You can't use it because the living cells won't be able to handle the high vacuum conditions.
Hope this helped ;)

Which of the following organisms is most likely to spoil a food such as salted fish? Choose one: A. Cenarchaeum symbiosum B. The
Lubov Fominskaja [6]

Answer:

C Halobacterium species

Explanation:

ThIs is because this species of bacteria thrive well in high salt concentrations; and will  be inactive in a low  salt concentration medium.They are known  as Hallophilic Organisms. (salt organism)s

They are  rod-shaped, motile organisms , which  reproduced by binary fission,live in saline lakes, with  the cell bounded by a single layer of  plasma membranes.They  contain beta-caroteen pigments. it is this that is responsible for their red coloration.When this pigment is extracted, is  used in food dye. giving food red coloration.

In addition, Halo. Bacteria contain some  enzymes that can break dowm organic  molecules to simplest forms. These are  Degredative enzymes.(e.g Lipase , Amylases). it is this  feature that aids their application    for aiding  the  process of  fermentatio<u>n of salty foods</u>, and also aiding  of <u>coffee processing during production. </u>

<u>Since this is called a salty bacterium, and its enzymes will be most active in high salty concentrations, then option C is the correct answer.</u>

How are photosynthesis and cellular respiration related
pishuonlain [190]

Answer:

b. they are both performed by plants.

Explanation:

Photosynthesis is the process of transforming light energy into chemical energy by green plants. During the process, the plants make use of solar energy in order to convert carbon dioxide and water into carbohydrates. And also releases oxygen into the atmosphere. Photosynthesis is called primary production because the food produced by the process makes the base of most ecosystem food chains. It stores energy at the bottom level of the food chain.

All animals are dependent on photosynthesis because animals depend on glucose as their energy source, but they are incapable of producing it on their own, so they must depend on plants in order to get glucose.

And also the oxygen that animals breathe is released during photosynthesis.

Cellular respiration:

It is the process through which living cells degrade glucose molecules, releasing energy, and store it as ATP molecules. Overall, glucose and oxygen react to generate carbon dioxide and water in this three-stage process.

nekit [7.7K]
Not necessarily, the equilibrium does not necessarily mean that the partial pressures are equal-- to explain this, you could look up the equilibrium constant of partial pressures. They are ratios, and not just equal partial pressures!
