Answer:

5 * 10^{10}

Explanation:

The question is not complete. Remaining part of the question is as follows - Minimal growth medium for bacteria such as E. coli includes various salts with  characteristic concentrations in the mM range and a carbon source. The carbon source is  typically glucose and it is used at 0.5% (a concentration of 0.5 g/100 mL). For nitrogen,  minimal medium contains ammonium chloride (NH4Cl) with a concentration of 0.1 g/100 mL

How many cells can be grown in a 5 mL culture using minimal medium before the medium exhausts the carbon?

Solution -

We will first find the mass concentration of 0.5 g/100 mL of solution.

\frac{0.5}{100} gram per ml of glucose

The chemical formula of glucose is C_6H_{12}O_6

The molecular weight of glucose molecule is 180 grams per mole

Now, we will find the number of moles of glucose in a 5 ml medium -

\frac{\frac{0.5}{100} * 5}{180} \\1.39 * 10^{-4} mole

The number of carbon atom in each glucose molecule is equal to six, thus, number of minimal carbon mole is equal to

1.39 * 10^{-4} * 6\\= 8.34* 10^{-4}mole

Number of carbon atoms is equal to

8.34* 10^{-4} * 6.023 * 10^{23}\\= 5 * 10^{20}\\ Carbons

One bacteria has 10^{10} carbon molecule.Thus, 5 ml medium will have 5 * 10^{10} bacteria

What condition may arise if the pituitary glands is not producing enough growth hormones?
vesna_86 [32]
Growth Hormone deficiency is a medical condition wherein the pituitary gland is not able to produce enough growth hormones also known as somatropins. This can be acquired either in childhood or adulthood. This condition is called hypopituitarism. Hope this is the answer that you are looking for.

Studentka2010 [4]

Answer:

evolution

Explanation:

For example, scientists believe that monkeys have evolved to become humans.

This clearly has happened over many millions of years.

Monkeys look really different from humans (don't you think!?).

This was just a random example that came to my head.

Hope this helps.

Red blood cells are placed in water that has been distilled so there are no solutes dissolved in the water. Are the red blood ce
Thepotemich [5.8K]


Red blood cells will swell and burst.

The reason behind this is that red blood cells are okay when they are in the plasma (the watery part of the blood) because the solutes in plasma are so  well balanced that plasma is rendered isotonic. An isotonic solution is a type of solution that has the same salt concentration as its surrounding environment and thus the substances around it e.g. cells neither gain nor lose water. In the blood plasma, the red blood cells neither lose nor gain water  and so they remain intact.

However distilled water is hypotonic (has less or no solutes) and therefore osmosis will take place when red blood cell which have a higher solute concentration are placed in it. Water molecules will leave the distilled water and pass into the red blood cells through the semi-permeable membrane of the cells in an attempt to equalize the difference in osmotic pressure on either side of the membrane. In so doing, water will accumulate in the cell which will then swell to capacity and ultimately burst.

Dmitry_Shevchenko [17]

Answer:

This question includes some errors, the question should be written as:

The medulla oblongata controls the contraction and relaxation of the ______ causing the lungs to inflate and deflate during breathing.

Although there are no options, the answer is generally RESPIRATORY MUSCLES i.e. diaphragm and intercostal muscles

Explanation:

Breathing is an involuntary action required to take place in order to get oxygen into the system and carbon dioxide out of the system. However, the process of breathing is neurally controlled by brain portion called RESPIRATORY CONTROL CENTERS.

The Medulla oblongata located in the hindbrain is one of the two respiratory control centers (the other being the PONS). The medulla sends nerve signals to the muscles responsible for bringing about the ventilation process i.e. the DIAPHRAGM and INTERCOSTAL MUSCLES.

This nerve impulse brings about the contraction of the diaphragm, which is the major respiratory muscle, and intercostal muscle causing the lungs to inflate and allow the entry of oxygen-containing air. On the other hand, it also brings about the relaxation of these muscles causing the lungs to deflate allowing the expelling of air.
