Biology
1 answer:
vesna_86 [32]4 years ago
8 0

Answer: 20 ± 11.32

Explanation: <u>Confidence</u> <u>Interval</u> (CI) is an interval of values where there is a % certainty the true mean value lies in. For example, a 95% CI means there is a 95% certainty the true mean value lies in the interval.

For the data set 2, z-value for 95% confidence interval is z = 1.96

Formula to calculate CI is

x ± z\frac{s}{\sqrt{n} }

where

x is mean

z is z-value

s is standard deviation

n is the sample number

Then:

20 ± 1.96\frac{10}{\sqrt{3} }

20 ± 1.96\frac{10}{1.7320}

20 ± \frac{19.6}{1.7320}

20 ± 11.32

The 95% CI is 20 ± 11.32, which means there is a 95% certainty the true value is between 8.68 and 31.32.

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs)
ch4aika [34]

<u>Answer:</u>

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism

The reactive oxygen species that are given out by the mitochondria during cellular respiration are the major cause of aging. Though this has a lot of negative effects but this also has a small amount of positive effects such as the start of angiogenesis or cell proliferation.

1. How much of downtown boston was original land? Where did the rest come from?
Hatshy [7]

History of Boston is described below.

Explanation:

  • When workers cut down Copp's hill the only thing they left untouched was the old three-acre burying ground. The city built a retaining wall around the graveyard to prevent it from eroding. In 1814, the Boston and Roxbury Mill Corporation built the Boston & Roxbury Mill Dam across the back bay
  • Originally called Tremontaine for the three hills in the area, the Puritans later changed the settlement's name to Boston, after the town in Lincolnshire, England, from which many Puritans originated.
  • South Boston, which was front and center in the battle, is no longer that close-knit old school “tough-as-nail” Irish Catholic enclave. “Southie,” as it is still fondly referred to, houses the world today flaunting some of the best restaurants and expensive housing in the city
  • Boston was founded in 1630 by English Puritans fleeing religious persecution. On 29 March 1630 a fleet of 11 ships carrying 700 people sailed from England to Massachusetts. They were led by John Winthrop (1588-1649). At first the people settled at Charlestown, which had been founded the year before.
  • Much of Boston's coastline is man-made land. The original shoreline, from 1630, is visible in dark green on this map. Land made between 1630 and 1995 is light green.Boston is a safe city, but as with any major city, you should take the usual safety precautions. Stay in well-populated areas, travel with others, especially at night, and keep track of your belongings. The tourist areas in Boston are generally safe, but some areas deserve mention.
