Answer:

difference:

1. The generation mechanism is different, the mechanical wave is generated by mechanical vibration; the electromagnetic wave generation mechanism is also different, there is the periodic movement of electrons (radio waves); the outer electrons with atoms are generated after being excited (infrared, visible, ultraviolet) The inner electrons with atoms are generated after excitation (roentgen rays); the nuclei with atoms are generated after excitation (gamma rays).

2. The propagation mechanism is different: the mechanical interaction between the particles and the alternating induction of the electromagnetic field.

3. Mechanical waves have both transverse waves and longitudinal waves; electromagnetic waves are material waves and belong to transverse waves.

4. The influence of the medium on the propagation speed is different

Explain what takes place in each step of the diagram

Andrei [34K]

The given image is showing the interaction of the enzyme and its substrate.

In the first part of the image, the enzyme and substrate are not bind together. They are present in close proximity. The enzyme shown in the picture have a site for the attachment of the substrates.

In the next picture, the interaction of the enzyme and the substrate has occurred, which resulted in the formation of the enzyme substrate complex. Hence, the given picture shows the interaction of an enzyme with the substrates.

D. Fertilized egg A zygote is a cell which is a diploid cell in the combination of the spem and egg cell. Furthermore, this cell which came from the parent cell was successfully fertilized at the fallopian tube of the female reproductive system. A zygote will develop to become an embryo for the next few weeks.
