Answer:
According to the model, the "villi" of small intestines is being damaged as an impact of celiac disease. Small intestines are responsible for absorption of nutrients and minerals from food, this occurs through villi, in case of damaged villi absorption is interfered, thus disturbing the digestive system. If the nutrients, minerals or vitamins are not being absorbed well by small intestines then they will be excreted out of the body and will not be transported to the blood and other areas, this would result in deficiency of minerals and vitamins in blood that cause weakness.
Water Cycle:
1. It is stored in the ground.
2. Evaporation, transportation, precipitation
3. Runoff comes straight from precipitation. Infiltration is from the ground while run off never went in the ground.
4. It will usually end up in the same place, the ocean
5. Water levels rise, temperatures rise, CO2 in atmosphere increases
Carbon Cycle:
1. Carbon is important because it is one of the basic building blocks of life.
2. Trees, animals, grass, decomposition, combustion, fossil fuels
3. Carbon enters as photosynthesis.
4. Carbon enters water to the soil decomposition. Aquatic plants have plenty of water to work with, so their main challenge is getting enough sunlight and air.
6. By breathing in the oxygen from plants.
7. Two ways carbon return from animals into water is through cellular respiration and decomposition.
8. Combustion is when we dig up the fossil fuel and burn it, then what is left goes into the air starting the cycle again.
9. Deforestation reduces the capacity of forests to be carbon sinks.
Nitrogen Cycle:
1. Nitrogen is important because it helps us grow crops, and it produces grass for animal.
2. It comes from lightning and is named nitrogen fixation.
3. Ammonification and then transitions into nitrification and then to assimilation.
Phosphorus Cycle:
1. It forms part of life sustaining molecules like DNA and RNA.
2. Phosphorus is never found in the atmosphere.
Answer:
<u>independent variable:</u> size of soccer ball
<u>dependent variable</u>: period of time the balls stay in the air
<u>control variable</u>: parts of the body used to juggle the ball
Explanation:
The independent variable is the manipulatable variable supplied into an experiment. It is a variable that directly affects the dependent variable.
The independent variable is the outcome variable. It is the variable that is primarily measured from experiments whose value depends on the value of the independent variable.
The control variables are those that are kept constant throughout the course of experiments. In other words, they do not directly affect experimental outcomes.
Hence, in the illustration;
<u>independent variable</u>: size of soccer ball
<u>dependent variable</u>: period of time the balls stay in the air
<u>control variable</u>: parts of the body used to juggle the ball
Answer:
B. physical anonymity.
Explanation:
Anonymity can be explained in psychological research as a situation whereby the data collected from participants is confidential and cannot be traced to any particular individual.
Deindividuation is known to be a phenomenon in which people engage in seemingly impulsive and sometimes violent acts in situations in which they believe they cannot be personally identified.
In this case, people that are not physically present tend to be more hostile or engaged in some cruel act. This is because they know they can be seen face-to-face, and people will not know that they are the perpetrator of the act.
The right answer is A.Transcription uses uracil.
The genes carried by the DNA will be encoded in another form: messenger RNA, during a process called "transcription".
The DNA and RNA molecules are chemically very close, but the second has an extra oxygen (in red on the right of the letters) on the sugars (riboses) that make up its nucleotides (the DNA actually contains deoxyribose). In addition, the thymine (T) of DNA is replaced by uracil (U) in RNA.
