What do you need help with?
Answer:
The size of the moon ensures that it has some considerable gravitational force associated with its mass. This is unlike asteroids that are not large enough to have significant gravitational forces associated with their relatively low mass. Therefore when the moon was molten in its early years of formation, gravity due to its mass, caused materials to be pulled down towards its center. The molten rock, before it cooled into solid rock, got distributed more or less into a sphere because the force of gravity pulls from all sides from the center of mass.
Protein lactoferrin is present in
human body and it is found in certain body fluids such as saliva, breast milk and
urine. The main function of protein lactoferrin is to bind with and transport
iron in the body. When an infant absorb iron in breast milk, protein
lactoferrin attaches to any of the extra iron that the infant does not absorb
and stops it from allowing harmful pathogens such as bacteria to grow in the
baby's gastrointestinal tract. Thus, protecting babies from illness and
infections.
