What is crossing over in genetics?

Back

Crossing over is the process during meiosis where homologous chromosomes exchange segments of genetic material, leading to genetic variation in the offspring.

What are the two main types of rocks?

Back

The two main types of rocks are sedimentary rocks, which are formed from the accumulation of sediment, and metamorphic rocks, which are formed from the alteration of existing rocks due to heat and pressure.

How does rainfall affect mosquito populations?

Back

Mosquitoes require standing water to lay their eggs. Less rainfall leads to fewer standing water sources, which can decrease the mosquito population.

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

What happens to fish populations when predators are removed from an ecosystem?

Back

When predators like sharks are removed, the population of their prey, such as small fish, is likely to increase due to reduced predation.

Front

Define non-disjunction in genetics.

Back

Non-disjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division, leading to gametes with an abnormal number of chromosomes.

Front

What is the difference between limestone and marble?

Back

Limestone is a sedimentary rock formed from calcium carbonate, while marble is a metamorphic rock formed from the recrystallization of limestone under heat and pressure.

Front

What is the significance of genetic variation?

Back

Genetic variation is important for the survival of a species as it allows populations to adapt to changing environments and resist diseases.

Explain the concept of an ecosystem.

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic (living) and abiotic (non-living) components.

Front

What is the role of a predator in an ecosystem?

Back

Predators help maintain the balance of ecosystems by controlling the population of prey species, which can prevent overpopulation and depletion of resources.
