A) gravitropism is how they "know"
When the temperature of the air becomes almost equal to the dew point the air becomes saturated and the relative humidity during this condition becomes 100%. If the temperature of the air decrease below the dew point the relative humidity will be 100% or exceeds 100%. This condition, when the temperature of the air decreases below the dew point is called supersaturation but most of the time the temperature of the air will be lower than the dew point.
Answer:
The correct answer is option - phagocytosis.
Explanation:
The explained experiment is the pulse-chase experiment in this the cells that are involved are macrophages. Macrophages are the immunity cells that have a large number of the lysosomes for killing the pathogens enters in the cell brought into the cell through the process of phagocytosis.
Phagocytosis takes place with the help of the enzyme called hydrolytic enzyme that is synthesized in the endoplasmic reticulum and modified by Golgi and moves to the lysosome.
Thus, the correct answer is option - phagocytosis.
Answer:
C) Re-do the measurements, several times, and take the average density before making a decision.
Explanation:
For the correct identification of the metal, weather its nickel or copper, Carl should repeat the experiment several times and take the average density before making the decision. It is important because it reduces the chance of error and ensure the data integrity. The more the sample size is, lessen would be the error.
