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.

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

Which of the following sequences best illustrates primary succession in a forest?
A. forest fire – pioneer species – willow - hardwood
B. bulldozed trees – shrubby weeds – cottonwoods – pine trees
C. exposed rock – lichens – weeds – shrubs – hardwoods – stable forest
D. flood – mosses – ground cover - shrubs
Answer:
C.
Explanation:
Primary succession is where it is a new area, not one where the area was simply made uninhabitable which gets rid of A, and B. C goes into more detail as to what actually happens as lichens consume the rocks while weeds come in afterwards due to the soil being formed since the lichen has broken down the rocks. Shrubs follow because enough soil has formed. followed by hardwoods and trees cause the roots of previous plants have formed enough soil for larger organisms and eventually a forest
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.

Have you ever wondered how we can grow from one cell to millions? How do you think this happens?
Answer:
If you think about it, the fact that a single cell can grow into an adult with trillions of cells is pretty awesome. ... It's a process called the cell cycle. Entire organisms grow, and develop by going through the cell cycle again and again. The cell cycle also helps us maintain a healthy body.
From a single cell to multiple cellular organism is formed by different complex mechanism like by cell division which involves a central dogma of life includes three process such as replication, transcription and translation and fourth one is reverse transcription.
what is central dogma ?The ‘Central Dogma’ is the flow of transfer of genetic information, from DNA to RNA to make a functional product, a protein, was first proposed in 1958 by Francis Crick.
DNA contains the genetic information needed to make proteins, and RNA act as a messenger that carries this information to the ribosomes where the information is translated into protein.
The process by which the DNA information converted into protein called gene expression which can occur in two stages like transcription and translation.
The central dogma occurs most frequently in our cells in three stages such as DNA replication that refers to make new DNA from pre existing DNA, transcription to make RNA from DNA and translation from RNA to protein.
Reverse transcription is defined as the transfer of information from RNA to make new DNA in a reverse manner which occur mainly in retroviruses, such as HIV.

How cells make proteins quick check. Select the statement that is true
Answer:
In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.
In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.
What are proteins?The protein molecules that the genes in DNA encode are the "workhorses" of the cell, performing all the tasks required for life. Proteins include, for instance, DNA polymerases and other enzymes that produce copies of DNA during cell division, as well as enzymes that metabolize nutrients and synthesize new cellular components.
The simplest definition of gene expression is the production of the gene's corresponding protein, and this complex procedure involves two main phases.
Transcription is the process by which the data in DNA is converted into a messenger RNA (mRNA) molecule in the initial phase. A pre-mRNA molecule is formed during transcription by an enzyme called RNA polymerase II using the DNA of a gene as a template for complementary base-pairing.
Therefore, In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.
