Parts of the inner ear include the cochlea, the semi-circular canals, and the lateral canal (which is one of the three semi-circular canals, also called the horizontal canal).
Answer:
The correct answer will be- the cell structures undergo repeated breakdown and formation.
Explanation:
The carbohydrates, fatty acids and amino acids are the three important bio-molecules which form the components of various cellular structures.
In the given question, the cell biologist radiolabeled these biomolecules and then observed the cellular structures after cell metabolism. He found that few cellular structures contained radiolabeled structures and few not. This showed that the cellular structures constantly undergo changes in their structures due to cellular metabolic reactions and are broken down and reformed.
Thus, the cell structures undergo repeated breakdown and formation is the correct answer.
<span>The role that Stratigraphic dating have played in determining the occurrence of mass extinctions is in its ability to identify different sediment debris. This includes rock and other materials that form or accumulate as the result of natural processes, human activity, or both</span>
A magnetic field is produced by movement of electrons. Electrons are charged particles. All magnetic fields are created by charged particles
During an experiment in the early 19th century, it was discovered that when an electric current flowed through a wire , a compass that had been placed nearby would change direction and when the current was turned off, the compass went back to its original North/South alignment with the earth's magnetic field.
The conclusion from this observation was that electrons moving through the wire were creating a magnetic field which was not there when the current was turned off.
Answer:
4x + 6y = 420
Explanation:
since x is number of child tickets and y is adult tickets, and $4 is the cost of child tickets and $6 is the cost of adult tickets, that eliminates A and D.
The question also states "for one day", so that elimates C, which C is the equation for two days.
This leaves 4x + 6y = 420
