Design an experiment where you would determine how quickly lactaid works to break down milk sugar

xxMikexx [17]

Answer:

Gather 11 Cups And then fill each cup with 5 ounces of whole milk, next is take the first cup to add a known quantity of lactaid. As A Control take another cup and do not add any lactaid. After 1 Minute, pour a known quantity of benedicts into cups of milk. Record the colour ( blue is the least amount of glucose progressing to green, then yellow, orange, red and brick/red brown). Take another cup of milk and then add the lactaid and wait for 5 minutes... Next is add the benedicts. Record the color, repeat steps 7 - 10 adding 5 minute each time until there are no cups left ( 15 minutes, 20,25,30,35,40,45) .

For the last is graph the data and forms conclusions ..

This is the right answer.
Hope it helps.

Fault trees are an approach to hazard analysis that, for each identified hazard, break down that hazard to find how that hazard

Alexus [3.1K]

Hazards are placed at the root of the tree and determining the cause of the hazard is the correct option for the following hazard analysis questions.

Fault Tree Analysis (FTA) explores how selected “top” faults (abnormal conditions) or fault events such as accidental/unwanted releases of hazardous materials can be resolved to their causes. Hazard analysis is defined as the process of gathering and interpreting information about the hazards and conditions leading to their existence in order to determine what is food safety related and must be addressed in the HACCP plan. Hazard analysis is used as the first step in the risk assessment process. The result of hazard analysis is the identification of different types of hazards. A hazard is a potential condition that may or may not exist.

Consider the following hypothetical population and compute the statistical measures below: #births = 50,000; #deaths = 10,000; #

777dan777 [17]

Answer:

The birth rate refers to an average number of births in one year per thousand individuals in the population at mid-year.

BR = (total birth in an annum / total population in mid year) * 1000

BR = (50000 / 1000000) * 1000 = 50

Death rate refers to an average number of death in an annum per thousand individuals in a population at mid year. Thus,

DR = (total death / total population in mid year) * 1000

DR = (10000 / 1000000) * 1000 = 10

Annual population growth rate or APGR is calculated as:

APGR = (Birth rate - Death rate) / Death rate

APGR = (50 - 10) / 10 = 4.0 %

Doubling time is the whole sum time needed for a population to get double in size. It is calculated as DT = ln (2) / growth rate

70 / 4.0 = 17.5 years

Thus, population will get double in 17.5 years.

Adjusted (true) growth rate is equal to APGR + (NMR / Death rate)

And NMR = [(immigrants -emigrants) / total population] * 1000

NMR = [(5000 - 20000) / 1000000] * 1000 = -15

Thus, Adjusted (True) growth rate = 4.0 + (-15 /10) = -6%

The adjusted (true) doubling time = ln (2) / Adjusted growth rate

= 70 / -6 = -11.66

This negative sign shows that it will never get double in such situation.
