If u have no white blood cells left, what does this mean?
olga2289 [7]
White blood cells fight infections from bacteria, viruses, fungi. and other pathogens (organisms that cause infection). One important type of white blood cell is the neutrophil. These cells are made in bone marrow and travel in the blood throughout the body. They sense infections, gather at sites of infection, and destroy the pathogens.

When the body has too few neutrophils, the condition is called neutropenia. This makes it harder for the body to fight off pathogens. As a result the person is more likely to get sick from infections. In general, an adult who has fewer than 1,000 neutrophils in a microliter of blood has neutropenia.

If the neutrophil count is very low, (fewer than 500 neutrophils in a microliter of blood), it is called severe neutropenia. When the neutrophil count gets this low, even the bacteria normally living in a person's mouth, skin, and gut can cause serious infections.

Suppose no crossing-over takes place. Use step 5 (anaphase 1) to explain why meiosis will still increase genetic variation.
MissTica

Meiosis increases genetic variation due to random segregation which occurs.

In anaphase I of meiosis, the homologous pairs (one maternal and one paternal chromosome) are moved apart to opposite ends of the cell and this process occurs random. This allows the formation of gametes with different sets of homologues. In this phase sister chromatids remain attached at their centromeres (not segragated as in mitosis).
