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.

In basidiomycete fungi, the nuclei from parents combine in the BASIDIA to make offspring spores. Basidia are microscopic structures but they are generally produced on large fructifications known as fruit bodies.

A basidium is a sporangium localized on the hymenophore of the fruiting bodies in basidiomycete fungi.

In basidia, the nuclei of two parental strains fuse by karyogamy and then divide to reproduce basidiospores.

A basidium generally contains four sexual spores known as basidiospores.

Explanation:

The grass population would decrease. The snake population and hawk population would increase.

The correct answer is option C. . If you were to suddenly double the population of rabbits, the grass population would decrease due to overgrazing by the increased rabbit population.

As a result, the snake population and hawk population would increase due to the increased availability of prey. This is known as a trophic cascade, where changes in one trophic level affect the populations of other trophic levels in the food chain.

Option A and B are unlikely as doubling the population of rabbits would not necessarily cause the populations of the other three species to increase or decrease in a straightforward manner.

Option D is incorrect as there is no direct relationship between the rabbit population and the hawk population in this food chain.

Because the cell structures are so small, to clearly view them, requires a microscope that has a higher power of magnification than light microscopes can prove. This is usually an Electron Microscope.

Electron microscopy (EM) is a technique used to obtain high-resolution images of biological and non-biological specimens. It is often used to investigate the detailed structure of tissues, cells, organelles, and macromolecular complexes. (UMass Chan Med School Website)

From Edmentum:

“Paleontologists used to think that dinosaurs were similar across the continents—at least during the Jurassic period, says Novas. C. diegosuarezi’s mix of features now brings a wrinkle of doubt to that idea.” The paragraph explains that this new dinosaur gives some evidence that the dinosaurs in South America were structurally different from dinosaurs in other areas of the world. According to the paragraph, scientists will need to find and examine more dinosaur fossils from this region before they can support this claim. The claim supports the statement that science requires repeated testing.

Reworded:

“Paleontologists used to think that dinosaurs were similar across the continents—at least during the Jurassic period, says Novas. C. diegosuarezi’s mix of features now brings a wrinkle of doubt to that idea.” Paleontologists used to think all dinosaurs were similar all around the world, but the structure of a specific species of dinosaur made them second guess themselves. It seemed that the dinosaurs in South America were evolving different structures and functions than dinosaurs from other continents. The claim supports that the statement needs more testing.

Explanation:

Answer:According to Novas, "Paleontologists once believed that dinosaurs were identical on all continents, at least during the Jurassic era. The combination of traits on C. diegosuarezi currently casts some doubt on that theory. The structure of a particular species of dinosaur caused paleontologists to reevaluate their previous belief that all dinosaurs were globally identical. It appeared that the architecture and functions of South American dinosaurs were evolving differently from those of dinosaurs from other continents. The claim argues in favor of additional testing for the assertion.

How cells extract energy from glucose in the absence of oxygen. In yeast, anaerobic reactions produce alcohol, while in your muscles, they form lactic acid.

it is advantageous for cells to switch to anaerobic fermentation in the absence of oxygen because Anaerobic processes in yeast produce alcohol, whereas they produce lactic acid in your muscles.

Generally, Once the oxygen is removed from the fermentation vessel and replaced with N2, CO2, etc of the fermentation, anaerobic fermentation begins.

In conclusion, Anaerobic processes in yeast produce alcohol, whereas they produce lactic acid in your muscles.
