4) If a dead organism is preserved as a fossil, which body tissues are most likely to survive? Why?
IrinaVladis [17]
The answer is hard tissue.

Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue (organs, skin, etc.). Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues.

True or false. Is sympatric speciation, a physical barrier arises and separates two populations l, ending flow between them
timofeeve [1]
<h3><u>Answer;</u></h3>

The above statement is <u>False </u>

<h3><u>Explanation;</u></h3>
  • Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
  • <em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
  • In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.
