Heredity
A species of genetically similar rabbits are raised in different environments that have different temperature conditions. Although these rabbits are genetically the same, they exhibit different fur colors. What is the best reasoning for this occurrence?
Environmental factors are determining how the rabbits' genotype is expressed
Mutations have altered the rabbits genotypes in the differing environments
Cross-breeding with different species has created rabbits of different appearances
The genotype adapts to the different environments and that change is then expressed through the phenotype
How might a plant in an environment with variable sunlight demonstrate phenotypic plasticity?
The plant maintains the same leaf size regardless of sunlight exposure.
The plant exhibits a genetic mutation leading to variegated leaf color.
The plant produces flowers only during short-day conditions.
The plant develops larger leaves in low-light conditions.
In an anaerobic environment, how might a yeast cell produce ATP?
Employing chemosynthesis by oxidizing inorganic substances for energy production without oxygen.
Through photophosphorylation utilizing light energy to generate ATP without oxygen.
By undergoing fermentation to convert glucose into ethanol and carbon dioxide.
By utilizing oxygen to efficiently convert glucose into ATP via aerobic respiration.
In a model of forest ecosystem recovery post-wildfire, which process would most directly facilitate the return to pre-disturbance levels of biodiversity in the long term?
Short-term dominance by fast-growing grass species.
Temporary rise in populations of herbivorous animals.
The reestablishment of pioneer species that enrich soil nutrients.
Increased sunlight penetration immediately following tree loss.
Sex determination in reptilians are dependent on which of the following?
Genetic makeup
Population
Predators
Temperature
Which scenario best describes how temperature changes can act as a selective pressure on enzyme activity within a species' population?
Enzyme activity levels remain constant across populations despite temperature fluctuations since they are highly conserved proteins.
All members of a species experience spontaneous mutations granting them thermostable enzymes when exposed temporarily to higher temperatures.
Populations living in hotter climates have enzymes that function optimally at higher temperatures, reflecting genetic adaptation over generations.
Individuals within cooler climates evolve heat-resistant enzymes despite no direct advantage or selective pressure being present.
How can climate change put reptilians in danger of decrease?
As temperatures get warmer, more females will be born and male birth rates will decrease
As temperatures get lower, more females will be born and male birth rates will decrease
As temperatures get warmer, more males will be born and female birth rates will decrease
As temperatures get warmer, more males will be born and female birth rates will decrease
