Catalytic ozone destruction occurs in the stratosphere where the reactions involving bromine, chlorine, hydrogen, nitrogen and oxygen gases form compounds that destroy the ozone layer. The reactions uses a catalyst (speeds up the reaction) in a two step reaction. considering chlorine the reactions appears as follows;
step 1
Cl + O3 = ClO + O2
step 2
ClO + O = Cl + O2
Where by chlorine is released to destroy the ozone layer, this takes place many times even with the other elements (hydrogen, bromine, nitrogen) and the end result is a completely destroyed Ozone layer
Average speed = (total distance) / (total time to cover the distance)
= (90km + 60km) / (1hr + 3hr)
= (150 km) / (4 hr)
= 37.5 km/hr .
Answer:
the reason why the crate won't move to the direction of the force being applied (F app). is because the (Fgravity) is pulling it down making it heavy to move
The correct answer is the amoeba will deploy its pseudopods (cytoplasmic extentions) to capture the prey and phagocyte.
The amoeba most known and probably the most representative of the kind. Large (up to 500 microns), common in stagnant waters, extremely voracious as evidenced by multiple digestive vacuoles.
Amoebae are characterized by a deformable cell body emitting changes of shape, the pseudopods, which allow them to crawl on a support or to capture microscopic prey by phagocytosis.
Answer:
I dont think the universe has a center because there is such a vast majority of stars, planets, and galaxys that havent even been discovered that space could be endless. so no i dont think there is a center to the universe.
