write detail note on malaria 2 study
A detailed note on the malaria is discussed below:
What is malaria?A parasite that frequently infects a particular species of mosquito that feeds on people can result in the serious and occasionally fatal disease known as malaria. Malaria often causes severe disease, including high fevers, shivering chills, and flu-like symptoms. Humans can contract four different types of malaria parasites: Falciparum Plasmodium, P.
Female Anopheles mosquitoes carrying the Plasmodium parasite bite people to feed their own eggs, which is how the parasite is propagated. An infected mosquito injects sporozoites, or early stages of the parasite, into the host's bloodstream while it consumes its prey (often between twilight and sunrise). The sporozoites are transported by the blood to the liver, where they develop into schizonts, which are a type of parasite. Each schizont multiplies into thousands of merozoites throughout the course of the following one to two weeks. The merozoites escape the liver and re-enter the bloodstream where they assault red blood cells, continue to grow and divide, and eventually kill the blood cells.

Four different thermometers were used to measure the temperature of a sample of impure boiling water. The measurements are recorded in the table below.
Thermometer Temperature
Reading 1 Temperature
Reading 2 Temperature
Reading 3
W 100.1°C 99.9°C 96.9°C
X 100.4°C 102.3°C 101.4°C
Y 90.0°C 95.2°C 98.6°C
Z 90.8°C 90.6°C 90.7°C
The actual boiling point of pure water is 100.0°C.
What can be concluded from the data about the reliability and validity of the thermometers?
A.
Thermometer W is the most reliable.
B.
Thermometer X has the highest validity.
C.
Thermometer Z is the most reliable.
D.
Thermometer Y has the highest validity.
Reliability is another name for the precision of the measurement, and it means how well the value is repeated; this is, how close the different measurements are to each other. If the measurements are close one to each other, then the instrument is precise or reliable (high reliability).
Validity is another name for the accuracy of the measurement; this is, how close the measurement is to the true or accepted value.
With that, we can compare the reliability (precision) and validity (accuracy) of the four different thermometers.
Repeat the table:
Temperatures in °C:
Thermometer Reading 1 Reading 2 Reading 3
W 100.1 99.9 96.9
X 100.4 102.3 101.4
Y 90.0 95.2 98.6
Z 90.8 90.6 90.7
Reliability:
To analyze reliability (precision) we must compare the measures of every thermometer among them. A good approximation can be made calculating the range, i.e. the difference between the largest and the smallest readings:
For W: largest reading - smallest reading = 100.1°C - 96.9°C = 3.2°CFor X: largest reading - smallest reading = 102.3°C - 100.4°C = 1.9°CFor Y: largest reading - smallest reading = 98.6°C - 90.0°C = 8.6°CFor Z: largest reading - smallest reading = 90.8°C - 90.6°C = 0.2°CNow, you conclude that the most reliable is thermometer Z and the least reliable is thermometer Y. The complete ranking, from most reliable to least reliable is:
Z > X > W > Y
Validity:
To determine validity you must compare the mean of the three measures for each thermometer with the accepted value for the boiling point of pure water (100.0°C).
The mean is the sum of the three readings divided by 3.
The absolute error is calculated with the formula:
absolute error = | accepted value - calculated value |.
The calculated value is the mean.
For W: mean = (100.1 + 99.9 + 96.9)°C / 3 = 99.0°C
absolute error = 100.0°C - 99.0°C = 1.0°C
For X: mean = (100.4 + 102.3 + 101.4)°C / 3 = 101.4 °C
absolute error = 101.4°C - 100.0°C = 1.4° For Y: mean = (90.0 + 95.2 + 98.6)°C / 3 = 94.6°C
absolute error = 100.0°C - 94.6°C = 5.4°C
For Z: mean = (90.8 + 90.6 + 90.7)°C / 3 = 90.7°C
absolute error = 100.0°C - 90.7°C = 9.3°C
Now you can rank the thermometers as per their validity (accuracy):
1.0°C < 1.4°C < 5.4°C < 9.3°C
Thus, W is the most accurate, X is the second most accurate, Y is the third, and Z is the least accurate.

Why does diversity increase as height above land increases
Biodiversity rises with altitude initially before falling with height beyond that. Up until it reaches a diversity peak at about 1 300 to 1 800 m.
The biodiversity increases at higher geographical locations because There are more hiding locations. They are better for crop growth. They frequently include more than one kind of habitat.As latitude or altitude change, so does biodiversity. As we descend from high to low elevations, the diversity increases (i.e., from poles to equator). While the environment is harsh and plants have a brief growing season in the temperate region, tropical rain forests provide year-round growth-friendly circumstances. This enables the emergence and expansion of several species. On a mountain, there is an initial increase in species diversity after which there is a decline in species variety as you go up in elevation. At higher elevations, temperature drops and seasonal variations increase, which significantly diminishes.learn more about biodiversity here: https://brainly.com/question/26110061
