Darwin's finches are often used to illustrate evolution. Evaluate the finch beaks shown in the picture. Choose ALL of the statem

ents that correctly explain the evolution of finch beaks.
A) As the environment changed, the finches grew longer beaks to allow them to get food out of fruits.

B) Finches with longer beaks settled on the same island with smaller beaked birds. Over time, they bred, producing medium beaked birds that became more common in the population.

C) There are finches with different types of beaks in the population. During a drought, those with shorter beaks are not able to find sufficient food and die, leaving them unable to reproduce and pass the trait on to offspring.

D) A random mutation introduced the shorter, thicker beak into the population. However, those with thinner, longer beaks were better able to get nectar from the island's flowers. Those birds with the shorter, thicker beaks were unable to get enough food to survive.

E) A disease swept through the island killing many of the insects that were common on the island, leaving the birds who ate insects from the ground starving. The finches that had thicker beaks and could get food from tree bark were able to continue to survive and reproduce, increasing this trait in the population.

Consider the cooling curve above. The substance is changing state from a gas to a liquid to a solid. As the temperature changes
Anni [7]

Answer: B)  there is a decrease in kinetic energy and the molecules get closer together.

Explanation: Kinetic energy is directly proportional to temperature, thus as temperature decreases, kinetic energy also decreases.

Gas is the state of matter in which particles are very loosely bound and hence can easily move past one another very easily and have highest kinetic energy.

Liquid is the state of matter in which particles are loosely bound and hence can move past one another easily and have high kinetic energy.

Solid is the state of matter in which particles are tightly bound and hence can not move easily and have low kinetic energy.

Thus on moving from gaseous to solid state, the kinetic energy decreases and the molecules get closer together.

Discuss the importance of a balanced diet.​
Aliun [14]

Answer:

u need a healthy diet cause it gives u the nutrients and energy u need to survive. ur body is more prone to disease n infections if u dont have a balanced diet. immune system weakens if u eat nutrient-poor foods. also here's something i copy-pasted from a random website:

A group of scientists is studying the internal parts of a cell. Which microscope is most appropriate for these scientists to use
Lady bird [3.3K]
The most appropriate microscope for studying the internal parts of the cell is ELECTRON MICROSCOPE. The correct option is B.
Electron microscope, which is a compound microscope is usually used to study the internal environment  of the cell because of the easiness with which one can easily distinguish the cell organelles from one another. Electron microscope gives great clarification of the cellular components and allow scientists to observe minute details about cellular structures. Electron microscope usually magnify specimens to one million times of their real sizes.
