Answer:a
a possible explanation for this occurrence is that a test tube or dropper was accidentally used repeatedly without being sterilized, causing sample cross-contamination. DNA in this test case did not confirm that the father of the second child was another client of the fertility clinic who had never met the mother...therefore this is a possibility.

The yellow beams in the model represent equal amounts of radiation coming from the Sun. Based on the information shown in the model, which two statements are true?
Answer:
B. All parts of the Earth's surface get the sunlight atbthe assume angle and of the same intensity
C. The regions near the poles get the most-intense and most-direct sunlight
Note: Then model and options are found innthe attachment below.
Explanation:
Latitude is the distance north or south of the Equator. It’s measured in degrees, from 0° to 90°. The amount of sunlight received and hence, the temperature of a place varies with latitude. The higher the latitude of a place or region, the lower the temperature of that region or place will be.
The elliptical shape of the earth contributes to how the heat from the Sun is received by a place. At the Equator, the Sun’s rays are most direct and intense, hence, the temperature of regions around the equator is highest.
At higher latitudes which have more curved surfaces, the Sun’s rays are less direct. Thus, the temperature of a place decreases with increase in latitude due to the less-direct heating by the Sun.
At the poles, the Sun’s rays are least-direct and least-intense. Temperature is lowest at the poles. That is why polar regions are covered with ice.
From the model and the options given, options A and D are correct while options B and C are false.

What's something you liked or found interesting about any one of the episodes of the aquarium? (Make sure to write at least 4 sentence).
Answer:
An interesting episode of the aquarium I had was seeing a dolphin show. The dolphin was super smart, and I have to admit it was smarter than me. I mean I was like 3 when I went there so, I guess that is normal? Anyways, the dolphin was doing cool tricks like twist jumping, and even I tried it but failed. The dolphin went to the worker when the worker called its name. I learned that day that you shouldn't underestimate dolphins because they are smart.

Compare the results of the Unknown Explain the identity of the Unknown using your experimental results in the exercises to help explain and support your answer.
Question
The question is incomplete. The complete question is as follows:
Review the Data Tables in Exercises 1 and 2. Compare the results of the Unknown for all tests to the results for the various known samples to determine the identity of the Unknown. Explain the identity of the Unknown using your experiment results in the exercises to help explain and support your answer.
Answer:
According to the results, the unknown is a protein.
Explanation:
According to the results, the unknown is a protein, not a carbohydrate or lipid. When Biuret's reagent test is performed, it tested positive while the tests for sugar, starch, and lipid were negative proving that the unknown substance is the protien.
Explain the process of when a wave occurs.
Science PLZ HELP
Answer:
energy passing through the water, causing it to move in a circular motion. When a wave encounters a surface object, the object appears to lurch forward and upward with the wave, but then falls down and back in an orbital rotation as the wave continues by, ending up in the same position as before the wave came by.
Explanation:
Answer:
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. The gravitational pull of the sun and moon on the earth also causes waves.

what are the feeding habits of an earthworm?
~(✿^‿^)~ helo pls
Answer:
Earthworms enhance the soil by their burrowing and feeding habits. Earthworms basically eat their way through the soil, and they have a tremendous ability to process the dirt they live in. Some studies suggest that in one acre of top soil, earthworms consume and mix more than 20 to 40 tons of soil per year.

if perimeter of a square is 24cm find its area please give me easy formula
Answer:
4l = 24
so l=6
now
l*l =6*6
= 36 square cm
Answer:
36cm²
Explanation:
Perimeter of a square = 4x (sum of all 4 sides)
Perimeter = 24 cm (given)
[tex]\implies [/tex]4x = 24
x = 24/4 = 6 cm
Now, area of a square = (side)²
Area = (6)²
= 36 cm²

Which statement is true regarding type 1 diabetes?
1. Type 1 diabetics are considered insulin-dependent diabetics.
2. Type I diabetics acquire the condition later in life.
3. Obesity is a cause of Type 1 diabetes.
4. Type I diabetics can control their diabetes with diet and exercise.
Answer:
option 1- type 1 are considered insulin dependent
Explanation:
the other options all describe type 2
Answer:
1. Type 1 diabetics are considered insulin-dependent diabetics.
Explanation:
Type 2 diabetes acquires later in life not Type 1.
Type 1 diabetes is thought to be caused by an autoimmune reaction (the body attacks itself by mistake) that destroys the cells in the pancreas that make insulin, called beta cells. This process can go on for months or years before any symptoms appear
Type 2 control with diet and exersize while as Type 1 is controlled by insulin.

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms, including a high fever, headaches, and body aches, typically occur two to seven days after infection by the virus. This information suggests that the reproductive cycle of the SARS virus is - lysogenic, because the virus is a coronavirus. lysogenic, because the virus is a coronavirus. lysogenic, because the virus primarily affects older people. lysogenic, because the virus primarily affects older people. lytic, because the virus causes respiratory illness. lytic, because the virus causes respiratory illness. lytic, because of the quick onset of symptoms after infection.
Answer:
lytic, because of the quick onset of symptoms after infection
Explanation:
As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.
The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.
Answer:
lytic, because of the quick onset of symptoms after infection
