Answer:

2.5 billion years ago.

Explanation:

Evolutionary tree is constructed to understand the phylogeny and evolution relationship of the organism. The evolutionary tree is constructed by looking at the molecular and physiology of the different organisms.

The eukaryotes are more closely related to the archaea. Depending on the biochamical and molecular evidence is has been found that they share the common ancestor almost 2.5 billion years ago. This can also be deduced by the fossil evidence as well.

Answer:

The correct answer is - 2.5 billion years ago.

Explanation:

The life on the earth has evolved with 3 different lineage namely Bacteria, Eukarya, and Archaea. However the 2 are prokaryotic groups of microbes that lack membrane bound organelles and nuclei.

IceJOKER [234]

Answer:

from the splitting of water molecule.

Explanation:

The splitting of water molecules  by sunlight is called Photolysis. This is the first reaction in photosynthesis; which occurs by catalysis  of enzymes of Photo system 11.

It involves the splitting of water molecules into;

hydrogen ion/protons.

Oxygen

and electron.

<u> Oxygen is  the by product liberated into the atmosphere, for animals to inhale for the process of cellular respiration</u><u>.</u>This is the source of oxygen fro cellular respiration in animals.

the hydrogen ions combined with electrons from photosystem 1 to reduce NADP .The latter is used to reduce C02  to form carbohydrate in light independent reaction

If the part of our skin we can see is made of dead cells,<br> why is it painful to get a tattoo?
Nat2105 [25]

Answer:

Well, it’s because tattoos have to get that ink deep enough that it won’t get washed away but not too deep so it remains visible — the ideal location ends up being right next to your skin’s pain receptors.

slava [35]

Answer:

The H1N1 virus replicates quickly.

Explanation:

The H1N1 virus replicates quickly, which is why it is of high importance that an antiviral agent is administrated within the first 48 hours so that the reproduction rate of the virus can be lowered, resulting in an effective treatment against H1N1 flu. In other words, by administrating an antiviral in the first 48 hours, we are helping the body to fight the virus since the antiviral stops the reproduction of it, and we increase the chances of succeeding at it.
