Semester 1 Test Review

Front

What is the genotype of a heterozygous organism?

Back

A heterozygous organism has two different alleles for a trait, represented as Aa.

Front

What does homozygous dominant mean?

Back

Homozygous dominant means having two identical dominant alleles for a trait, represented as AA.

Front

What is the principle of dominance in genetics?

Back

The principle of dominance states that in a heterozygous genotype, the dominant allele will mask the effect of the recessive allele.

Front

What percentage of offspring will have short legs if one parent is heterozygous (Aa) and the other is homozygous dominant (AA)?

Back

100% of the offspring will have short legs.

Front

What is embryonic similarity an indication of in evolutionary biology?

Back

Embryonic similarity suggests that different species may share a common ancestor.

Front

What is a cause-and-effect relationship?

Back

A cause-and-effect relationship indicates that one event (the cause) directly influences another event (the effect).

Front

What happens to the number of washers picked up as more magnets are used?

Back

The more magnets you use, the more washers you can pick up.

Front

How do you calculate net force when two forces act in opposite directions?

Back

Net force is calculated by subtracting the smaller force from the larger force and indicating the direction of the larger force.

Front

If a 4N force acts to the right and a 6N force acts to the left, what is the net force?

Back

The net force is 2N to the left.

Front

What is the role of spring scales in measuring force?

Back

Spring scales measure the force exerted on an object in newtons (N).
