Answer:
Yes
Explanation:
They are a unique type of eukaryote because they lack an important organelle: mitochondria. Mitochondria are essential for producing cellular energy in most eukaryotic cells. However, due to its habitat, it is able to acquire energy from a process called sulfur mobilization.
They are significant because they challenge the idea that eukaryotes need mitochondria to be classified as eukaryotic. However, they have other membrane-bound organelles such as a nucleus and Golgi apparatus, meaning they remain eukaryotic.
Research suggest they lost their mitochondria over time, rather than never having had them throughout their ancestry.
Because of all these reasons, they still meet the definition of a eukaryote.
Answer:
25.7 kJ/mol
Explanation:
There are two heats involved.
heat of solution of NH₄NO₃ + heat from water = 0
q₁ + q₂ = 0
n = moles of NH₄NO₃ = 8.00 g NH₄NO₃ × 1 mol NH₄NO₃/80.0 g NH₄NO₃
∴ n = 0.100 mol NH₄NO₃
q₁ = n * ΔHsoln = 0.100 mol * ΔHsoln
m = mass of solution = 1000.0 g + 8.00 g = 1008.0 g
q₂ = mcΔT = 58.0 g × 4.184 J°C⁻¹ g⁻¹ × ((20.39-21)°C) = -2570.19 J
q₁ + q₂ = 0.100 mol ×ΔHsoln – 2570.19 J = 0
ΔHsoln = +2570.19 J /0.100 mol = +25702 J/mol = +25.7 kJ/mol
Answer:
<em>Dry suction chest tube system</em>
Explanation:
<em>The dry suction drains that are self-regulating today use a small, adjustable regulator installed into the drain. </em>
So long as there is enough air flow from the suction of the wall (that will be shown on the drain) it will respond correctly to changes in the pressure of the source or the patient to retain suction at the drain level.
It's also a quiet mode of activity.
Answer:
c. law
Explanation:
Law -
It is type of statement , which helps to explain certain observations , in the form of mathematical relationship or verbal statements , is referred as a law .
Law is a widely accepted information , which can get altered by some new inventions or exception.
A law is stated in words as well as in the form of some mathematical relationships or equations.
Hence , from the given information of the question,
The correct option is c. law .
