Simple diffusion and facilitated diffusion are related in that both
kaheart [24]

Answer:

allow the downward movement of the concentration gradient by passive transport

Explanation:

Passive transport is a process of substance transport, which is carried out spontaneously, without energy expenditure and in favor of the concentration gradient, that is, from a medium where the molecules are more concentrated towards a medium where their concentration is lower.

Three types of passive transport are distinguished: osmosis, simple diffusion and facilitated diffusion

<u>Simple diffusion</u>

It is the passage, through the plasma membrane, of small molecules without charge soluble in the lipid bilayer, such as some gases (oxygen and carbon dioxide). For a molecule to diffuse through the membrane it is necessary that there is a difference in concentration between the external and the internal environment.

<u>Diffusion facilitated </u>

There are molecules such as amino acids, glucose and small ions that, due to their chemical and size characteristics, cannot diffuse through the lipid bilayer and require transport proteins for diffusion.

The transport proteins are immersed in the plasma membrane and can be of two types: protein channels, formed by proteins that generate a channel in the membrane, and permeases, which are proteins that, when joined to the molecule to be transported, change their shape by carrying them into the cell.

What would happen if a rocket ran out of fuel in the Earth's atmosphere?
nydimaria [60]
It would do exactly what a rock or a frisbee does when you toss it.

After the engines cut off, it couldn't get any more energy from
anywhere, and after that, as it pushed air aside to get through,
and had air molecules scraping against it, those would slowly
rob kinetic energy from it.  Sooner or later it would run out of
kinetic energy, start falling, and it would eventually make either
a big 'SPLOOSH' or else a big 'CRUNCH', depending on exactly
where it returned to Earth's surface.

During an olympic bobsled run, the jamaican team makes a turn of radius 9.80 m at a speed of 96.6 km/h. what is the ratio of the
GREYUIT [131]

Answer:

Acceleration will 7.5 times g = 7.5 g

Explanation:

Centripetal acceleration is given by a = v²/r.

The speed in m/s will be; (96.6 Km/h )÷ 3.6

                                        = 26.83 m/s.

Centripetal force = v²/r

                            = 26.83²/9.80

                            = 73.454 m/s²

But; g = 9.8 m/s²

Therefore the acceleration in terms of g will be;

  = 73.454/9.8

   = 7.5 g

Acceleration is 7.5 g
