2.   A series circuit contains two devices, one with a resistance of 10 ohms and one with a resistance of 4 ohms. If the generator supplies a voltage of 42 V, what is the magnitude of the current? A. 3 A
  B. 1.75 A
  C. 2 A
  D. 1.33 A
3. When all parts of a circuit are composed of conducting materials, the circuit is said to be
    
  A. parallel.
  B. closed.
  C. open.
  D. shorted
4. Suppose you have two magnets. Magnet A doesn't have its poles labeled, but Magnet B does have a clearly labeled north and south pole. If these two are brought into contact with one another, which of the following could you expect?
    
  A. The side of Magnet A that's repelled by Magnet B's north pole must be Magnet A's south pole.
  B. The side of Magnet A that's attracted to Magnet B's south pole must be Magnet A's north pole.
  C. The side of Magnet A that's repelled by Magnet B's south pole must be Magnet A's north pole.
  D. The side of Magnet A that's attracted to Magnet B's north pole must be Magnet A's north pole

Answers

Answer 1
Answer: 2. In series, we add the resistance up
Use the formula V = IR to find the current.
R = 10+4 = 14, V=42
42=I (14)
I = 42/14 = 3 A

3. Closed

4. Answer B
This is because unlike poles attract and like poles repel.

Hope it helped!

which of the following best matches the fertilizer component with the molecule in which it will be incorporated by organisms in area?

Answers

The answer that best matches the fertilizer component with the molecule in which it will be incorporated by organisms in the area isNitrogen (N) - Amino acids (proteins).

Here's how the components of fertilizer are typically associated with the molecules they are incorporated into by plants:

1. Nitrogen (N): Nitrogen is often incorporated into amino acids, which are the building blocks of proteins. Proteins are essential for plant growth, development, and various biochemical processes.

2. Phosphorus (P): Phosphorus is typically incorporated into molecules like adenosine triphosphate (ATP) and nucleic acids (DNA and RNA). ATP is a molecule that stores and transfers energy within cells, while nucleic acids are critical for genetic information and cellular processes.

3. Potassium (K): Potassium is primarily involved in maintaining cellular water balance and ionic balance. It is not typically incorporated into specific molecules but rather plays a crucial role in overall plant function.

4. Magnesium (Mg): Magnesium is an essential component of the chlorophyll molecule, which is responsible for photosynthesis. Chlorophyll captures light energy and converts it into chemical energy.

5. Calcium (Ca): Calcium is not incorporated into a specific molecule like the others but serves as a structural component, providing rigidity to cell walls and contributing to overall plant structure and growth.

Therefore, the answer that best matches the fertilizer component with the molecule in which it will be incorporated by organisms in the area is:

Nitrogen (N) - Amino acids (proteins)

Fertilizer components such as nitrogen, phosphorus, and potassium can be incorporated by organisms through molecules like urea, ammonium ions, nitrates, phosphate ions, and phospholipids.

Biology: Fertilizer Components and Incorporation by Organisms

When it comes to fertilizers and the molecules they are incorporated into by organisms, it is important to consider the three main macronutrients: nitrogen, phosphorus, and potassium.

Nitrogen (N) is a key component of amino acids, proteins, and nucleic acids. It is commonly incorporated into molecules like urea, ammonium ions (NH4+), and nitrates (NO3-).Phosphorus (P) is an essential element for energy transfer and synthesis of nucleic acids and ATP. It is typically incorporated into molecules like phosphate ions (PO43-) and phospholipids.Potassium (K) is involved in osmoregulation and activation of enzymes. It is commonly incorporated into ions like potassium ions (K+).

The best matches for the fertilizer components are:

For nitrogen-based fertilizers, it could be urea, ammonium ions, or nitrates.For phosphorus-based fertilizers, it could be phosphate ions or phospholipids.For potassium-based fertilizers, it could be potassium ions.

The appropriate fertilizer components to be incorporated by organisms in an area would depend on the specific macronutrients needed by the organisms and the composition of the soil.
