The allele combination XRXr represents a female who is a carrier for an X-linked recessive disorder.
X-linked recessive inheritanceFemales usually inherit two chromosomes X, while men inherit only one chromosome X (and one chromosome Y).
The inheritance of the chromosome X in females resembles mendelian inheritance because females have two X chromosomes.In this case, females having the genotype XRXr are carriers because lowercase letters denote the presence of the recessive allele.In conclusion, the allele combination XRXr represents a female who is a carrier for an X-linked recessive disorder.

You will need to create a blueprint to design your own Rube Goldberg device. Then, you will need to BUILD IT and complete each of the sections of the lab report (provided later). Your Rube Goldberg device design must include:
A task you are looking to accomplish at the end (ex: turning on a light, opening the fridge, etc)
at least 6 stages
at least four energy transformations to perform a simple task (ex: kinetic, potential, chemical energy, radiant energy, sound energy, electrical energy, thermal energy, magnetic, etc)
Part One: Draw It
If you draw your device, you will need to turn in your device design along with a written description of how each step works. You may choose to draw it freehand and scan or photograph the drawing, or you may use a computer program to digitally create your device. You can either write a description down in a box at each stage on the drawing OR submit the written descriptions separately. Insert below, if possible.

Explanation:
In today's world, a phone call to 911 is designed to ensure that emergency services, including fire, law enforcement, and emergency medical care is accessible to all individuals who find themselves in an emergency. Traffic laws establish that drivers are to move their vehicles to the right of the road and come to a stop in order to allow an emergency vehicle to pass. Emergency medical care is recognized as vital to helping to keep people safe and healthy. Yet, emergency medical services (EMS), as we know them today were only formally established in United States the 1970s. How did the country survive for so long without these services? What did citizens do if they had an emergency? What changes took place that made EMS a part of the emergency care provided for citizens? In this chapter, you will learn about the history and development of EMS in the United States.
OBJECTIVES

in humans, normal people are dominant (X) to people with x-ray vision. If a mutant with x-ray vision has a child with a woman heterozygous for x-ray vision what is the chance that one of their children will have x-ray vision?
Answer:
2/4 or 50%
Explanation:
Heterozygous means the organism has two different alleles, so the genotype of the woman is Xx
The mutant's genotype is xx, because in order for a recessive trait to be expressed, there needs to be two recessive alles
Use the genotypes of the parents to create a punnett square (shown in image) to find the possible genotypes of their children
To chance of a phenotype is determined by how many of the possible genotypes will express the phenotype of x-ray vision and how many genotypes there are in total. The chance can be presented like this:
2/4
2 is the number of x-ray children
4 is the total number of children
To find the percentage you can do 2 ÷ 4 × 100
And that will give you the answer of 50
So the percentage is 50%

Emma and her younger brother were running a race. After 30 minutes, Emma started feeling pain in her lower leg muscles. a. Suggest the reason for this.
Answer:
This is due to lactic acid accumulation in Emma's leg muscles.
Explanation:
In the absence of oxygen in the muscle cells, the cell switches from performing aerobic respiration to lactic acid fermentation. The lactic acid fermentation produces lactic acid as a product, which builds up in the muscle cells of the body causing a burning sensation and pain. This often happens during exercises.
This is the cause of Emma's pain in her lower leg muscles. Lactic acid has been formed and accumulated in the muscle cells of her leg during the exercise with her brother.

How do the organ systems function together in the human body?
Answer:
Some body systems work together to complete a job. For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it. Some body systems share a common organ that performs more than one job.
