Semester Exam Practice

Front

What is a very small population in an unstable environment likely to experience?

Back

It is most likely to go extinct due to lack of genetic diversity and vulnerability to environmental changes.

Front

What are limiting factors in population growth?

Back

Limiting factors are environmental conditions that restrict population growth, such as food availability, predation, and disease.

Front

What is Active Transport?

Back

Active Transport is the movement of ions or molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy (ATP).

Front

What happens to a cell in a hypertonic solution?

Back

A cell shrinks in a hypertonic solution because water moves out of the cell.

Front

What is the impact of deforestation on local wildlife?

Back

Deforestation leads to habitat destruction, causing many organisms to lose their homes.

Front

What is genetic variability?

Back

Genetic variability refers to the diversity in gene frequencies within a population, which can enhance survival and adaptability.

Front

What is the difference between r strategists and K strategists?

Back

R strategists produce many offspring with low parental care, while K strategists produce fewer offspring with high parental care.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of a cell, leading to water moving out of the cell.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, moving from high to low concentration.

Front

What is the role of ATP in cellular processes?

Back

ATP provides energy for various cellular processes, including active transport and biochemical reactions.
