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!
Answer: The correct answer for the blank is -
1.) A. Phenotype
B. Genotype
Phenotype corresponds to the physical appearance of a particular characteristic or morphological form in an individual.
Example - Hair color, plant height, skin color.
On the other hand, genotype corresponds to the genetic makeup of an individual. It is depicted by the gene that is present in the individual organism. Example- Genotype for dwarf height in pea plant is 'tt', which carries both recessive gene variants.
Thus, we can physically see the phenotype of a trait, but not the genotype.
The correct answer is: The trench is formed by a subduction zone which has also created volcanic islands.
As all the other trenches on the plate boundaries of the Pacific plate, the Aleutian Trench, on the boundary between the Pacific and the North American plate, has also come to be because of the subduction zone appearing between the two plates.
The lower and heavier Pacific plate is subducting bellow the North American plate, and that results into large deep spaces opening up between the two plates, thus the emergence of the trenches. Also, because the magma from bellow the crust has easy access to the surface, it comes upwards and creates multiple islands with the volcanic activity that it produces.
