Answer:
Food record
Explanation:
A food record method is an assessment, study or act of collecting data related to food.
Although Food record method is time consuming and may not be accurate if subjects modify their eating habits during the time of the study the data collected here are of great importance. Some of the importance are;
(1). It helps in the registration of foods.
(2). The data can be used to describe a population's intake.
(3). The data can be used as a reference parameter in validation studies.
(4). The data can also be used with the Food Frequency Questionnaire.
It other disadvantage apart from its time consuming and error that might occur during the process of conducting the research is that it might be burdensome to the respondents.
How many atoms are in something determines it "mass"
Answer:
Option (B)
Explanation:
According to Hubble's law, the distance from the earth to the distant galaxies is directly proportional to their recessional velocity (redshift). This means that the more is the distance between the earth and a galaxy, the faster the galaxy is moving away from the earth.
Recessional velocity normally refers to the speed or velocity at which any astronomical body such as a planet, asteroid, star or galaxy moves away from a reference point, such as from earth.
Thus, the correct answer is option (B).
C. diffraction
Diffraction by description is occurrence
where the sound wave is interrupted or interacts with certain obstructions or
barriers. According to Huygens-Fresnel principle, it is where the waves are interfered
by said circumstances during its travel in the confined specific space.
Furthermore, the amount of
size the wavelength is directly proportional to its interacted slit or barrier
thus, these behaviors and amount are positively correlated.
Moreover, it occurs in a variety
of waves –may it be sound waves, water waves or electromagnetic waves.
