The organisms that live on Earth today have reached their current forms by inheriting traits that allowed their ancestors to survive and reproduce.

Explanation:

A scientific statement is similar to a thesis, that is able to be investigated and tested to be proven true or false in repeatable experiments.

The organisms that live on Earth today have reached their current forms by inheriting traits that allowed their ancestors to survive and reproduce.

The data from tens of thousands of controlled scientific investigations show that Earth's average surface temperatures are increasing.

Explanation:

The both statements above are scientific. The first statement refers to the process of natural selection and evolution. Species on earth today inherited certain traits from their ancestors that enabled them to be better adapted to their environment and survive.

Data from several scientific investigations is used to establish facts in science. In this case, to establishing the rising surface temperature of the earth.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
