Why is it important scientists haven’t identified a lokiarchaeota cell yet

Well, scientists are working hard to find out more about cells, so they should know all of the cells. The Lokiarchaeota cell is one of the only ones they have yet to find out stuff about. Scientists also need to know about it, because it is a part of our bodies, and maybe sometimes they can cause infection in the body. Scientists need to know if it could lead to some of the biggest infections ever. 

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
