The system that is responsible for breaking down food and releasing essential nutrients and other substances that the body needs and requires is the digestive system.
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

Answer:
The dependent variable is the variable that is being measured or tested in an experiment.
Explanation:
For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores since that is what is being measured.
The best answer is A.
A restriction enzyme is an enzyme that catalyzes the cleavage of DNA after recognizing a specific sequence of DNA.
Restriction enzymes are proteins produced by bacteria that cut DNA at specific sites. These enzymes are used by bacteria to defend against bacterial viruses known as bacteriophages. When a phage infects a bacteria, it inserts its DNA into the bacteria so as to be replicated.
The restriction enzyme thwarts the replication of the phage DNA by cutting it into many pieces. These enzymes have been isolated from bacteria by scientists and used as indispensable tools in recombinant DNA technology.
