Answer:
Following two compounds have Hydrogen Bond Interactions;
1) CH₃(CH₂)₂NH₂ (Propan-1-amine)<span>
2) </span>CH₃(CH₂)₂NH(CH₂)₄CH₃ (N-propylpentan-1-amine)
Explanation:
Hydrogen Bond Interactions are formed between those molecules which has hydrogen atoms covalently bonded to most electronegative atoms like Fluorine, Oxygen and Nitrogen. This direct attachment of Hydrogen to electronegative atom makes it partial positive resulting in hydrogen bonding with neighbor's partial negative most electronegative atom. So, in above selected compounds it can be seen that both compounds contain hydrogen atoms directly attached to Nitrogen atoms, Therefore, allowing them to form Hydrogen Bonding Interactions.
Answer: The answer is Fossil A is younger than the index fossil.
Explanation: Because it’s the newest layer
277.79 atm is the calculated gas pressure.
The ideal gas is a fictitious concept used to study how real gases behave by comparing them to their deviations. The pressure-temperature rules are followed by an ideal gas.
177 atm is the initial pressure. The starting temperature is 298 K (25 °C = 25 + 273 °C).
195°C = 195+273
= 468K is the final temperature.
The pressure temperature relation illustrated below can be used to get the final pressure.
P1/T1 = P2/T1
= P1T2/T1
= 177 atm 468 K /298 K
= 277.97 atm
The final pressure is therefore 277.97 atm.

NO, It Isn't
Ideally a population in Hardy Weinberg equilibrium should hold true to the following equation for genotypic frequencies of an allele;
P² + 2pq + q² = 1
Explanation:
We are provided with allelic frequencies hence we can derive the genotypic frequencies; (CR allele: p = 0.6 Frequency of the CW allele: q = 0.4)
P² = 0.6 ^2 = 0.36
2pq = 2 * 0.6 * 0.4 = 0.48
q² = 0.4 ^ 2 = 0.16
Lets find out if all add up to as supposed to;
0.36 + 0.48 + 0.16 = 1
Converting to percentages is easy – just multiply by 100
- 36 % CRCR
- 48% CRCW
- and 16 % CWCW
The population provided is not in equilibrium because their percentages vary widely to that the expected Hardy Weinberg's equilibrium percentages. This could be attributed to factors like;
- Migration
- Mutations,
- There is natural selection in progress in the population
- There is gene flow
