The power house of the cell
only thing I remember from freshman year
Answer:
The more neurons involved, the more powerful the contraction
Explanation:
The motor unit can be defined as the functional unit for muscle contraction, which consists of a motor neuron and the associated muscle fibers it innervates. The number of associated muscle fibers varies depending on the muscle’s ability for contraction. Muscles with a higher number of motor units can modulate force output more finely. The number of muscle fibers per motor unit is inversely proportional to the force that it generates, and while higher is precision, lesser is the size of the motor unit. A higher number of neurons is required for controlling motor units with lesser size, thus being greater the brain's control over the extent of shortening.
Answer;
The important role of experience in wiring the brain
Explanation;
-Brain development involves creating, strengthening, and discarding connections among the neurons; these connections are called synapses.
-These synapses organize the brain by forming pathways that connect the parts of the brain governing what we do.
-At birth the synapses present are those governing our bodily functions such as heart rate, breathing, eating, and sleeping.
Some people who score below average on intelligence tests have an island of brilliance, which refers to some incredible ability, such as heightened musical memory. This condition is known as Savant Syndrome.
Answer:
The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with an infinitely hot, infinitely dense singularity, then inflated — first at unimaginable speed, and then at a more measurable rate — over the next 13.8 billion years to the cosmos that we know today.
Because current instruments don't allow astronomers to literally peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical formulas and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.
While the majority of the astronomical community accepts the theory, there are some theorists who have alternative explanations besides the Big Bang — such as eternal inflation or an oscillating universe..
