Answer:
hydrosphere and biosphere
Explanation:
The spheres of the Earth are lithosphere, biosphere, atmosphere, hydrosphere etc. Hydrosphere refers to the collection of all the water bodies on the surface of the Earth e.g oceans, lakes, rivers etc. On the other hand, biosphere refers to the collection of life on Earth e.g plants, animals, microbes etc.
In this question, Water availability is said to impact plant growth and the animals who depend on plants for food. These water availability and the living organisms (plants and animals) it impacts are interactions between the HYDROSPHERE AND BIOSPHERE.
Answer:
After 48 hours amount left = 6.25 g
Explanation:
Given data:
Half life of potassium = 12 hours
Total mass = 100 g
Mass left after 48 hours = ?
Solution:
Number of half lives passed:
Number of half lives = Time elapsed / half life
Number of half lives = 48 hours/ 12 hours
Number of half lives = 4
At time zero = 100 g
At first half life = 100 g/ 2 = 50 g
At 2nd half life = 50 g/2 = 25 g
At 3rd half life = 25 g/2 = 12.5g
At 4th half life = 12.5 g/2 = 6.25 g

Answer:
Cell Division
Explanation:
Cells reproduce by the process of CELL DIVISION, which is the formation of an increased number of cells from a single parent cell. Mitosis is the type of cell division used for the multiplication of cells as it involves the synthesis of two identical number of daughter cells from a single parent cell.
However, certain drugs that may prevent the unregulated reproduction of cells is trying to directly affect the process of cellular division in that cell. This is because cell division is the way through which cells reproduce themselves.
<span>vaccine
The wording given is pretty much the exact definition of a vaccine. The key to how a vaccine works is that it provides to the immune system, samples of the surface proteins of the infectious materials. With those samples available, the immune system is able to produce antibodies that react to those proteins.</span>
