GAS EXCHANGE AND CELLULAR RESPIRATION
This gas is taken into the lungs and used by cells to release energy from glucose.
What is oxygen?
This process moves water across a cell membrane from high to low concentration.
What is osmosis
This term describes differences among individuals in a population.
What is variation?
This term refers to the community of microorganisms living in the human body.
What is the microbiome?
This enzyme breaks down lactose in milk.
What is lactase?
this process occurs in the mitochondria and releases energy from glucose.
What is cellular respiration?
This organ regulates water balance by filtering blood and producing urine.
What are the kidneys?
These random DNA changes provide the raw material for evolution.
What are mutations?
Most beneficial microbes are found in this part of the digestive system.
What is the large intestine?
Lactose is a type of this macromolecule.
What is a carbohydrate?
These tiny air sacs in the lungs allow oxygen and carbon dioxide to diffuse between air and blood.
What are alveoli?
When a cell is placed in a hypertonic solution, water will move ___ the cell.
What is out of?
These random DNA changes provide the raw material for evolution.
What are mutations?
These microbes help humans digest food and produce certain vitamins.
What are bacteria?
Lactase persistence allows adults to digest milk due to continued enzyme production. This trait is ___.
What is inherited?
This molecule is produced during cellular respiration and is the main energy source for cells.
What is ATP?
Severe dehydration disrupts this biological process by altering enzyme shape and function.
What is homeostasis?
This type of advantage increases an organism’s chances of producing offspring.
What is reproductive advantage?
Antibiotics can disrupt the microbiome by killing harmful and ___ bacteria.
What are beneficial?
In populations with a long history of dairy consumption, lactase persistence became common due to ___.
What is natural selection?
If oxygen delivery to cells decreases, this process becomes less efficient, leading to less ATP production.
What is aerobic respiration?
This hormone helps the kidneys conserve water by increasing water reabsorption.
What is ADH antidiuretic hormone?
Over time, natural selection causes this level of biological organization to change, not individuals.
What is a population?
An imbalanced microbiome can affect digestion, immunity, and this major body function.
What is homeostasis?
Lactase persistence is an example of how culture and this biological process interact.
What is evolution?
