They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid. Prokaryotic organisms have varying cell shapes.
Explanation:
Answer:
Explanation:
The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane. Many prokaryotes also carry small, circular DNA molecules called plasmids, which are distinct from the chromosomal DNA and can provide genetic advantages in specific environments.
A molecule _____. is made of more than one atom is the same as a compound must be made of more than one element can only contain two atoms
Answers
Answer:
it is not an act answer but it has information
Explanation:
A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).
A molecule is made up of two or more atoms, and it can be composed of atoms of the same element or different elements.
A molecule is a particle that consists of two or more atoms chemically bonded together. It is the smallest unit of a compound that retains the chemical properties of that compound.
Molecules can be composed of atoms of the same element or different elements. When atoms of the same element combine to form a molecule, it is called a diatomic molecule.
On the other hand, molecules can also be formed when atoms of different elements combine. In this case, the molecule is considered a compound. Compounds are composed of two or more different elements chemically bonded together.
Hence, a molecule is made up of two or more atoms, and it can be composed of atoms of the same element or different elements.

Explanation:
One mole of ANY element contains the:
same mass as one mole of any other element
same number of atoms as one mole of any other element
same gram-formula-weight as one mole of any other element
both the first and second choices
Answers
Answer:
1)The molar mass of an atom is simply the mass of one mole of identical atoms. However, most of the chemical elements are found on earth not as one isotope but as a mixture of isotopes, so the atoms of one element do not all have the same mass.
2)Equally important is the fact that one mole of a substance has a mass in grams numerically equal to the formula weight of that substance. Thus, one mole of an element has a mass in grams equal to the atomic weight of that element and contains 6.02 X 1023 atoms of the element.

A patient is given 0.050 mg of technetium-99 m (where m means metastable—an unstable but long-lived state), a radioactive isotope with a half-life of about 6.0 hours.
How long until the radioactive isotope decays to 1.3×10−2 mg ?
Answers
The correct answer is 9.6h.
As you know, a radioactive isotope's nuclear half-life tells you exactly how much time must pass in order for an initial sample of this isotope to be halved.
Using the formula , A = Ao. [tex]1/2^n[/tex]
where , A- final mass after decay
Ao - initial mass
n - the number of half-lives that pass in the given period of time
Now, putting all the values, we get
1.3 × [tex]10^-2[/tex] mg = 0.050 mg × [tex]1/ 2^n[/tex]
Take the natural log of both sides of the equation to get,
㏑[tex](1.3 . 10^{-2} / 0.050 )[/tex] = ㏑[tex]((1/2)^{n})[/tex]
㏑[tex](1.3 . 10^{-2} / 0.050 )[/tex] = n. ln[tex](1/2)\\[/tex]
n = 1.6
Since n represents the number of half-lives that pass in a given period of time, you can say that
[tex]n = t / t _{1/2}[/tex]
t= 1.6 × 6 h
t = 9.6h
Hence, it will take 9.6 h until the radioactive isotope decays.

How much energy, in kWh, is used if a hair dryer with a power of 20 watts was used for
0.5 hours? (Remember to convert to kW first!!!!)
Answers
Answer:
0.01kWh
Explanation:
Given parameters:
Power = 20watts
Time = 0.5hrs
Unknown:
Energy of other dryer = ?
Solution:
The electrical energy of the dryer can be calculated using the expression below;
Electrical energy = IVt
P = IV
I is the current
V is the voltage
t is the time
P is the power
Convert 20watts to kilowatts;
1000watts = 1kW
20watts = [tex]\frac{20}{1000}[/tex] = 0.02kW
Electrical energy = 0.02kW x 0.5hr = 0.01kWh

Hope this helps! Have a nice day!Two students are planning an investigation to determine if ionic or covalent bonds have stronger intermolecular. They are using salt (ionic), sugar (polar covalent), and moth balls (nonpolar covalent). Which one of the tests would not be relevant to their experiment?
Answers
Answer:
conductivity in water/ solid state
Explanation:
becuase, they both dissolve in water the same, therofre it is the least helpful.
The test that will be least helpful to determine if ionic or covalent bonds have stronger intermolecular is solubility in water. Therefore, option (B) is correct.
What is the covalent and ionic bond?The covalent bonds are formed by the shared pair of electrons between the atoms while the ionic bonds are formed by the complete transfer of electrons between the atoms. Methane is covalent while NaCl is an ionic compound.
Ionic compounds have strong intermolecular forces of attraction while covalent compounds don't. The covalent solids exhibit less melting point compared to the ionic compound.
Covalent compounds are generally more flammable than ionic solids. Salt conducts electricity in the water while sugar does not conduct electricity in the water.
As both students are trying to find the stronger intermolecular forces between ionic or covalent bonds, both salt and sugar are soluble in water. Therefore, the solubility in water would not be relevant to their experiment
