The major factor that is based upon in ANOVA is the p-value. The null hypothesis is that the mean is the same for all groups. This could be rejected if according to statistical data analysis, the p-value is less than 0.5.
Answer:
Option A, Neither the researchers nor the study participants know who is receiving the drug and who is receiving the placebo.
Explanation:
In a double blind test, both the researcher and research participants are unaware of the exercise in a medical test . During the research active medication is given to some of the research participants making sure that researcher is unaware of that while observing all the participants. However, at the end of the experiment ,both the researcher and research participants get to know who has received the treatment.
Hence, option A is correct
Answer:Cattle ranching is the leading cause of deforestation in the Amazon rainforest
Explanation:Colombia, as a signatory to the New York Declaration on Forests, aimed by 2020 to halve natural forest loss and by 2030 to reach net-zero deforestation, meaning that any loss of forest will be offset by the replanting of native forest.
A. The increased biomass in the sunlit dish came from the carbon and oxygen atoms present in the carbon dioxide it took up during photosynthesis that it used to synthesize organic molecules.
Plants use photosynthesis in order to convert light energy (from the sun) into chemical energy, stored in carbohydrate molecules (such as sugars). This chemical energy can be further transformed to fuel some of the organism's activities. This chemical reaction (photosynthesis) is light-dependent and includes the use of carbon dioxide and water to produce sugars and oxygen. The seeds that were put on a sunny windowsill had plenty of light energy needed for their photosynthetic activity. This resulted in the accumulation of sugar molecules in the plant tissues and an increase in the biomass. These sugar molecules were synthesized by the carbon and oxygen atoms comprising the carbon dioxide molecules absorbed during photosynthesis.
B. The most likely explanation for the why the dark-grown seedling lost biomass is that cellular respiration in the cells of the seedlings consumed the starch and oils present in the seed as sources of energy.
Plants use cellular respiration in order to constantly supply energy to their cells. This chemical reaction uses the sugar molecules produced by the photosynthesis and stored in the plant tissues to get energy. Seeds put in a dark cupboard did not have access to any light energy, therefore, they could not perform photosynthesis. As a result, they had to perform respiration and consume starch and oils which were present in the seed to get the necessary energy. This resulted in a reduction in their biomass.
Answer:
The higher temperature of the hot soup means that the water molecules in the soup will move faster on average than the water molecules in iced lemonade. 3. Temperature is a measure of the average kinetic energy of particles of a substance. The higher the kinetic energy of particles is, the higher the temperature is.
