Answers
Septic tanks are used for waste water management in homes. It can potentially contaminate water by (A), (B) and (C).
What is septic tank?Septic tanks are watertight containers that allow solids to settle to the bottom and less dense liquids to float, allowing bacteria to decompose solid waste in home wastewater.
Since septic tanks can't pump wastewater to a water treatment facility, they need some maintenance.
Septic tanks in rural areas can contaminate drinking water due to poor water systems. In rural areas, water comes from wells, rivers, and streams, so if a septic tank is too close, it could contaminate the water. Wastewater can contaminate drinking water.
Due to rising sea levels and heavy rainstorms, septic tanks near coastlines may contaminate drinking water. This prevents soil from treating septic tank wastewater before it contaminates groundwater and drinking water.
If a septic tank is clogged or has a high volume of water, it may saturate the ground with sewer water and leak into groundwater, contaminating any nearby water source with pathogenic germs.

If the CO2 level in a jar with plant decreasing then decomposition occurs. that means the plant will die.
What is decomposition ?Decomposition literally means "to break down." Usually, it refers to the breakdown or rupture of a complex organic substance into a more straightforward inorganic substance. It is a crucial and vital component of the ecosystem's processes. Decomposition is therefore a metabolic process that consumes complex chemicals as raw materials, processes them, and then transforms them into simpler compounds.
Decomposers, which include bacteria, fungi, and a few other microorganisms, are those who start the decomposition process. To stay alive, they consume dead organisms.
Dead and decaying animals and plants are used as the raw materials for the breakdown process that results in the production of nutrients, carbon dioxide, water, and other things. Raw elements like dead plants, animals, and their remains are referred to as detritus. Microbes then break this down.

When populations reach their carrying capacity and even exceed it, they are expected to decrease in size because of the lack of available resources. In this example, the Europe population is expected to get smaller between 2010 and 2050.
What is the carrying capacity?Carrying capacity is the capability of the environment to support a population.
Commonly a growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.
Environments have limited resources, and the population growth per capita rate decreases as population size increases.
Eventually, the population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that coincides with the population size (N) when natality rate and mortality rate are equal to each other. This is the equilibrium point.
If N < K, the population can still grow. When N approximates to K, the population's growth speed decreases. When N = K, the population reaches equilibrium, When N > K, the population must decrease in size because there are not enough resources to maintain that size.So when the population size exceeds K, the carrying capacity makes the population decrease in size. This is because there are not enough resources for this population to survive.
In the exposed example, we can see that
Until 2010, most populations were still growing since they had not reached their carrying capacity yet. From 2010 to 2050, many of them are expected to reach K and stop increasing in size.
However, there was one population that by the year 2010 had already reached its carrying capacity point, K. Europe's carrying capacity seems to be nearly 900 million people. Between 2000 and 2020, the population reached this number and stopped growing. After 2020 it started to decrease.
Europe is the only region whose population seems to be decreasing by the year 2050.
So Europe population is expected to get smaller between 2010 and 2050.

if pain is increased the females will tolerate the pain better because women experience abdominal pain on a monthly basis whats the independent variable
Answers
According to Fillingim, "men have higher levels of testosterone, which in some studies has been shown to be protective against pain or associated with lower pain. whereas women have both higher levels and fluctuations in circulating estrogens and progesterone, and those may contribute to experiencing higher levels of pain.
Do women tolerate pain better than men?
Because females experience abdominal discomfort on a monthly basis, the image for "If pain is increased, females will tolerate the agony better"According to new research, women's acute pain tolerance is more reliable over time than men's.Because they believe that hormonal changes in women create greater long-term unpredictability and less dependability in pain assessments, many researchers don't include women in their studies of pain. Additionally, sex hormones have an impact on pain sensitivity; in women, menstrual cycle stages affect pain tolerance and threshold.Men and women respond to acute pain differently in terms of both the spatial pattern and strength of that reaction, according to imaging studies of the brain. Women rated their average levels of pain as being higher than men's for practically every condition.According to the survey, women often received better marks than males did.Women typically reported higher scores than males when they experienced lower back pain, knee and leg discomfort, or both.Experimental pain models and clinical pain exhibit sex differences in both acute and chronic pain.Although chronic pain is more common in women, the data on how severe it is are less clear.The underlying mechanisms, which include include the role of hormonal and genetic variables, require more research. Graham continues, "Human studies more consistently demonstrate that men have higher pain thresholds than women, and some also demonstrate that men have higher pain tolerance."She adds that another way to interpret these findings is that women are more sensitive to pain.Women may experience pain more intensely than males do because they have more nerve receptors in their bodies, necessitating the adoption of alternative surgical procedures, therapies, or medication dosages to help control their discomfort.

Answer:
carbon
Explanation:
In physics, a system is defined as the portion of the universe that has been chosen for study. Systems may be complex, such as a whole planet, or simple, such as the water inside a pot. The universe outside the system is called the surroundings. A closed system is one that does not exchange matter with its surroundings and does not experience any outside forces. An open system, on the other hand, can exchange matter with its surroundings and does experience outside forces.
The idea of systems and surroundings was not always part of physics. In 1824, the French physicist Nicolas Carnot applied the idea of systems to thermodynamics. A little later, German physicist Rudolf Clausius added the idea of surroundings. Today, system and surroundings are terms applied also to mechanical systems, as well as used in other scientific fields such as biology.
Examples of open systems are common in everyday life. A car driving down a road is a system. The car engine produces exhaust, which is matter passed to its surroundings. Friction between the car and the road is an outside force that acts on the system. Closed systems are rare in everyday life. They are commonly used in physics laboratories to simplify system analysis and calculations.
So, what questions can help someone decide whether the system under consideration is open or closed? The first question to ask is: Does the system exchange matter with its surroundings? If yes, it is an open system. If no, it is a closed system. The second question is: What is the source of the forces experienced by the system? If all forces originate within the system, the system is closed. If forces act on the system from outside of the system, it is an open system.

How does water move up the xylem?
Answers
The water moves up the xylem by the process of Agglomeration.
The tension created by transpiration "pulls" water into the xylem of the plant, pulling it up, much like a straw pulls water up. Agglomeration (water sticking together) pulls the top water toward the pores, so more water molecules fill the gaps in the xylem.
Water molecules in xylem cells strongly attract each other. Due to hydrogen bonding, there is a strong cohesive force between molecules. Thus, a continuous column of water is wicked into the stem by evaporation of the leaves in the transpiration flow.
