Answer:
1 Adult ticket=$35
1 Children ticket=$20
Step-by-step explanation:
21C+15A=945
6C+6A=330
we find adult tickets first
42C+30A=1890
42C+42A=2310
12A=420
A=35
we will find children ticket next
42c+30a=1890
30c+30a=1650
12c=240
C=20

Precipitation of ribosomes and RNA is "None of the options are correct. So Precipitation of ribosomes and RNA does not produce any of the inclusions listed.
<h3>What is
Precipitation of ribosomes?</h3>
Heinz bodies are aggregates of denatured hemoglobin that form in red blood cells due to oxidative stress. They are seen in conditions such as glucose-6-phosphate dehydrogenase deficiency, thalassemia, and some drugs.
Howell-Jolly bodies are remnants of nuclear DNA that are normally removed from red blood cells by the spleen. They are seen in conditions such as asplenia, hyposplenia, megaloblastic anemia, and hemolytic anemia.
Therefore, Auer rods are cytoplasmic inclusions that contain granules of myeloperoxidase and other enzymes. They are seen in malignant white blood cells, especially in acute myeloid leukemia."

The two passages have the theme "time erases everything," as shown in the first answer option.
We can arrive at this answer because:
- The passage from the poem "Ozymandias," shows how all the glory, wealth, and magnificence of a great leader fades over time.
- In this poem, we can see that someone seen as the king of kings, can have all his power terminated and buried in the sand.
- In "On Seeing the Elgin Marbles," we can see how memorable moments pass and become memories of "the old days," even though it seems like it will last forever.
In this case, we can see that the two poems reinforce the idea that everything is fleeting, and that time brings the end of all things.
The two passages the question refers to can be seen in the image below.

The ability to generalize a study's results to different circumstances is known as external validity that suffers from 7 types of threats.
<h3>What are the threats to External Validity?</h3>
There are 7 major threats to external validity.
- The first threat is sampling bias, in which a sample is not representative of the population.
- The second threat is history, where an unrelated incident can affect the results.
- The third threat is observer bias, in which the traits or actions of the experimenter unintentionally affect the results, resulting in bias and other demand features.
- The fourth threat is the Hawthorne effect, which describes the propensity for individuals to alter their behaviour merely because they are aware that they are being observed.
- The fifth threat is the Testing Effect, in which the results are impacted by whether a test is administered before or after another.
- The sixth threat is the aptitude-treatment, which involves the interaction of individual and group factors to affect the dependent variable.
- The environment, time of day, location, researcher traits, and other variables that restrict the generalizability of the results are included in the seventh threat.
