The only oral anticoagulant available was
warfarin
Answer:
There is a higher oxygen content in the air of the lungs than that of oxygen-depleted blood and a lower carbon dioxide concentration. This gradient of concentration causes gas exchange during respiration.

Answer:
Explanation:
Invasive species are among the leading threats to native wildlife. Approximately 42 percent of threatened or endangered species are at risk due to invasive species.
Human health and economies are also at risk from invasive species. The impacts of invasive species on our natural ecosystems and economy cost billions of dollars each year. Many of our commercial, agricultural, and recreational activities depend on healthy native ecosystems.
What Makes a Species "Invasive"?
An invasive species can be any kind of living organism—an amphibian (like the cane toad), plant, insect, fish, fungus, bacteria, or even an organism’s seeds or eggs—that is not native to an ecosystem and causes harm. They can harm the environment, the economy, or even human health. Species that grow and reproduce quickly, and spread aggressively, with potential to cause harm, are given the label “invasive.”
An invasive species does not have to come from another country. For example, lake trout are native to the Great Lakes, but are considered to be an invasive species in Yellowstone Lake in Wyoming because they compete with native cutthroat trout for habitat.
Answer: The center vacoule
Explanation:
Vacuoles are membrane-bounded vesicles whose functions vary in different kinds of cells. Mature plant cells generally contain a large central vacuole.
The plant cell central vacuole is a varsatile compartment. It can hold reserve of important organic material such as protein stockpiled and inorganic ions. Many plant cells use their vacuoles as a disposal sites for metabolic by-products that would endanger the cell if the accumulate in the cytosol.
Vacuoles may also help protect the plant against predators by containing compounds that are poisonous or unpalatable to animals.
