River water held behind a dam is a form of ________. group of answer choices
WINSTONCH [101]

Potential energy is present in the river water behind a dam.

<h3>How is potential energy defined?</h3>
  • Potential energy is a form of stored energy that is dependent on the relationship between different system components.
  • When a spring is compressed or stretched, its potential energy increases.
  • If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy.
  • The object's mass, its mass in relation to some reference points, and the gravitational field it is in all affect the potential energy of the object.
  • Joule is the SI unit of potential energy as a result (J)
  • As weight and height increase, gravitational potential energy rises.

an experiment is designed to compare the differences in learning outcomes between learning math from s video game and learning i
jeyben [28]

Answer: the dependent variable was the learning outcome.


Explanation:


1) The dependent variable is the variable that is explained by the indepent variable.


The dependent variable is not changed or fixed by the experiment, but it is a response from the change in the independent variable.


2) The independent variable is the variable that can be changed arbitrarily (inside the physical restrictions).


In this case, the variable that is changed at will of a part (may be the own will of the students or an imposition of the teacher, or other reason, it does not matter), is the kind of activity to learn: either learning from a video game or from traditional classroom activities).


Therefore, the independent variable is the kind of learning mode.


On the other hand, the learning outcome is the variable studied. The experiment is meant to determine how the learning outcome is related or explained by the kind of learning activity.


Therefore, the learning outcome is the dependent variable.

The observed differences in amplitudes are due to interference between the sound waves. The decrease in amplitude is due to destructive interference of the waves and the increase in amplitude is due to constructive interference.

Termination of translation requires a termination signal, RNA polymerase, and a release factor. a release factor, initiator tRNA
Neporo4naja [7]
  • termination signal
  • a release factor

Termination of translation requires a termination signal, and a release factor

Explanation:

There are 3 stops codons of the 64 possible codons. These are UAA, UAG, or UGA. These do not code for amino acids and are therefore not recognized by any anticodons for any of the ‘charged’ tRNA. These codons, are recognized by release factors that ‘knock off’ the newly synthesized peptide from the ribosome through peptidyl-tRNA hydrolysis. There are several release factors (RF1 and RF2) in bacteria but in eukaryotes only one RF has been discovered to recognize the 3 stop codons.
