Answer:
The diagnostic results and history findings that correlate with aplastic anemia are: White blood cell (WBC) count being less than 1,000/µL (1 ×109/L)
, a platelet count of 50 ×103/µL (50 ×109/L)
, recent bout with mononucleosis viral infection
, and completed chemotherapy for leukemia in the past year.
Explanation:
<u>Aplastic anemia occurs when the body isn't producing enough blood cells, which leads to fatigue and a higher risk of infections and unstoppable bleeding.</u>
The most common form of aplastic anemia <u>occurs when the immune system attacks the stem cells in the bone marrow</u>, which can happen when: a) one is exposed to toxic chemicals, b) one went through chemotherapy, c) having an autoimmune disorder, or d) one suffered from a viral infection.
The correct answer is: asexual reproduction via spores
Sporogenesis is the type of asexual reproduction which includes production of reproductive cells - spores, and the growth of a new organism from them. Spores can be produced by bacteria, fungi, algae, and plants. Spores are beneficial for a species that live in an area prone to droughts because spores can do through the resting, or dormant stage. Dormant stage can last until period of unfavourable conditions stops.
