What is the difference between a greenhouse gas and a particulate?
Answer:
The main differences between greenhouse gases and air pollutants are how they affect our health and the environment. ... The main problems caused by air pollution occur close to the ground, such as soiling of buildings and producing health effects, but greenhouse gases affect the whole of the atmosphere.
Explanation:
greentree have a air and pollutants help us with our health
Answer:
a green house gas is a gas that contributes to the greenhouse effect by absorbing infrared radiation. Carbon dioxide and chlorofluorocarbons are examples of greenhouse gases while a particulate are microscopic particles of solid or liquid matter suspended in the air

How do igneous
rocks form?
a. compaction and cementation of sediment
b. heating and added pressure to existing rock
c. evaporation of seawater
d. cooling of molten lava or magma
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.
Answer:
cooling of molten lava or magma

ICM.06] Scientific research shows that our global climate is changing as a result of an increase in greenhouse gases. Arctic sea ice is decreasing in both surface area and thickness. Which of the following statements best describes the
consequence of decreasing Arctic sea ice?
The melting of sea ice will decrease the effects of global warming in the area as the ice absorbs heat
O seawater levels wil decrease making t difficult for marine animals to survive.
Animals that rely on the sea le for survival may become extinct as their habitat disappears.
The milder temperatures will allow for greater survival rates for native species
As a result of decreasing Arctic sea ice, animals that rely on the sea level for survival may become extinct as their habitat disappears.
The increase in the atmospheric greenhouse gases means that more radiant energy from the sun that could have escaped back into space is being absorbed, leading to an increase in the global temperature.
The increase in the global temperature means that more Arctic sea ice would be melting and decreasing in size. As the ice melts, the water moves into seas thereby causing a rise in their levels.
A rise in sea level means the disappearance of coastal habitats. Thus, a loss in biodiversity will occur as the habitats of plants and animals disappear as a result of the rise in sea levels.

Which of the following is true about subatomic particles?
The mass of a neutron is equal to the mass of a proton
Neutrons have no charge and are the lightest subatomic particle
Electrons are negatively charged and are the heaviest subatomic particle
Protons are positively charged and the lightest subatomic particle
Answer:
Neutrons have no charge and are the lightest subatomic particle
Explanation:
Nucleus of an atom contains three subatomic particles. These are protons, neutrons and electrons.
Mass of a proton is [tex]1.67[/tex]×[tex]10^{-27}[/tex]kg.
Mass of a neutron is [tex]1.67[/tex]×[tex]10^{-27}[/tex]kg.
Mass of an electron is [tex]9.1[/tex]×[tex]10^{-31}[/tex] kg.
Also, protons are positively charged, neutrons have no charge and electrons are negatively charged.
Therefore, we can conclude that the mass of a neutron nearly equals the mass of a proton.
The basic building block of matter
Answer:
Scientists once thought the most fundamental building block of matter was a particle called the atom. Now we know that the atom is made of many smaller pieces, known as subatomic particles. Every atom contains a central core called the nucleus, made of particles called protons and neutrons.

Which characteristic best explains why lentic ecosystems are more responsive to seasonal changes than lotic ecosystems?
Photosynthetic organisms keep lentic ecosystems warmer during the winter season.
Lentic ecosystems are susceptible to temperature due to their low dissolved oxygen.
Lotic ecosystems have low nutrient levels, making them more sensitive to temperature.
Lentic ecosystems tend to have smaller volumes of water compared to lotic ecosystems.
Lentic ecosystems tend to have smaller volumes of water compared to Lotic ecosystems.
Lentic ecosystem consists of still (stagnant) volume of water and good examples include ponds,lakes, basins etc.
Lotic ecosystem , on the other hand consists of a flowing volume of water and examples include seas, oceans, rivers etc.
The Lentic ecosystem usually is usually still and is affected by seasonal changes as it contains smaller volume of water when compared to the Lotic ecosystem which has a high volume.
Seasonal changes such as summer or winter affects the Lentic system easily as the small volume of water gets heated up and frozen easily which encourages more evaporation and freezing respectively.

Explanation:
Essay 1 )
In many people's opinions mans impact on the environment is a big issue in our life which is easily neglected, as humans are responsible for a staggering amount of damage on the earth. Nature manages its own components.
Since the outbreak of technology and industrialisation humans have greatly had a negative impact on the environment, such as; air pollution, habitat destruction, water pollution, the burning of rainforests and land pollution. In this essay I intend to give facts and discuss the effects and causes on these topics and discuss the solutions being carried out to improve the conditions.
Air pollution effects people in areas of emission sources, such as, power plants, local industry and major roads. Humans contribute to pollution by the use of machinery in industry causing pollution to the environment. More effects of air pollution on the environment involve using diesel fuel for vehicles and coal for power along with the lack of emission controls for vehicles and industry.
Another cause of air pollution is the greenhouse gas CO2, this gas warms the earth through living things as they emit CO2 when breathing which contributes to humans also, as we add to this statistic through breathing also. CO2 is usually thought to be involved with cars, aeroplanes and power plants, in the past 150 years , CO2 has been polluting our atmosphere through the sources mentioned, this is the highest CO2 emissions recorded for a long time. More causes of air pollution is methane gas which comes from swamps which are contributed to man through flooding. Cfc's are another major cause of air pollution by man through the use of fridges and deodorants (aerosols) which harms the earth's ozone layer.
Essay 2 )
In order to meet the basic needs of increases population, the present society has under taken a series of steps like rapid industrialization, unplanned urbanisation, deforestation, overexploitation of natural sources, etc.The outcomes of the above human activities have contributed significantly to the degradation of environment around us.
Some important impacts of human activities on environment are outlined below:
1. Deforestation:
In order to provide timber and farm land to increased population, large number of forest trees are cut and forest area is converting to farm lands. The rate of deforestation is so faster that around 1.5 million hectare of forest cover is lost every year is India alone. The process of deforestation results in decreasing rainfall, increasing global temperature, loss of top soil, modification of climatic conditions etc.
2. Industrialization:
Although the industrial activities of man provide basic need of the society, simultaneously the same release a lot of pollutants to the environment. The pollutants in environment cause loss of raw materials, health hazards, increase in death rate, damage to crop, making environment unfit for living organisms etc.
3. Loss of ecological balance:
The excessive use, misuse and mis-management of biosphere resources results in disturbance in ecosystem or ecological imbalance.
4. Air pollution:
The anthropogenic release of various air pollutants to the environment causes a number of dreaded phenomena like green house effect, ozone layer depletion, acid rain and smog formation etc.
5. Water pollution:
Human activities in respect of disposal of sewage wastes, solid wastes, municipal wastes, agricultural and industrial wastes cause the environment unfit for day to day use. Besides, polluted water spreads or leads to different diseases.
6. Increased consumption of natural resources:
Since the starting of industrial era, the natural resources are constantly utilised for the production of one or more products for the day to day use of society.
7. Production of waste:
Rapid industrialization and unplanned urbanization release a lot of toxic waste material either in solid or liquid or gaseous state which induces a number of serious environmental hazards.
8. Extinction of Wildlife:
Since forests are natural habitats of wild life (both plants and animals) deforestation leads to the extinction of valuable wild life and loss of biodiversity.
9. Habitual destruction:
The commercial and industrial activities associated with mining, construction of dams, fishing, agriculture etc. cause habitat destruction which is a pathway to pollution.
10. Noise pollution:
The man-made noise due to mechanized automobile, industries, trains, aero planes, social functions etc. causes noise pollution which has impact on both biotic and a biotic components of environment.
These are the human impacts on environment

The cell membrane of an animal cell was damaged, preventing the cell from performing one of its functions. Which cell function would be lost, and how would this loss affect the cell?
Answer:
ok so
Explanation:
If the cell membrane of an animal cell is damaged, it would lose the ability to take in nutrients and excrete wastes. This would hinder the cell's capacity to create necessary materials and maintain proper functioning. Thus, the correct option is (b).
The correct response is option (b). The transport of chemicals into and out of the cell is regulated by the cell membrane, which acts as a selectively permeable barrier. Essential cell processes like food intake and waste elimination would be impeded if the membrane were to get disrupted.
This would impede the cell's capacity to produce required components through nutrient-dependent processes like metabolism. There would be a significant negative impact on the cell's general health and function, which could result in cellular malfunction, slowed growth, and ultimately cellular death.
