Answer;

shortly:-The main differences between prokaryotic and eukaryotic cells are the presence of a nucleus, the size and complexity of the ribosomes, how the cells reproduce and the presence of a cell wall. Ribosomes: In eukaryotic cells, the ribosomes are bigger, more complex and bound by a membrane

but you need more explanation:-

Eukaryotic organisms are made out of cells that possess membrane-bound organelles and a membrane-bound nucleus. The genetic material of eukaryotic organisms is found within the nucleus of the cell and chromosomes are how the DNA is organized within the nucleus. Eukaryotic cells comprise both single-celled and multicellular forms of life. Eukaryotes compose the bodies of all protists, fungi, plants, and animals.

Eukaryotic cells display an impressive amount of diversity, and they are capable of being many different shapes and sizes. The structure of a eukaryotic cell is tied closely to its function. For example, the epithelial cells that make up the human body are usually divided into three different types: squamous, cuboidal, and columnar. Each of these different cell types has a different form that enables it to carry out its respective functionsEukaryotic cells may have the following parts:

   Cell wall (only plant cells)

   Plasma membrane

   Nucleolus

   Nucleus

   Chromosomes

   Vesicles

   Golgi apparatus

   Ribosomes

   Endoplasmic reticulum

   Cytoplasm (and cytoskeleton)

   Lysosomes

   Mitochondria

   Centrioles

   Chloroplasts (only plant cells)

Prokaryotic cells are almost always much smaller than eukaryotic cells. The size of a prokaryotic cell is usually around 1 µm, while the size of animal cells and plant cells are usually between 10 to 100 µm. Because eukaryotic cells are much larger than prokaryotic cells, they have evolved special methods of transporting substances around the cell that bacteria don’t have.

The distinction between eukaryotes and prokaryotes is based upon two theories regarding the role of cells in biology. Cell theory states that all living things are made out of cells, and biogenesis theory proposes that all living cells came from other existing cells, so cells cannot spontaneously arise from non-living things (abiogenesis). For cells to comprise all the life we see on Earth they must be able to organize proteins and other chemical compounds. Individual cells are capable of keeping chemical processes isolated and compartmentalized so one chemical process doesn’t interfere with another chemical process, which runs the risk of disrupting the delicate chemical balance of the cell and leading to cell death.

   “A cell is regarded as the true biological atom.” — George Henry Lewes

To keep the chemical processes within a cell isolated and organized, cell components stay enclosed within a membrane that serves as the barrier between the interior of the cell and the cell’s environment. The membrane of a cell is selectively permeable, meaning that the cell will allow some chemical compounds into the cell and not others. The membrane of the cell is made out of a phospholipid bilayer, two groups of lipids arrayed in layers and facing opposite directions. Smaller compounds can penetrate the phospholipid bilayer, but larger compounds must enter the cell using a pore in the cell membrane.

The cell membrane has various methods of regulating how chemicals move in and out of the cell. Diffusion refers to the tendency of molecules at high concentrations to distribute out to areas of lower concentration until the concentrations across the two areas equalize. Osmosis is similar to diffusion, but it refers to the movement of a solvent across a boundary instead of a solute. This helps to equalize a solute that can’t move through a boundary. Selective transport, the movement of molecules within the cell, is handled by both membrane pumps and membrane channels.

Explanation:

Answer:

this is true it neutralise easily

It is true that in the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.

DNA extraction is a method of separating DNA from cell membranes, proteins, and other cellular components using physical and/or chemical methods from a sample. In 1869, Friedrich Miescher isolated DNA for the first time.

The ability to extract DNA is critical for studying the genetic causes of disease and developing diagnostics and drugs.

It is also required for forensic science, genome sequencing, detecting bacteria and viruses in the environment, and determining paternity.

Because sodium (Na+) neutralizes the negative charge of DNA, cells are mixed with sodium chloride (i.e. NaCl) during the DNA isolation process. It makes homogenization easier.

When a stone is dropped into water, it disturbs the surface of the water, and this is called "ripples" or "waves".

The disturbance caused by the stone creates waves that travel away from the point where the stone entered the water. These waves can be seen as ripples spreading outwards from the point of impact. The size and shape of the ripples depend on various factors, such as the size and weight of the stone and the depth and temperature of the water.

As the waves move away from the point of impact, they carry energy with them. This energy is transferred to the water molecules as the waves pass by, causing them to move up and down. The movement of the water molecules creates a wave pattern that can be seen on the surface of the water.

The ripple effect caused by a stone dropped into water is a simple example of how energy is transferred through a medium. It is also a common visual metaphor used to describe the way in which small actions can have large and far-reaching consequences, as the ripples caused by the stone continue to spread outwards in all directions, affecting everything in their path.

Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

The correct option is 1) (GAAG) repeated twice.

Explanation:

(GAAG) repeated twice is structurally the smallest DNA fragment as compared to the other fragments. Hence, it will be the fastest and farthest to move in the gel electrophoresis with less amount of cluster as its only repeated twice.

What is Gel electrophoresis?

In a lab setting, gel electrophoresis is a technique used to divide mixtures of DNA, RNA, or proteins based on their molecular sizes. An electrical field pushes the molecules to be separated through a gel that has tiny holes during gel electrophoresis. A speed that is inversely proportional to a molecule's length is how quickly it moves through the pores in the gel. Because of this, a smaller DNA molecule will go through the gel further than a larger one.

Answer:

Populations, species, communities, and ecosystems are all related components of the natural world. A population is a group of individuals of the same species living in the same area. Multiple populations of different species living in the same area form a community. An ecosystem is a community of living organisms and their physical and chemical environment, all functioning together as a unit.

Therefore, populations make up species, multiple species make up a community, and communities, along with their physical and chemical environment, make up an ecosystem. All of these components are interconnected and interdependent, as the interactions and relationships between individuals and species within a community affect the overall functioning and health of the ecosystem. For example, changes in population size or behavior of one species can have cascading effects on other species and the physical environment within an ecosystem.

The greatest decline on record in the Moose population occurred in 1996-1997, and the limiting factor that probably caused the decline was density-dependent, specifically winter tick infestation.

winter tick infestation is a classic example of a density-dependent factor that can cause significant harm to Moose populations. A high density of moose populations can lead to a higher probability of infestation and greater negative impacts on individual moose health.

In the case of the Moose population decline in 1996-1997, the winter tick infestation was likely the main limiting factor responsible for the decline. The tick population can increase rapidly when moose densities are high, leading to a higher probability of infestation and greater negative impacts on individual moose health. This is further supported by the fact that the Moose population in other regions, with lower densities, did not experience the same level of decline.

Therefore, the limiting factor that caused the decline in Moose population in 1996-1997 was likely density-dependent, specifically the winter tick infestation.

Answer: the theory of evolution states that all living things we can identify descend from the Last Universal Common Ancestor. It is not that the translation process between mRNA and amino acids is universal, but that the underlying genetic code relating DNA nucleotide triplets (codons) to amino acids is the same for almost all living things.

Explanation: The genetic code ‘tells’ mRNA which the sequence of amino acids in a protein and when to stop adding amino acids. The DNA . triplets, called codons, code for 20 amino acids and a STOP signal. The code is identical in almost all cases, but there are variation, mostly found in mitochondrial DNA. But even when these variants exist, most of the code is the same as in other living organisms. For example the codon AGG normally codes for the amino acid serine but in arthropod mitochondria it codes for lysine. These very few and minor changes tend to confirm the single ancestry of the code and how well it has been conserved through billions of replications

Explanation:

The nutrient which provide more energy is C. Lipids

Among the given options, lipids provide the most energy per unit mass. Lipids, also known as fats, are a concentrated source of energy in the diet. When metabolized, lipids yield approximately 9 kilocalories (kcal) of energy per gram.

Carbohydrates, including sugars and starches, provide approximately 4 kcal of energy per gram. They are a readily available source of energy for the body, particularly for short-term energy needs. Proteins also provide approximately 4 kcal of energy per gram. However, their primary role is not as an energy source but rather as the building blocks for tissues, enzymes, and other important molecules in the body.

Vitamins, on the other hand, do not provide significant energy. They are essential for various biochemical processes in the body but do not contribute directly to energy production.

It is important to note that while lipids provide the most energy per gram, the overall balance and variety of nutrients in a diet are crucial for maintaining optimal health. Nutrient needs vary based on individual factors, such as age, sex, activity level, and overall health goals. Therefore, Option C is correct.
