When selecting a vitamin-mineral supplement, one should be careful to choose one that has nutrient levels that are less or equal to the RDA, but not exceeding it.

Bundles of axons in the central nervous system are called
Karolina [17]

Answer: Bundles of axons in the central nervous system are called a "tract"

Explanation:

Axons(nerve fiber) consist of long slender projection of neurons or nerve cells that conduct and transmit impulses away from the neuron or nerve cell body. Axons are surrounded by endoneurium layer which contain protein fluid that surround each axon.

Bundles of axon in the CNS is known as tract. We have ascending tracts and descending tracts. The ascending tracts function are to conduct and carry impulses along the spinal cord to the brain while the descending tracts transmit and carry the impulses from the brain to lower regions (downward) of the body. Tracts are identified by their origin (where the bundle start) and also the end/termination of axon bundle.

The largest tracts are fasciculi gracilis and cuneatus which are known as ascending tracts.

Darwin and wallace's theory of evolution by natural selection was revolutionary because it _____.
Lisa [10]
<span>Notice a couple of things different between (A) and (B). It was NOT the first time a biologist proposed that species changed through time (so it's not B). But it finally *solidified* that idea by giving "change through time" (evolution) a MECHANISM. It gave a plausible explanation for WHY species change over time, in a testable way that made sense and had evidence to support it.

So it finally dismissed the idea that species are constant.

It also emphasized that the simple presence of *variation* within a population was a key reason for evolution.

While we're at it ... (C) is wrong because it's not *individuals* that acclimate (adapt) to their environment, but the population (the species) as a whole.

And (D) is wrong because it had nothing to do with economics or the monarchy.</span>
