Correct (Verified Solutions)
Which type of cell division results in sex cells? - ANSWER👀Meiosis
Which characteristic describes both meiosis and mitosis? - ANSWER👀Sister chromatids
separate
How is DNA structured during the metaphase stage of mitosis? - ANSWER👀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? -
ANSWER👀Sister chromatids are aligned along the center of the cell and then pulled apart
into separate chromatids.
Sister chromatids are being separated and moving towards opposite poles of the cell. Which
stage of mitosis is this? - ANSWER👀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? - ANSWER👀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? - ANSWER👀Cytokinesis
What is the function of the histones during S phase? - ANSWER👀Organizing and helping
to unwind the DNA so the replication enzymes can access it
What is the function of the flagellum? - ANSWER👀Locomotion and sensing
What is true of a eukaryotic cell? - ANSWER👀It contains a mitochondrion.
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? - ANSWER👀Active transport
Choose the two substances that are the main components in most eukaryotic cell
membranes. - ANSWER👀Lipids and proteins
A fly is heterozygous for wing length, carrying one allele for the dominant long-winged
appearance and one allele for the recessive short-winged appearance.Which percentage of
the fly's gametes will carry the short-winged allele? - ANSWER👀50%
Black (B) is the dominant color, and red (b) is the recessive color in a species of beetle. Two
beetles that are both Bb are crossed. What percentage of the offspring will be red? -
