SB1a: A cell membrane has a double layer of molecules. These molecules are made up of a phosphorous-containing "head" and two long, fatty acid "tails."
Which of the following best explains why the molecules are classified as lipids?
They contain phosphorous
They form a double layer
They are made up of fatty acids.
They are found in the cell membrane.
SB1a: The diagram below shows a female gamete.
Which structure stores most of the genetic information?
Cytoplasm
Plasma Membrane
Nucleus
Mitochondria
SB1a: Eukaryotic cells are different from prokaryotic cells because eukaryotic cells
are much smaller
have permeable membranes
have a higher rate of reproduction
have nuclei
SB1b: The genome of a goldfish contains 96 chromosomes. How many chromosomes will each daughter cell have after mitosis of a goldfish cell is complete?
24
48
96
192
SB1b: A scientist conducted a study of an organism and found that its body cells contained 40 chromosomes. These cells were cultured in the laboratory, and cell division was observed. What difference, if any, would the scientist expect to observe between body cell division and sex cell division in the organism?
Body cells divide by mitosis, and sex cells divide by meiosis
Body cells divide by meiosis, and sex cells divide by mitosis
There is no difference: body cells and sex cells both divide by mitosis
There is not difference: body cells and sex cells both divide by meiosis
SB1b: What is one advantage of sexual reproduction?
The offspring are identical to the parents
The offspring are resistant to all viruses.
The offspring are born live, rather than from eggs.
The offspring inherit a wider variety of genetic information
SB3c: Roses produced asexually from cuttings are genetically identical to the parent. Roses grown from sexually produced seeds may look different from either parent.
Which statement is best supported by this information?
Sexually produced plants are a new species.
Sexual reproduction produces more variation in plants.
Asexually produced plants are larger than sexually produced plants.
Asexual reproduction helps plants adapt to different environments.
SB3c: Which process allows for an organism to increase the number of body cells during development and growth?
Budding
Conjugation
Meiosis
Mitosis
SB4c: Which of the following is not able to reproduce outside a host cell?
Bacteria
E.Coli
Virus
Eukaryote
