I would say C but In the integumentary system there are four main tissue types, those are Epithelial, Connective, Nervous and Muscular tissue
Answer:
A) Phanerozoic
Explanation:
In the given question, the chart about the evolution of insects has not been provided but based on the previous knowledge, this question can be answered.
The geologists have divided the time scale into many variables in which Eon represent the longest time scale period which has lasted for the millions of year.
The Phanerozoic eon represents the time scale during which first visible life evolved and began around 542 million years ago and is present until today. The insects belong to the arthropod group which evolved during a smaller time scale called Devonian period.
Since the insects evolved around 479 million years ago which falls under the Phanerozoic eon, therefore, phanerozoic is the correct answer.
Thus, Option-A is correct.
<u>Answer</u>:
No, speciation doesn’t occur in specific characteristics and predictable manner.
<u>Explanation</u>:
Speciation means creation of a new kind of plant or animal. When a particular species separates from its members of species and develops its own characteristics, speciation occurs.
There are different types of Speciation. In allopatric speciation, species separate due to geographical conditions like waterways or mountain range and evolve into separate species. Whereas in Sympatric speciation, species evolve into separate ones without any change in geographical conditions. Other types of speciation are artificial, peripatric and parapatric type of speciation. So, these changes are neither specific nor predictable.
