Answer :
Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.
Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.
When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.
Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.
Well, scientists are working hard to find out more about cells, so they should know all of the cells. The Lokiarchaeota cell is one of the only ones they have yet to find out stuff about. Scientists also need to know about it, because it is a part of our bodies, and maybe sometimes they can cause infection in the body. Scientists need to know if it could lead to some of the biggest infections ever.
Answer:
In a solid atoms are packaged tightly together and move slowly
Answer:
Water is a control
Explanation:
From the question, the independent variable is energy drink and the dependent variable is running 50 yard of ash.
An independent variable is a variable that can stand alone in an experiment.
Dependent variable is a variable that is beeping altered, tested and measured and it's dependent on the independent variable.
The running of 50 yard Yash depend on the energy drink which is independent.
Water is a control because it is not tested for dependent variable and it's minimize the effect of dependent variable. This is because the energy drink give energy to run 50 yard Yash and that is the dependent variable.
<span>This fact pattern best fits the idea of the Gradualism Model. This particular model focuses on how species slowly grow and change through evolution over time. Essentially, the model is that species will very slowly change into another type of species as time passes.</span>
