Answer: The main body of most fungi is made up of fine, branching, usually colourless threads called hyphae. Each fungus will have vast numbers of these hyphae, all intertwining to make up a tangled web called the mycelium.
Answer:
The correct answer is - speciation is sympatric.
Explanation:
Sympatric speciation is a process of speciation that takes place when there is reproductive isolation between two populations of a species without any geographical separation.
This speciation takes place in the population with come ancestors as given in the question both pods of dolphins lose their ability to interbreed due to the sympatric speciation without any geographical separation.
Thus, the correct answer is - speciation is sympatric.
Answer:
The correct answers are "The population of birds with large beaks will increase on the island" and "The trait for large beaks will be passed on to future generations through natural selection".
Explanation:
Natural selection functions under the premise of survival of the fittest, where stressful situations such as lack of resources will select the organisms with advantageous traits. In this case, the decrease on seeds affected particularly the numbers of small, soft seeds over large, hard seeds. This stressful situation will select the finches with the advantageous trait of having large beaks, because they are able to feed from large, hard seeds. This trait will be passed on to future generations through natural selection, which eventually will result in the population of birds with large beaks will increase on the island.
