Can someone please explain why food that has been kept at room temperature for a few hours is more likely to cause food poisoning than food that has been kept in the refrigerator?
Answer:
Because food kept at room temperature is somewhat exposed to air, and sometimes, the air can contain dangerous chemicals that were perhaps accidentally released, whereas food in the refrigerator doesn't apply to that problem.
Explanation:
Hope this helps, and please mark as brainlest! :)

Of the 30,000,000 species on Earth, how many are lost each HOUR? 10. In conclusion, Bill Nye states that "As more and more species disappear, it's harder and harder to keep an ecosystem in balance because we don't know WHAT?
Answer:
4. food, shelter and water
5. Sabre-toothed Cat and Woolly Mammoth
6. food and water resources
7. World Ocean
9. 3 specie
Explanation:
All living things depend on their environment that supply food, shelter and water that is necessary for their survival. Sabre-toothed Cat and Woolly Mammoth are the two species that have gone extinct due to unfavourable environmental condition. The best way to wipe out a species is to remove food and water resources. The largest ecosystem in the world is World Ocean where two third of all species live. Of the 30,000,000 species on Earth, three species are lost each hour. In conclusion, Bill Nye states that "As more and more species disappear, it's harder and harder to keep an ecosystem in balance because every specie in the ecosystem balances other specie.
1. The ecosystem is defined as the relation of plants and animals, which depend on each other and work efficiently with the surrounding. For an ecosystem to be healthy, the diversity of the organisms are necessary and proper availability of resources.
2. The four types of the ecosystem are terrestrial, artificial, lentic, and lotic. Terrestrial refers to the ecosystem on land, artificial ecosystems can be human-made, lentic and lotic are the types of aquatic ecosystems.
3. In the video, Bill Nye was trying to demonstrate that everything depends on its building block and resources.
4. The biotic components of the ecosystem depend on food, shelter, and water.
5. Extinction refers to the complete elimination of an organism due to natural or human-made factors. Examples of extinct animals are the Wolly mammoth and Dinosaurs.
6. The best way to wipe out species is the change of ecosystem or the habitat in which the organism is thriving.
7. The largest ecosystem in the world is the ocean, where the majority of the species are found and some of them are yet to explore.
8. The biodiversity can be increased by increasing vegetation, diversifying the resources, making shelters available, and plenty of water.
9. Each hour approximately 3 species are lost. It can be due to natural calamity or human factors.
10. The preservation of the ecosystem is necessary, and the soon endangering of the species will lead to unbalance of the ecosystem, as species depend on each other.

Can anyone help? Please, Its very much needed. I can't move to the next part without this
Answer:
Biodiversity is defined as the variety of life forms existing on the planet and the number of species living within an area. The notion also covers the way diversity changes over time and moves from one location to another (“Facts on biodiversity,” n.d.). There is terrestrial and marine biodiversity that includes species living on Earth and in the sea. A number of species dwelling in a particular area helps to monitor the aspects of biodiversity. Maintaining biodiversity is important for people’s well-being since it plays a significant role in the contribution to human health and provision of raw materials. However, currently people often face the loss of biodiversity. Today this process is happening at a much faster pace than it did 50 years ago (“Facts on biodiversity,” n.d.). As a matter of fact, around 90 percent of all the fish on the planet was exploited within the last 50 years, a quarter of bird kinds were killed, and 70 percent of forests was destroyed. In addition, extinction threatens 18 percent of all mammals, 5 percent of the fish, and 8 percent of plants. Thus, it is possible to assume that the loss of biodiversity on Earth, which takes place nowadays, is directly linked to anthropological factors, including overhunting, overfishing, consumerism, and agricultural practices.
Explanation:
What animal is the closest cousin to dolphins. Explain the proof behind this evolutionary connection.
Sharks and dolphins are not closely related, and their comparable body types were not inherited from a single ancestor. Their dorsal fins, flippers, and sleek bodies are the consequence of convergent evolution.
What animal is the closest cousin to dolphins?According to a team of scientists, an extinct deer-like creature the size of a fox or raccoon is more closely related to whales, dolphins, and porpoises than the hippopotamus, which is the assumption made by the public.
You might not be aware of the intimate relationship between dolphins and whales. The zoological group Cetacea is made up of mammals including whales, dolphins, and porpoises.
There are 36 species of dolphin in the Delphinidae family. Because several dolphin family members share the word whale in their common name, it can occasionally be confusing.
Even-toed ungulates like camels and cows are today's closest living cousins of dolphins, with the modest hippopotamus being the next-closest.
Therefore, Sea turtles animal is the closest cousin to dolphins.

Write a paragraph about air, land and water pollution.
Answer:
AIR POLLUTION:
This tern is not something new, it has been existing since he time of industrial revolution where in big chimneys are pointed out in the air which releases harmful gases into the atmosphere. This phenomenon has been increasing since then as the industries have been developing simultaneously. Today, air pollutants have shown a great effect on plantations, health and life, decreasing the enjoyment of living, rising medical costs, causes global warming and also causes the destruction of the ozone layer.
One of the major causes of air pollution is the release of carbon di oxide into the atmosphere. This happens because of deforestation and fossil fuel burning. Sulfur dioxide is another main air polluter and is released into the atmosphere by the burning of sulfur containing compounds of fossil fuels. Sulfur dioxide is very harmful for the humans on high concentration and sulfur in the atmosphere is the main cause of acid rains. Chlorofluorocarbons also contribute to air pollution by reducing the ozone layer in the stratosphere. CFC’s are produced by the burning of plastic foam items, leaking refrigerator equipment and spray cans.
WATER POLLUTION:
Contamination of available natural water by industrial wastes and other waste products can be defined as water pollution. Factors causing water pollution can be categorized into two different groups; Point sources and Non- point sources.
Point sources are easy to identify and control. Some point sources of water pollution include waste products from factories, waste from sewage, waste from power plants , waste from underground coal mines and waste from oil wells. They are called point sources because these are the direct sources of water pollution and be reduced and monitoredNon- point sources are ambiguously defined and are much harder to control. The term non -point source encompasses a large range of sources like when rain and snow moves through the ground and picks up major pollutants and mover towards a major body of water, the runoff of fertilizers from farms animals and crop lands, air pollutants getting washed or deposited to earth, and storm water drained from streets parking lots and lawns.
LAND POLLUTION:
The contamination of and with different kinds of wastes is called land pollution. The major causes of land pollution are construction, domestic waste , industrial waste and agriculture.
The rising construction of building takes away the trees that takes away the homes of the animals living there. As there are more and more people inhabiting on our planet, the demand for food increases and the forests are cut down to make farm lands. In addition, Herbicides, pesticides, artificial fertilizers and animal manure are washed into the soil and pollute it. Tons of domestic waste is dumped everyday from homes offices etc. They can be recycled or burnt in incinerators. There are still more waste machinery products such as refrigerators and washing machines that are dumped in landfills simply because they cannot be recycled. Plastic factories, oil refineries, nuclear waste disposals, and large animal farms, all lead to land pollution.
WAYS TO STOP POLLUTION:
We can help to reduce global air pollution and climate change by few ways:
Driving a car that gets at least 35 mpg, walking, biking, and using public transportation, using CFL bulbs over incandescent bulbs, buying only energy efficient appliances, recycling newspaper, aluminum, and others, planting trees, avoid purchasing products that contains CFC’s, supporting much stricter clean air laws and enforcement of international treaties to reduce ozone depletion and slow global warming

Big Bang theory is a theory that endeavors to explain the origin of the universe. It stipulates that the universe exploded from a singularity and continues to expand today
Explanation:
Hope it helps:)
The statement 'the universe is continually heating up and gaining energy' is NOT true about the evidence to support the origin of our Universe.
The evidence states that the Universe is continually expanding, thereby celestial bodies are moving away from each other.In this regard, it has been proposed that a faster expansion rate might be due to an unknown force that is pulling galaxies apart.Moreover, it has also been suggested that as the Universe is expanding, its temperature slowly declines (i.e., the universe is becoming cooler) and loses energy.In consequence, the Big Bang Theory about the origin of the Universe states that it cools down as it expands.In conclusion, the statement 'the universe is continually heating up and gaining energy' is NOT true about the evidence to support the origin of our Universe.
