Spherocytosis is a human blood disorder associated with a defective cytoskeletal protein in the red blood cells (rbcs). what do
Alex17521 [72]
In spherocytosis, there is a defect in the membrane proteins of the red blood cells, specifically ankyrin and spectrin. These membrane proteins contribute to the biconcave shape of red blood cells therefore the loss of these proteins will lead the red blood cells to lose its biconcave shape--leading to abnormally shaped red blood cells (spheres) hence the name. This can lead to premature destruction of red blood cells and jaundice due to hyperbilirubinemia. Spherocytes do not hold oxygen and carbon dioxide well as spherocytes have a decreased surface area.

Can someone write the first paragraph
Katena32 [7]

Hii!!

The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres

2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin

● The order of the stages of mitosis can be remembered using the mnemonic PMAT.

Hope this helps!! if it has pls mark me as the brainliest Xd :D

The answer would most likely be sodium because carbon is a plants food, phosphorus is a nutrient in soil, hydrogen is air, but sodium does not have a place in a plant:)
