Question 1
Which statement is not true regarding fungi? Fungi are all prokaryotic cells. This is not true because fungi are eukaryotic in nature defining why their cells contain nucleuses which are covered by a membrane. In contrast, bacteria cells lack these membranes covering their nucleus, making them prokaryotic.
Question 2
Asexual reproduction involves the formation of: Genetically diverse daughter cells. In asexual reproduction, only a single parent is involved. Reproductive cells do not undergo fusion and the off springs are usually virtually identical to the parent.
Question 3
Fungi that support growth at two different temperature environments are called? Dimorphic or biphasic. Dimorphic fungi represent organisms that attain equilibrium between spherical and polarized growth regardless of the environmental conditions such as temperature.
Question 4
Disease treated with Intravenous Amphotericin B is Cryptococcosis. This disease is brought about by a fungus known as Cryptococcus neoformans and usually affects persons with immune systems that are weak, and they are advised to evade contaminated environments.
Question 5
Which statement is not true regarding protozoa? Reproduction, with a few exceptions, occurs by the asexual process of mitosis. Protozoa normally reproduce sexually, but this is not the case in free-living protozoa which undergo sexual reproduction only in adverse conditions such as depletion of food and uncondusive environments.
Question 6
Which is true regarding Amoebas? They have been implicated in corneal infections in contact lens wearing patients. Amoeba has been indicated to be a disease causing organism, which has adverse effects on human corneas. The most common species related to the disease is known as keratitis.
Question 7
Sporozoa: Are so named because they form spores. Comparatively, Sporozoa are harmless to human health. Unlike other bacteria, Sporozoa have no benefit in any way. Contrary to protozoa, they lack motile organs resulting to quiescent nature.
Question 8
Which is not true regarding pathogenic agents? All pathogens have been well characterized and it’s not likely any new pathogens will be found. Pathogenic agents transmit in indirect and direct manners, entering susceptible hosts through portals of entry hence causing diseases. An example is the transmission of the cold virus just after the host starts to sneeze.
Question 9
Complement: An antigenic blood component. Through probable mechanisms, complement components usually attach red blood cells in the in vitro or in vivo ways. Binding complements are specific for red blood cells antigens which may lead to sensitizations due to the transfusions.
Question 10
What is not true regarding antigens: The immunogenicity of antigens refers to their relative ability to stimulate the cells of the immune system. Usually, antigens have characteristics of combining together with antibody that stimulate the immunity responses. These agents are referred to as immunogens.
Question 11
Which is true regarding lymphocytes? Lymphocytes mature in the forming fetus in either the thymus or the bone marrow, depending on the ultimate type of lymphocyte being formed. Lymphocytes represent the blood cells that deal with the recognition of antigens and also the production of antigen.
Question 12
Agglutinins are antibodies that react with viral capsids and prevent viruses from entering their host cells. They are gamma globulin molecules which attach …
