urbanbreathnyc.com: They will certainly have various beak pointiness due to the fact that their proteins because that beak pointiness are different so the proteins will attach in various ways.

See more: The Electric Resistance In A Length Of Wire Is Doubled When The Wire Is _________.

Explanation:

Based on the information listed in the question, it should be detailed that the pointiness of the birds beak will be various as a an outcome the distinction of your proteins for beak pointiness so the protein will affix in different ways.

Assuming the 2 junco birds have thesame proteins in their cells for beak

pointiness, they"ll have thesame mine pointiness.

A rapid sand filter has actually a loading rate of 8.00 m/h, surface dimensions that 10 m ´ 8 m, an reliable filtration rate of 7.70 m/h.
galben <10>

urbanbreathnyc.com:

Explanation:

given data

loading price = 8.00 m/h

filtration price = 7.70 m/h

dimensions = 10 m × 8 m

filter cycle duration = 52 h

time = 20 min

to discover out

flow rate and also volume the water is provided for ago washing to add rinsing the filter

solution

we take into consideration here production effectiveness is 96%

so here circulation rate will certainly be

flow price = area × rate of filtration

flow price = 10 × 8 × 7.7

flow rate = 616 m³/h

and

we know earlier washing typically 3 come 5 % of full volume of water per cycle for this reason

volume of water is = 616 × 52

volume of water is 32032 m³

and

volume the water of back washing is = 4% the 32032

volume the water of ago washing is 1281.2 m³
