Yesterday student used Gram stain to indentify any bacterias from nutrient agar using microscope. Instead he took several pictures. Can you at least indentify 1 possible specie of bacteria from these 6 pictures? In answer don't forget to mention number and side of a picture!

Write the function of each component of TBE and TAE buffer along with individual molarity from given mass

T= Tris

A= Glacial acetic acid

E= EDTA

B= Boric Acid

10x TAE Recipe

For 1L of 10x solution,

• 48.5 g tris

• 11.4 mL glacial acetic acid

• 20 mL 0.5M EDTA (pH 8.0)

TBE Buffer 10x Stock Recipe

• 108 g tris base

• 55 g boric acid

• 900 ml double-distilled H2O

• 40 ml 0.5 M EDTA solution (pH 8.0)

Adjust volume to 1 L.

Construct a 1-page informative poster to market ONE commercially

important breed/strain selected out of EACH of the livestock species listed

below.

• Beef Cattle

• Dairy Cattle

• Goats

• Sheep

• Broiler Chickens (Specific strain)

• Layer Chickens (Specific strain)

The breed/strain must be one which is considered suitable for production in

the semi-arid bushveld such as the Vhembe district. Among other important

details, your poster must include details on productivity, product quality

and breed/strain adaptability to justify the breed/strain suitability for the

ecosystem, markets and the specified production system & the environment.

Hi,

I am writing a lab report, however, to explain the results I got from the experiment I need to change the units. I am a bit confused about this. Would you be able to help with this please and show me how to convert it and not just the answers? I have got only until the end of this month.

Thank you.

WBC (10³/mm³) : 6.7 x 10³/mm³

LYM% (percentage, %) : 19.7

MON% (percentage, %) : 4.1

GRA% (percentage, %) : 76.2

LYM# (absolute, 10³/mm³) : 1.30 x 10³/mm³

MON# (absolute, 10³/mm³) : 0.20 x 10³/mm³

GRA# (absolute, 10³/mm³): 5.20 x 10³/mm³

RBC (10⁶/mm³): 4.50 x 10⁶/mm³
