Answer: During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
Explanation:
Which pair includes a phase of the cell cycle and a cellular process that
occurs during that phase?

. It's very rare for someone with two X chromosomes to have DMD. Explain how a person with two X chromosomes could have the symptoms of DMD using what you know about inheritance and random mutation.
Answer: Duchenne muscular dystrophy (DMD) is inherited through X-linked recessive inheritance mode. It is characterized by muscle weakness which mostly affect boys. It can only affect girls when a female carrier got married to affected male.
Explanation: In the union between a carrier female and an affected male, four types of gametes will be produced as shown in the attached image. After fertilization, the resulting offsprings will consist of female carrier, normal male, female affected and male affected each with 25% probability. See attached image for better illustration.
X-linked recessive traits have the following characteristics;
1. More males are affected than females.
2. Approximately ½ of a carrier mother's sons are affected.
3. It is never passed from father to son.
4. All daughters of affected fathers are carrier.

How is it that every living organism has specialized cells that contain genetic material made up of only four different bases, yet every organism is different?
Answer:
See the answer below
Explanation:
The answer lies mainly in the genetic codes which are translated differently in different organisms.
The genetic code degenerates such that 64 possible codons from the four bases ([tex]4^3[/tex]) codes for the 20 amino acids that are available in nature. The transfer RNA is primarily responsible for the translation of the genetic codes and different organisms have different transfer RNA. Hence, the same genetic codes are differently translated in different organisms and this ensures that organisms are different.

The diagram attached shows the X chromosomes in a female fruit fly and the X and Y chromosomes in a male fruit fly. The two fruit flies are crossed with each other. Fill in the two chromosomes illustrating the female offspring of the fruit flies.
Answer:
See image attached.
Explanation:
We can differentiate the X chromosomes by calling the X chromosomes from the female [tex]X^f[/tex] and the X chromosome from the male [tex]X^m[/tex].
Then, we can take these pairs of chromosomes and cross them over in a Punnett square to find the possible offspring chromosome pairs.
We have for the female fruit fly:
[tex]X^f X^f[/tex]We have for the male fruit fly:
[tex]X^m Y[/tex]Create a Punnett square with the female's chromosomes on top and the male's chromosomes on the left.
[tex]\begin{array}{c|c|c|} \multicolumn{1}{c}{} & \multicolumn{1}{c}{\textbf{X}^\textbf{f}} & \multicolumn{1}{c}{\textbf{X}^\textbf{f}} \\ \cline{2-3} \textbf{X}^\textbf{m} & \text{X}^\text{f} \text{X}^\text{m} & \text{X}^\text{f} \text{X}^\text{m} \\ \cline{2-3} \textbf{Y} & \text{X}^\text{f} \text{Y} & \text{X}^\text{f} \text{Y} \\ \cline{2-3}\end{array}[/tex]After crossing over, we can see that there are two pairs of chromosomes inside the Punnett square.
These are the possible combinations of chromosomes for the offspring of the male and female fruit fly.
Using previous knowledge, we know that females have two X chromosomes and males have one X and one Y chromosome.
Since the question wants the chromosomes for the female offspring, we will use the two X chromosomes: [tex]$X^f X^m[/tex].
The female chromosomes have two bold lines, as shown in the diagram. The male X chromosome has 2 skinny lines.
Therefore, when filling the chromosomes that illustrate the female offspring, we will fill the left chromosome ([tex]X^f[/tex]) with two bold lines, and the right chromosome ([tex]X^m[/tex]) with two skinny lines.
Attached is an image of what the chromosome pair for the female offspring should look like.

can a unicellular organism get diabetes
Answer:
I don't think unicellular organisms can get diabetes.
Explanation:
Due to their small size, they are simpler to adjust to environmental changes like heat and cold. Unable to expand much. They are unambiguous organisms and may reproduce swiftly.
What disease causing agents in unicellular organism?Bacteria, protists, fungus, algae, and other unicellular organisms are all susceptible to attack by viruses.
When a bacterium is infected, a virus called a bacteriophage, which is smaller than the bacterium and uses it as a host during the T4 cycle to reproduce and flourish, is responsible.
Therefore, unicellular organism get infected with pathogen like virus but having less chance to get disease like diabetes.

which area of the North American continent would have the greatest risk of earthquake damage?
Answer:
The area is California.
Explanation:
There are 500,000 seismic tremors occurring out of which most of them are in the California zone. Over 80% of seismic tremors happen in a territory known as the Pacific Ring of Fire, a 25,000-mile horseshoe shape along the north side of the Pacific Ocean.
The principle purpose behind the distinction is that the California coast is directly over the limit of two of the structural plates that make up the Earth's covering.
Earth's covering, the lithosphere, is separated into in excess of twelve strong plates that buoy over a progressively gooey layer of hot shake.
In California, plates are granulating against one another. Envision striking two blocks against each other, often as possible reason them to split, perhaps severing lumps. As increasingly more weight is included, the block is probably going to break someplace in the center.
