What do you need help with ? I don’t see anything
Answer:
Index fossil that is also known as indicator fossil is used to determine the age of the layers of the rocks. It says that the new layer of sedimentary rocks lie over the old layer.
The deeper we go, the older the rocks we will find. Index fossil of animals that lived or survived only for a short period of time are very useful. An example of index fossil can be Ammonites that were found in Mesozoic era that was about 25-35 million years ago.
Hi there!
Magma is the same as lava, but just inside of the volcano before it is spewed out. (Lava is when it is spewed out.) They are basically the same thing (just different terms to describe it.)
Hope this helps!
Answer:
The correct answer is - Methionine, serine, histidine, aspartate, glycine
Explanation:
The new segment of DNA is: 3'-TACAGGGTGCTACCCACT-5', which performs two processes to form a peptide chain, transcription, and translation. In transcription, the DNA segment is encoded to an mRNA molecule which has its complementary sequence to DNA sequence.
New DNA strand: 3'-TACAGGGTGCTACCCACT-5'
mRNA sequence: 3'-AUGUCCCACGAUGGGUGA-5'
The translation of this mRNA would be on the basis of chart
AUG - Methionine (start codon)
UCC - serine
CAC - histidine
GAU - aspartate
GGG - glycine
UGA - stop codon
The peptide chain would be - Methionine, serine, histidine, aspartate, glycine
Explanation:
Answer: The higher animals needs and internal transport system so that the innermost cells can get nutrition which cannot be left on diffusion and osmosis to transmit. They also needed an internal transport system and so that they get oxygen to the internal cell...
