The microbial organisms that cause food to spoil are generally the same that cause food borne disease A. True B. False

Nataly [62]

Answer: True

Explanation: There are some microorganism tend to spoil the food and produce the bad odor, spoilage etc in the food which may lead to disease like food borne disease.This disease leads to the serious health conditions or sometimes death.Example of such bacteria are-Serratia, Lactobacillus etc. These microbial organism infect the food and thus lead to food borne disease . So,the statement given is true.

a rural kansas watershed that is ungauged has an area of 475 acres and a main channel length of 6870 feet with an average slope

dlinn [17]

Answer:

$\mathbf{Q_p =682 \ \ ft^3/s}$

Explanation:

Given that:

Area = 475 acres

The length of the channel (L) = 6870 feet

The average water shield slope (S) = 100 feet/mile

Since; 1 mile = 5280 feet

Burst duration D = 15 min

∴

100 feet/mile = 100/5280

The average water shield slope (S) = 5/264

Using hydrograph method:

The time of concentration $t_c = 0.0078L^{0.77} S^{-0.385}$

where;

L = 6870

S = 5/264

$t_c = 0.0078(6870)^{0.77} (\dfrac{5}{264})^{-0.385}$

$t_c =32.34$ min

Since 60 min = 1 hour

32.34 min will be (32.34*1)/60

= 0.539 hour

Lag time $T_l = 0.67\times t_c$

$T_l = 0.67\times 32.34$

$T_l = 21.6678\ min$

The time to peak i.e

$T_p = \dfrac{D}{2}+ T_L \\ \\ T_p = \dfrac{15}{2}+ 21.6678 \\ \\ T_p = 29.168 \ min$

$T_r = \dfrac{T_p}{5.5} \\ \\ T_r = \dfrac{29.1678}{5.5} \\ \\ T_r = 5.30 \ min$

Since D = 15 min is not equal to $T_r$ , then we hydrograph apart from $T_r$ duration lag time.

Then;

$T_p \ ' = T_p + \dfrac{D-t_r}{4} \\ \\ T_p \ ' = 29.168 + \dfrac{15-5.30}{4} \\ \\ T_p \ ' = 31.593$

Now, we need to determine the peak discharge $Q_p$ by using the formula:

$Q_p = \dfrac{484 \times A}{T_p \ '}$

where

484 = peak factor

Recall that A = 475 acres, to miles, we have:

A = 0.7422 mile²

$T_p \ ' = 31.593/60$

∴

$Q_p = \dfrac{484 \times 0.7422}{\dfrac{31.593}{60}}$

$\mathbf{Q_p =682 \ \ ft^3/s}$

What trends do you notice in how lines of longitude are measured as you travel east or west of 0° longitude?

aev [14]

The prime meridian is 0 degrees longitude. As you go east from the prime meridian, the longitude increases to 180 degrees. As you go west from the prime meridian longitude increases to 180 degrees.

Which of the following sites has volcanism related to a hot spot or divergent margin? A is on an island arc, B is in the Andes,

WITCHER [35]

Question Options:

A. A and B

B. B and C

C. C and D

D. A and C

E. B and D

Answer: C and D. C is near Hawaii, D is along a mid-ocean ridge

Hotspot in geology is the surface manifestation of a plume that rises from deep in the celestial body's mantle.

Divergent margins also known as rift zones, shield volcanoes tend to form as two oceanic plates pull slowly apart and magma effuses upward through the gap.

The sites based on history that has volcanism related to a hot spot or divergent margin are Hawaii and the mid-ocean ridge. Hawaiian volcanoes within the Pacific Plate are caused by anomalous volcanism.
