The data below show the favorite pizza toppings for a class.
gayaneshka [121]

When making a circle graph out of these data, the angle that one would use for the wedge that represents pepperoni will be A. 72°

<h3>How to calculate the angle?</h3>

Based on the information given in the question, the following can be deduced:

Cheese 30%

Pepperoni 20%

Onion 15%

Mushroom 20%

Sausage 15%

Total = 100%

From the information, we can see that pepperoni is represented as 20%. It should be noted that in a circle, the angle is 360°.

Therefore, making a circle graph out of these data, the angle that one would use for the wedge that represents pepperoni will be:

= 20/100 × 360°

= 1/5 × 360°

= 72°

Therefore, when making a circle graph out of these data, the angle that one would use for the wedge that represents pepperoni will be A. 72

The biochemical and physiological process by which an organism uses food to sustain its life is known as nutrition. Consumption, absorption, assimilation, biosynthesis, catabolism, and excretion are all included. Nutritional science is the field of study that focuses on the physiological aspects of nutrition.

Pest control agents are compounds known as pesticides. Insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insecticide, animalized, microbicide, fungicide, and lampricide are some examples of these.

  • <em>The linkage between the sister chromatids </em>is particularly critical at centromeres because it ensures right <em>microtubule connection to the kinetochores </em>
  • In eukaryotes, a centromere is a district of DNA that is responsible for the development of the imitated chromosomes into the<em> two daughter cells during mitosis and meiosis</em>
  • There is one centromere on every <em>chromosome and centromeres are responsible for two major functions</em>
  • In eukaryotes, a centromere is a district of DNA that is responsible for the development of the imitated chromosomes into the  <em>two daughter cells  during mitosis and meiosis</em>
