Answer:
The scientific method is a process that can be used to answer any questions . The process begins when a scientist makes an observation. Then, they do research to learn more about the topic and write a hypothesis. The scientist will make predictions and conduct an experiment, eventually coming to a conclusion. They will share their results with other scientists to help further discovery.
Explanation:
The Scientific method is process used to observe, predict and explain phenomena around us. It involves a series of steps listed as follows:
1. Making observations: the scientist must be a keen observer of events around him
2. Ask questions: the scientist asks questions based on the observations
3. Form a hypothesis and make predictions: the scientist puts forward a reasonable explanation for the observations known as hypothesis. Predictions are then made and tested upon.
4. Experimentation: experiments are conducted to test the hypothesis and the predictions made.
5. Analysis of data and conclusion: the result of the experiments are analysed and conclusion are then drawn.
6. Communication of results: the results obtained from the experiments are then shared with other scientists to aid further research and discoveries.
B. Because inertia is the speed of the object and if the object weighs less, it falls faster :)
Pretty sure after 1 week you've found the answer at some point...
but Global winds help to distribute heat and water vapor around the Earth, which influences temperature and precipitation patterns around the entire globe.<span> Global winds are caused by pressure differences in the atmosphere from warm air rising to the poles. The flowing air carries water vapor and creates specific weather patterns, such as increased rainfall in the tropics.</span>
Here's my best guess
the volume of the unit cell is (385*10^-12)^3=5.7066*10^-29 m^3
multiply by density to get mass
mass = (7 g/cm^3)*(100^3 cm^3 / 1^3 m^3) * 5.7066*10^-29 m^3= 3.99466*10^-22 g
covert to moles
3.99466*10^-22 g * 1 mol / 239.82 g = 1.6657 *10^-24 mol
convert to number of units
1.6657 *10^-24 mol * 6.23*10^23 units/mol = 1.04
385 pm = 3.85*10^(-8) cm
The volume of the unit cell is the cube of that, which is 5.71*10^(-23) cm^3. Since the ratio of mass to volume (i.e. the density) must be the same no matter what amount of TlCl you have, you can say:
7 = x/(5.71*10^(-23)), where x is the mass of the unit cell. Solving for x, you get 4*10^(-22) g.
The mass of a molecule of TlCl is 240 amu, which in grams is 4*10^(-22) g. The mass of the unit cell and the mass of a molecule of TlCl is the same. Therefore there is one formula unit of TlCl per unit cell.
Answer:
125 carbon atoms are from proline are present in the protein.
Explanation:
Molecular formula of proline = ![C_5H_9NO_2](https://tex.z-dn.net/?f=C_5H_9NO_2)
Number of carbon atoms = 5
If a human protein has 25 proline monomers.
Number of proline molecules = 25
Number of carbon atoms in 25 molecules of proline :
![5\times 25 = 125](https://tex.z-dn.net/?f=5%5Ctimes%2025%20%3D%20125%20)
125 carbon atoms are from proline are present in the protein.
