What are some sources of error found in osmosis experiment​

Biology

Margarita [4]3 years ago

Answer:


Well, you may have errors in measuring the concentration of your solution, or in weighing the potato slices before and after the experiment. If you use different potatoes, or different parts of the potato are different (eg one part for some reason dryer) then that could add to the error. If you put a potato into an isotonic solution it should remain the same weight, but if you have more solute in the water than in the potato, water from the potato will be drawn out (like salting a snail or tomato), but if the water has less solute than the potato, it will be drawn into the potato, making it heavier.

Answer:

In the experiment it includes several separate tests and errors that can be easily occurring. One of the errors is the potato cores were not necessarily all the same weight to even begin with. However, another source of error is the cores were not exactly completley covered by the solution, which is due to the larger beaker.

Scientists collect data then develop and use models to make predictions about future climate conditions.
goldfiish [28.3K]

Scientists collect ongoing data from many locations around the world. They then input this data into a mathematical or computer-based model to simulate real-world conditions.

<h3>What is climate forecasting?</h3>

Weather averages and other climatic characteristics are predicted by climate forecasts from a few weeks to a few years in advance. Such forecasts are increasingly being made using thorough models of the Earth's climate system.

Since it aids in forecasting future climate conditions, climatology and weather forecasting are crucial. The likelihood that snow and hail will reach the surface can be calculated using latitude. You may also determine the thermal energy from the sun that a location can get.

The preferential use of phosphatidylinositol and phosphatidylethanolamine in the cytoplasmic leaflet of membranes leads to incre
spayn [35]

Answer:

The best answer to the question: The preferential use of phosphatidylinositol and phosphatidylethanolamine in the cytoplasmic leaflet of membranes leads to increased:___ would be, D: All of the answers are correct.

Explanation:

There is still a lot of debate among scientists as to the exact way in which phospholipids are distributed between the two leaflets of a cell´s plasma membrane, but what they do know is that there are four kinds, and that phosphatidylinositol (a sterol) and phosphatidylethanolamine appear most commonly on the cytosolic, or cytoplasmic side of the membrane. They also believe that it is this particular arrangement which allows the cytoplasmic side of the membrane to be slightly negatively charged and this role will play a major part in a membrane´s ability to generate an action potential. Also, it is known that these negatively charged ends of the bilayer will allow certain proteins, positively charged ones, to be inserted, and connected to it, to become transporters, or mediators in action potentials and normal activities of cells. Finally, since fatty acids and cholesterol are associated with phospholipids, but have a tendency to be attracted to these particular two types, they tend to give the overall structure fluidity, but also permit  the inner leaflet to assume its particular circular shape around the cytoplasm. This is why the answer is D.

How can someone inherit a trait from their parent while the sibling does not please help me!!!
Katyanochek1 [597]

Answer:

Genetics is the study of how heritable traits are transmitted from parents to offspring. Humans have long observed that traits tend to be similar in families. It wasn't until the mid-nineteenth century that larger implications of genetic inheritance began to be studied scientifically.
