Answer:
Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships.
Explanation:
Basically it is a hypothesis from before hypothesis actually were called hypothesis
Answer and explanation:
Gram positive bacteria :
1) They retain crystal violet stain thus staining purple
2)They only produce exotoxins.
3)Peptidoglycan is thicker and multilayered
4)Techoic acids are present in their cell walls.
5)Lipopolysaccharides are absent in their cell wall.
6)No periplasmic space present
Gram negative bacteria :
1) They retain red safaranin stain thus stain pink.
2)They produce both exotoxins as well as endotoxins.
3)Peptidoglycan is thinner and single layered.
4)Techoic acids are absent in their cell walls.
5)Lipopolysaccharides are present in their cell wall.
6)Periplasmic space in present.
Scavengers are an organism that mostly consumes decaying biomass.
<span>
Detritivores feed on decaying organic matter and return essential nutrients back to the ecosystem.
So the answer would be (D). Both organisms feed on pieces of other dead organisms.</span>
Answer:
B
Explanation:
A could be brought to a customer service, but it would be a color the buyer chose. So it would be their fault.
C wouldn't be brought to a customer service, but even if it was they would have to talk to the manufacturer. Since the store carries items from the makers.
D wouldn't be brought in either.
Answer;
DNA or protein sequences of shared genes
The MOST accurate way to determine the evolutionary relationship between two animals is through the examination of DNA or protein sequences of shared genes.
Explanation;
DNA or protein sequences of shared genes. Biochemical evidence is extremely accurate in determining the relationship between two organisms. Many animals have been re-classified, due to DNA evidence.
