Biology Milestone Review #2

Front

What is a frameshift mutation?

Back

A frameshift mutation is a genetic mutation caused by insertions or deletions of nucleotides in a DNA sequence that shifts the reading frame of the genetic code.

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide in a DNA sequence, which can result in a different amino acid being incorporated into a protein.

Front

What is the role of the Golgi apparatus in a cell?

Back

The Golgi apparatus sorts, modifies, and packages proteins and lipids for secretion or delivery to other organelles.

Front

How does deforestation affect carbon dioxide levels?

Back

Deforestation increases carbon dioxide levels in the atmosphere due to decreased photosynthesis, as fewer trees are available to absorb CO2.

Front

What is mutualism?

Back

Mutualism is a type of symbiotic relationship where both species benefit from the interaction, such as the wrasse and moray eel.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is respiration in biological terms?

Back

Respiration is the process by which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What is the function of ribosomes?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA (mRNA) into amino acid sequences.

Front

What is the significance of genetic mutations?

Back

Genetic mutations can lead to variations in traits, which can affect an organism's survival and reproduction, contributing to evolution.

Front

What is the difference between commensalism and parasitism?

Back

In commensalism, one organism benefits while the other is neither helped nor harmed; in parasitism, one organism benefits at the expense of the other.
