A vertebrate-animal embryo gives rise to the centrum. The centrum is a bone that is part of the vertebral column. It is the hollow space within the vertebra that protects and contains the spinal cord. Within this hollow area are several nerves that send impulses to the brain enabling the organism to function and be at its homeostasis.
The roots and the stem because it gets water and food to help it grow
The first is gene sequencing. This allows the sequence of nucleotides on DNA of different organisms to
be identified. The sequence is then compared the bigger the difference in this sequence,
the stranger the organisms are with regards to the evolutionary relationship.
<span>The second is
carbon dating. This enables anthropologists
to determine the age of fossils by calculating the time taken, in half-lives,
by particular elements to decay, such as carbon-14 </span>
Explanation:
Formed from the aggregation of abiotic components, protocells are the precursors of modern living cells. Despite not being alive, protocells show characteristics similar to those of biological cells.
