Biology EOC Review 25

Front

What is differentiation?

Back

Differentiation is the process by which a less specialized cell becomes a more specialized cell type, allowing for the development of different cell types from the same fertilized egg.

Front

What is the optimal temperature and pH for enzyme activity based on reaction rate graphs?

Back

The optimal temperature is 37°C and the optimal pH is 6.

Front

Which reproductive process produces the most variation within a species?

Back

Sexual reproduction produces the most variation within a species due to the combination of genetic material from two parents.

Front

What does an energy pyramid illustrate?

Back

An energy pyramid illustrates the flow of energy through different trophic levels in an ecosystem, showing how energy decreases as it moves from producers to primary consumers to secondary consumers.

Front

Why is it important to report a sea turtle stranding?

Back

Reporting a sea turtle stranding is important because the information can help biologists and managers protect the species and understand the health of the population.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

Define sexual reproduction.

Back

Sexual reproduction is a biological process where two parents contribute genetic material to produce offspring, resulting in genetic diversity.

Front

What is the significance of the secondary consumer level in an energy pyramid?

Back

The secondary consumer level represents organisms that eat primary consumers, and they receive only a fraction of the energy available at the primary consumer level.

Front

What is the difference between asexual and sexual reproduction?

Back

Asexual reproduction involves a single organism producing offspring identical to itself, while sexual reproduction involves two organisms combining genetic material.

Front

What factors can affect enzyme activity?

Back

Enzyme activity can be affected by temperature, pH, substrate concentration, and the presence of inhibitors or activators.
