Answer: The correct answer is option C.
Explanation:
A false negative test is a diagnostic error in which a test shows absence of a disease even when a person is having a disease.
Similarly, in the given question a sample has anthrax spores; however, antibody test fails to show the presence of anthrax. Thus, it is a false negative.
In contrast, false positive error is the error in which the test shows the presence of disease even when a person is not suffering from it.
Sampling error is a statistical error.
Thus, the correct answer is option C.

Answer;
Lake temperatures will increase, but dissolved oxygen in the water will decrease.
Explanation;
If water vapor continued to increase in our atmosphere, Lake temperatures will increase, but dissolved oxygen in the water will decrease.
As the temperature of the atmosphere rises, more water is evaporated from the surface of the lakes. This causes an increase in the relative humidity leading to more water vapor in the atmosphere. The result is decreased the amount of dissolved oxygen in the water
Answer:
Yes.
Explanation:
Yes, early Earth's atmosphere was formed from the poisonous mixture of helium and hydrogen gases. But with the passage of time when Earth's crust began to cool, the composition of the atmosphere changed and carbondioxide and water concentration in the atmosphere increases due to carbondioxide gas emission from the volcanoes and evaporation of water from water bodies present on the surface of earth.
