Answer:

Explanation:

Colour of objects. The colours we see are the wavelengths that are reflected or transmitted. For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum. Red light is the only light that is reflected from the shirt.

Rank from the first to the last steps to describe the correct order of events of erythrocyte death.

timama [110]

Answer:

1. erythrocyte becomes trapped in the sinusoids of spleen.

2. Spleen macrophages digest the erythrocytes.

3. Hemoglobin is broken down into amino acids, iron and bilirubin.

4. Iron ions and amino acids are recycled to make new hemoglobin in red bone marrow. Bilirubin is sent to liver for excretion.

Explanation

Aging erythrocytes are trapped in the sinusoids of the spleen, where they are digested by macrophages. Within the macrophage, hemoglobin is broken down into amino acids, iron ions, and bilirubin.

Iron ions or heme ion and amino acids then move through the blood to the bone marrow, where they are recycled and used to create new hemoglobin. Bilirubin travels with the help of the blood to the liver, where it is modified and then excreted.

thus, the correct order is :

1. erythrocyte becomesrapped in the sinusoids of spleen.

2. Spleen macrophages digest the erythrocytes.

3. Hemoglobin is broken down into amino acids, iron and bilirubin.

4. Iron ions and amino acids are recycled to make new hemoglobin in red bone marrow. Bilirubin is sent to liver for excretion.

Michelle and George are studying the forces and motion of a 0.8-kg low friction cart on a horizontal table. They use a spring sc

Helen [10]

Table 1: The horizontal pulling forces (F) and resulting acceleration (a) for the cart.

The cart experiences no motion when there is 0.1 N of horizontal force, so F=0 in this case. When one uses Newton's Second Law to find the acceleration caused by each force, it becomes clear that every row in the chart represents a horizontal force of approximately F=20 N. The best fit for the missing value is F=-30N.
