I think that the mobile home would have the lowest maintenance cost. But it all depends. You didn't give the information on where do the housing options take place so the cost may vary.

Answer:c mobile home

Explanation:

A mobile home is preconstructed structure, that can be run and transported to other location according to the choice of living place. This can be prepared from wood or other kind of cheap material which can keep the weight of mobile home low.

Thus mobile home is the lowest maintainace cost home for a single family.

serg [7]

Answer:

C. ribosomes

Explanation:

Both prokaryotic and eukaryotic cells contain certain structures called ORGANELLES. They possess some in common and others are not found in one or the other. According to this question, a small, free-floating organelle made from nucleic acid and amino acid is found in both eukaryotes and prokaryotes. This organelle is RIBOSOMES.

Ribosomes are organelles responsible for the synthesis of protein in both eukaryotes and prokaryotes. They can be found free-floating or attached to endoplasmic reticulum. Ribosomes are predominantly made of RNA (nucleic acid) and proteins i.e. Ribosomal RNA (rRNA) and proteins is their structural constituent. Hence, the organelle in this question is RIBOSOME.

Hunter-Best [27]

Answer:

The answer is 0.36 kg/s NO

Explanation:

the chemical reaction of NH3 to NO is as follows:

4NH3(g) + 5O2(g) ⟶4 NO(g) +6 H2O(l)

We have the following data:

O2 Volume rate = 645 L/s

P = 0.88 atm

T = 195°C + 273 = 468 K

NO molecular weight = 30.01 g/mol  

we calculate the moles found in 645 L of O2:

P*V = n*R*T

n = P*V/R*T

n= (0.88 atm * 645L/s)/((0.08205 L*atm/K*mol) * 468 K) = 14.78 moles of O2

With the reaction we can calculate the number of moles of NO and with its molecular weight we will have the rate of NO:

14.78 moles/s O2 * 4 molesNO/5 molesO2 * 30.01 g NO/1 molNO x 1 kgNO/1000 gNO = 0.36 kg/s NO

Luke and Sian want to plant a vegetable garden in their yard. A soil testing kit measures the soil pH at 5.0, but the lettuce th
dexar [7]

Answer:

So, Luke and Sian has to increase the pH of the soil by adding base to it.

Explanation:

The pH is defined as the negative logarithm of the hydrogen ion concentration in their aqueous solution.

pH=-\log[H^+]

  • With increase in hydrogen ion concentration the pH value decreases.
  • With decrease in hydrogen ion concentration the pH value increases.

The pH of the soil after testing it on a kit comes out be 5.0, but they both need pH of the soil to 6.5.

Comparison of pH of soil:

  =  5.0 < 6.5

= High hydrogen ion concentration > High hydrogen ion concentration

So, Luke and Sian has to increase the pH of the soil by adding base .Doing so will decrease the hydrogen ion concentration in the soil (where as addition of acid lower the pH of soil).
