This problem is describing the state two gases have when separated and together as shown on the attached picture. First of all, diagram 1 shows how they are separated in two containers with apparently equal volumes, whereas diagram 2 shows the removal of the barrier so that they get mixed together.
In this case, we can analyze that each gas has its own pressure and due to the removal of the barrier, both pressure and volume undergo a change. Thus, we can infer that the final volume is doubled with respected to the initial one for each gas, causing the pressure of each gas to be halved and the total pressure the half of the added ones, in agreement to the Boyle's law (inversely proportional relationship between pressure and temperature).
Therefore, the correct choice is:
C. The partial pressure of each gas in the mixture is half its initial pressure; the final total pressure is half the sum of the initial pressures of the two gases.

Apartheid was a legal racial separation system that ruled the Republic of South Africa from 1948 to 1993. Apartheid's mechanisms were in place before its creation, and South Africa is still dealing with these issues. Apartheid divided various races into different regions, and discrimination against people of color was not only acceptable, but also legal, with white people having full priority on housing, jobs, education, and political power. Even though South Africa was constantly chastised for the system, it wasn't until 1991 that the legal system of apartheid began to crumble, and it was finally brought down in 1993.
What is Apartheid?
Apartheid has been legally abolished, but whites and blacks continue to coexist in separate communities. There are still "black" and "white" neighborhoods, as well as "black" and "white" churches and restaurants. When the international media writes about Southern Africa, they almost always mention the country's "fading rainbow" and experiment in multi-ethnic democracy .

Paramecia are examples of unicellular organisms. They are protists.
<h3>Protists</h3>
Protists are eukaryotic unicellular (single-celled) organisms that do not fit into any other category.
Paramecia are protists microorganisms generally found in aquatic habitats (e.g., a pond).
Paramecia generally have an oblong shape and they are covered with tiny structures known as cilia (for motion).
