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

Steve, a 32-year-old man, suffers from liver damage. Clinical examination reveals that it was caused by a toxin produced by a ce
Ymorist [56]

Answer: Aspergillus

Explanation:

Aspergillus is the fungal species which is highly aerobic in nature. It is found in the oxygen rich environment. This fungal species grows as molds typically over the substrate, as a result of high oxygen tension. The molds are toxic in nature. It grows over certain fruits, vegetables like apricots, peanuts, onions and grapes. It is the common contaminant of food. It is responsible for causing liver cirrhosis.

On the basis of the given situation this can be said that Steve is infected by Aspergillus.

What factors limit the size of a cell?
vesna_86 [32]

Answer:

Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.

Explanation:

I hope this helps you!
