Answer:

A. Some speculate that they were blown out to the islands by a massive storm

Explanation:

The common rosefinches are thought to have arrived on the Hawaii islands between 6 and 7 million years ago. As the common rosefinches are not big birds and they can not fly over very long distances, the scientists believe that it is a massive storm that blow some individuals to the Hawaii islands. This is nothing weird, as it has been witnessed numerous times how massive storms manage to carry some smaller birds to places where they are not able to fly on their own. Once there, the birds encountered suitable conditions for living and lot of open niches in the food chain. This resulted in quick diversification of the common rosefinches, with members of the species gradually adapting to a particular niche, experiencing changes to be more competent, and creating numerous new species after some time.

Answer:

A)Ocean floor evidence of sea floor spreading.

Explanation:

evidence pointing to the steps or process  of seafloor spreading and effective plate motion This theory was accepted by many scientist because  it depended  on hard evidence and could describe most of the modern geological structures such as ocean basins,

What is the tectonic theory?

The theory of plate tectonics plates  says  that Earth's surface is made of rigid slabs of rock, or plates, that move to each other.

What is a tectonic plate?

They are huge slabs of rock that cover the earths mantle When a earthquake occurs that's because the tectonic plate is breaking  that makes the ground shake  During the earthquake and afterward, the plates keep on shaking until they are stuck again!

3. jack is using plastic beads to model water molecules in each state of water. how shoule she the beads to represent water mole
just olya [345]

Jack should arrange the beads close together and slide past each other to represent water molecules in a liquid.

<h3>How are the molecules of water arranged when water is in its liquid phase?</h3>
  • Each water molecule contains two atoms of hydrogen and one atom of oxygen, arranged such that one side of the molecule (nearest the hydrogens) is positively charged while the other side (nearest the oxygen) is negatively charged.
  • They’re arranged randomly, and in random motion.
  • In fact, they’re not even keeping the same hydrogen atoms, as they are constantly popping off and reforming on the nanosecond time scale.

Hey!
8= B : adenine with thymine , guanine with cytosine.

9= False : its not single , *dual* helical structure.

10= Every humans' DNA is different but its as similar as our relatives' DNAs as far as i know so its False.

11 = The two backbones of the DNA molecule consists a deoxyribose sugar ^with 5 carbone^ and a phosphate so the correct answer is B

12= Procaryotes' Genomes are simpler- structured than eukaryotes' so procayotes DNA is 1/1000 of eukaryotes.I couldnt translate the options correctly (im not native sorry) but i think its B according to my knowledge of that XD

13= the amount of adenine, guanine, thymime and cytosine must be same so the correct option is %40as well.

Hope it helps!!!
