The action that BEST demonstrates the transformation of mechanical energy to heat energy is burning a candle (Option B).
Mechanical energy refers to the energy contained by an object due to its motion and/or position. Heat energy refers to the energy caused by the movement of atoms and/or molecules.
Energy transformation refers to the process by which the energy of an object changes from one type to another.
Mechanical energy can be converted into heat energy and vice-versa.
For example, thermal (heat) energy can be used to generate mechanical energy that produces the movement of a turbine generator, which subsequently converts mechanical energy into electrical energy.

Answer:
a Anaphase I
b Metaphase I
c Telophase I
d Anaphase II
e Prophase I
f Telophase II
Explanation:
Prophase I begins after the DNA has been duplicated, as shown in picture e. The chromosomes are condensed, and also visible, which is apparent in picture e.
The next stage is called Metaphase I, in which the pairs of homologous chromosomes align at The the centre of the cell and the spindle fibres attach, as shown in picture b.
The pairs of chromosomes are pulled apart to opposite poles of the cell by the spindle fibres., as shown in picture a. This stage is called Anaphase I.
Then, a process called Telophase I occurs, when the cell divides into two daughter cells. One of these cells is shown in picture c.
Picture d shows the stage Anaphase II, where the spindle has attached and the chromatids are pulled to the opposite poles of the cell.
The final picture left is picture f, which shows the daughter cell at the end of meiosis II, where the nuclear envelope is reforming, as in telophase II.
Answer:
El aparato circulatorio unidireccional transporta sangre a todas las partes del cuerpo. Este movimiento de la sangre dentro del cuerpo se denomina «circulación». Las arterias transportan sangre rica en oxígeno del corazón y las venas transportan sangre pobre en oxígeno al corazón.
Explanation:
Answer:
Use 400 x in order to study the structure clearly.
Explanation:
Cell structures could be clearly identified when magnify the microscope about 400 x by using a compound microscope. Due to high magnification power of compound microscope, the individual is able to see different structures that are present in cells. while by using lower magnification, the individual is unable to see different structures clearly. So use high magnification in order to study the cell.
