I would go with hypothesis because I never heard any of the other answers in Bio and a hypothesis is an educated guess so it means what you already know and it’s an observation (I hope this helped!!)
Answer:
0.36g
Explanation:
Given parameters and conversion to standard unit
To solve this problem we must assume ideality
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = 
= 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n = 
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = 
= 0.01mole
So,
Mass = 0.01 x 32 = 0.36g
Answer:
I believe they would be h_i_n_g_e.

The Fingers can only move so much unlike the thumb.
Among the most frequently used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known standard sequences are estimated using phylogenetic trees.
<h3>What is a phylogenetic tree?</h3>
Among the most commonly used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known reference sequences are estimated using phylogenetic trees.
A phylogenetic tree is a diagram that depicts the evolutionary relationships between organisms or groups of organisms.
Scientists consider phylogenetic trees to be evolutionary hypotheses because the proposed relationships cannot be confirmed in the past.
Thus, every individual of same species are related to each other, so scientists can analyze another specimen from the same species.
