1) Use the map to describe the motion of the plates at this boundary and the age of the rocks along each
side of the ridge.
2) Explain the importance of this discovery to the current theory of plate tectonics.
<span>Ans : The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound is 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or a kilometre in 2.91 s or a mile in 4.69 s.
The speed of sound in water increases with increasing water temperature, increasing salinity and increasing pressure (depth). The approximate change in the speed of sound with a change in each property is:
Temperature 1°C = 4.0 m/s
Salinity 1PSU = 1.4 m/s
Depth (pressure) 1km = 17 m/s</span>
Answer is b. Decreasing ; increasing
Neuropeptides are a class of messenger molecules present in central nervous system of many mammalian brain. About 100 different neuropeptides made and release from the hypothalamus of mammalian brain. A neuropeptide, after release may diffuse in the blood to exert its action on sleep, alertness, anxiety. Thus, neuropeptides play key roles in modulating neuronal activity.

Answer: Mechanical Isolation
Explanation:
Mechanical isolation is a type of barrier that prevents the species that are closely related from mating with each other.
It is used in case of plants and animals(here beetles) in which the without compatible sex organs individual of different species will not be able to mate and produce offspring.
Thus, the correct answer is option C
