Photosynthesis & CR
A plant uses this organelle to capture light energy & make glucose?
What is a chloroplast?
The long shape of a nerve cell allows it to send messages throughout the body.
The relationship described above illustrates this important biology concept.
What is structure determines function?
What are alleles?
Individuals with advantageous traits are more likely to do this.
What is survive and reproduce?
This is the role an organism plays in its environment.
What is a niche?
This process releases energy stored in glucose & produces ATP as a result.
What is cellular respiration?
The structure of red blood cells allows them to efficiently perform this function.
What is transporting oxygen?
An organism with two different alleles for a single trait is described as this.
What is heterozygous?
The preserved remains or traces of ancient organisms are called these.
What are fossils?
Plants are classified as this type of organism in a food web/chain/pyramid.
What is an autotroph?
A student places two identical plants in sunlight. One receives water and one does not. After several days, the plant without water begins to wilt.
This is the reason the plant wilts.
What is water is a reactant required for photosynthesis?
A scientist observes a cell with many folded internal membranes called rough ER.
This is the function this cell is likely specialized to perform.
What is protein synthesis/production?
A tall pea plant (Tt) is crossed with a short pea plant (tt).
This is the percentage of offspring that are expected to be short.
What is 50%?
A population of rabbits becomes darker in color after several generations living on dark volcanic rock.
This mechanism best explains the change.
What is natural selection?
A disease drastically reduces the population of wolves in an ecosystem.
This is the immediate effect that would most likely occur in the deer population.
What is the deer population would increase?
A graph shows carbon dioxide levels decreasing in a sealed container containing a healthy plant exposed to light.
This is the reason for the decreasing levels.
What is the biological process of photosynthesis?
A patient has damaged alveoli in their lungs.
This is how the damaged alveoli would impact homeostasis.
What is decreased oxygen uptake and gas exchange?
A family pedigree shows a trait appearing in every generation and affecting both males and females equally.
This inheritance pattern is most likely represented.
What is dominant inheritance?
Scientists compare DNA sequences from two species and find they share 98% of their genes.
The genetic evidence suggests this relationship.
What is the species share a recent common ancestor?
A top predator goes extinct due to the sixth extinction.
This is why many other populations in the ecosystem would be impacted.
What is populations are interconnected and most, if not all, changes cause trophic cascades?
A mutation reduces the number of mitochondria in muscle cells.
This is why the mutation would likely affect the organism's ability to perform physical activity.
What is the organism would produce less ATP through cellular respiration, resulting in reduced energy for muscle contraction?
Two organisms have different heart structures. Organism A has a four-chambered heart, while Organism B has a three-chambered heart.
This is how the structure of Organism A's heart provides an advantage.
What is it keeps oxygen-rich and oxygen-poor blood separated, increasing efficiency of oxygen delivery?
A population of insects shows many different body colors.
This is why genetic variation within a population is important for long-term survival.
What is variation increases the likelihood that some individuals will survive environmental changes and reproduce?
A new predator enters an ecosystem and preferentially eats slower prey individuals.
This is how the prey population may change over many generations (discuss survivability & frequency).
What is faster individuals are more likely to survive and reproduce, increasing the frequency of genes associated with speed?
European starlings are introduced to the USA a second time and compete with native species throughout the country for the same food source.
This is one likely long-term impact on biodiversity with a short explanation.
What is biodiversity may decrease because native species could decline due to competition for limited resources?
