Answer:
The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. ... The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane regulates the transport of materials entering and exiting the cell.
A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it moves hazardous materials out of the cell and carries nutrients into the cell.
What is a cell membrane?All cells' interiors are protected from the outside world by a biological membrane called the cell membrane. A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes. One is to move substances out of the cell that are toxic as well as nutrients into the cell.
Glycerophospholipids, molecules made of glycerol, a phosphate group, and two fatty acid chains, are what make up cellular membranes, including plasma membranes and internal membranes.

Pick one sentence or paragraph from the article, and explain how it supports the idea that science is an evolving discipline that depends on repeated testing.
Answer:
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.

Answer:
she is wrong , its c
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.
What will happen in result to it ?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.

Low precision and low accuracy best describe the archer's results. So the correct option is A.
Who is an archer?Archery is a sport that involves firing arrows with a bow at inanimate objects or animals during a hunt.
With the exception of Australia, the bow has been a primary tool of combat and the hunt from prehistoric times.
Ancient Egyptians and Greeks also engaged in recreational archery in addition to military archery, an example of the latter being the contest in which Odysseus triumphed and gained Penelope's hand.
Large portions of Asia were ruled by horse-mounted archers such as the Huns, Seljuq Turks, Mongols, and others for around 15 centuries beginning in the first century CE.
During the Hundred Years' War (1337–1453), English longbowmen earned magnificent military successes, while the crossbow gained popularity throughout continental Europe, particularly in Switzerland, some regions of Germany, France, and the Low Countries.
Therefore the correct option is A.

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.

a typical eukaryotic cell has enough available atp to meet its needs for about 30 seconds. what is likely to happen to an individual when they exhaust their atp supply?
Eukaryotic cells rely on the molecular energy of ATP to sustain all of the reactions necessary to maintain life, in the absence of ATP, these reactions would come to a halt, and the cell would inevitably die.
ATP is a molecular compound that provides the energy needed by most cells to survive. ATP represents Adenosine triphosphate, which is an organic compound that provides energy to drive the essential metabolic reactions of living cells, such as:
Muscle contractionsNerve impulsesChemical synthesisNutrient absorbtionIn the situation in which a cell was to run out of ATP, these reactions would stop, given that they require ATP to function. This means that the cell would not be able to send or receive nerve signals, absorb the nutrients it needs, or even create necessary compounds such as proteins. The stoppage of these functions would lead to the death of the cell.
