Answer:
A. fossils of archaic humans show we have evolved through the differences in bone structure. Humans used to look a lot like chimps, and through fossils we can see differences in our skull shape and size, differences in the amount of body hair we had, and through vestigial bones like wisdom teeth, which we do not need anymore today. Wisdom teeth were likely used to chew raw meat, which we do not do anymore.
C. Chimpanzees are our closest living relatives on the planet, with 99% of our DNA being the same.

Hey there!
The answer would be ultrasound.
The ultrasound is considered safe because it uses sound waves for the detection of tissue, organ, baby etc. These waves are considered safe and transfer only a small amount of heat to the tissue in which the ultrasound is done. A little amount of heat is not at all harmful to the body in any means. Early defects of baby can be detected through this procedure, the merits of the process is much higher than its demerits.
Hope this helps !
Answer:
A combination of polypeptides and modified sugars that enclose the entire eubacteria.
Explanation:
A component of bacterial cell walls called peptidoglycan (PGN) promotes innate immune responses. Peptidoglycan, a polymer made of sugars and amino acids, creates the cell wall of the majority of bacteria by producing a layer that resembles a mesh outside the plasma membrane. N-acetylglucosamine and N-acetylmuramic acid residues are alternated in the sugar component. forms a saccules in the cell wall of most bacteria that resembles a bag. It controls bacterial cell shape and is crucial for osmotic stability. A heteropolymer made up of glycan strands carrying small peptides is known as a peptidoglycan.
