Explain one way in which facilitated diffusion is the same as simple diffusion and one way in which it is different from simple

diffusion.
Biology

Vilka [71]3 years ago

Answer:

1. Both facilitated diffusion and simple diffusion move substances according to the concentration gradient.

2. Facilitated diffusion uses membrane transport proteins while simple diffusion does not use them.  

Explanation:

Both facilitated and simple diffusions are the passive processes. This means that these two processes do not use the energy to transport substances. Rather concentration gradient of the substance moves them spontaneously. Therefore, both the processes move substances from higher to lower concentration.  

However, facilitated diffusion uses channels and carrier proteins to move the polar and charged particles that cannot diffuse freely across the membrane.  channels and carrier proteins are the membrane proteins. Simple diffusion does not involve membrane transport proteins.

Explain why are the constrllations of the zodiac seen in both boston and brazil?
marishachu [46]

Answer:

Because Circumpolar constellations are constellations that never set below the horizon when seen from a particular location on Earth.

They can be seen in the night sky throughout the year, while other constellations are seasonal, visible only at certain times of year.

The term circumpolar refers to constellations and stars that are circling the north and south celestial poles without ever dipping below the horizon. All circumpolar constellations are found near the celestial poles and, due to their proximity to the poles, they never disappear from view.

The five northern constellations visible from most locations north of the equator throughout the year are Cassiopeia, Cepheus, Draco, Ursa Major, and Ursa Minor.

The three southern circumpolar constellations visible from most locations in the southern hemisphere are Carina, Centaurus, and Crux.

Other constellations are just as prominent in the sky and can be seen for most of the year, but only these eight are circumpolar.

B. Green


Chlorophyll is found in and around the photosystems embedded in the thylakoid membrane of the chloroplasts.

The chloroplasts are organelles found in eukaryotic algae. The chloroplasts in eukaryotic celss are contained in the cytoplasm together with other organelles.

<span>Since the chlorophyll is insided the chloroplast which is inside the cytoplasm, it is safe to say that the chlorophyll of the green algae is spread throughout the cytoplasm of its cells.</span>

I'm working on a lab report on water erosion on edg lol
melomori [17]

Some facts about Water erosion :

Water erosion is the detachment and removal of soil material by water. The process may be natural or accelerated by human activity. ... Water erosion wears away the earth's surface. Sheet erosion is the more-or-less uniform removal of soil from the surface.

Water and Wind Erosion (cause)

Water erosion is the removal of soil by water and transportation of the eroded materials away from the point of removal. Water action due to rain erodes the soil and causes activities like gully, rill, and stream erosion leading to the downstream effects of flooding and sedimentation.

The amino acids of a growing polypeptide chain are held together by what kind of bond during the elongation stage of translation
kifflom [539]

Answer: Peptide bond

Explanation: A peptide bond is the covalent chemical bond  bond that holds together two amino acids which occurs when the carboxylic group of one molecule reacts with the amino group of the other molecule, linking the two molecules and releasing a water molecule catalyzed by peptidyl transferase, an RNA-based enzyme  integrated into the growing chain.

In the elongation stage ie when Long chain polypeptides are forming , peptide bonds  are formed by linking many amino acids to each other. These peptide bonds of amino acids are  relatively unstable, and  can break spontaneously in a slow process as can be seen especially  in enzymes of living organisms in the making and breaking of bonds.
