Answer:
B cells and T cells are the white blood cells of the immune system that are responsible for adaptive immune response in an organism. Both the cells are made in the bone marrow.Explanation:
B cells produce antibodies, and T cells destroy infected cells. So, the correct option is D.
What are B cells and T cells?The two primary categories of lymphocytes are T cells and B cells. Antibody molecules made by B cells can attach to and kill invasive viruses and bacteria. T cells are the immune system's first line of defence against foreign invaders. They also create cytokines, that are biological agents that aid in the activation of other immune system components.
T cells can eliminate malignant or contaminated cells. Moreover, they control overall immune response by assisting B cells in eradicating foreign infections. Antibodies are made by B cells. An antibody is a class of protein produced by B lymphocytes, sometimes known as B cells.
Therefore, the correct option is D.

Why is water pollution a concern if water is continuously cycled through Earth's systems?
Answer:The Earth's Water Cycle involves Evaporation, Condensation, and Precipitation. Evaporation purifies the water resulting to the replenishment of freshwater to the Earth.
Water pollution is a concern despite of the water being continuously cycled through Earth's systems because the source of pollution is has not been removed.
Water pollution is defined as the contamination of bodies of water. Pollutants are directly or indirectly released to the bodies of water causing the water to be polluted.
Imagine: A river is filled with garbage, it is polluted. The water from the river undergoes the water cycle but since the garbage is still present in the river, the freshwater that comes from precipitation becomes polluted.

Why are streak plates used the test minerals?
A. They show you the silicon content of the minerals
B. They show you the colors of the impurities in the mineral
C. They show you the true color of the minerals
Answer: c
Explanation: correct answer
Streak plates are used to test minerals because they show you the color of the mineral in powdered form. So, the correct option is C.
What are Streak plates?Small pieces of unglazed glass or porcelain are known as streak plates, and they are used in mineralogy to assess the streak color of a mineral. They are usually a few inches in length and about an inch in width.
The streak of a mineral is its color after it has been ground into a fine powder and rubbed across a streak plate. Because some minerals have recognizable colors that differ from their actual color, it can be helpful to identify them.For example, hematite is a dark brown mineral with bright red streaks. You can differentiate hematite from other dark brown minerals by looking at the color of the streaks.
Therefore, the correct option is C.
