Which of the following are false about Prokaryotic Transcription termination?
A. It can occur in a factor dependent fashion.
B. It can occur in a factor independent fashion.
C. It may involve Rho protein.
D. none of the above.
Answer: none of the above
Explanation:
In Prokaryotic Transcription termination, it should be noted that the RNA polymerase transcribes through a terminator sequence, which in turn results in the polymerase to be separated from the DNA and thereby leads to its release of the transcrip.
Prokaryotic Transcription termination can occur in a factor dependent fashion, can occur in a factor independent fashion and may involve Rho protein.
Therefore, none of the options is false.
The elements carbon, hydrogen, oxygen, and nitrogen make up which percentage of the human body?
Answer:
96% Hope it helps
Explanation:
Roughly 96% of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water. The remaining 4% is a sparse sampling of the periodic table of elements.
For a trip to the Moon, a rocket must lift off from
Earth's surface. Suppose it takes 5 minutes for the
rocket to reach a velocity of 6,000 m/s upward from
a starting velocity of 0 m/s. What is the rocket's
acceleration?
Answer:
20 m/s^2
Explanation:
given,
final velocity (v) = 6000m/s
initial velocity (u) = 0m/s
time taken (t) = 5 minutes
= 5×60second
= 300second
acceleration(a) = ?
we know that,
a = (v-u)/t
= (6000-0)/300
= 20 m/s^2

An aluminum cylinder has a radius of 3.2 cm and a length of 8.6 cm. What is the mass of the aluminum cylinder if aluminum has a density of 2.7 g/cm3?
please help :)
Answer:
750g of Aluminum
Assuming 8.6 cm lenth is the height of the cylinder. The volume of a cylinder is: V = [tex]\pi[/tex]*r^2*h
V = 3.14cm x 10.24cm x 3.6cm
V = 280cm^3
Now density = mass/volume
2.7g/cm^3 = mass/280cm^3
2.7g/cm^3 x 280cm^3 = mass/280cm^3 x 280cm^3
= 750g of Aluminum

3. Burns from boiling water can be severe, caused by the transfer of energy from the boiling water to the
skin as the water cools to body temperature. How much heat (kJ) is transferred from the from 15.0g
of boiling water at 100.0°C as it hits the skin and cools to 37.2°C?
Answer:
Q = 3937.56 J
Explanation:
Heat transferred due to change in temperature is given by :
[tex]Q=mc\Delta T[/tex]
c is the specific heat of water, c=4.18 J/g-°C
We have, m = 15 g, [tex]T_i=100^{\circ} C\ \text{and}\ T_f=37.2^{\circ} C[/tex]
So,
[tex]Q=15\times 4.18\times (37.2-100)\\Q=-3937.56\ J[/tex]
Hence, 3937.56 J of heat is transferred.

You have an atom with a mass number of 100 with 85 neutrons. What is this
element?
Answer:
phosphorus i believe
Explanation:
in order to find the atomic number you minus the mass number from number of neutrons then just look it up in a periodic table
The mass number of the atom is 100 and number of neutrons is 85. Then, number of protons is 15. Then, element with 15 protons and 15 electrons is phosphorous.
What is mass number ?An atom is composed of subatomic particles electrons, protons and neutrons. Protons and neutrons are located inside the nucleus. The mass number of an atom is sum of number of protons and neutrons.
The number of electrons in an atom in its neutral state is called its atomic number. In a neutral atom, the number of electrons and proton are the same.
Give the mass number = 100
no.of neutrons = 85
no.of protons = 100 -85 =15
no.of electron = 15
Thus, atomic number = 15.
The element with atomic number of 15 is phosphorous (P).

Which statement is incorrect concerning the formation of ionic compounds?
a Halogens tend to form anions with a charge of -1.
b. Alkali metals tend to form cations with a charge of +1.
c. Metals tend to form cations, while nonmetals tend to form anions.
d. Transition metals tend to form cations with a charge of +3.
e. Noble gases tend not to form ionic compounds.
Answer:
d. Transition metals tend to form cations with a charge of +3.
Explanation:
Which statement is incorrect concerning the formation of ionic compounds?
a. Halogens tend to form anions with a charge of -1. TRUE. Halogens have 7 electrons in their valence shell, so they tend to gain 1 electron to fill their octet.
b. Alkali metals tend to form cations with a charge of +1. TRUE. Alkali metals have 1 electron in their valence shell, so they tend to lose 1 electron to fill their previous octet.
c. Metals tend to form cations, while nonmetals tend to form anions. TRUE. Metals have low electronegativity while nonmetals have high electronegativity.
d. Transition metals tend to form cations with a charge of +3. FALSE. Transition metals form cation with numerous charges.
e. Noble gases tend not to form ionic compounds. TRUE. Noble gases are very stable because their octet is full.
