1. Basaltic magma is the hottest type of magma. Magma is the hot lava that comes from the eruption of volcanos, and its made of the liquid minerals that are found in the matle, the Earth's second layer after the crust. Basalt is one of the mineral that it is possible to find, and it happens to be one the hottest tupe of magma.

2. Two of the processes that move tectonic plates over the surface of the Earth are ridge push and slab pull. The Earth is not a static object. it has its own balance and equilibrium and the crust upon which we are is always changing and moving. two of the processes that are involved in the destruction of old crust and making of new one are ridge push and slab pull.

3. The longest continuous mountain ranges on Earth is located in the Western portion of the United States. While it is true that it is possible to find longer mountain ranges all around the world, the one locate in the western portion of the usa is the longest continuous, menaning there is no breaking from one mountain to the other.
B) Different species share the same space.
C) A population is divided.
D) A major change on earth takes place.
2. Which of the following must be true of their individuals if two populations are no longer the same species?
A) They do not have any of the same genes.
B) They do not share any of the same space.
C) They do not resemble each other at all.
D) They cannot reproduce successfully with each other.
3. How does speciation start to take place on a genetic level between two isolated populations?
A) Large numbers of mutations occur.
B) Allele frequencies change in different ways.
C) New genes are added to one group.
D) Recessive alleles become dominant.
The 3rd question is actually B. Allele frequencies change in different ways
The answer is; The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them
The closer together two genes are on a chromosome, the higher the likelihood that they will be inherited together. This is referred to as genetic linkage. The higher the genetic linkage the lower the recombination frequency of the two genes.
The statement that 'The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them' is true regarding linkage. This is because genes close together are less likely to be separated during crossover in meiosis. Other statements provided about linkage are typically incorrect.
In the context of genetics, linkage refers to the phenomenon where genes that are located nearby each other on the same chromosome tend to be inherited together. Therefore, the correct statement regarding linkage from the provided options is:
The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them.
This is because when genes are close together, they are less likely to be separated during crossover, a process that occurs during meiosis.
Note that not all traits that Mendel studied are due to genes linked on the same chromosome. Most genes are in fact not linked - they can independently assort during meiosis. Equally, linked genes are not found on different chromosomes, they are on the same one.
Lastly, the recombination frequency for two genes that are far apart from each other doesn't have a maximum of 100%. It typically peaks around 50%, which is an indication that the genes behave as if they are independently assorting.
