Answer:

3.45g/cm³

Explanation:

The density of a substance/object can be calculated by using the formula:

Density = mass/volume

Where;

Density = g/cm³

Mass = grams

Volume = cm³

According to this question, a student measured the mass and volume of an object using a triple beam balance and a graduated cylinder. The sample has a mass of 22.4 grams and a volume of 6.5cm³.

Hence, the density of the object can be calculated this;

Density = mass/volume

Density = 22.4/6.5

Density = 3.4461

To the nearest hundredth, the density of the object = 3.45g/cm³

f- can roll tongue,  long arms

g- brown eyes, brown hair

h- widows peak, short arms

i- brown eyes, can roll tongue

j- brown eyes, brown hair, no widows peak, long arms, can't roll tongue

Explanation:

So the capital letter is the dominant trait, and the lowercase letter is recessive. The capital dominant trait will always overpower the lowercase recessive trait. So the only way the recessive trait can be seen is if there are two together. So... if R is white fur and r is brown fur...

RR would show the dominant trait of white fur

Rr would show the dominant trait of white fur

rr would show the recessive trait of brown fur
