Biology 1 Final Exam Review 24-25

Front

What is an abiotic factor in an ecosystem?

Back

An abiotic factor is a non-living component of an ecosystem, such as temperature, water, sunlight, soil, and air.

Front

What is the significance of measuring temperature in a fish bowl ecosystem?

Back

Measuring temperature helps to understand the abiotic conditions that affect the health and behavior of the fish and other organisms in the ecosystem.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.

Front

What is the typical sequence of succession in a pond community?

Back

A typical sequence of succession in a pond community is A-C-B-D, where A represents the initial colonizers and D represents a mature community.

Front

What are codons?

Back

Codons are sequences of three nucleotides in DNA or RNA that correspond to specific amino acids or stop signals during protein synthesis.

Front

How many similarities in codons are observed between gorillas and humans?

Back

3 similarities in codons are observed between gorillas and humans.

Front

What is the relationship between temperature and enzyme function?

Back

Temperature affects enzyme function; typically, enzymes have an optimal temperature range where they function best.

Front

What does Graph A represent in relation to enzyme function and temperature?

Back

Graph A likely shows the optimal temperature range for enzyme activity, indicating increased activity at certain temperatures and decreased activity outside that range.

Front

What is a dominant allele?

Back

A dominant allele is a variant of a gene that will express its trait in the phenotype even if only one copy is present.

Front

According to Mendel, how does a dominant allele affect phenotype?

Back

An organism with a dominant allele (such as TT or Tt) will always show that trait in the phenotype.
