Biology Semester 1 Final

Front

What is Telophase in mitosis?

Back

Telophase is the final stage of mitosis where the nuclear membrane forms around each set of chromosomes, and the cell begins to separate into two daughter cells.

Front

What occurs during Anaphase in mitosis?

Back

During Anaphase, the chromosomes are pulled apart by spindle fibers and move to opposite sides of the cell.

Front

How does deforestation impact biodiversity in a rainforest ecosystem?

Back

Deforestation reduces biodiversity by destroying habitats and food sources for many species.

Front

What is a similarity between tundra and desert ecosystems?

Back

Both tundra and desert ecosystems have low precipitation levels.

Front

What is an example of a density-dependent factor?

Back

Disease is an example of a density-dependent factor that affects population size.

Front

Define biodiversity.

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of species and genetic diversity.

Front

What is the role of the nuclear membrane during cell division?

Back

The nuclear membrane protects the genetic material and helps organize the chromosomes during cell division.

Front

Explain the significance of spindles in mitosis.

Back

Spindles are structures that pull chromosomes apart during mitosis, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What is the difference between density-dependent and density-independent factors?

Back

Density-dependent factors are influenced by population size (e.g., disease, competition), while density-independent factors affect populations regardless of size (e.g., natural disasters).

Front

What is the function of chromosomes?

Back

Chromosomes carry genetic information in the form of genes, which determine the traits of an organism.
