The answer is B 2. As it says Atom Number of Protons and Number of Neutrons, from my understanding it means that the first number after the letter is the number of protons and the second number is the number of neutrons.

Now, If there are 6 protons in a nucleus that means there are 6 electrons on the outside, so A and D are the same element. However, you may be confused because of the different number of neutrons (6 and 7 or 7 and 8) this only means that one is and isotope of the element.

*Isotopes are atoms with the same number of protons but different number of neutrons. (Basically, same element different mass)

A cell created by cloning is genetically A identical to its parent. B identical to its stem cell. C unique because it is a mixtu
stiks02 [169]

Answer: Identical to its parent.

Explanation:

The cloning can be defined as the process by which genetically identical individuals of an organism is produced either artificially or naturally.

The cloning in case of biotechnology refers to the creating the clones of organisms or copies of cells or DNA of the parent cell that is being used in the process.

The parent cell is cloned and numerous copies is made just like that of the asexual reproduction in the nature.

Example: Dolly the sheep.

1.00 mole of an ideal monoatomic gas at STP first undergoes isothermal expansion so that the volume at b is 2.5 times the volume
MrRa [10]

Answer:

the pressure at c = 0.27 atm

Explanation:

Given that:

number of moles (n) = 1.0 moles

Value of gamma in the monoatomic gas (γ) = 5/3

During an isothermal expansion, the volume at b is = 2.5 times the volume at a ; this implies that:

V_b = 2.5 V_a

∴ To calculate  the pressure at c from a; the process is adiabatic compression; so we apply:

P_aV_a^\gamma=P_cV_c^\gamma

\frac{P_c}{P_a}=[\frac{V_a}{V_c}]^{(2/3)

\frac{P_c}{1.0 atm}=[\frac{1}{2.5}]^{(2/3)

P_c=0.27 atm

Thus, the pressure at c = 0.27 atm

Sati [7]
Obliviously not all rocks have holes in them
It is called vesicular texture These refers to viscles holes pores or cavities within the igneous rock.the vesicles are the result of gas expansion(bubbles).which often occur during volcanic eruptions .
