The correct answer is A. A burst of speciation
Explanation:
Adaptative radiation is part of evolution and occurs when a single organism or species diversify into a wide range of species (speciation), this process is called "adaptative" because the speciation occurs due to changes in the environment that make challenging survival usually due to the reduction of resources available and therefore organisms change to adapt to new conditions. Additionally, in adaptive radiation, the new organisms share traits with their common ancestor but also have different and unique traits. Considering this, it can be concluded adaptative radiation a burst of speciation.
When an organism reproduces they pass on their genetic information in the DNA to their<span> offspring.

Phospholipids are the lipids are the main constituents of the cellular membrane. The phospholipids; sphingolipids, and phosphatidylcholine are the two foremost lipids of the membranes. Phospholipids help in maintaining the integrity and fluidity of the membranes.
The answer is C. This was
achieved through
gene regulatory networks. The ability of the cells
to segment and differentiate gave the
metazoans a great advantage. This is thought
to have begun in the Cambrian period with complete
bodies existing by the Paleozoic era.
