The answer is stem cells, they consist of classes of cells
that are undifferentiated and are able to be classified them into types like
specialized cells. They consist of having two main sources that will help them
develop and mature, these main sources are called the embryonic stem cell and
the adult stem cell.
Answer:
No, proteins don't carry out translation, ribosomes do.
And even if one considered the fact that ribosomes contain proteins (even though it is the ribosomal RNA part that links amino acids together in translation), it still would not be true that the variations in base sequence required more ribosomal proteins.

Answer:
The beginning of Cambrian period was about 541 million years ago and ends about 484.5 million years ago.
Explanation:
Cambrian period is a geographical period that appears in Paleozoic Era and lasts at Phanerozoic Eon to the beginning of Ordovician Period and the name was given as most of the sedimentary deposits were found at that period The majority of living organism includes unicellular or some multi cellular complex life forms.
Most live forms were aquatic and arthropods were the most dominant animals in the water that are known by studying the fossil records.The species adapt themselves to change with the environmental variations.
Animals like <em>Protichnites</em> and <em>Climactichnites</em> were found during this period.
The fossil records also suggested the presence of euthycarcinoides that are the extinct arthropod species.
Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.
