The correct answer to this open question is the following.
In one study of reading and math ability in third- and fifth-grade children, the researchers found that high-scoring children usually had three sources of cognitive stimulation. Media was not a source of cognitive stimulation.
Scientist highly recommend mental stimulation for children to develop the part in their brains that work on language and cognition. Children must have activities that improve alternating attention, that foments inhibition, and that improve their semantic memory.
Answer:
Functional magnetic resonance imaging (fMRI)
Explanation:
The technique of fMRI was developed by Seiji Ogawa and Ken Kwong.
Functional magnetic resonance imaging (fMRI) is the technique that is used to help measure the brain activity. This brain activity is detected by the changes in the flow of blood circulation or oxygenation. Circulation of blood is more in the area of the brain where there is more activity,
<u>In the given case, Parsons et al. will use the technique of fMRI to detect the brain activity of patients suffering from schizophrenia and psychological disorders</u>.
So, the correct answer is Functional Magnetic Resonance Imaging (fMRI).
The central Africa region includes places such as Chad, Congo and Angola. The Equator lies within the region: it goes through Both Congos (The Republic and the Democratic Republic), which are part of the Central Africa region.
So the statement is false.
Answer:
Explore opportunities to increase the storage capacity of existing reservoirs by raising dams. Often, this can be more cost-effective and have lower environmental impacts than a new dam project. It may also be possible to improve the use of existing storages by providing greater interconnection between storages
Explanation:
1) Different strategies can be used to increase water supply. The World has enough water for everyone, but its availability varies from place to place and time to time.
2) Dams and reservoirs.
3) Water transfers.
4) Desalination.
Hope it helps :)
