You can use the HWE (Hardy Weinberg Equilibrium) equations :

p + q = 1

p^2 + 2pq + q^2 = 1

If the allele combinations do not equal one after a while, evolution has occurred.

Explain how nuclear and chemical reactions differ in terms of how they are balanced. (PLEASE ANSWER ASAP THIS NEEDS TO BE TURNED
Tcecarenko [31]

Explanation:

(1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.

HELP PLSSSSS!!
11Alexandr11 [23.1K]

Answer:

68133080.02 g

Explanation:

I believe that the question is to find the mass of air in the room and not the molar mass of air since the molar mass of air was already given in the question as 28.97 g/mol.

Now, if 1 mole of a gas occupies 22.4 L

x moles of air occupies 52,681,428.8 Liters

x = 1 * 52,681,428.8 /22.4

x = 2351849.5 moles of air

Now, number of moles = mass/ molar mass

but molar mass = 28.97 g/mol

2351849.5 = mass/28.97

mass = 2351849.5 * 28.97

mass = 68133080.02 g

Imagine that you are playing a game of Clue in which Mrs. White is killed in the conservatory. You have a device in each room to
myrzilka [38]

Answer:

  • <u><em>Mr. Plum</em></u><em> killed Mrs. White.</em>

Explanation:

<u>1) Wavelengths for the different light colors (visible light) and related character:</u>

Color  Wavelength          related character

Violet  380–450 nm  ← Professr Plum

Blue  450–485 nm  ← Mrs. Peacock

Cyan  485–500 nm  

Green  500–565 nm  ← Mr. Green

Yellow  565–590 nm  ← Colonel Mustard

Orange  590–625 nm  

Red  625–740 nm  ← Miss Scarlet

<u>2) At the time of the murder, the spectrometers recorded:</u>

a) In the <em>dining room</em>: <em>520 nm</em>.

520 nm is in the range 500 - 565 nm, which is the range for green color, so <em>Mr. Green</em> was in the dining room and is no more a suspect.

b)<em> In the lounge and study: lower frequencie</em>s.

Since frequency and wavelength are inversely related, the wavelengths in the longe and study have to be of <em>yellow and red</em> colors, which are the only two with longer wavelengths from the option given.

Then, <em>Mustard and Scarlet</em> are not criminal.

c)<em> In the library: the second shortest wavelength of the five recorded. </em>

<em />

The second shortest wavelength, as per the table, is that of <em>blue </em>color. So, <em>Mrs. Peacock</em> is not the killer.

The only left option is violet, so Mr. Plum is the only who could be at the conservatory and he is the killer.
