Mid-Year Final Practice

Front

What determines inherited traits such as ear shape in puppies?

Back

Inherited traits are determined by DNA in genes located in the nuclei of their cells.

Front

Which rock layer is typically formed first in geological formations?

Back

Rock Layer Z is usually the first layer formed.

Front

What can be inferred about genetic inheritance if a child resembles one parent more than the other?

Back

A scientist would infer that the child received exactly 23 chromosomes from each parent, regardless of resemblance.

Front

Which two systems work together to transport white blood cells to infection sites?

Back

The immune system and the circulatory system work together for this purpose.

Front

What is selective breeding?

Back

Selective breeding is the process performed by humans to achieve desired traits in organisms.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring without human involvement.

Front

How many chromosomes do humans inherit from each parent?

Back

Humans inherit 23 chromosomes from each parent, totaling 46.

Front

What role do white blood cells play in the body?

Back

White blood cells help fight off pathogens and protect the body from infections.

Front

What is the difference between selective breeding and natural selection?

Back

Selective breeding is human-directed, while natural selection occurs naturally without human intervention.

Front

What is the function of DNA?

Back

DNA carries genetic information that determines the traits of an organism.
