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

What is an example of why the process of photosynthesis is important to life on earth
ruslelena [56]

Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy stored within carbohydrates, like molecules of glucose is produced from light, water and carbon dioxide while oxygen is released.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy

Carbohydrates molecules that supply energy and provide support; they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. Inclusive of monosaccharides, disaccharides and polysaccharides (which describes the type of bonding and the degree of complexity of the polymers), their basic makeup comprises C, H, O -with many polar OH groups.

The energy they store, is required by all living organisms for biological processes; these undergo respiration, in order to release energy stored within its bonds, in the form of the molecule ATP.

WARRIOR [948]

Keratinocytes are differentiated skin cells found in the outermost layer of the epidermis. Dendritic cells are antigen-presenting cells that play important roles in the adaptive immune response.

  • In addition to keratinocytes, the <em>stratum spinosum</em> also contains another epidermal cell type called epidermal DENDRITIC cells that help to fight infection.

  • The s<em>tratum spinosum</em><em> </em>is an epidermal skin layer between the <em>stratum granulosum </em>and<em> stratum basale</em>.

  • Dendritic cells are antigen-presenting cells that are capable of processing harmful antigens in order to present them on the cell surface to the T cells of the immune system.
