Answer:
Option (A), (C) and (D).
Explanation:
A mucosa is the membrane that mainly lines the body cavities and covers the internal surface organ of the body. The mucosa is present in the whole intestinal tract.
This mucosa plays an important role in the immunity of the organisms. The mucosa contains both the B cells and T cells that plays an important role in humoral immunity and cell mediated immunity. The neutrophils plays an important role in the inflammation and also phagocytose the cell.
Thus, the correct answer is option (A), (C) and (D).
Answer:
3. A client receiving chemotherapy and a client with chronic obstructive pulmonary disease (COPD) coughing yellow sputum.
4. A client with pelvic inflammatory disease (PID) and a client with coffee ground emesis.
5.Two clients with tuberculosis.
Explanation:
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs and this disease is not contagious, the yellow sputum indicates the presence of a potentially pathogenic bacteria (infection in your lungs), but it will not be transferred through the air. A person on chemotherapy treatment has cancer which is also not contagious so these two people may be placed in the same room.
Pelvic inflammation disease (PID) is an infection of the female reproductive organs and is occurs when sexually transmitted bacteria spread from the vagina to the uterus, fallopian tubes or ovaries. Coffee ground emesis is a type of vomit that looks like coffee grounds meaning there is old blood in the vomit (a person is vomiting blood). These two are not contagious so the two people can be put in a room together.
Tuberculosis (TB) is an air borne disease that infects mainly the lungs and people may get infected by inhaling the TB bacteria (Mycobacterium tuberculosis). So when someone with untreated TB coughs or sneezes, the air is then filled with droplets containing the TB bacteria, if a person who does not have TB inhales these droplets they will be infected with the bacteria as well this is called droplet infection. If two people with TB are in the same room together there is no risk of one affecting the other because they are both already infected by the bacteria, unlike placing someone without TB with a TB patient, that person may be at risk of inhaling the droplet and being infected.
Heart failure is a condition in which the heart does not pump enough blood to meet the body’s demands (the heart does not pump blood the way it should) and an airborne infection isolation room is a single occupancy care space that’s designed to isolate airborne pathogens to a safe containment area, so there can only be one person in that room we cannot put the heart failure patient in there. Patients in these rooms have serious illnesses that may pose a risk to hospital staff and these rooms are used to protect the public from the spread of these diseases.
Varicella also known as chicken pox, is a very contagious disease caused by the varicella-zoster virus, and pertussis also known as whooping cough is also a highly contagious respiratory disease caused by the bacterium Bordetella pertussis, so one cannot put two people with different highly contagious diseases in one room.
How do cells acquire homologous chromosome pairs that carry the alleles that are independently assorted? answer: Fusion of gametes.
Answer:
D. all options are correct
Explanation:
- There is a trade-off between the size of gametes and the number of gametes.
- The larger the gamete, the less mobile it is
- The probability that a zygote survives increases with its size, and the size of the zygote is a function of the sizes of the fusing gametes
Answer: the device is called an Electroencephalography machine.
Explanation:
An EEG or Electroencephalography is an electrophysiological monitoring method to record electrical activity of the brain.
