Answer:

The correct answer is - option C.

Explanation:

Iridotomy is a procedure which is used to treat condition like narrow angle glaucoma and chronic open angle glaucoma, angle closure glaucoma and other chronic glaucoma conditions. In many cases iridotomy is needed to be performed immediately.

Iridotomy procedure in this case is helpful as it is improve the outflow of the drainage which is causing the intraocular pressure which is 50 mm in this case and also will help in reducing the pain.

Thus, the correct answer is - option C.

You do a serial dilution in the same manner as the one in the video. A plate with a sample volume of 10-6 mL produced 43 colonie
8090 [49]

Answer: 43 x 10^6  CFU.

Explanation:

Plate count is a method used to determine the number of viable microorganisms in a sample. When the bacterial concentration is high, serial dilutions are carried out in a 1:10 sequence. <u>Then, the dilutions are successive dilutions keeping the dilution factor constant at each step</u>. Small aliquots of these dilutions are seeded in medium contained in a Petri dish where the bacteria grow forming colonies. Then the plates are incubated and colonies develop both within the agar and on the surface.

If the concentration of the seeded aliquot is too high, the bacteria will grow too much and it will not be possible to distinguish the colonies. <u>However, if the concentration is very low, the number of colony forming units (CFU) may be very low and thus can be counted</u>.

Colony forming units are calculated:

CFU = Number of colonies / (volume seeded on the plate * dilution).

The dilution is 10^-6, the number of colonies counted is 43, and usually the volume plated is 0.1 mL, so we replace that in the equation:

CFU= 43 / (0.1 mL * 10^-6)

CFU= 43000000 = 43 x 10^6

Which factors of Earth's position would contribute to long-term climate change?
vazorg [7]

Answer:

A) its elliptical orbit and tilt on its axis  

Explanation:

Earth revolves around the sun in an elliptical path. Its axis is tilted to about 23.5° from the vertical.

These two factors determine the global climate on the Earth.

Due to elliptical orbit, the earth is sometimes closer to sun than the rest of the time. When it is closer the global temperature rises by 5 degrees. Due to the tilt of the Earth, seasons occur. The hemisphere which points towards the sun has summers where as which points away has winters.

Thus, the long-term climate change is effected by elliptical orbit and tilt of the axis.
