Answer:
2 levels of the independent variable and 0 levels of dependent variable
Explanation:
Levels of independent variable indicate the types of experiment here. Here we have the control experiment and experimental group. The control experiment/group is the group that is not altered and used to measure the experimental group. The control group is the 50 children that took nutritious breakfast while the experimental group is the 50 children that took doughnuts /non nutritious food. If there are more than two types of experiment, the number of experiment types are the number of levels of the independent variable. The dependent variable here has 0 levels
Answer:
4
Explanation:
I'm not sure if this answers right so don't come attacking at me
Formula:
Hydrogen Chloride = HCl (Chemical Compound)
Sodium = Na (Chemical Element)
Reactants:
A simple definition of a reactant can be the substances that go into a chemical reaction. By substances I mean any chemical.
Products:
A simple definition of a product can be the substances produced at the end of the reaction. Again by substances I mean any chemical.
Definition of the answer:
We know that Sodium is a Chemical Element and as decribed in the picture it was mixed by Hydrogen Chloride and we know that is a Chemical Compound. So in this case the Na CI can be the product that was produced at the last and it was the result after the chemical reaction was taken place. The reactant can be the Sodium. I chose that because Reactant is a substance/chemical that goes into a chemical reaction. So as seen in the picture it went into the beaker.
Hope this helps.
Answer:
First-hand ethnographic fieldwork
Explanation:
Ethnography is the detailed account of a society and its culture by observing the social interactions that people have. This gives us an accurate description of a society and its culture as it not influenced by outside factors.
Here, Maria is studying the the lives of women in coffee farming communities in Brazil. She is observing them directly and making sure her presence does not influence their interactions. She is also doing this herself which means her research will not be affected by someone else's perspective.
Hence, she is using the strategy of first-hand ethnographic fieldwork.
Answer: Cannon-Bard theory: emotions occur before a body response
Explanation: Cannon-Bard theory explains that emotions and body response occur together. This theory is also known as the Thalamic theory of emotion. It was proposed by Walter Cannon and Philip Bard. An example of this theory is seeing a wild and dangerous animal can trigger fear and a racing heartbeat.
