Baby Brain Power
Which sentence BEST explains how the
introductory paragraph contributes to the
development of ideas in the passage?
The author uses the term "control center" to
illustrate the importance of caregivers in brain
development
Speech, emotional regulation, movement, and
vision-all of these extraordinary abilities and
many more are possible thanks to the organ
that serves as the body's control center. When
one thinks of "brain power," it is the faces of
adult inventors, professors, and novelists that
likely come to mind. Remarkably, the most
critical time period with respect to brain
development occurs relatively soon after an
individual is born.
The author uses the examples of emotional
regulation, movement, and vision to contrast the
brain with other organs in the body.
A newborn enters the world as a fairly helpless
creature, but her brain has billions upon
billions of specialized cells called neurons.
The author uses the word "critical" to suggest that
adulthood is an essential time for the growth of the
brain.

about brain development differ from the reality

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

the narrator is a first person, participant one, who describes in the simple past tense important and difficult events in his earlier life. he also provides temporal markers as the month (january) and the time (12: 30 pm). finally the account of his experience is very detailed, to the extent that a participant narrator would talk the same way about his experiences. a good example of such detail is the mention of the “bovril ration” which historically was a native american food adopted by european explorers in arctic and antarctic regions due to its high level of calories.
