Scientists are unable to research the organs, tissues, and cells of early organisms as these parts are rarely fossilized. Which is one reason for the lack of these fossilized parts?

A. These parts quickly decompose.

Explanation: This is because organs are made of tissues that decompose more quickly than bone. Animals mainly eat the organs and tissues of another, not the bones. This results in quick destruction of these parts that are left behind.

A

Explanation:

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

the answer is d.) potassium
