Explain the processes of diffusion and osmosis and their roles within a cell? plss help with a thorough expliation
Answers
Answer:
Diffusion:
Substances, such as water, ions, and molecules needed for cellular processes, can enter and leave cells by a passive process such as diffusion.Diffusion is a type of substance movement that requires no energy to be expended for the substance to move. Simple diffusion occurs when there is no obstacle to the substance so it can diffuse freely.
Osmosis:
Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute (lower concentration of solvent).There are three types of solutions that's determine osmosis-
1) hypotonic solution: in this case the solvent is less and the solution is more(dilute solution).More water is there outside the cell than inside the ell, so the water moves into the cell which causes the cell to swell up
2)hypertonic solution: in this case there is more solute than solvent(concentrated). More water is there inside the cell than outside the cell, so more water will leave the cell than it enters as a result the cell will shrink.
3) Isotonic solution: the amount of water inside the cell is equal to water outside the cell as a result the cell will neither shrink not swell.
Examples of diffusion:
Oxygen and carbon dioxide, dissolved in water, are exchanged by diffusion in the lungs: oxygen moves down a concentration gradient from the air in the alveoli to the blood. carbon dioxide moves down a concentration gradient from the blood to the air in the alveoli.
Examples of osmosis:
Osmosis occurs to recover water from waste material. Kidney dialysis is an example of osmosis. In this process, the dialyzer removes waste products from a patient's blood through a dialyzing membrane(acts as a semi-permeable membrane) and passes them into the dialysis solution tank.

Which type of plate boundary occurs where two plates collide?
Answers
Explanation:
The Earth’s lithosphere, which includes the crust and upper mantle, is made up of a series of pieces, or tectonic plates, that move slowly over time.
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench. A chain of volcanoes often forms parallel to convergent plate boundaries and powerful earthquakes are common along these boundaries.
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Two plates sliding past each other forms a transform plate boundary. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon. Earthquakes are common along these faults. In contrast to convergent and divergent boundaries, crust is cracked and broken at transform margins, but is not created or destroyed.

Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.

A. Fishing can never be done responsibly.
B. Fishing never accidentally kills fish or marine animals.
C. Overfishing will affect only the species of fish that is being caught.
D. Overfishing will cause the deaths of many marine species that are not directly being fished.

Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

In 4 or more complete sentences, describe the process of protein synthesis and explain how transcription and translation creates protein
Answers
Protein synthesis occurs in the cell and is divided into 2 stages, namely transcription and translation. The process of transcription occurs in the cell nucleus by copying the genetic code in DNA and forming mRNA strands which are duplicates of DNA.
The RNA strands that are formed will come out of the cell nucleus and then undergo a translation process that occurs in the cytoplasm. With the help of ribosomes, the amino acids will line up according to the sequence of the genetic code in the mRNA to form polypeptide chains that make up the protein structure.
What is protein synthesis?
Protein synthesis is the formation of proteins in the human body and occurs in the smallest units, namely cells. Protein synthesis is divided into 2 stages, in the following order:
1. Transcription
Transcription is the process of copying the genetic code or DNA that occurs in the cell nucleus or nucleus. The process of copying the genetic code is carried out by unbinding the DNA with the help of RNA polymerase, then forming a copy of the genetic code that is complementary to the sequence of hydrogen bases in the DNA. The process of transcription produces a strand of genetic code called mRNA or RNAd.2. Translation
Translation is the process of translating the genetic code contained in the mRNA and occurs in the cytoplasm. With the help of the ribosome, the mRNA will be translated and the amino acids will move towards the ribosome. Amino acids will form a sequence that is complementary to the mRNA so that a polypeptide strand that makes up the protein molecule is formed.Learn more about Protein synthesis at https://brainly.com/question/15404950
#SPJ1
1. Transcription:
Transcription is the first step in protein synthesis and takes place in the nucleus of eukaryotic cells or in the cytoplasm of prokaryotic cells. It involves the conversion of genetic information from DNA into a complementary RNA molecule. Here's how it works:
a. DNA unwinding: An enzyme called RNA polymerase binds to a specific region of the DNA molecule known as the promoter. The DNA molecule unwinds at this site.
b. Complementary RNA synthesis: RNA polymerase reads the DNA template strand and synthesizes a complementary RNA molecule, using adenine (A), cytosine (C), guanine (G), and uracil (U) as the RNA bases, instead of thymine (T). This newly formed RNA molecule is called messenger RNA (mRNA).
2. Translation:
Translation is the second step in protein synthesis and occurs in the cytoplasm, specifically at the ribosomes. It involves the conversion of the mRNA molecule into a functional protein. Here's how it works:
a. Initiation: The ribosome attaches to the mRNA molecule at a specific start codon (usually AUG), signaling the beginning of translation.
b. Elongation: Transfer RNA (tRNA) molecules bring amino acids to the ribosome, guided by the mRNA codons. These tRNA molecules have anticodons that complement the mRNA codons.
c. Peptide bond formation: As the ribosome moves along the mRNA molecule, it catalyzes the formation of peptide bonds between the amino acids carried by tRNA molecules. This forms a growing polypeptide chain.
d. Termination: Translation continues until a stop codon (UAA, UAG, or UGA) is encountered on the mRNA. At this point, a release factor binds to the ribosome, leading to the release of the completed polypeptide chain.
In summary, protein synthesis begins with transcription, where DNA is transcribed into mRNA. Then, during translation, the mRNA is decoded by ribosomes, and amino acids are linked together to form a polypeptide chain, which eventually folds into a functional protein. This intricate process ensures that the genetic information encoded in DNA is faithfully converted into the proteins that carry out essential functions within cells and organisms.
Look at the diagram of the rock cycle below.
Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.

D.

Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.
