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

How does your diet (the different types of foods you eat) affect the water cycle? what types of foods use the least amount of water, and what types of food use the most water?
Answers
Answer: Your diet can probably effect. More animals may consume more water than others. Or more plants drink more water than others. by eliminating these animals, there is more water left. Some plants that use the last water is the Sago Palm, Snake plant, Orchids, Spider plant, and plenty of the plant species who are adapted to dry climats. The plants that consume the most water are Ferns, Lilys, Daylilies, Indian grass, Cattails, Iris, and Elephant ears. The animals that consume the most water is probably the biggest animals like elephants and cows, who according to my search can consume up to 100 gallons of water a day durring hot summer months. So, the least water, the less it will rain, the less clouds there would be, and the easier it would be for the land to dry out.

11. A flower produces a seed. Explain why this is an example of sexual reproduction
Answers
Answer:
itrequires genetic material (DNA) from two parents. The parent plants have male and female sex cells, called gametes. ... Seeds produced through fertilization contain genetic material from both parents.
The production of a seed by a flower is an example of sexual reproduction because it involves the fusion of male and female gametes (pollen and ovules) to form a genetically diverse offspring.
Sexual reproduction is a type of reproductive process that involves the combination of genetic material from two parent organisms, resulting in the formation of genetically diverse offspring. In the case of a flower producing a seed, sexual reproduction occurs through a series of specialized reproductive structures and processes.
Male Gamete Production (Pollen): Flowers produce male gametes, or pollen, in structures called anthers. Pollen contains the male reproductive cells necessary for fertilization. When pollen is mature, it is released from the anthers.
Female Gamete Production (Ovules): Flowers also produce female gametes, or ovules, within the ovary. Each ovule contains an egg cell, which is the female reproductive cell. The ovary is located at the base of the flower.
Pollination: Pollination is the process by which pollen from the male reproductive structures (anthers) is transferred to the female reproductive structures (stigma) of the same or a different flower. This can occur through wind, water, insects, birds, or other means.
Fertilization: Once pollen lands on the stigma of a compatible flower, it forms a pollen tube that grows down into the ovary. This tube delivers the male gametes to the ovules, where fertilization occurs. Fertilization is the fusion of a male gamete with a female gamete to form a zygote, which develops into an embryo within the seed.
Seed Formation: After fertilization, the ovule develops into a seed, which contains the embryo, endosperm, and protective seed coat. The embryo carries genetic information from both parent plants, resulting in genetic diversity.
The combination of genetic material from male and female parent plants results in offspring with unique genetic characteristics. This genetic diversity is advantageous for the survival and adaptation of species to changing environments. Therefore, the production of a seed by a flower is a prime example of sexual reproduction, involving the fusion of gametes to create genetically diverse offspring with traits inherited from both parents.

A de-shelled egg is placed in tap water. The egg grows in size.
What is the best explanation for this change in size?
Ions in the water moved into the cell through diffusion because there were more ions outside the cell than inside the cell.
Water moved into the cell by osmosis because the solute concentration was higher inside the cell than outside the cell.
Water moved out of the cell by osmosis because the solute concentration was higher outside the cell than inside the cell.
Water moved into the cell by diffusion because there is more water inside the cell than outside the cell.
Answers
The best explanation for the change in the egg's size is that Water moved into the cell by osmosis because the solute concentration was higher inside the cell than outside the cell. Option B.
--------------------------------------------
When talking about solutions, we can classify them as follows,
Hypertonic ⇒ A hypertonic solution has a higher concentration of solute than the cell. This means that in the cell interior, the solute concentration is lower than in the solution itself. Isotonic ⇒ The solute concentration is the same inside the cell and outside. Hypotonic ⇒ A hypotonic solution has a lower concentration of solute than the cell. This means that in the cell interior, the solute concentration is higher than in the solution itself.
Water is considered to be a hypotonic solution.
When a cell is in a hypotonic solution, through osmosis, water moves toward the cell.
Note: In this example, the egg is the cell.
Osmosis is the phenomenon that occurs when two dilutions of different concentrations -in this example, the interior of the cell and the solution- are separated by a semipermeable membrane.
The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.
Water tends to go from the hypotonic solution to the cell interior and keeps doing so until concentrations are equal in the cell interior and exterior.
As water enters the cell, the cell begins to enlarge and becomes bigger-sized. And because cells can not limit the amount of water moving in, it keeps swelling until the membrane can not stretch anymore, and lysis occurs. It bursts.
What we need to consider is
When a cell with a semipermeable membrane is placed in a hypotonic solution, water enters the cell. When a cell with a semipermeable membrane is placed in an isotonic solution, there is no water movement. When a cell with a semipermeable membrane is placed in a hypertonic solution, water gets out of the cell.So, the best explanation for the change in the egg's size is Water moved into the cell by osmosis because the solute concentration was higher inside the cell than outside the cell. Option B.
