Structure and Function
This is the molecule in cells that stores genetic information and codes for proteins.
What is DNA?
If two carriers of cystic fibrosis (Ff) have a child, this is the chance the child will have the disorder.
What is 25%?
This geographic feature separates northern and southern green anole populations, reducing gene flow.
What is a mountain range?
This trend in summer temperatures contributed to the 2025 Los Angeles wildfires.
What is increasing average summer temperatures?
This is the process of cell division that ensures each new cell receives an identical set of chromosomes.
What is mitosis?
A mutation in a gene can lead to this, allowing cells to grow and divide uncontrollably.
What is cancer?
This percentage of offspring are likely to be carriers if both parents are Ff.
What is 50%?
Longer legs in lizards may evolve due to this selective pressure related to their environment.
What is increased distance between trees?
The main cause of modern global climate change.
What are human activities, particularly burning fossil fuels?
A change in the DNA sequence, such as an insertion, deletion, or substitution, is called this.
What is a mutation?
This term describes how cancer cells bypass normal cell cycle checkpoints, overwhelming the body's regulatory systems.
What is a disruption of homeostasis?
If one parent is Ff and the other is FF, this is the chance their child will inherit cystic fibrosis.
What is 0%?
Lizards in colder northern climates may evolve thicker scales for this reason.
What is better insulation?
Daily weather data contributes to this long-term atmospheric pattern.
What is climate?
A mutation that adds an extra base into the DNA sequence is called this.
What is an insertion?
This system is directly affected when lung tumors disrupt oxygen exchange.
What is the respiratory system?
This is the inheritance pattern of cystic fibrosis.
What is autosomal recessive?
According to climate models, southern lizards are more affected by heat due to this factor.
What is lower altitude and higher temperature?
These gases trap heat in the Earth's atmosphere, causing global warming.
What are greenhouse gases?
When mutations affect this type of gene, they can lead to uncontrolled cell division and possibly cancer.
What are regulatory genes or tumor suppressor genes?
An experiment comparing mitosis in healthy and cancerous cells would help you study the failure of these mechanisms.
What are feedback mechanisms?
This term describes the central dogma of molecular biology.
What is DNA → RNA → Protein?
Group behavior, like social hierarchies, influences these evolutionary advantages.
What are access to resources and mating opportunities?
One city policy that promotes sustainable urban development and reduces CO2 emissions.
What is expanding public transportation and incentivizing electric vehicles?
During normal cell division, these checkpoints monitor the process and prevent damaged cells from dividing.
What are cell cycle checkpoints?
