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.

The light reactions of photosynthesis supply the Calvin cycle with a. Light energy. b. CO₂ and ATP. c. H₂O and NADPH. d. ATP and
Thepotemich [5.8K]

The light reactions of photosynthesis supply the Calvin cycle with (d) ATP and NADPH.

Light reactions are photochemical reactions which are directly driven by light. They are responsible for the synthesis of ATP as well as NADPH.

Light reactions take place in the membranous system that is present  within the chloroplasts. The membrane system consists of grana, the stromal lamellae and the matrix stroma.

The products of light reaction include ATP, NADPH as well as O₂. However, ATP as well as NADPH are used in driving the processes which result in the production of sugars, whereas O₂ diffuses out of the chloroplast.
