The concentration of N2 in blood at 37 °C (body temperature) and atmospheric pressure (partial pressure of N2 = 0.80 atm) is 0.0
devlian [24]

Answer:

volume  = 0.285 L

Explanation:

Henry constant is given as

Henry constant  =  \frac{C}{P}

Where C  is concentration

P is atmospheric pressure

Henry\ constant = \frac{0.00056}{0.80} = 0.0007 M/atm

when atmospheric pressure 4 atm

solubility = K_H\times P

              = 0.0007 \times 4 = 0.0028 M

In 5 litere blood , moles of N_2 = Molarity \times volume

                                                     = 0.0028 \times 5 = 0.014

At surface moles  = 0.0056 \times 5 = 0.0028

Moles of N_2 release = 0.014 - 0.0028 = 0.0112

Mass of N_2 = 0.0112 \times 28 = 0.314 g

T = 37 + 273 = 310 K

VOLUME = \frac{nRT}{P}

= \frac{0.0112\times 0.0821\times 310}{1}

volume  = 0.285 L

Why is it important to have both negative and positive feedback loops in the body
ELEN [110]

Answer: positive feedback loops enhance or amplify changes. this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes. this tends to hold a system to some equilibrium state making it more stable.

When did Isaac Newton start learning facts about Force and Motion?
Blababa [14]

Answer:

He developed the theories of gravitation in 1666, when he was only 23 years old. Some twenty years later, in 1686, he presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis." The laws are shown above, and the application of these laws to aerodynamics are given on separate slides.

An enhancer may increase the frequency of transcription initiation for its associated gene when… (indicate true or false for eac
Olenka [21]

Answer:

it is located 1000 nucleotides upstream of the gene’s core promoter - true

it is located 1000 nucleotides downstream of the gene’s core promoter- true

it is in the gene’s coding region - False

Explanation:

These enhancers are located 50 or more kilobases from the promoter they controlled upstream from a promoter, downstream from a promoter within an intron, or even downstream from the <u>final exon</u> of a gene which can be thousands of bp away from the gene's core promoter and can also occur thousands of nucleotides away from the gene's core promoter needing the activity of a DNA -bending protein that binds to the enhancer changing the shape of the DNA and allow interactions between the activators and transcription factors.
