None of the provided options are reasonable. <span>comparing nutrient concentrations between the photic zone and the benthic zone can not tell you whether differences in concentrations between the photic and benthic zone are due to uptake by phytoplankton or because nutrients are sinking to the sea bottom and ocean stratification is preventing mixing. The approach of c</span><span>ontrasting nutrient uptake by autotrophs at different locations under different temperatures would not provide useful information on limiting nutrients. but rather uptake rates at different temperatures. It is likely that e</span>xperimentally enriching some areas of the ocean and compare their productivity to that of untreated areas can provide an indication of limiting nutrients, but this is not advisable, as it would have to be done on a large scale, and one cannot be sure of the ecological consequences. Also, because it would not be a controlled experiment, other factors could create 'noise' in the data. The last option, <span>observe antarctic ocean productivity from year to year to see if it changes, also does not help, as there is no correlation between nutrient concentrations using this approach. The best approaches would be either the last approach, but with the additional monitoring of nutrient concentrations, or under a controlled laboratory experiment.</span>
Answer:
Anemic Hypoxia.
Explanation:
As per the definition of this condition:
"Anemic hypoxia occurs when the oxygen carrying ability of the blood decreases, and thus, this defect is specifically associated with the blood. This implies that fewer hemoglobin molecules (or oxygen-binding sites) are available for binding oxygen."
Hope this helps!
Answer:
B
Explanation:
The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first)

A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular.Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall. When looking under a microscope, the cell wall is an easy way to distinguish plant cells.
Difference Between Plant And Animal Cells 1 Chloroplast. Like animal cells plant cells have mitochondria. 2 Cell Wall. Animal cells do not contain a cell wall while plant cells and fungi cells do. 3 Vacuole. Vacuoles are very large membrane-bound sacs within plant cells.
