Alleles well-suited to the environment increase the fitness of
organisms, allowing for higher survival and reproduction so that
the beneficial alleles are passed on to future generations and
increase in incidence in the population over time. [ Ans: ] Select
the statement that describes how fitness and natural selection
interact to lead to adaptation.
-As an individual adapts to the environment over its lifetime, it
acquires traits that increase fitness, which are then passed on to its
offspring.
-The traits of a population of organisms change over time, some
making the organisms more suited to the environment and some
making the organisms less suited to the environment.
-Alleles well-suited to the environment increase the fitness of
organisms, allowing for higher survival and reproduction so that
the beneficial alleles are passed on to future generations and
increase in incidence in the population over time.

-All the individuals in a population carry the same alleles such that
the resulting traits are passed on throughout the population over
time but with no change in their occurrence.
-Randomly occurring alleles that give organisms an advantage in
the environment are not passed on to offspring because they are
not heritable traits.
Its fitness would be lower than other strains that lack resistance
because it is spending energy that the resistant strains can use for
other purposes, such as reproduction. [ Ans: ] A bacterial cell
that is resistant to a particular antibiotic may spend a large
amount of energy producing the modified proteins that are
needed for resistance. In such a case, what would be the effect

on this cell's fitness if no antibiotic was present?
-Its fitness would be lower than other strains that lack resistance
Guru01 - Stuvia
because it is spending energy that the resistant strains can use for
other purposes, such as reproduction.
-Its fitness would be the same as other strains that lack resistance
because bacteria have access to so much energy in the
environment that it is not an issue in their fitness.
-Its fitness would be higher than other strains that lack resistance
because it has more available energy to use.
-Its fitness would be higher than other strains that lack resistance
because it is prepared for a future change in the environment.
-Its fitness would be the same as other strains that lack resistance
because no antibiotics affect any of them.

-differences in amount of annual precipitation
-variation in temperature ranges [ Ans: ] The taiga biome is
Guru01 - Stuvia
characterized by evergreen trees, whereas the temperate forest
biome is characterized by evergreens and trees that drop their
leaves during the winter. Which of the following features accounts
for these differences in plant life? Select the TWO answers that are
correct.
-variability in human activities within each
-distinct animal species inhabiting each biome
-differences in amount of annual precipitation
-separation by geographic boundaries
-variation in temperature ranges
Through photosynthesis, land plants remove carbon dioxide from
the atmosphere, thus large-scale removal of trees from the
environment increases the greenhouse effect. [ Ans: ] Human
activities such as deforestation increase the rate of climate
change. Given the basic principles of the carbon cycle, which of
the following is one explanation for why deforestation impacts
global warming?
, 4
For Expert help and assignment solutions, +254707240657
-Removal of trees exposes large areas of land to sunlight, which
results in an overall increase in Earth's surface temperature.
-Through photosynthesis, land plants remove carbon dioxide from
the atmosphere, thus large-scale removal of trees from the
environment increases the greenhouse effect.
-Trees are a fossil fuel like natural gas and coal, thus burning trees
decreases the amount of greenhouse gases released into the
atmosphere.
-Slash-and-burn practices commonly used in deforestation
decrease the amount of carbon dioxide released into the

atmosphere.
-The removal of forests decreases the amount of carbon dioxide
released during cell respiration by these plants, thus reducing the
Guru01 - Stuvia
greenhouse effect.
-Conserve electricity and rely more on power sources with less
carbon impact, such as solar and wind energy.
-Limit the use of gasoline for transportation by using more fuel-
efficient vehicles, carpools, and public transportation. [ Ans: ]
What changes can humans make that can reduce their impact
on the amount of carbon dioxide in the atmosphere? Select the
TWO answers that are correct.
-Increase the use of natural resources such as coal and timber for
industry and economic development.
-Consume only ethically sourced, organic produce, avoiding
pesticides and genetically modified organisms.
-Conserve electricity and rely more on power sources with less
carbon impact, such as solar and wind energy.
-Limit the use of gasoline for transportation by using more fuel-
efficient vehicles, carpools, and public transportation.
