ACP Biology Pre-Exam

Front

What is Facilitated Diffusion?

Back

A type of passive transport that uses protein channels to help move substances across a cell membrane without using energy.

Front

What determines the genetic code of an organism?

Back

The order of the nitrogenous bases in DNA.

Front

What is the genotype of a heterozygous pea plant with round seeds?

Back

Rr (one dominant allele and one recessive allele).

Front

What is NOT a function of proteins?

Back

Short term energy.

Front

What does Homeostasis mean?

Back

Balance in the internal environment of an organism.

Front

What is Passive Transport?

Back

The movement of substances across a cell membrane without the use of energy.

Front

What is the difference between Active and Passive Transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What are nitrogenous bases?

Back

The building blocks of DNA and RNA, consisting of adenine, thymine, cytosine, guanine (and uracil in RNA).

Front

What is a genotype?

Back

The genetic makeup of an organism, represented by alleles.

Front

What is a dominant allele?

Back

An allele that expresses its trait even in the presence of a recessive allele.
