Tropical forests contain dense trees, which allow less sunlight to penetrate. Emergent trees are trees that grow to a height of

more than 45 to 55 meters, above the usual height of trees in tropical forests. Which system provides the best possible explanation for why these trees grow to those heights?
growth pattern
homeostasis
nervous system coordination in plants
phototropism

The best possible explanation is phototropism.
Since the trees are very dense, some plants don't get enough sunlight. A reaction to this is to seek out sunlight. This would result to trees growing taller than the rest in order to obtain sunlight.<span />

What would be the best explanation for why myelinated fibers conduct signals faster than unmyelinated fibers?
Sliva [168]

Answer: The diffusion of ions along the axoplasm is faster,in myelinated compare to unmyelinated,

Neurons are the structural and functioning units of nervous system.They are the vehicles for transmission of impulses as electrical signals from one part of the cells,and from one part of the body to another.

The basic structural components of a typical neuron are the cellbody, the axon, and the dendrites.

Based on structure neurons are classified as myelinated and unmyelinated.This is based on the the surrounding layer of myelin sheath around the axon. The myelin provides the insulating layer for the axon.And ensures fast movement of impluses.

In myelinated neurons the myelin sheath are interrupted at intervals by gaps along the length of the axon called Nodes of Ranvier. These gaps contains more Na-K channels for influx and out-flux of K and Na+ ions for transmission of impulses.

The cytoplasm of axon is called axoplasm,Since this is surrounded by myelin sheath which contains Na-K+ channels,The rate of diffusion of ions along  these channels is faster for depolarization to take place than in unmyelinated neurons. Inaddtion as these ions  diffusion increases,its jump faster at the nodes of Ranvier (saltatory conduction) to the next axoplasm which further speed up the rate of transmission.

Unmyeinated lacks myelin sheath,therefore the exchange and  the rate of diffusion of ions along the axons is low.

An enzyme _____. is an organic catalyst is a inorganic catalyst can bind to nearly any molecule is a source of energy for enderg
Sidana [21]

An enzyme is an organic catalyst.

<h3>What is an enzyme?</h3>

Enzymes are proteins that help speed up metabolism or the chemical reactions in our bodies.

They build some substances and break others down.

All living things have enzymes. Our bodies naturally produce enzymes.

But enzymes are also in manufactured products and food.

Examples of specific enzymes:

Amylase: In the saliva, amylase helps change starches into sugars.

Maltase: This also occurs in the saliva, and breaks the sugar maltose into glucose.

Trypsin: These enzymes break proteins down into amino acids in the small intestine.
