What is "the different environments influenced the expression of its genes"?
What is the goal of homeostasis?
What is "maintain your body's internal condition while external conditions change"?
What can be used to predict the outcomes of traits for an offspring?
What is "a punnett square"?
What is natural selection?
What is "determines the desired traits to increase the chance of survival within an ecosystem"?
What is the name of the nitrogen base pairs for DNA?
What is "adenine, thymine, guanine and cytosine"?
What is "ribosomes"?
What is the significance of three consecutive nucleotides in DNA?
What is "codes for one amino acid"?
Victor has a 20yr. old sister. Her height is 5"4. Which statement best explains why his sister is shorter than him and their parents?
What is "his sister received the recessive alleles from their parents"?
How might mutations contribute to natural selection?
What is "adds variation to the gene pool of a population"?
What natural elements are found in DNA?
What is "carbon, hydrogen, oxygen, nitrogen and phosphorus"?
How does the cellular membrane contribute to homeostasis within the cell?
What is "it is a selectively permeable membrane that allows materials to move in and out the cell as needed"?
What occurs when an enzyme is exposed to an increase of heat?
What is "the enzyme will become denatured and no longer work"?
The black rat is responsible for causing the bubonic plague in the 1300s. Over time, survivors showed an increased frequency of a mutation that prevented further infection. What would be the genetic change in the population after the bubonic plague outbreak?
What is "people began to adapt to be resistant of the bacteria from the plague"?
How could a scientist best determine whether a fungus is a new species?
What is "comparing the DNA sequence of the fungus to other known fungi?"
What is the sugar that is used for DNA?
What is "deoxyribose"?
Why are the cells of an embryo considered diploid?
What is "because of fertilization"?
What occurs during protein synthesis?
What is "mRNA attaches to tRNA to create specific amino acids"?
What is the correct transfer of energy in a stable ecosystem?
What is "producer > primary consumer > secondary consumer > tertiary consumer"?
A population of rabbits lives in a forest. Some of the rabbits have a mutation that results in extra-powerful hind legs. What will most likely happen to the population of rabbits if a population of wolves is introduced to the forest?
What is "the number of rabbits with powerful legs will increase over time because they can better escape the wolves"?
What is needed to construct a DNA molecule?
What is "sugar, phosphate group and nitrogen bases"?
How does photosynthesis and cellular respiration differ from one another in terms of energy?
What is "photosynthesis stores solar energy and cellular respiration releases energy"?
After swimming, your body develops wrinkles all over your hands and feet. What best explains why this occurred?
What is "the water in the pool is hypertonic"?
How would a longer snow season affect the populations of red and white foxes living in the same ecosystem?
What is "white foxes would have a greater advantage, so their population size would increase, while the red fox population size would decrease"?
