Human Body and Genetics - Demo
The following is a sampling of questions from our Human Body and Genetics testbank.
A student observing a microscope slide of a blood smear would find in greatest abundance
Erythroblastosis fetalis is a blood disorder that may attack babies inside the mother's uterus. The disorder is caused by
- helper T cells
Killer T cells are released into the bloodstream to
- the rhesus factor
- blood type A groupings
- malfunctioning leukocytes
- too many type B blood cells
Birds and bees see objects through infrared sensations, dogs visualize objects in shades of gray, and humans are capable of seeing objects in 3 - dimensions and colour. The region of the brain that is stimulated in each of these organisms is the
- locate diseased cells and puncture holes in the membranes of the cells
- couple with the macrophage cells and produce lymphokine to mark the diseased cells
- suppress the work of the leukocytes indicating that the disease has been eradicated
- engulf diseased cells to stop them from spreading
Humans can feel pain, pressure, touch, and texture. They become aware of these sensations through stimulation of the
- frontal lobe
- parietal lobe
- occipital lobe
- temporal lobe
- sensory neurons
- motor neurons
- vagus neurons
Use the following diagram to answer questions # 21 - 24.
The structure responsible for regenerating a damaged interneuron is labelled
Interneuron transmission occurs from
- A to B
- C to D
- D to B
- D to C
Use the following information to answer questions # 72 - 73.
The increased sugar levels cause
At step C the reaction of the liver will be to
- the pancreas to release glucagon
- the liver to convert glycogen
- a negative feedback to occur
- insulin to be released
- release insulin into the bloodstream
- remove excess glucose by releasing glucagon
- negate the effects of eating the high sugar meal
- 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?
Use the following diagram to answer questions # 37 - 41.
The diagram represents the
Which letter represents the corpus luteum?
- prostate gland
Implantation of the fertilized egg takes place during the cleavage phase called
The release of relaxin, the increase of oxytocin levels, and the decrease of estrogen and progesterone levels denote the advancing stage of
- child birth
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
The pairing of similar chromosomes is called
- prophase I in meiosis
- anaphase I in meiosis
- prophase in mitosis
- anaphase in mitosis
- crossing over
Use the following information to answer questions # 70 - 71.
The genotype of the black, long haired female guinea pig is
In order to study the effects of alleles within the human population, a researcher would require which statement as a step in the research?
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?
- reading about the various types of nucleotides
- separating the living from the dead organisms
- collecting personal data from human sources
- taking the temperature of the test subjects
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?
- Snapdragons are an inferior type of plant to selective breed.
- Colour in snapdragons is due to intermediate inheritance.
- Pink colouration is a result of codominance.
- The snapdragons are pink dominant plants.
An E. coli bacterium that has a section of DNA from a human pancreas cell spliced into its sequence will
- produce insulin along with its own proteins
- die due to the change in its DNA structure
- continue its own natural functions
- produce only insulin
