Explain why it would not be possible to accurately measure hemoglobin concentration if the RBCs were not first lysed.
docker41 [41]

Because hemoglobin is compartmentalized inside the RBCs, lysis of RBCs is necessary for accurate measurement of hemoglobin levels.

<h3>Measure of hemoglobin concentration</h3>

Hemoglobin is a complex found in blood which is responsible for transporting oxygen to cells of the body.

Hemoglobin is composed of heme and the proteins alpha and beta globin.

Hemoglobin is found within the cytoplasm of red blood cells.

Since hemoglobin is compartmentalized inside the RBCs, lysis of RBCs is necessary for accurate measurement of hemoglobin levels.

Answer:

Explanation:

The main  function of the plasma membrane is to protect the cell from its surroundings. Made of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules it also regulates the movement of substances in and out of cells. Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. Membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors, which then trigger intracellular responses. Some viruses, such as Human Immunodeficiency Virus (HIV), can intercept  these receptors to get into the cells, causing infections.

How is water necessary for the structure of a green plant?
ch4aika [34]
Like all life on earth, plants need water to survive and grow. Indeed, like humans, water is the primary element that makes up the structure of plants. Human bodies are comprised of around 70 percent water, but in plants this proportion can be as much as 95 percent. Water is also essential to the way a plant receives nutrients and provides energy for itself. Thus, water is arguably the most essential substance required by plants. That is why many elements of permaculture design – from using swales and contouring to slow runoff from the land and allowing it to sink into the soil to mulching to prevent evaporation of moisture from the soil surface – emphasis the preservation of water so that it can be provided to plants.

hope this helped :)
