Extinction DIF; Having no more existing or living members
Commensalism is the relationship between two organisms where one benefits from the other and the other is not affected in anyway. The interaction between the remora and the shark demonstrates this relationship.
Answer:
Metamorphic rocks are almost always harder than sedimentary rocks. They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.
Because their mineral grains grew together tightly during metamorphism, they're generally strong rocks.
D. Electromagnetic waves
<span><span> Generally, Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase.</span><span>The creation of all electromagnetic waves usually begins with a charged particle, which creates oscillating electric and magnetic fields.</span><span>Once they are in motion, the electric and magnetic fields that are charged in particles creates are self-perpetuating: time-dependent change in one field (electric or magnetic) to produce the other.</span></span>
