Answer:

Genetic variation

Explanation:

Darwin studied that different populations of finches on Galapagos island that are descended from the same species. Some species are evolved to eat nuts and large seed, some eat small seeds and some feed on insects and nectar.

So genetic variation occurred in different populations of finches which enabled them to bring changes in their beak according to the food resource they have chosen to feed on.  

So in Darwin's finches, genetic variation leads to new species which is a type of natural selection. Therefore subset of finches that can feed on large seeds and small seeds is an example of genetic variation.

Murljashka [212]

Answer:

Food webs either start with producers on<u><em> land </em></u>or with producers in <u><em>water</em></u>.

They are mostly plants or other producers like algae. Both aquatic and land food chains or food webs will start with a producer. An aquatic food web will generally start with a producer present in water. A land food web will mostly start with a producer from the land.

An insulating plate, such as plastic, tends to be positively charged when rubbed with cloth due to the piezoelectric effect. This phenomenon involves certain materials to generate charged particles as a response to mechanical stress applied to it. In this case, the mechanical stress was due to the rubbing motion.

What's the role of ATP in the muscle cell?
Drupady [299]

Answer: ATP is responsible for cocking (pulling back) the myosin head, ready for another cycle. When it binds to the myosin head, it causes the cross bridge between actin and myosin to detach. ATP then provides the energy to pull the myosin back, by hydrolysing to ADP + Pi.
