Answer:-
Nuclear DNA is inherited from all ancestors. But mitochondrial DNA is inherited from a single lineage. The DNA inside of mitochondria (called mtDNA) unlike DNA inside the nucleus, comes from only mothers.
It is not a mixture of our parent’s DNA, and each person’s mtDNA is nearly identical to his or her mother’s mtDNA.
Thus only nDNA being more unique is more useful for identifying in forensics. In cases where nDNA is not sufficient, mtDNA is used.
A) 4400 kj of heat released into surroundings
<h3>Further explanation</h3>
Reaction
C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O, the ∆H is –2200 kJ
Reaction exothermic( ∆H=-, released heat to surrounding) and for combustion of 1 mole of C3H8
So for two moles of C3H8, the enthalpy :
Answer:
Fermentation is where all alcohol is created, distillation is where the alcohol is separated and removed. In order for fermentation to occur, two things are needed: a raw material in liquid form that contains sugar, followed by the addition of yeast.
Before it is released it as potential energy and after it has been released it transforms into kinetic energy.
Answer:
<h2>0.2 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>0.2 m/s²</h3>
Hope this helps you
