Question 1

Total fertility rate refers to________.

Accepted Answer

Total fertility rate is the average number of children that would be born to a woman over her lifetime if she were to experience the exact current age-specific fertility rates through her lifetime and she were to survive from birth through the end of her reproductive life.

Question 2

The lowest fertility rates may be found in________.

Accepted Answer

C

Question 3

Assuming no migration, birth rate minus death rate is equal to ________.

Accepted Answer

The difference between the birth rate and the death rate, assuming no migration, determines whether a population is increasing or decreasing.

Question 4

An organism's ________for many environmental factors determines where it can live.

Accepted Answer

An organism's range of tolerance for environmental factors determines the conditions under which it can survive and thrive, thus influencing where it can live.

Question 5

An organism's range of tolerance is most closely related to an organism's________ 	.

Accepted Answer

An organism's range of tolerance refers to the range of environmental conditions (such as temperature, humidity, pH, etc.) that it can endure before injury or death. This is closely related to its ecological niche, which includes the range of conditions and resources within which the organism can survive and reproduce.

Question 6

What was one of the main causes of the Galapagos Island finches' death in 1977?

Accepted Answer

In 1977, a severe drought hit the Galapagos Islands, leading to a scarcity of food resources, which caused a significant number of finches to die due to starvation.

Question 7

What are the three requirements for photosynthesis?

Accepted Answer

Photosynthesis requires sunlight, carbon dioxide, and water to produce glucose and oxygen.

Question 8

From what process do all organisms use energy to power their physical, behavioral, and reproductive functions?

Accepted Answer

Cellular respiration is the process by which organisms convert biochemical energy from nutrients into ATP, which is used to power various functions.

Question 9

In asexual reproduction,________.

Accepted Answer

The answer of In asexual reproduction,________.	  
...

Question 10

Population growth is determined by________.

Accepted Answer

Population growth is determined by birth, death, and net migration, as these factors directly affect the number of individuals in a population. Net migration accounts for both immigration and emigration.

Question 11

In the process of natural selection, the organisms most likely to survive are________

Accepted Answer

Natural selection favors organisms that are most reproductively fit, meaning they have traits that enhance their ability to survive and reproduce in their environment.

Question 12

The medium ground finches (normally distinguished by a range of beak sizes) that survive drought conditions in the Galapagos are able to eat the large and tough seeds from the fever plant. This survival can be described best as 	_______.

Accepted Answer

Directional selection occurs when environmental pressures favor one extreme phenotype over others, leading to a shift in the population's traits, such as larger beak sizes in finches that can eat tough seeds.

Question 13

If a tiger and a lion were to mate, what may be a result?

Accepted Answer

When a tiger and a lion mate, they can produce hybrids such as ligers or tigons, which are typically sterile or have reduced fertility, especially in males.

Question 14

The mating ritual of the blue- footed boobies in the Galapagos Islands includes a complex dance. The birds will not mate with other birds that do not know the dance. This is an example of________ .

Accepted Answer

The answer of The mating ritual of the blue- footed...

Question 15

Different insect species may not pollinate a plant because of the shape or color of its flowers. This is best described as________.

Accepted Answer

Structural isolation occurs when physical differences between species prevent successful mating or pollination, such as the shape or color of flowers affecting which insects can pollinate them.

Question 16

A kingdom in the hierarchical system of classification can be defined as________.

Accepted Answer

A kingdom is one of the highest taxonomic ranks, grouping together all forms of life having certain fundamental structural and functional similarities.

Question 17

In the hierarchical system of classification, a family can be defined as________.

Accepted Answer

A family is a major subdivision of an order and contains one or more genera.

Question 18

In the hierarchical system of classification, species are defined as________.

Accepted Answer

Species are defined as a group of individuals that can interbreed and produce fertile offspring, which is the most specific level of classification in the biological hierarchy.

Question 19

The scientific, two- part Latin name of a species ________.

Accepted Answer

The scientific name of a species, also known as the binomial nomenclature, is composed of two parts: the genus name and the species name.

Question 20

Genetic drift refers to________.

Accepted Answer

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles (inherited traits) in a population, often due to chance events, rather than natural selection.
