2.

Separation of populations of a species for long times into different areas

Extinction
Background extinction
Geographic isolation
Specialist species
Biological evolution

Correct Answer

A. Geographic isolation

Explanation

Geographic isolation refers to the physical separation of populations of a species into different areas for an extended period of time. This isolation prevents gene flow between the populations, leading to genetic divergence and the formation of new species over time. This process is a crucial mechanism in biological evolution as it allows for the accumulation of genetic differences and the development of unique adaptations in isolated populations. Therefore, geographic isolation is the most appropriate explanation for the given statement.

Process by which a particular beneficial gene (or set of genes) is reproduced in succeeding generations more than other genes; the result of natural selection is a population that contains a greater proportion of organisms better adapted to certain environmental.

Natural selection
Ecological niche
Realized niche
Mass extinction
Artificial selection

Correct Answer

A. Natural selection

Explanation

Natural selection is the process by which certain beneficial genes or sets of genes are passed on to future generations more frequently than other genes. Over time, this leads to a population that contains a higher proportion of organisms that are better adapted to their environment. This process is driven by the environment and the survival and reproductive success of individuals with advantageous traits. It is a key mechanism of evolution and explains how species become better suited to their ecological niches over time.

Total way of life or role of a species in an ecosystem; it includes all physical, chemical an biological conditions that a species needs to live and reproduce in an ecosystem

Fundamental niche
Ecological niche
Realized niche
Generalists species
Specialist species

Correct Answer

A. Ecological niche

Explanation

The ecological niche refers to the total way of life or role of a species in an ecosystem. It encompasses all the physical, chemical, and biological conditions that a species requires to survive and reproduce in a particular ecosystem. This includes factors such as the species' habitat, its interactions with other species, its feeding habits, and its reproductive strategies. The ecological niche determines the species' position and function within the ecosystem, and it is essential for understanding the species' ecological requirements and its impact on the ecosystem.

Species with a broad ecological niche. They can live in many different places, eat variety of foods, and tolerate a wide range of environmental conditions

Specialist species
GMO's
Speication
Endemic species
Generalists species

Correct Answer

A. Generalists species

Explanation

Generalist species are able to adapt and thrive in a wide range of environments, consume a variety of foods, and tolerate different environmental conditions. They have a broad ecological niche, which allows them to occupy many different habitats and exploit various resources. This adaptability and flexibility make generalist species more resilient to changes in their environment compared to specialist species, which have specific requirements and are limited to certain habitats or food sources. Therefore, the given answer, generalist species, is the most suitable choice based on the provided information.

Random structure or number of DNA molecules in a cell that can be inherited by offspring

Biological evolution
Differential reproduction
Adaptation
Mutations
Natural selection

Correct Answer

A. Mutations

Explanation

Mutations refer to changes in the DNA sequence, which can occur randomly or due to external factors such as radiation or chemicals. These changes can be inherited by offspring and play a crucial role in biological evolution. Mutations introduce genetic variation, which is essential for adaptation and natural selection to occur. They can lead to new traits or characteristics, and individuals with beneficial mutations are more likely to survive and reproduce, passing on these advantageous traits to future generations. Therefore, mutations are a fundamental mechanism driving evolution and the diversity of life on Earth.

Widespread, often global period during which extinction rates are higher than normal but not high enough to classify as a mass extinction

Mass extinction
Geographic isolation
Artificial selection
Endemic species
Mass depletion

Correct Answer

A. Mass depletion

Explanation

Mass depletion refers to a widespread period during which extinction rates are higher than normal but not high enough to classify as a mass extinction. This means that a significant number of species are being lost, but it does not reach the level of a mass extinction event where a large proportion of species are wiped out. The term "mass depletion" implies a gradual decline in species rather than a sudden and catastrophic event.

8.

formation of two species from one species because of divergent natural selection in response to changes in environmental conditions

Speciation
Generalists species
Endemic species
Specialists species
GMO's

Correct Answer

A. Speciation

Explanation

Speciation refers to the formation of two different species from one species. This occurs due to divergent natural selection, where different populations of the same species adapt to different environmental conditions. As the environmental conditions change, the populations become genetically distinct and can no longer interbreed, leading to the formation of two separate species. Therefore, speciation is the correct answer as it best explains the process of two species forming from one due to divergent natural selection in response to changes in environmental conditions.

9.

Normal extinction of various species as a result of changes in local environmental conditions.

Mass extinction
Background extinction
Mass depletion
Extinction
Geographic isolation

Correct Answer

A. Background extinction

Explanation

Background extinction refers to the normal, ongoing process of species becoming extinct over time due to changes in their local environmental conditions. This is in contrast to mass extinctions, which are catastrophic events that result in the widespread extinction of many species. The given answer correctly identifies the concept of background extinction as the explanation for the normal extinction of various species.

10.

Organism whose genetic makeup has been altered by genetic engineering.

Correct Answer
GMOs

Explanation
GMOs, or genetically modified organisms, refer to organisms that have had their genetic makeup altered through genetic engineering. This can involve the insertion of genes from another organism to enhance certain traits or characteristics. GMOs are created to improve crop yield, increase resistance to pests or diseases, or enhance nutritional value. They have been widely used in agriculture and food production. The term "GMOs" is commonly used to describe these genetically modified organisms.
