During that time telescopes were still not as advanced and could only see so much, nowadays they are much more advanced and these galaxies are being analyzed and understood more clearly.
Acceleration of a body is defined as rate of chance in velocity with respect to time and its S.I. Units are 
/ or 
Magnitude of average acceleration of a body = (final speed - initial speed)/time interval = 
where, final speed =v= 11 m/s; initial speed = u = 6 m/s; and time interval = t = 3 s
Hence acceleration = 
= 
= 
<span>Cellulose is a lot stronger than starch. Starch is practically
useless
as a material, but celluose is strong enough to make fibers from, and
hence rope, clothing, etc. Cellulose doesn't dissolve in water the way
starch will, and doesn't break down as easily.
</span>Your body contains
enzymes that break starch down into glucose to fuel your body. But
we humans don't have enzymes that can break down cellulose.
