bonds between atoms within a water molecule? - CORRECTANSWER
The bonds between atoms within the water molecule are polar covalent bonds, resulting in the
unequal sharing of electrons. Within a water molecule, the electrons in each covalent bond are
held closer to the O atom compared to the H atoms. This makes the O-end of each water
molecule have a partial negative charge, while the H ends have a partial positive charge.
Therefore, a partial positive end of one water molecule is attracted to the partial negative
charge of another water molecule, forming a hydrogen bond.
Which of the following is the MOST inclusive category in the hierarchical organizational system
for nomenclature? - CORRECTANSWER kingdom
The most inclusive category is Kingdom. The most restrictive would be Species. The mnemonic
"King Philip Came Over For Great Spaghetti," can be used to recall the order of the categories
within this organizational system from most inclusive to most restrictive.
During which phase of the eukaryotic cell cycle is DNA replicated? - CORRECTANSWER The G1, S,
and G2 phases are all phases within interphase. S phase is when DNA is replicated. The G1 and
G2 phases are periods of cell growth (G1 = first growth phase, G2 = second growth phase and
preparation for division). M phase includes mitosis and cytokinesis.
Which of the following processes begins with a diploid cell and ends in the formation of diploid
cells? - CORRECTANSWER mitosis only
Mitosis makes two identical daughter cells from an original parent cell and does not reduce
chromosome content. Meiosis is a process that begins with a diploid cell and results in the
formation of haploid cells.
Which of the following types of cell results from cell division by meiosis? - CORRECTANSWER
sperm cell
Meiosis results in the formation of gametes like sperm cells (in males) and egg cells (in females).
All other body cells, called somatic cells, undergo mitosis, not meiosis, to produce more cells.
