Suppose a similar experiment was set up to measure changes in air composition immediately before and two days after twenty potte

d plants were placed in a clear, sealed aquarium near a window. Percentages of Chemicals in Air O2 CO2 Before 20.94% 0.03% After ? ? How would the second row of values in the plant experiment most likely compare to the second row of values in the original experiment? Oxygen levels would be higher, but carbon dioxide levels would be lower. Carbon dioxide levels would be higher, but oxygen levels would be lower. Oxygen levels would be higher, but carbon dioxide levels would be the same. Carbon dioxide levels would be higher, but oxygen levels would be the same. Mark this and return Save and Exit Next

Answer:

The correct option is C: "Oxygen levels would be higher, but carbon dioxide levels would be the same".

Explanation:

The sealed aquarium is paced near a window which means they have access to sunlight, and hence, can photosynthesize. As the plants use up carbon dioxide during the day and give out oxygen during this process, they also respire during the night, a product of which is carbon dioxide. This is why the levels of carbon dioxide will remain the same and level of oxygen will rise because they are photosynthesizing for a longer period during the day than they are respiring during the night.

Hope that answers the question, have a great day!

kotykmax [81]

Answer:

basale - spinosum - granulosum - lucidum - corneum.  

Explanation:

The order of strata in the epidermis:

  • Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.
  • Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.
  • Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.
  • Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.
  • Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.
