Known as the cell’s “command center,” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information. Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid). RNA helps convey the DNA’s orders to the rest of the cell and serves as a template for protein synthesis.

Answer:
Explanation:
1- closely packed osteons or haversian systems, used to provide strength and protection to bones.
2- Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. provides balance to the dense and heavy compact bone by making bones lighter so that muscles can move them more easily.
Solve the
potential energy at point B
PE = mgh
Where m is
the mass
G is the
acceleration due to gravity 9.8 m/s2
H is the height
PE = ( 1.5
kg) ( 9.8 m/s2) (0.5 m)
PE = 7.35 J
Solve the
velocity using the
KE = 0.5mv^2
Where ke is
the kinetic energy
M is the
mass
V is the
velocity
Since all
energy is converted to KE
So KE = PE
7.35 = 0.53(1.5)
v^2
V = 3.13 m/s
