Answer:
The most accurate measurement is 2.829 cm.
Explanation:
We can round the decimals to a certain accuracy in order to make further calculations easier.To round a number to the nearest hundredth ,check the next place value to the right (the thousandths). If it's less than 5, remove all the digits to the right. If the place value is 5 or greater than 5, just add 1 to the previous digit (the hundredths place digit) and drop all other digits to the right.
In other words, to round off a decimal number, the procedure is as follows; if the digit to the right of the required number is a 5 or greater, add 1 to previous digit and drop all the remaining digits. If the required number is less than 5, do not change the previous digit and remove all the remaining digits.
Here, a piece of metal with a length of 2.83 cm was measured using four different devices. The obtained measurements are 2.837 cm, 2.829 cm, 2.812 cm and 2.805 cm.
Thus, the first measurement 2.837 cm can be round off to 2.84 cm. The second measurement 2.829 cm can be round off to 2.83 cm. The third measurement 2.812 cm can be round off to 2.81 cm and the fourth measurement 2.805 cm can be round off to 2.81 cm.
So the most accurate measurement is the second one, 2.829 cm which can be round off to 2.83 cm.
Answer:
Voltaire was a French Enlightenment writer, historian, and philosopher, who attacked the Catholic Church and advocated freedom of religion, freedom of expression, and separation of church and state.
IV only
Plate IV will only have the trangenic E Coli hence will have the highest percentage of bacteria that are expected to produce insulin.
Explanation:
The transgenic <em>E. coli </em>will have taken up the plasmid with the insulin and <em>amp</em> genes hence they will be able to survive and grow in amplicilin antibiotic.
In plate IV, the wild type <em>E. coli</em> will be eliminated by the antibiotic (because they do not have the gene for resistance) hence providing no competition for resources, in the agar, with the transgenic <em>E coli</em>. This will ensure optimal growth for the transgenic <em>E coli</em> even, than in plate III, producing highest percentage of insulin.

True. If the diameter of the afferent arterioles leading to the glomerulus increases due to vasodilation, which ultimately increases the net filtration pressure.
The filtration of blood occurs in the kidney, an excretory organ. The kidney is composed of numerous small units called nephrons, which is responsible for the blood filtration.
Glomerulus is part of nephron and the glomerular filtration occurs in the renal corpuscle of the kidney. This process is driven by hydrostatic and colloid osmotic pressure.
These pressures are collectively called net filtration pressure, which is influenced by the diameter of afferent arterioles.
If the arterioles constricts, net filtration pressure will decrease and if arterioles dilates, net filtration pressure will increase. This mechanism is regulated by neural, renal and hormonal regulation.
