Answer:
hope this helps! :)
Explanation:
While humans and many other animals determine sex genetically, many reptiles and some fish use the incubation temperature of the eggs to set the gender of their offspring. This means that changing global temperatures could alter the ratio of sexes produced, making it harder for these animals to find mates

Answer:
D. Separation by melting point
Answer:
n = 0.072 mol
Explanation:
Given data:
Volume of gas = 3.80 L
Temperature of gas = 320 K
Pressure of gas = 0.496 atm
Number of moles of Ar gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will put the values.
n = PV/RT
n = 0.496 atm ×3.80 L / 0.0821 atm.L/ mol.K × 320 K
n = 1.88 /26.27 /mol
n = 0.072 mol
