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

Balloon size increases as the sugar increases in the solution.

As the yeast feeds on the sugar or sugar solution which produces carbon dioxide gas. Due to presence of balloon, there is no place to go so gas slowly fills the balloon. Carbon dioxide gas produces from yeast fills thousands of balloon.

That solution which have high amount of sugar in it will leads to higher concentration of carbondioxide gas in the balloon so we can conclude that balloon size increases as the sugar solution increases.

Igneous rocks are classified on the basis of their composition and their texture. Magma, and the igneous rock it becomes, has a range of chemical compositions. For example, basalt is a mafic lava flow rock which originates from melting of the upper mantle.

Explanation:

Answer:

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.

If the number of eagles in the ecosystem increases,the carrying capacity of the fish population will go down.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

We feel the inside of the elbow as we lift a book. We should feel a strong cord. This cord is known as Oblique cord.

The oblique cord is a ligament which is present between the ulnar and radius bones in the forearm region near the elbow. Oblique cord takes the form of a small, flattened band, which is extending downward and lateralward, from the lateral side of the ulnar bone tuberosity at the base of the coronoid process to the radius of a little below the radial tuberosity. The fibers in this cord runs in the opposite direction to those of the Interosseous membrane of the forearm region of the hand.

The oblique cord may simply be defined as an additional tie which is between the radius and ulna of the hand which is aiding other soft tissue structures such as the annular ligament and interosseous membrane. Additionally, the oblique cord may also prevent the anterior shearing of the proximal radius under the extreme compressive loads.

If human red blood cells are placed in solutions of different osmolarity, then the 300 osmoles/L solution will be the isotonic solution.

An isotonic solution to the red blood cell would be a solution that has the same solute concentration as the red blood cell.

Isotonic solutions are different from hypotonic and hypertonic solutions. Hypotonic solutions would have lower solute concentrations than the red blood cell while hypertonic solutions would have higher concentrations than the red blood cells.

The red blood cells of humans have a certain amount of solute in their cell sap which has been approximate to be between 286 and 295 osmoles/L. Thus, the only solution close to being an isotonic solution to these cells would be the 300 osmoles/L solution.

More about osmolarity can be found here: https://brainly.com/question/8144230

Answer: 300 osmoles/ L solution

Explanation:

The 300 osmoles/ L solution is the solution closest to the osmolarity of a normal human red blood cell.

This means that the 300 osmoles/ L solution is the isotonic solution. If added to human red blood cells, the shape and size of the red blood cells with remain as they were, unchanged (unlike if a hypotonic/ hypertonic solution was added.)

Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing. They do not react because they have no electronegativity and no "extra" electrons

Explanation:

Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing.

Carbon atomic number is 6. Its electronic configuration is 1s2 2s2 2p2. As you can see from the electronic configuration the inner shell has 2 electrons and the outer shell with principal quantum number 2 has 4 electrons.

An atom is made up of electrons, protons and neutrons. Both protons and neutrons are located in the nucleus of the atom, while electrons are in the shell/s. The shell of an atom is the orbit on which the electrons revolve around the nucleus. The number of shells in an atom extends from the first, n =1, to infinity, n = ∞, depending on the number of electrons in the given atom.

The first shell, n =1, is the ground state and can only contain a maximum of 2 electrons. The inner shell contains two electrons and the outer shell contains four electrons.

Therefore, Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing.
