Vertebrate chordates differ from invertebrate chordates by the presence of the vertebral column.
<h3>Vertebrate vs invertebrate chordates</h3>
Chordates are of two groups - vertebrates and invertebrates.
The vertebrate chordates have vertebral columns which developed from the notochord.
The invertebrate chordates, even though possess notochords at some points in their life, do not have vertebral columns.
Vertebrate chordates include fishes, birds, reptiles, and mammals. Invertebrate chordates include the tunicates and the lancelets.

In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells, each with half the number of chromosomes as the original parent cell. The two meiotic divisions are known as meiosis I and meiosis II.
Answer:
Explanation:
As a microbiologist there are different methods are devised for characterization of microbes.such as Macroscopic analysis and microscopy method.
With the help of microscope the needed information about the individual cell such as individual cellular characteristics can be obtained, the magnification help to provide the features such as size, shape and motility of the microbes which helps to know the specific microbes characters.
When handling an unknown environmental microbe, with help of the cell characteristics of the microbes obtained using the microscope, the identity as well as metabolic characterization can be known such as the type of environment the microbes can survive in(aerobic or anaerobic), the source of food.
No growth was observed on the control plate.
The growth on the control plate indicates that the aseptic technique devised in the model was an adequate method for the prevention of the control plate from been contaminated.
Biosphere 2 was a tremendous success, Many people don't realize that hundreds of papers were written about it.
