It has to do with vibrations being able to travel through the air when the tuning fork was struck the vibrations made the air around it vibrate as well and when the vibrating fork got near the string the vibrating air made the string vibrate as well.

An example would be mitochondria, vacuoles, lysosomes, etc.
Answer:
C
Explanation:
For standing waves, the areas where the amplitude is zero are referred to as nodes while the areas where the amplitude is at the maximum are known as antinodes.
A standing wave derives its feature primarily from the fact that there are certain points along the medium of transmission that are apparently seeing to be standing still with no displacement whatsoever. At the same time, there exist opposing points to the points of zero displacements. These points have a maximum displacement in both the positive and negative directions. While the former is referred to as nodal points, the latter is known as the antinodal points.
Answer:
It enables it to be left with little or no resistance
Explanation:
The pinewood nematode , Bursaphelenchus xylophilus is a plant-parasitic nematode that causes severe death of pine trees.
The pine trees developed a mechanism over the years by producing a chemical compound called α-pinene . This helps in fighting against the nematodes. If enzymes are produced to digest this chemical then the pine wood nematode will thrive well and result in the death of the pine trees.
The correct answer is: sea stars
All animals listed above are invertebrates. One of the characteristic of invertebrates are that they are protostomes with the exception of Echinodermata (sea stars). The difference between protostomes and deuterostomes is in their embryonic development (orgin of mouth and anus).
In protostomes the mouth forms first: the oral end of the animal develops from the first developmental opening. On the other hand in deuterostomes the first opening (the blastopore) becomes the anus, and the oral end of the develops from the second opening.
Humans are also deuterostomes.
