Explanation:

12K is the boiling point of the chemical .

The boiling point of any liquid changes to the applied pressure the normal boiling point is the temperature at which the vapor pressure is equal to the standard sea-level atmospheric pressure .At sea level, water boils at 100° C (212° F).The boiling point of a liquid is the temperature at which its vapor pressure is equivalent to the pressure of the gas above it.

Boiling point is used to identify and classify a given compound. A liquid boils when its vapour pressure is equal to the atmospheric pressure. Vapour pressure is also defined  by the kinetic energy of a molecule. Kinetic energy is dependent on the temperature, mass and velocity of a molecule.

Organism C makes its own food is examples of several ways organisms obtain energy.

Energy is referred to by scientists as the capacity for work. People have figured out how to transform energy from one form to another and then use it to accomplish tasks, making modern civilization possible.

Walking and bicycling, driving cars on roads and boats through water, cooking meals on stoves, making ice in freezers, lighting our homes and workplaces, producing goods, and sending astronauts into space all require the usage of energy.

Energy is capable of changing its forms. For instance, a person's body stores chemical energy from the food they consume until they may use it as kinetic energy when working or playing.

Therefore, Organism C makes its own food is examples of several ways organisms obtain energy.

Answer:

The whale sharks niche in the environment is essentially population control. The whale shark spends all day eating and without it the populations of krill and plankton would increase by a large amount.

Explanation:

Whale sharks have a broad distribution in tropical and warm temperate seas, usually between latitudes 30°N and 35°S. They are known to inhabit both deep and shallow coastal waters and the lagoons of coral atolls and reefs. Australia is one of the most reliable locations to find whale sharks. It is very difficult to conduct research on the shark's role in the ecosystem so scientists aren't sure what would happen if sharks became extinct. ... If the whale shark becomes extinct, there might be an increase in plankton. However, plankton are also eaten by several species of whale. Whale sharks are one of the most amazing animals in the world — and while they may be sharks, they're also one of the most gentle fish in the sea. In fact, whale sharks are so gentle, they're completely safe to swim around. Our Whale Shark Encounter tour gives you the opportunity to do just that.

PLEASE MARK ME THE BRANIEST THANK YOU :)

Explanation:

The next decades are crucially important to putting the world on a path of reduced greenhouse gas emissions.

By the end of the century, demand for energy will have tripled under the combined pressure of population growth, increased urbanization and expanding access to electricity in developing countries. The fossil fuels that shaped 19th and 20th century civilization can only be relied on at the cost of greenhouse gases and pollution.

A new large-scale, sustainable and carbon-free form of energy is urgently needed. The following advantages make fusion worth pursuing.

Abundant energy: Fusing atoms together in a controlled way releases nearly four million times more energy than a chemical reaction such as the burning of coal, oil or gas and four times as much as nuclear fission reactions (at equal mass). Fusion has the potential to provide the kind of baseload energy needed to provide electricity to our cities and our industries.

Sustainability: Fusion fuels are widely available and nearly inexhaustible. Deuterium can be distilled from all forms of water, while tritium will be produced during the fusion reaction as fusion neutrons interact with lithium. (Terrestrial reserves of lithium would permit the operation of fusion power plants for more than 1,000 years, while sea-based reserves of lithium would fulfil needs for millions of years.)

No CO₂: Fusion doesn't emit harmful toxins like carbon dioxide or other greenhouse gases into the atmosphere. Its major by-product is helium: an inert, non-toxic gas.

No long-lived radioactive waste: Nuclear fusion reactors produce no high activity, long-lived nuclear waste. The activation of components in a fusion reactor is low enough for the materials to be recycled or reused within 100 years.

Limited risk of proliferation: Fusion doesn't employ fissile materials like uranium and plutonium. (Radioactive tritium is neither a fissile nor a fissionable material.) There are no enriched materials in a fusion reactor like ITER that could be exploited to make nuclear weapons.

One current ethical issue in marine science is the use of genetically modified organisms (GMOs) in aquaculture.

Genetically modified organisms (GMOs) are living organisms whose genetic material has been artificially altered in a laboratory using genetic engineering techniques.Here are two perspectives supporting each side of the issue:

Perspective 1: According to a report by the World Health Organization (WHO), GMOs have the potential to reduce the environmental impact of aquaculture by decreasing the need for wild fish as feed, reducing the use of antibiotics, and decreasing the risk of disease outbreaks.

Perspective 2: Opponents of GMOs in aquaculture argue that they pose a significant risk to wild fish populations and the environment. According to the Ocean Conservancy, GMO fish can escape from fish farms and breed with wild fish, potentially altering the genetic makeup of natural populations and harming biodiversity.

Therefore, use of GMO's is profitable as well as hazardous for the environment.

Answer:

7.0 km/hr

Explanation:

A student who was training for a cross country race jogged for 2.0 hours and covered a distance of 14.0 kilometers. The average speed is 7.0 km/hr. Hence option B is correct.

Training is defined as the process of educating or training your staff on a certain task in order to increase their performance or expertise. There are three main goals of training from the perspective of the individual employee: Increase the person's awareness level. Boost a person's proficiency in one or more of their areas of specialization. increase the drive for someone to do their work successfully.

Average speed is defined as the entire distance that an object has gone in a given amount of time.

It can be expressed as

Speed = Distance / time

Speed =  14.0 km / 2.0 h

Speed = 7.0 km / hr.

Thus, a student who was training for a cross country race jogged for 2.0 hours and covered a distance of 14.0 kilometers. The average speed is 7.0 km/hr. Hence option B is correct.

In multicellular organisms, cell growth and division are very controlled. Some cells like muscle and nerve cells stop dividing after maturity. Other cells like Skin and blood cells grow and divide rapidly through life. Cyclins are proteins that regulate the timing of the cell cycle, "telling" the cell when to divide. If cells stop responding to regulation, uncontrolled cell growth can lead to cancer.
