The correct answer should be
<span>D. Autonomic nervous system

It is called autonomic because it works on its own and it regulates organs functioning which is a thing that happens involuntarily. It regulates heart beats for example and it's not something that you do voluntarily since the heart beats regardless of you. It also controls things like vomiting or sneezing that you can't choose not to do when it starts happening.</span>

Peter and Rosemary Grant observed a small group of the large ground finches that colonized Daphne Major in the Galápagos Islands
erica [24]

Answer:

1) Founder effect and genetic drift: Small colonizing population did not represent the original gene pool of the source population and was more likely to undergo genetic drift.

2) Natural selection

Explanation:

Evolution of the population of the finches with larger beaks might have occurred due to one of the following mechanisms:

a) Founder effect and genetic drift: Since the size of the colonizing population was small, it did not carry all the genes and their alleles present in the gene pool of the original population. The small population size made it more likely to evolve by any chance event.  

b) Natural selection: The availability of different food types in the new habitat led to the natural selection of the larger beaks as the finches with larger beaks might have been able to better exploit the available food resources.

Explain how the fluid mosaic model accounts for the observed properties of cellular membranes
Zinaida [17]

 The mosaic nature is due to the numerous proteins that are entrenched in the phospholipids bilayer, fluctuate in shape, size and patterns in the same way as the stones or tiles of a mosaic. 


the flexibility is due to individual phospholipids molecules which can move virtual to one another and gives the membrane a flexible structure that is constantly changing shape

hope it helps
