The Cambrian Explosion is when diverse animals were first recorded as fossils.
Explanation:
The fruits protect the seeds enclosed in the ovary. The seeds mature in the fruit by taking essential requirements.
The mature seeds retain the capacity of germination for a long period. It may be dispersed individually or along with the fruits to long distances by different agencies. The seeds germinate in the favorable conditions.
These are the advantages of fruits and seeds in the Angiosperms. These advantages help the spread of the Angiosperms in different climatic conditions. Thank you
Answer: <span>A) Slow to repopulate
------
Genetic variation is an advantage of sexual reproduction. It increases survival and the ability to adapt in a species. Species with genetic variation can respond better to environment changes, since the genetic variability allows some to be immune to disease or adapt better to a change, and live to reproduce.
Slow to repopulate is a disadvantage because the species cannot recover quickly after a large disaster. It also means they cannot adapt as quickly to an environmental change.</span>
Mutation ( that’s what I put )
Answer:
Neurilemma
Explanation:
Schwann cells are the neuroglia that produces myelin sheaths. There is a formation of multiple layers of the glial plasma membrane around axons. The cytoplasm and nucleus of Schwann cells from the outermost layer while the inner part has multiple layers of the Schwann cell membrane. The outer nucleated cytoplasmic layer of the Schwann cell that encloses the myelin sheath is called neurolemma. It is found only around axons in the PNS. Its function is to serve in the regeneration of injured axons by the formation of a regeneration tube.
