Answer:
What is the difference between Metaphase 1 and Metaphase 2? In Metaphase I, the 'pairs of chromosomes' are arranged on the Metaphase plate while, in the Metaphase II, the 'chromosomes' are arranged on the metaphase plate. In Metaphase I, the spindle fibers get attached to two centromeres of each homologous chromosome.
In metaphase 1 the pairs of chromosomes referred to as bivalents are totally condensed. Moreover the in metaphase 1 of meiosis there is no centromere division whereas in metaphase of mitosis it does. They align on the metaphase plate in between the poles.

The porcupine is a rodent with an unusual trait. Porcupines have sharp spines or quills that help protect it against its predators. This trait is different from other rodents because of its needle like quills. This animal is also similar to that of a hedgehogs.
Answer:
A frameshift mutation can be described as a genetic mutation in which a single nucleotide or more than one nucleotide is inserted or deleted from the sequence of the DNA. As the gene expresses itself in the form of triplets of a genetic code, insertion or deletion can cause devastating changes in the genetic code due to which wrong proteins will be synthesized.
Frameshift mutations can be more noticeable than the substitution mutation. In a substitution mutation, only one of the nucleotides is shifted with another. The entire genetic code is not affected by it.
