Of the important biological molecules only the non-polar lipids (fats and oils) and large polymers (e.g. polysaccharides, large proteins and DNA) do not dissolve. The water acts as a solvent for chemical reactions and also helps transport dissolved
Average speed =
(total distance covered)
divided by
(total time spent covering the distance)
a=(Vf-Vi)/t = [(0 m/s)-(45m/s)/(10s)=-45/10m/s^2= -4.5m/s^2
Answer:
The biggest of all these was, and perhaps still is, the ongoing fascination with whether we, the United States of America, in July 1969 actually landed on the moon — where, ahem, astronaut footprints are still visible.
Explanation:
Answer: Sea otter is the pioneer species in the kelp forest as it regulates and controls the population of other species in the kelp forest.
Explanation:
If sea otters are hunted and their population is brought to extinction then this will cause major harm the ecosystem of the kelp forest and it will disturb the ecological balance in the kelp forest. The herbivorous animals consumed by the sea otters will increase in population and they will consume a lot of vegetation in the forest. The kelp forest which forms the coastline will not remain effective in providing protection against the storms to the neighboring areas.
