Answer:

Statements A,C, D and E are correct while statement B is wrong

Explanation:

A. During depolarization phase, the gated sodium ion channels on the neuron's membrane opens for the flow of sodium ions (Na+) into the cell.

C. Once the threshold of depolarization reaches, action potential will occur.

D. Hyperpolarization inhibits action potentials by increasing the stimulus required to move the membrane potential to the action potential threshold.

E. Finally, the cell is brought back to its resting membrane potential by the reflux of extra K+ ions out of the cell via the potassium leakage channels.

B is wrong because at rest, excited cells are negatively charged

While distinctly Anthropoids, some Platyrrhines maintain a few of traits that are typically represented only in Prosimians. For

crimeas [40]

Convergent evolution is the concept of two or more species evolving similar traits despite being completely unrelated to one another, including the absence of a common ancestor.

The Platyrrhines, more commonly known as "New World Monkeys", share many characteristics with the Prosimians. Some of these include:

Teeth layout
Diet
Eyesight
Sleeping habits

and more.

The Platyrrhines and the Prosimians are both nocturnal animals. Despite all other members of their family being active during the day, the Playrrhines have evolved nocturnal habits similar to that of the Prosimians. Aside from that, they feed on insects more so than fruit, which is reflected by the layout of their teeth, and have eyesight well adapted to dark conditions. All of these are traits they share with the Prosimians.

Despite being in different ecosystems and regions, and sharing no recent common ancestors, both of these species have evolved strikingly similar traits. This can be used to corroborate the theory of convergent evolution, which explains how two species can evolve very similar traits despite being unrelated.

"the ________ is the deep groove that separates the brain into two halves."

yKpoI14uk [10]

The biggest part of our brain, the cerebrum is separated into two halves, the left and the right hemisphere by a deep groove that is called the longitudinal fissure or cerebral fissure.
The hemispheres are connected by a bundle of nerve fibers called the corpus callosum in order to enable communication between the two of them, as their communication is necessary for various cognitive functions of the brain.
