Biology EOC Review

Front

What are the three parts that make up a nucleotide?

Back

A nucleotide is made up of a sugar, a phosphate, and a base.

Front

How does natural selection improve a population?

Back

Natural selection improves a population by allowing the individual organisms that are best adapted to the current environment to survive, increasing their gene types in the population.

Front

How can cells from the same organism have different shapes and functions?

Back

Cells from the same organism can have different shapes and functions because during differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.

Front

What does tRNA deliver to the ribosomes during translation?

Back

tRNA delivers amino acids to the ribosomes during translation.

Front

What elements make up carbohydrates?

Back

Carbohydrates are made up of carbon (C), hydrogen (H), and oxygen (O).

Front

What is the role of DNA in cell differentiation?

Back

DNA plays a crucial role in cell differentiation by determining which genes are activated in each type of cell, leading to specialized functions.

Front

Define natural selection.

Back

Natural selection is the process by which organisms that are better adapted to their environment tend to survive and produce more offspring.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA (mRNA) into amino acid sequences.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

Explain the process of transcription.

Back

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
