What needs to happen for dominant traits to be observed in an organism?
Answer:
The organism's parents have to either be heterogeneous dominant or homogeneous.
Explanation:
When the traits get passed down they either have to have 2 dominant traits or a mix.
What types of organisms carry out respiration
Eukaryotes, including all multicellular organisms and some single-celled organisms, use aerobic respiration to produce energy.
Prokaryotic organisms such as bacteria and archaebacteria can use other forms of respiration, which are somewhat less efficient.

. 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.

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.

Open the color vison simulation and select Single Bulb. Click the button to turn on the flashlight, and toggle the filter switch to add a filter in front of the flashlight. Adjust the Filter Color and Bulb Color sliders to change the light color and the filter color, and observe what color the eye perceives. What happened when you used a colored filter and a colored lightbulb? Using your knowledge of the human eye, explain why this happened.
Answer:
The person in the simulation could see the colored light only if it passed through a filter of the same color. This filtering of color occurred because the filter absorbs the other colors. The filter lets light that’s the same color as the filter pass through, allowing the person to see that color.
Explanation:
This is the exact answer you might want to change it up just in case so you dont get into trouble.
The person in the simulation can only perceive the accurate color when it has been passed through a color filter which removes other colors.
Color filtersWe know that visible light is composed of several wavelengths. The wavelength that we perceive is dependent on several factors.
In this case, the person in the simulation can only perceive the accurate color when it has been passed through a color filter which removes other colors.

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.

(BRAINLIEST FOR CORRECT FAST ANSWER!!!) Look at each of the thirteen primates and determine the following. Which is the largest? Which is the smallest? How many have tails? Which ones have the largest eyes relative to body size?
The gibbon is not a monkey. They are considered lesser apes since they are smaller than great apes yet are members of the ape family.
What similarities primates share among together?Although the anatomy of the noses of lemurs and tarsiers are similar, lemurs have a material behind their irises that reflects light, whereas tarsiers don't.
Primates share genetic traits since they are linked to one another. In general, chimpanzees and bonobos, who are the closest living cousins of humans, share roughly 99% of human DNA with our most distant ape ancestors.
Baboons always live on the ground, unlike monkeys, which can either be terrestrial or arboreal. Not all monkeys have a long muzzle like a dog, only baboons do.
Therefore, The same characteristics apply to monkeys. Tarsier skulls have similar olfactory and visual characteristics to monkey skulls.

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.
