Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the
gregori [183]

Answer:

A. 14.59

Explanation:

Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.

Next, we have to know that to round a number;

* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.

* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit

Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant

Hence, 14.587020 will be:

= 14.587020

= 14.58700

= 14.59000

We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right

Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59

When the sun impacts weather, an interaction with the __________ takes place.
Nadya [2.5K]

Answer:

Hydrosphere

Explanation:

When the sun impacts weather, an interaction with the hydrosphere takes place. The hydrosphere is the part of the earth that is enveloped by water. Water exists in three different forms on the earth based on diverse factors.

Weather is the atmospheric condition of a place over a short period of time.

The sun causes the warming of the earth surface which leads to evaporation of water vapor into the atmosphere.

This water in the atmosphere is forms rainfall, one of the elements of weather.

The sun causes an impact on weather by causing evaporation of water into the atmosphere.

This interaction takes place in the hydrosphere.

Scurvy is a disease that until the nineteenth century was common among sailors and others whose diets were deficient in vitamin
alina1380 [7]
<h2>Scurvy </h2>

Explanation:

(a) Collagen is the major structural component of cartilage,bones and tendons

  • The basic unit of collagen is tropocollagen and each tropocollagen consists of three coiled left handed polypeptide chains called α chains
  • Generally each α chain consists of a repeating tripeptide sequence called: G-X-Y
  • Here G represents glycine; X represents proline and Y represents hydroxyproline
  • Rigidity of collagen molecule is due to presence of proline and hydroxyproline
  • Hydroxylation of proline is catalysed by prolyl hydroxylase enzyme which use ascorbate,α ketoglutarate and oxygen
  • α ketoglutarate is oxidatively decarboxylated to form carbon dioxide and succinate
  • Sequence of events leading from a dietary vitamin C deficiency to symptoms such as bruising and breakdown of supporting tissues includes: tissue levels of ascorbic acid is low;  enzyme prolyl hydroxylase is inactive;  proline is not hydroxylated;  the triple helix is inadequately stabilized; collagen breaks down;  defects in tissues that depend on collagen ; tissues that depend on collagen are subject to breakdown and bruising

(b) Sailors are no longer susceptible to scurvy because fresh fruits which are the source of vitamin C source are available now

British sailors called "limeys" to this day,this term reflects the British navy's use of limes
