B. all eukaryotic cells
hoped this helped!
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

B because the periodic table tells you the groups of the elements
Answer:
The water vascular system of echinoderms (B) functions in locomotion and feeding.
Which of the following combinations of phylum and description is correct? (C) Platyhelminthes—flatworms, gastrovascular cavity, no body cavity
Explanation:
Echinoderms are marine animals. They have a water vascular system that make them able to move (locomation), respiration and food and waste transportation. This system is full of different canal along the body.
Echinodermata has not a radial symmetry as a larva, in fact it has a bilateral symmetry and coelom present. When it comes to Nematoda, they are roundworms and have a pseudocoelomate. Finally, porifera has a gastrovascular cavity and no coelom.
