Human Body and Genetics - Demo

The following is a sampling of questions from our Human Body and Genetics testbank.

Erythroblastosis fetalis is a blood disorder that may attack babies inside the mother's uterus. The disorder is caused by
  1. the rhesus factor
  2. blood type A groupings
  3. malfunctioning leukocytes
  4. too many type B blood cells
Killer T cells are released into the bloodstream to
  1. locate diseased cells and puncture holes in the membranes of the cells
  2. couple with the macrophage cells and produce lymphokine to mark the diseased cells
  3. suppress the work of the leukocytes indicating that the disease has been eradicated
  4. engulf diseased cells to stop them from spreading

  1. frontal lobe
  2. parietal lobe
  3. occipital lobe
  4. temporal lobe
Humans can feel pain, pressure, touch, and texture. They become aware of these sensations through stimulation of the

Use the following information to answer questions # 72 - 73.

The increased sugar levels cause
  1. the pancreas to release glucagon
  2. the liver to convert glycogen
  3. a negative feedback to occur
  4. insulin to be released
At step C the reaction of the liver will be to
  1. release insulin into the bloodstream
  2. remove excess glucose by releasing glucagon
  3. negate the effects of eating the high sugar meal
  4. cause body cells to become impermeable to glucose

The passage of eggs down the oviduct may become hampered or impossible due to the malady of a sexually transmitted disease. Some STD's if left untreated cause massive scarring within the fallopian tubes. The tubes end up completely blocked. Which STD can cause blocked fallopian tubes?
  1. gonorrhoea
  2. syphilis
  3. herpes
  4. AIDS

Use the following diagram to answer questions # 37 - 41.

The diagram represents the
  1. ovary
  2. follicle
  3. testicle
  4. prostate gland
Which letter represents the corpus luteum?
  1. A
  2. B
  3. C
  4. E
Implantation of the fertilized egg takes place during the cleavage phase called
  1. blastocyst
  2. gastrula
  3. morula
  4. zygote
The release of relaxin, the increase of oxytocin levels, and the decrease of estrogen and progesterone levels denote the advancing stage of
  1. implantation
  2. child birth
  3. ovulation
  4. lactation

Use the following diagram to answer questions # 6 - 7.

When chromosomes line up in this fashion inside the cell we say the cell is undergoing the stage of
  1. prophase I in meiosis
  2. anaphase I in meiosis
  3. prophase in mitosis
  4. anaphase in mitosis
The pairing of similar chromosomes is called
  1. crossing over
  2. chromatids
  3. chiasmata
  4. synapsis

Use the following information to answer questions # 70 - 71.

The genotype of the black, long haired female guinea pig is
  1. BBSs
  2. BbSs
  3. bbss
  4. Bbss
In order to study the effects of alleles within the human population, a researcher would require which statement as a step in the research?
  1. reading about the various types of nucleotides
  2. separating the living from the dead organisms
  3. collecting personal data from human sources
  4. taking the temperature of the test subjects
A scientist tried unsuccessfully to breed the pink colour out of a strain of snapdragons she was working with. Each time one of her white and red plants cross-pollinated she would receive pink flowers. What was the problem he was facing?
  1. Snapdragons are an inferior type of plant to selective breed.
  2. Colour in snapdragons is due to intermediate inheritance.
  3. Pink colouration is a result of codominance.
  4. The snapdragons are pink dominant plants.
In Labrador retrievers black coat colour is dominant to yellow coat colour and large paws are dominant to small paws. Which ratio of crosses would not be possible for producing black, large pawed pups if a large pawed, black Labrador was mated with a large pawed, yellow Labrador?
  1. 25%
  2. 37.5%
  3. 50%
  4. 100%
An E. coli bacterium that has a section of DNA from a human pancreas cell spliced into its sequence will
  1. produce insulin along with its own proteins
  2. die due to the change in its DNA structure
  3. continue its own natural functions
  4. produce only insulin
