Chloroplasts are visible inside the cells.
Digestive organs are visible upon dissection.
The organism lives close to the surface.
The organism synthesizes enzymes to digest food.
Light and biodiversity
Temperature and amount of available water
Types of producers and decomposers
PH and number of heterotrophs
Producers are not as important as consumers in a food web
More consumers than producers are needed to support the food web
Organisms in this food web are interdependent
Populations tend to stay constant in a food web
The population would be more likely to adapt to a changing environment.
There would be little chance for variation within the population.
The population would evolve rapidly.
The mutation rate in the population would be rapid.
Wing shape is controlled by behavior
Wing shape is influenced by light intensity
Gene expression can be modified by interactions with the environment
Gene mutations for wing shape can occur at high temperatures
Twenty kinds of amino acids in each protein
Twenty-three pairs of genes on each chromosome
Strands of simple sugars in certain carbohydrate molecules
Four types of molecular bases in the genes
Organs → organism → cells → tissues
Organism → cells → organs → tissues
Cells → tissues → organs → organism
Organism → organs → tissues → cells
Bacterial cells will destroy defective human genetic material.
Bacterial cells may form a multicellular embryo.
The inserted human DNA will change harmful bacteria to harmless ones.
The inserted human DNA may direct the synthesis of human proteins.
Decreases the chance for new combinations of inheritable traits in a species
Decreases the probability that genes can be passed on to other body cells
Increases the chance for variations in offspring
Increases the number of offspring an organism can produce
May result in the production of a defective protein
May alter the sequence of simple sugars in insulin molecules
Can lead to a lower mutation rate in the offspring of the human
Can alter the rate of all the metabolic processes in the human
Can be used for photosynthesis
Is too large to pass through cell membranes
Is needed for cellular respiration
Can be used for the synthesis of proteins
Methods of reproduction
Number of their ATP molecules
Sequences in their DNA molecules
Structure of protein molecules present
More of the turtles’ ancestors who acted in this way survived to reproduce, passing this behavioral trait to their offspring.
The baby turtles are genetically identical, so they behave the same way.
Turtles are not capable of evolving, so they repeat the same behaviors generation after generation.
The baby turtles’ ancestors who learned to behave this way taught the behaviors to their offspring
All genetic material comes from one parent.
Only some of the genetic material comes from one parent.
The size of the parent determines the amount of genetic material.
The size of the parent determines the source of the genetic material.

An allergic reaction
An antigen-antibody reaction
Maintenance of homeostasis
Human actions are a threat to equilibrium in ecosystems.
Equilibrium in ecosystems requires that humans modify ecosystems.
Equilibrium in ecosystems directly affects how humans modify ecosystems.
Human population growth is the primary reason for equilibrium in ecosystems.
Decomposers are being destroyed
Deforestation has increased the levels of oxygen in the atmosphere
Industrialization has increased the amount of carbon dioxide in the air
Growing crops is depleting the ozone shield
Environmental carrying capacity
Excessive dissolved oxygen
The depth of water
The ecosystem will change until a new stable community is established.
Succession will continue in the ecosystem until one species of marine organism is established.
Ecological succession will no longer occur in this marine ecosystem.
The organisms in the ecosystem will become extinct.
Increasing the diversity of life
Recycling of nutrients
The control of pathogens
The production of new species
The improved quality of the atmosphere
The maintenance of dynamic equilibrium
An increase in the rate of evolutionary change
The loss of biodiversity
Oxygen production decreases as the wavelength of light increases from 550 to 650 nm.
Respiration rate in the bacteria is greatest at 550 nm.
Photosynthetic rate in the algae is greatest in blue light.
The algae absorb the greatest amount of oxygen in red light.

The level of progesterone would start to increase.
The pituitary would produce another hormone to replace hormone 3.
Gland A would begin to interact with hormone 3 to maintain homeostasis.
The level of testosterone may start to decrease.
Every activity in gland A is different from the activities in glands B and C.
The cells of glands B and C contain different receptors than the cells of gland A.
Each gland contains cells that have different base sequences in their DNA.
The distance a chemical can travel is influenced by both pH and temperature.
