There are two major sources of energy that power the earth's environmental systems, these are SUN AND THE EARTH'S INTERIOR HEAT.
The heat energy from the sun is the one responsible for processing all the external processes that occur in the atmosphere, hydrosphere and on the earth surface.
The energy from the earth's interior is the one that is respondsible for powering the internal processes that produce earthquakes, volcanoes eruptions and mountain formation.
Answer:
alternating sugar (ribose) and phosphate groups also -adenine (A), uracil (U), cytosine (C), or guanine (G).
Answer:
A
Explanation:
A - Phospholipids are the most abundant lipids present in the plasma membrane of each cell.
B - While it is true that lipids are sources of energy, phospholipids do not produce energy for the cell. The mitochondria is the cell organelle which produces energy in the form of ATP for cellular processes and respiration.
C - Phospholipids are not capable of storing genetic information. The nucleus contains genetic information in the form of DNA.
D - Enzymes are responsible for increasing rate of reactions. Most enzymes are protein in nature, which is another class of macromolecules. Phospholipids are not protein in nature (they are lipids) so they do not possess enzymatic properties that allow them to increase rate of reactions.
Ecological systems often remain in balance if only one factor is altered.
