On the galapagos islands, Darwin studied many creatures, including finches. Explain what he observed and how it relates to natur

Tatiana [17]

Darwin observed the beaks of the birds and how the different beaks helped the birds to eat different types of seeds.

This relates to natural selection because certain finches with say a smaller shorter beak would be able to eat only smaller seeds and fruits as to where a finch with a longer larger beak could eat larger bigger seeds and fruits.

Hope this helped! Have a great day!

A sample of metal has a mass of 24.64 g, and a volume of 5.91 mL. What is the density of this metal?

dlinn [17]

Answer:

$\boxed {\boxed {\sf 4.17 \ g/mL}}$

Explanation:

We are asked to find the density of a metal. Density is the mass per unit volume. It is calculated by dividing the mass by the volume.

$\rho= \frac{m}{v}$

The mass of the metal sample is 24.64 grams and the volume is 5.91 milliliters. We can substitute these values into the formula.

m= 24.64 g
v= 5.91 mL

$\rho=\frac{24.64 \ g }{5.81 \ mL}$

Divide.

$\rho= 4.169204738 \ g/mL$

The mass measurement has 4 significant figures the volume measurement has 3 significant figures. Our answer for density must match the least number of significant figures, which is 3.

For the number we calculated, that is the hundredth place. The 9 in the thousandth place tells us to round the 6 up to a 7.

$\rho \approx 4.17 \ g/mL$

The density of this metal is approximately <u>4.17 grams per milliliter.</u>
