using the chart at the beginning of the animation and your knowledge of cells, what stage of the cell cycle do most cells spend the majority of their lives?
If a cell is placed in a hypertonic solution then?
Answer:
If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
Explanation:
what is the main artery that carries blood to your brain
put the life cycle of an erythrocyte in order, beginning with their formation in red bone marrow.
Answer:Correct: 1
Erythrocytes form in red bone marrow.
Correct: 4
Hemoglobin is converted to biliverdin.
Correct: 3
Erythrocytes are phagocytized in the liver and
spleen.
Correct: 2
Erythrocytes circulate for 120 days in the bloodstream.
Explanation:
The life cycle of an erythrocyte (red blood cell) involves several stages. Here's the order of the life cycle, beginning with their formation in red bone marrow:
1. Hematopoietic Stem Cell: Erythrocytes are derived from hematopoietic stem cells in the red bone marrow. These stem cells have the potential to differentiate into various types of blood cells, including erythrocytes.
2. Proerythroblast: Hematopoietic stem cells differentiate into proerythroblasts, which are the earliest precursor cells committed to becoming erythrocytes. Proerythroblasts undergo several divisions to produce cells of the erythroblast series.
3. Erythroblast Stages: Erythroblasts progress through several stages of development, including basophilic erythroblast, polychromatic erythroblast, and orthochromatic erythroblast.
4. Reticulocyte Formation: The orthochromatic erythroblast matures into a reticulocyte. Reticulocytes still contain some organelles but lack a nucleus. They are released into the bloodstream and enter circulation.
5. Circulation: Reticulocytes circulate in the bloodstream for about 1-2 days. During this time, they lose their remaining organelles, and their reticulated appearance disappears as they become mature erythrocytes.
6. Mature Erythrocyte: Reticulocytes mature into mature erythrocytes, which are specialized cells optimized for oxygen transport. Erythrocytes have a biconcave shape, lack a nucleus, and are packed with hemoglobin.
7. Functional Period: Mature erythrocytes have a lifespan of about 120 days in circulation. During this time, they transport oxygen from the lungs to body tissues and carry carbon dioxide from tissues to the lungs for exhalation.
8. Removal: Aging or damaged erythrocytes are recognized by macrophages in the spleen, liver, and bone marrow. These macrophages phagocytose the erythrocytes, breaking them down and recycling their components.

what are the two major anatomical subdivisions of the nervous system?
Answer: The nervous system has two main parts:
The central nervous system is made up of the brain and spinal cord.
