Answer:
If heart disease is suspected, we use two-dimensional doppler imaging technologies that take in-depth images of the heart. The doppler system records sound waves as they bounce off blood cells in your heart and change pitch. The blood flow shown in these images is colorized to better detect any problems.

What is depicted as the yellow arrows in the following image? (Using a scientific vocabulary word we learned in class and provide its definition) Which makes a bigger current- faster moving electrons or slower moving electrons?
Answers
Answer:
Electric Current
Explanation:
The yellow arrows in the following image depict electric current. Electric current is defined as the continuous flow of electrons in an electric circuit. Electrons present in the conducting material which move from one to another atom randomly from the negative terminal through the connecting wires and back to the positive terminal.
Faster moving electrons make a bigger current because faster moving electrons collide more with each other that generates more heat which results into a higher current.
Hence, The yellow arrows in the following image depict electric current and Faster moving electrons make a bigger current.
The yellow arrow in the diagram shows the flow of electrons.
Current is defined as the flow of electrons in a circuit. The yellow arrows represents the direction of the flow of electrons in the circuit. The battery provides the potential difference that drives the flow of electrons through the wire.
Since current has to do with the movement of electrons in a circuit, the faster the movement of the electrons, the bigger the current.

C. They are nonspontaneous.
D. Oxidation happens at the cathode.
Answers
Answer:
reduction happens at the cathode
Explanation:
Just took the test.
Reduction happens at the cathode. Hence, option A is correct.
What is an electrolytic cell?An electrolytic cell converts electrical energy into chemical energy or vice versa.
Oxidation-reduction reactions are balanced by two half overall chemical equations into an oxidation equation and a reduction equation.
Hence, reduction happens at the cathode in both galvanic and electrolytic cells.

Which choices are layers of the atmosphere?
Select the five correct answers.
Thermosphere
Meteorosphere
Croposphere
Stratosphere
Mesosphere
Danosphere
Exosphere
Troposphere
Answers
Answer:
Mesosphere
Stratosphere
Thermosphere
Troposphere
Exosphere
Explanation:
The exosphere refers to the farthest region of the atmosphere that gradually fades into space.
The troposphere is the lowest layer of atmosphere. It is the layer where weather changes occur.
The thermosphere is right above the mesosphere but just below the exosphere. It is the layer where photoionization/photodissociation of molecules occurs thereby creating ions. This largely owes to interaction of molecules in this layer with ultraviolet radiation.
The stratosphere is composed of gases. Prominent among them is ozone which serves as a blanket against the sun's ionizing radiation.
The mesosphere lies above the stratosphere but just below the thermosphere. Temperature decreases steadily with height in the mesosphere.
