Glucose does not efficiently diffuse directly through phospholipid bilayers. However, in the digestive tract, large quantities of glucose are moved from food, into the epithelial cells lining the small intestine, then out of these cells into the extracellular space and from there into the bloodstream. The relative concentrations of glucose in each of these compartments is as follows: Higher in the epithelial cell than in the food; Higher in the epithelial cell than in extracellular space; Higher in extracellular space than in bloodstream. Based on this information, predict the modes of transport used to move glucose 1) from food into the epithelial cell 2) From the epithelial cell into the extracellular space 3) From the extracellular space into the bloodstream.
A. Active transport; Simple diffusion; Simple diffusion
B. Active transport; Facilitated diffusion; Active transport
C. Active transport; Passive transport; Passive transport
D. Facilitated diffusion; Active transport; Passive transport

Will mark brainliest i only need the ! 1.use ten beads and a centromere of one color to construct the long chromosome. use ten beads and a centromere of a second color to construct the second chromosome in the long pair. make a drawing of the chromosomes in the space below. 2. for the second pair of chromosomes, use only five beads. 3. now model the replication of the chromosomes. make a drawing of your model in the space below. part b: meiosis i during meiosis i, the cell divides into two diploid daughter cells. 4. pair up the chromosomes to form tetrads. use the longer tetrad to model crossing-over. make a drawing of the tetrads in the space below. 5. line up the tetrads across the center of your “cell.” then model what happens to the chromosomes during anaphase i. 6. divide the cell into two daughter cells. use the space below to make a drawing of the result. part c: meiosis ii during meiosis ii, the daughter cells divide again. 7. line up the chromosomes at the center of the first cell, one above the other. separate the chromatids in each chromosome and move them to opposite sides of the cell. 8. repeat step 7 for the second cell. 9. divide each cell into two daughter cells. use the space below to make a drawing of the four haploid cells

What type of organism is a one-celled organism that functions as a single unit? a. bi-celled b. single-celled c. pre-celled d. multi-celled

Adrought killed all the plants in an agricultural farmland. gradually, due to wind and some birds for. nearby areas, new plants started sprouting l. what stage of succession was taking place in the farmland? a) competition b) nudation c) ecesis d) reaction e) migration
