You call to a friend from a boat floating in the ocean. Which best describes the changes in the speed of the sound waves as they
Alina [70]

The correct answer is: The speed of sound is faster in the water than in the air.  

The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.

What structure is most important in forming the tetrads?
Vladimir79 [104]

Answer:

The correct answer will be option- synaptonemal complex.

Explanation:

The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex.  The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.

The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.

Thus, option- synaptonemal complex is the correct answer.
