Answer:
Environments on Earth are always changing, and living systems evolve within them. For most of their history, human beings did the same. But in the last two centuries, humans have become the planet’s dominant species, changing and often degrading Earth’s environments and living systems, including human cultures, in unprecedented ways. Contemporary worldviews that have severed ancient connections between people and the environments that shaped us – plus our consumption and population growth – deepened this degradation. Understanding, measuring, and managing today’s human environmental impacts – the most important consequence of which is the impoverishment of living systems – is humanity’s greatest challenge for the 21st century.
Answer:
Plants can't use N2 as is so the first option is wrong. They do have relationships with bacteria that live in nodules of the root and convert the nitrogen into ammonia, a usable form for the plants. So the second option is correct. There are bacteria living in the soil as well that convert nitrogen to ammonia so technically option 3 is also correct. Again, nitrogen if present in water would be in the form N2 which is not usable by plants so 4 is wrong.
These are correct:
use bacteria to convert nitrogen to usable form
In obtain usable nitrogen compounds from the soil
Answer:
Explanation:
cardiovascular system is the circulatory system, it permits the circulation of blood and allows for transport of nutrients such as amino acids and electrolytes, oxygen and carbon dioxide gases, hormones, and blood cells in the body. It also helps the body to provide nourishment and fight against diseases and maintain homeostasis.
It is consider an high way because of its function. An high way allows for free passage, with often time no obstruction this is what cardiovascular system does they allow for movement of blood and essential nutrient in the body system for effective function of our body.
The appropriate title of the scatter plot is solubility curve of sugar
The independent variable is temperature
The dependent variable is mass of sugar in grams that can dissolve in 100 mL of water
The solubility curve is a graph of the amount of solute dissolved in a given volume of solvent against temperature.
The solubility of the solute is plotted on the vertical axis while the temperature is plotted on the horizontal axis.
The independent variable is the temperature while the dependent variable is mass of sugar in grams that can dissolve in 100 mL of water.
