Default network


When the brain is unoccupied, an fMRI indicates that blood continues to flow via a web of brain regions called the default network.

The default network is a web of brain regions that have activity that corresponds greatly with each other and different from other networks within the brain. The default network is active when an individual's attention is not concentrated on the external environment and it is measured with the functional magnetic resonance imaging technique (fMRI).

A strand of DNA contains 10% Guanine, what<br> percent is Adeninc?
Wittaler [7]

Answer:

40% is Adenine.

Explanation:

In DNA, Guanine pairs with Cytosine and Adenine pairs with Thymine.

If a strand of DNA contains 10% Guanine, that means that it also contains 10% Cytosine.

10% G + 10% C = 20%

100% - 20% = 80% (Adenine and Thymine)

80% ÷ 2 = 40%

The strand of DNA contains 10% Guanine, 10% Cytosine, 40% Adenine, and 40% Thymine.

Give a brief explanation of why food webs are preferred over food chains for representing the flow of energy in an ecosystem.
kow [346]

Answer AND Explanation:

Very often, one type of organism or species in an ecosystem happens to be the same food source for other types of consumers. The different food chains that exist in an ecosystem therefore form a complex network called food web.  Food webs are more complex than food chains and therefore there can be more than one primary producer thus increasing the flow of energy an ecosystem.
