What is the dependent variable in tornado in a bottle?
Vlad1618 [11]

Answer;

The amount of water and the temperature of the water and the angle the bottle was set in.

Explanation;

The two main variables in an experiment are the independent and dependent variable;

-An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.

For example; the dependent variable in tornado in a bottle is the amount of water and the temperature of the water and the angle the bottle was set in.

Phosphorus (P) is the element with the atomic number 15. Which of the
viva [34]

Explanation:

   Isotopes:

                          ₁₅³¹P   and     ₁₅³²P

     Given parameters:

       ₁₅³¹P                                                   ₁₅³²P          

   Mass number = 31                                    32

   Atomic number = 15                                 15

The two atoms are isotopes. Now let us derive numbers of their subatomic particles

                       ₁₅³¹P                                             ₁₅³²P  

Protons              15                                                 15

Electrons           15                                                  15

Neutrons         (31-15) = 16                               (32-15) = 17

Because they are isotopes, they differ in the number of neutrons alone.

Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences  in the number of their neutrons.

We clearly see that the mass number and number of neutrons pertaining to the atom differs. This makes them isotopes.

A protein domain is another phrase describing what type of structure of a protein?.
dlinn [17]

Answer: A protein domain is a region of the protein's polypeptide chain that is self-stabilizing and that folds

independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains.

One domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions.

In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length.

The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium binding EF-hand domain of calmodulin.

Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins.
