Monosaccharides are simple sugar unit molecules, whereas polysaccharides are enormous, linking thousands of sugar units. Monosaccharides provide cells with short-term energy. Polysaccharides provide long-term energy storage and rigid structure to cell walls and exoskeletons of animals.
Answer:
(2) exchange food, oxygen, and waste between
mother and fetus
Explanation:
In most mammals like humans, the fetus produced as a result of the fertilization of the sperm and egg, develops in the uterus or womb of the female. However, this developing fetus cannot yet fend for what it requires for survival and is still dependent on the mother e.g nutrients, oxygen etc. How do this substances get to the fetus?

Answer:
An inclined plane is a simple machine. An inclined plane is a ramp used to reduce the effort needed to raise or lower an object over a vertical height.
It is easier to climb stairs to get to a second floor than to climb straight up a rope. It is easier to walk up a long, gentle hill than to climb up a short, steep hill
, both condition work is done by gravity which is conservative force. So work is same. But if we will take friction force then for your kind information total world done on plane will be more than stairs due to longer path of plane were against of non conservative force.
The following are examples of inclined planes:
* Loading ramp
* Stairs or wheelchair ramp
* Mountain road
* Threaded screw.
The ancient Egyptians used inclined planes, or ramps, to move huge blocks of stone to build the pyramids.
