Why does the amount of heat received by places far from the equator become less?
Ainat [17]
If the Earth were a disk with its surface perpendicular to the rays of sunlight, each point on it would receive the same amount of radiation. <span> However, the Earth is a sphere and aside from the part closest to the sun, where the rays of sunlight are perpendicular to the ground, its surface tilts with respect to the incoming rays of energy with the regions furthest away. Hope this answers the question.</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.

Which is a tough and flexible layer that surrounds plant cells, as well as some algal and bacterial cells?
Vika [28.1K]


This layer is called the cell wall.

The cell wall is located outside the cell membrane and provides the cells with structural support and protection.  It gives cells rigidity and strength, offering protection against mechanical stress.

In most cells, it is flexible, meaning that it will bend rather than hold a fixed shape, but has a lot of tensile strength which is necessary to be able to withstand internal osmotic pressure.

Cell walls are found in plants, bacteria, fungi, algae and some archaea.
