8. What characteristics of a normal fault and a reverse fault can be used to easily tell them apart?
(9 points)

Answers

Answer 1

Answer:

Normal faults and reverse faults are two types of faults that occur in the Earth's crust. The main difference between these two faults is the direction of the movement of the hanging wall and the footwall. In a normal fault, the hanging wall moves downward relative to the footwall. In contrast, in a reverse fault, the hanging wall moves upward relative to the footwall. This difference in movement can be used to easily tell normal and reverse faults apart. Additionally, normal faults tend to occur in areas where the Earth's crust is being pulled apart, whereas reverse faults tend to occur in areas where the Earth's crust is being compressed or pushed together.

how are mutation and sexual reproduction involved in creating and maintaining variation in a population

Answers

Answer:

Mutation and sexual reproduction are two essential processes that contribute to creating and maintaining variation in a population.

Mutation is the ultimate source of genetic variation in a population. It is a random process that generates new alleles or genetic variations in an organism's DNA. Mutations can arise due to various factors such as exposure to radiation, chemicals, or errors during DNA replication. These mutations can be beneficial, harmful, or neutral, and they can change the physical traits of an individual.

Sexual reproduction involves the fusion of gametes from two parents to produce offspring that inherit traits from both parents. The process involves the mixing and recombination of genetic information from each parent, resulting in a unique combination of genes in the offspring. Sexual reproduction can introduce new genetic variations into the population and shuffle existing genetic variations, resulting in an increase in genetic diversity.

Both mutation and sexual reproduction work together to create and maintain genetic variation in a population. Mutations provide the raw material for genetic variation, while sexual reproduction shuffles and recombines this variation. The combination of these two processes leads to the creation of unique genetic combinations, which can help populations adapt to changing environmental conditions and evolve over time.

Because the modules need to be connected quickly once they reach his build site, Xavier wants to know if he can have them all delivered on the same day. Kevin says that this would be possible using one truck per module. The fee for transporting each module is 20 cents per truck per mile, plus the cost of fuel. The factory is 350 miles from Xaviers build site, and Kevin estimates that each truck will need $500 worth of gas.On your math sheet, complete the following problem to help Xavier find out how much he will spend on transportation costs:Math Problem 5: Calculate Xaviers transportation cost to have the modules delivered on the same dayUse this formula to calculate Xaviers cost:[(.20 miles)+500] number of modulesPart 2: Job BoardXavier is excited but knows this is a huge project.

To do this, you will be taking the answers to the math questions above and creating items that Xavier can hang on his job board to remind him of the choices he should make in this project. You may select to create your job board in poster form or digitally in a word processing document. Either way, the job board should include the following pieces of content:A rough drawing of Xaviers lot that includes the lot measurements provided above.Make sure that you include the total area of the lot that you calculated in Math Problem 1 somewhere on this drawing.A sketch of the prefabricated house option that you suggest Xavier purchases (either Option 1 or Option 2).Make sure that you include his final price that you calculated in Math Problem 3 or 4.Also, be sure to label the upgraded technology that was included in the option you chose so that Xavier can point it out to his building inspector when the time comes.A graphic representation (photo, clip art, etc.) of a truck with the final transportation cost on it (this is the answer to Math Problem 5).
