Mamont248 [21]
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>

Brain cells that are neither neurons nor glia, but which are capable of dividing and then differentiating into neurons or glia,
solong [7]

ANSWER:

Brain cells that are neither neurons nor glia, but which are capable of dividing and then differentiating into neurons or glia, are called NEURAL STEM CELLS.

EXPLANATION:

Neural stem cells are undifferentiated cells originating in the central nervous system.

Neural stem cells (NSCs) have the potential to give rise to the radial glial progenitor cells that grow and differentiate into neurons and glial cells.

NSCs have an important role during development producing the enormous diversity of neurons, astrocytes and oligodendrocytes in the developing CNS.

A NEURON (nerve cell) is a specialized cell that conveys electrochemical impulses throughout the body.

provide support for and insulation between them.

GLIAL CELLS are the most abundant cell types in the central nervous system. Types of glial cells include oligodendrocytes, astrocytes, ependymal cells, Schwann cells, microglia, and satellite cells.

Anni [7]
Answers – 
1. Macroeconomics
2. Economic cycle

1. Macroeconomics refers to the study of the whole economy and how it behaves. It is a branch of the field of economics which carefully examines various economy-wide phenomena like, inflation, price levels, national income, GDP (gross domestic product), growth rate, and changes in unemployment.

2. The time from one economic peak to another economic peak is called the economic cycle. Like a roller coaster ride, the economic cycle is more or less like a behavioral pattern in the economy that consist of both growing and shrinking phases
