How does the process of natural selection account for the diversity of organisms that Darwin observed on the Galapagos Islands?
Answer:
Since each island is very different, birds from each of these islands all have different beaks, colorations, and sizes depending on the natural environmental factors surrounding their island.
Explanation:
I would also add in how birds had to adapt with different beak lengths and sizes in order to be able to get the food type that was most abundant. Natural selection was abundant in this case if one food source (say small seeds) was scarce, a bird with a small beak 1. Had very little if no small seeds to eat and 2. If there were large nuts that required breaking open (ability with birds for larger beaks to do so), the small bird could not break them open and then would unfortunately probably starve to death. Thus, natural selection occured so the birds with the large beaks were able to carry on their traits while the birds with the small beaks did not have as great of an opportunity (if not opportunity) to carry on their traits.
Since each island is very different, birds from each of these islands all have different beaks, colorations, and sizes depending on the natural environmental factors surrounding their island.
Which has more genetic information, a body cell or a gamete? Explain your answer
The body cell has more genetic information. A gamete only has half the information of a body cell. So when two gametes combine (a sperm and an egg), together they provide the child with all the genetic information needed for its body cells.

A classmate explains that igneous rocks can be changed to metamorphic rock by first being melted into magma and then cooling. What correction needs to be made to this statement?
Answer:
Cooled magma becomes igneous rock
Explanation:
Took the quiz
Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.
What are rocks?There are three different types of rocks: metamorphic, sedimentary, and igneous. These rocks can all alter. In actuality, any rock may transform into any other kind of rock.
Condensation and cooling: The Earth's interior can experience temperatures hot enough to produce magma. Igneous rock is created as crystals develop in the cooling magma.
If the lava cools gradually, as it does if it stays inside the Earth for an extended period, the crystals enlarge. The crystals will be very tiny if the magma cools quickly. Crystallization is the process by which crystals emerge from magma.
Therefore, Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.

Explain the importance of CDK in the cell cycle
Answer: They are important because they help modify different proteins.
Explanation:
The importance of CDK in the cell cycle is that they are important because they help modify different proteins and CDK are important in the regulation of the cell cycle.
What are the importance of CDK?CDKs are important in many reasons as they help in the regulation of the cell cycle. They carry out their function by adding phosphate groups to target proteins. Protein kinases called CDKs (cyclin-dependent kinases) are involved in controlling the cell cycle. The regulatory proteins known as cyclins are responsible for activating the cyclin-dependent kinases. As the cell moves through the cell cycle, the activity of different Cdks rises and then falls.
A cyclin-Cdk complex is created when a particular CDK binds to the associated cyclin. Proteins and other targets are phosphorylated by cyclin-Cdk complexes. Some of these proteins are activated by phosphorylation whereas the others are deactivated. For instance, phosphorylation causes the protein p27 to be broken down. Since p27 is one of the main inhibitors of cell division, low levels of p27 cause cells that aren't dividing to start doing so.
Therefore, The importance of CDK in the cell cycle is that they are important because they help modify different proteins and CDK are important in the regulation of the cell cycle.

Why do candles extinguish when a lid is closed?
Answer:
fire needs oxygen to burn, when you take that oxygen away by putting a lid on it the fire goes out.

On Monday afternoon, Arun has keyboard practice session in his school auditorium. He crosses his school playground and enters the cool and dark auditorium. Initially he is unable to see anything. But after sometime he is able to make out the way between the rows of seats. During this time, in his eyes.
Answer:
The correct answer would be - pupils expand or become bigger so more light can enter the eyes.
Explanation:
When Arun crosses the playground he was in a warm and sunny condition where light is more than required so the pupil becomes small in an excess light condition.
So, that less light can enter the eyes and when he enters into a dark auditorium then less light enters in his eye and he can't see a thing and pupil expands and more light enters the eye enabling to see and able to make out the way between the rows of seats

According to the diagram below how are metamorphic rocks formed
A. Wastes deposited by plants and animals decompose and weather
B. Other rocks experience intense heat and pressure
C. Sand and other particles are buried,compacted, and cemented together
D. Molten rock cools and turns solid
When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some mixture of these conditions, metamorphic rocks are created. These kinds of conditions can be obtained deep within the planet or where plate tectonics collide.
What two processes result in metamorphic rocks?Heat and pressure cause an existing rock to change into a new rock, creating metamorphic rocks. When hot magma hits rock, contact metamorphism takes place. Under the intense heat and pressure produced by tectonic forces, regional metamorphism changes substantial portions of existing rocks.
Most metamorphic rocks are formed where?The majority of metamorphic rocks are formed underground. Extreme pressure and heat are used to produce them. This includes any procedure where heat, force, or the use of chemical fluids change the structure or makeup of a rock while it is still solid.
