Quarter 3 Review

Genome maps provide the DNA sequences of chromosomes. Some scientists have compared the genome maps of a hedgehog and a sloth. What do these genome maps allow the scientists to determine?

• The color patterns of hybrids between the two species

• The difference in size between individuals of each species

• The method of lipid synthesis that each species uses

• How closely related the two species are to each other

Each organism is part of the ongoing evolution of their species.Genetic variation provides the raw material for different forms of evolution to occur, such as selection and gene flow. Which of the following would have the GREATEST impact on the future of a species?

• advantageous mutations in the gametes

• eproducing through asexual processes

• harmful mutations ocurring in skin cells

• exercising daily to improve an individual's physical fitness

The inverse relationship between jaw size and brain size suggests what about our hominid ancestors?

• a negative effect of bipedalism on hominid ancestors' diet and brain size

• an increase in social interaction between members of hominid populations

• an increase in nutritional value of the foods eaten by hominid ancestors

• an increase in jaw size allowed us to eat more raw meat, causing a decrease in hominid brain size over time

Which of the following does NOT describe a similarity between photosynthesis and cellular respiration?

• Both are necessary for life on Earth.

• 
  Both involve the exchange of gases

• Both transform food into energy.

• Both are transformations of energy.

A major component of the modern study of evolution is the theory of natural selection. Classifying natural selection as a scientific theory means which of the following?

• 
  Natural selection is the only supported explanation of how evolution may occur in a population

• Natural selection is accepted as fact, and scientific understanding of it cannot change based on future investigations.

• Natural selection provides an explanation of how and why evolution occurs that is extremely well supported by evidence.

• Natural selection describes exactly what will occur in a population’s gene pool under certain environmental circumstances.

What is happening to water at D in the figure above?

• Water is falling to the ground as precipitation.

• Water is evaporating from the ocean.

• Water is being taken up by plants through transpiration.

• Water is seeping into the ground to become groundwater.

A cladogram is shown below.

 

 

All of the animals to the right of the salamander would have which common characteristic?

• Fur

• Feather

• Claws or nails

• Mammary glands

An analysis of DNA and RNA sequences can be used to classify organisms. Analysis of these nucleic acids was used to create the model shown below.

 

 

Which statement is supported by the information in this model?

• Lesser pandas are more genetically similar to raccoons than they are to giant pandas.

• Giant pandas are more genetically similar to sun bears than they are to brown bears.

• Brown bears are more genetically similar to giant pandas than they are to sun bears.

• Lesser pandas are more genetically similar to giant pandas than they are to raccoons.

Which of the following trends is consistent with scientists' current understanding of how modern humans differ from early hominid species?

• Modern humans use fewer tools.

• Modern humans have larger jaw bones.

• Modern humans use different cell organelles for protein production.

• Modern humans have larger brain cavities in the skull.

Cellular Respiration is represented by which equation?

• C₆H₁₂O₆ + 6H₂O --> 6O₂ + 6H₂O + Energy

• 12CO₂ + H₂O --> 2C₆H₁₂O₆ + 6O₂

• 6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂

• C₆H₁₂O₆ + 6O₂ --> 6CO₂ + 6H₂O + Energy
