Answer:
Autoimmune hemolytic anemia
Explanation:
Autoimmune hemolytic anemia (AIHA) occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst (lyse), leading to an insufficient number of oxygen-carrying red blood cells in the circulation.
Answer: True
Explanation:
The cardiovascular system includes the heart and blood vessels. The function of the heart is to pump out oxygenated blood via blood vessels to all the parts of the body. The blood vessels arteries, veins and capillaries contribute to the transfer and distribution of the blood.
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.
