SC.912.L.14.1
Robert Hooke first named cells in 1665 after viewing dead cells of tree bark under a microscope. Inspired by Hooke’s discovery, in 1683 Anton van Leeuwenhoek created his own microscope and viewed living organisms for the first time in pond water. Many scientists after that continued to study and research cells which led to the cell theory. How does the continuous investigation of cells impact our lives today?
Scientists today research cells with the latest technology available. As new technology is developed, new information is learned about the function and structure of the cell. The research helps benefit humans in ways such as; fighting diseases and improving food production.
Scientists today rely on the research of groups of scientists. As new technology is developed, these groups of scientists must come a consensus to determine if they will use it. The research helps benefit humans in ways such as; curing diseases and improving food quality.
Scientists today rely on the research of past scientists to draw conclusions about the cell. As new technology is developed, previous ideas about the function and structure of a cell are confirmed. The research helps benefit humans in ways such as; curing diseases and improving food quality.
Scientists today research cells using the same technology that previous scientist used in order to ensure reliability. As new technology is developed, scientists come to a consensus to determine if they will use it. The research helps benefit humans is ways such as; fighting diseases and improving food production.

Corneal transplants are usually performed using donor tissue. Researchers have discovered a technique that creates corneal tissue from a patient's own limbal stem cells. Which principle of the cell theory supports this research?
Cells come from pre-existing cells.
Cells are created during certain intervals.
Cells that are damaged repair themselves.
Cells are constantly being regenerated through cell division.
SC.912.L.18.9
Scientists have been investigating the change in atmospheric carbon dioxide concentration since about 800 AD. A graph of atmospheric carbon dioxide concentration over time is shown below.
If the trend on the above graph continues, which of the following animals would benefit?
The decrease in atmospheric CO2 would benefit the anaerobic cellular respiration of humans.
The increase in atmospheric CO2 would benefit the aerobic cellular respiration of cows.
The increase in atmospheric CO2 would benefit the photosynthesis of phytoplankton.
The decrease in atmospheric CO2 would benefit the reproduction of grasshoppers.
SC.912.L.18.9
Cellular respiration is important to a person’s body, especially during periods of exercise. When a person exercises, the process of cellular respiration increases the amount of what product in your body?
oxygen and carbon dioxide
oxygen and water
energy in the form of ATP
energy in the form of glucose
SC.912.L.18.9
Earth's atmosphere is about 21 percent oxygen. This percentage has remained about the same throughout human history and even earlier. How have cellular respiration and photosynthesis helped maintain relatively constant oxygen levels?
Cellular respiration helps maintain oxygen levels, while photosynthesis has no effect.
Photosynthesis helps maintain oxygen levels, while cellular respiration has no effect.
Cellular respiration removes oxygen from the atmosphere, while photosynthesis adds oxygen to the atmosphere.
Photosynthesis removes oxygen from the atmosphere, while cellular respiration adds oxygen to the atmosphere.
SC.912.L.16.1
This diagram shows a pedigree for a genetic disorder.
What can be concluded about how this genetic disorder is inherited?
The allele is on the X chromosome
The allele is on the Y chromosome
The genetic disorder is inherited via a sex-linked dominant trait
The genetic disorder is inherited via an incomplete dominance trait
SC.912.L.16.1
In flowers such as pansies assume the alleles for petal colors are as follows: ww= white and rr= red and they are showing incomplete dominance. Which phenotypic ratio would be expected in the offspring of two pink pansies?
1 red : 2 pink : 1 white
0 red : 4 pink : 0 white
3 red : 0 pink : 1 white
4 red : 0 pink : 0 white
SC.912.L.16.1
While working with pea plants, Mendel carefully controlled the transfer of pollen from male to female plants. He found that their seeds could have combinations of green or yellow color with a round or wrinkled texture. Which of Mendel’s laws best explains why genetic variations occur in offspring following sexual reproduction?
Law of crossing over
Law of dominance
Law of segregation
Law of independent assortment
SC.912.L.16.1
A dihybrid cross examines the inheritance of two traits at once. Tall (T) is dominant over short (t) and black (B) is dominant over white (b). Examine the cross between two heterozygous tall and heterozygous black parents. What are the genotypes of the parents?
TtBB x TTBb
TtBB x TtBb
TtBb x TtBB
TtBb x TtBb
SC.912.L.16.1
In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codominant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes?
O only
A or B only
A, B, or O only
A, B, AB, or O
SC.912.L.14.36
Janice is a patient who has been feeling poorly and decides to visit her doctor for a yearly checkup. Her blood work shows elevated cholesterol values. What lifestyle changes can she make to improve her health status?
Cut back on the distance for her daily walks
Reduce her intake of fried foods and processed fatty snacks
Use more animal proteins and dairy products in her recipes
Remove stress by limiting the number of flights of stairs that she climbs at work
SC.912.L.14.36
In a study of physical endurance, researchers observed significant increases in the heart rates and breathing rates of participants immediately after they engaged in strenuous exercise. Which statement best explains the increase in the heart rate and the breathing rate during exercise?
The water concentration in the blood increases
Body cells require increased oxygen as energy is expended
Muscle cells increase in temperature and require fluid to reduce the temperature
An increase in muscle activity causes increases in glucose levels in red blood cells
SC.912.L.16.10
Artificial selection has been employed for thousands of years by animal breeders and plant cultivators. In what way is the genetic engineering of crops similar to the more traditional practice of artificial selection?
Both techniques produce plants with greater resistance to plants
Both methods result in a crop that has some desirable characteristics
In both cases, two different crop plants are crossed to develop a new one
In both procedures, genes from unrelated organisms can be added to the plant
SC.912.L.16.10
Some farmers currently grow genetically engineered crops. What is an argument against the use of this technology?
It increases crop production
It produces insect-resistant plants
It often results in crops that do not taste good
Its long-term effects on humans are still being investigated
SC.912.L.16.10
Bacteria that are removed from the human intestine are genetically engineered to feed on organic pollutants in the environment and convert them into harmless inorganic compounds.
