Ican summarize the hypothesized early atmosphere and experiments that suggest how the first “cells may have evolved and early conditions affected the type of organism that developed. ( describe how miller and urey’s experiment relates to earths [hypothesized] early atmosphere and the first cells, tell the the order in which various types of cells appeared on earth) use the words: evolution, miller and urey, endosymbiosis, homologous structures and analogous structures in your answer.

Ion channels are pore-forming membrane proteins that create a gated, water-filled pore to help establish and control voltage potential across cell membranes through control of the active flow of ions between the intracellular and the extracellular environments

Explanation:

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

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
