Q1. <span>What is the mass of 1 cup of water and 2 teaspoons of salt?
The answer is 258 g.

Density (D) is mass (m) divided by volume (V): D = m/V
So, m = D * V

According to the US units, the volume of 1 cup is: V = 236.6 cm</span>³.
The density of the water is: D = 1 g/cm³.
So, the mass of 1 cup of water is: m = 1 g/cm³ * 236.6 cm³ = 236.6 g.

According to the US units, the volume of 1 teaspoon is: V = 4.93 cm³.
The density of salt is: D = 2.17 g/cm³.
So, the mass of 1 teaspoon of salt is: m = 2.17 g/cm³ * 4.93 cm³ = 10.7 g.

The mass of 1 cup of water and 2 teaspoons of salt is
236.6 g + 2 * 10.7 g = 236.6 g + 21.4 g = 258 g.


Q2. <span>What is the density of 1 cup of water and 2 teaspoons of salt?
</span>The answer is 3.17 g/cm³.

Density (D) is mass (m) divided by volume (V): D = m/V

According to the US units, the volume of 1 cup is: V = 236.6 cm³.
The mass of 1 cup of water from question 1 is: m = 236.6 g.
So, the density of 1 cup of water is: D = 236.6 g / 236.6 cm³ = 1 g/cm³

According to the US units, the volume of 1 teaspoon is 4.93 cm³. The volume of 2 teaspoons is: V = 2 * 4.93 cm³ = 9.86 cm³.
The mass of 1 teaspoon of salt from question 1 is: m = 10.7 g. The mass of 2 teaspoons of salt is: m = 2 * 10.7 g = 21.4 g.
So, the density of 2 teaspoons of salt is: D = 21.4 g / 9.86 cm³ = 2.17 g/cm³

The density of 1 cup of water and 2 teaspoons of salt is:
1 g/cm³ + 2.17 g/cm³ = 3.17 g/cm³


Q3. <span>What is the mass of 1 cup of water and 3 teaspoons of salt?
The answer is 268.7 g.

</span>Density (D) is mass (m) divided by volume (V): D = m/V
So, m = D * V

According to the US units, the volume of 1 cup is: V = 236.6 cm³.
The density of the water is: D = 1 g/cm³.
So, the mass of 1 cup of water is: m = 1 g/cm³ * 236.6 cm³ = 236.6 g.

According to the US units, the volume of 1 teaspoon is: V = 4.93 cm³.
The density of salt is: D = 2.17 g/cm³.
So, the mass of 1 teaspoon of salt is: m = 2.17 g/cm³ * 4.93 cm³ = 10.7 g.

The mass of 1 cup of water and 3 teaspoons of salt is
236.6 g + 3 * 10.7 g = 236.6 g + 32.1 g = 268.7 g.


Q4. <span>What is the density of 1 cup of water and 3 teaspoons of salt?
The answer is 3.17 g/cm</span>³<span>

</span>Density (D) is mass (m) divided by volume (V): D = m/V

According to the US units, the volume of 1 cup is: V = 236.6 cm³. 
The mass of 1 cup of water from question 1 is: m = 236.6 g.
So, the density of 1 cup of water is: D = 236.6 g / 236.6 cm³ = 1 g/cm³

According to the US units, the volume of 1 teaspoon is 4.93 cm³. The volume of 3 teaspoons is: V = 3 * 4.93 cm³ = 14.79 cm³.
The mass of 1 teaspoon of salt from question 1 is: m = 10.7 g. The mass of 3 teaspoons of salt is: m = 3 * 10.7 g = 32.1 g.
So, the density of 3 teaspoons of salt is: D = 32.1 g / 14.79 cm³ = 2.17 g/cm³

The density of 1 cup of water and 3 teaspoons of salt is:
1 g/cm³ + 2.17 g/cm³ = 3.17 g/cm³



Q5. What is the mass of 1 cup of water and 4 teaspoons of salt?
The answer is 279.4 g.

Density (D) is mass (m) divided by volume (V): D = m/V
So, m = D * V

According to the US units, the volume of 1 cup is: V = 236.6 cm³.
The density of the water is: D = 1 g/cm³.
So, the mass of 1 cup of water is: m = 1 g/cm³ * 236.6 cm³ = 236.6 g.

According to the US units, the volume of 1 teaspoon is: V = 4.93 cm³.
The density of salt is: D = 2.17 g/cm³.
So, the mass of 1 teaspoon of salt is: m = 2.17 g/cm³ * 4.93 cm³ = 10.7 g.

The mass of 1 cup of water and 4 teaspoons of salt is
236.6 g + 4 * 10.7 g = 236.6 g + 42.8 g = 279.4 g.


Q6. What is the density of 1 cup of water and 4 teaspoons of salt?
The answer is 3.17 g/cm³

Density (D) is mass (m) divided by volume (V): D = m/V

According to the US units, the volume of 1 cup is: V = 236.6 cm³. 
The mass of 1 cup of water from question 1 is: m = 236.6 g.
So, the density of 1 cup of water is: D = 236.6 g / 236.6 cm³ = 1 g/cm³

According to the US units, the volume of 1 teaspoon is 4.93 cm³. The volume of 4 teaspoons is: V = 4 * 4.93 cm³ = 19.72 cm³.
The mass of 1 teaspoon of salt from question 1 is: m = 10.7 g. The mass of 4 teaspoons of salt is: m = 4 * 10.7 g = 42.8 g.
So, the density of 3 teaspoons of salt is: D = 42.8 g / 19.72 cm³ = 2.17 g/cm³

The density of 1 cup of water and 4 teaspoons of salt is:
1 g/cm³ + 2.17 g/cm³ = 3.17 g/cm³

What are some ways that the biosphere interacts with other three components of the Earth system?
Ivenika [448]

Answer:

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.

You are performing a biochemical purification of enzymes involved in DNA replication. You have purified the replisome. You wish
algol [13]

Confirm that the sample has both helicase and primase activities, but not the ability to synthesize DNA

  • The replisome is a multiprotein-RNA complex that is required for the replication of DNA. The replisome consists of different proteins which include:

            1. Helicase enzymes that unwind and separate the DNA strand

            2. Replication factor C (RFC), a DNA-dependent ATP that acts as an activator of DNA polymerase.

           3. Proliferating cell nuclear antigen (PCNA)

           4. DNA gyrase/topoisomerase that cuts and reseals DNA strands, which is essential for DNA synthesis.

           5. Primase enzyme that synthesizes short RNA fragments called primers.

          6. DNA polymerase III, an enzyme that catalyzes the polymerization of deoxyribonucleotides into a DNA strand.

           7. DNA ligases enzymes that form phosphodiester bonds at a single-strand break in DNA

  • A primosome is a multiprotein complex responsible for creating RNA primers on single-stranded DNA (ssDNA) during the replication process.
  • The primosome is composed of different primase and helicase enzymes. In<em> Escherichia coli</em>, it consists of PriA helicase, PriB, PriC, DnaB helicase, DnaG (encoded by the dnaG gene), DnaC and DnaT primase.
