Explanation:

Nucleotides are the monomers of DNA. They consist of five-carbon sugar deoxyribose, a phosphate group and a nitrogenous base attached to the sugar. Nucleotides including adenine A thymine T guanine G and cytosine C  are available.

DNA monomers or nucleotides can bind phosphates and sugars on the outside and nitrogenous bases on the inside where they can bind to other nitrogenous bases to form a ladder. DNA is a polymer. The monomeric units of DNA are nucleotides and the polymers are known as polynucleotides.

Monomers are small mostly organic molecules that can combine with other similar molecules to form very large molecules or polymers. All monomers have the ability to form chemical bonds with at least two other monomer molecules. The unique structure of DNA allows the molecule to replicate itself during cell division. When a cell prepares to divide, the DNA helix splits in the middle and becomes two single strands.

It is not accurate to call a virus that kills bacteria a "bacteria eater" as it does not technically eat bacteria but infects it. The virus that enters a cell replicates it's genome inside it causing the cell to be infected with it.

Bacteriophages, or simply phages, are viruses that infect and kill bacteria. Bacteriophage is a name that means "bacteria eater." Although theoretically speaking, viruses don't consume anything, they do kill the bacteria and other infected cells. They have been demonstrated to successfully combat and eradicate multi-drug resistant bacteria and are the most prevalent biological organisms in nature.

Virus particles infiltrate host cells. Once a viral particle penetrates a host cell, its nucleic acid component or it's genome disrupts the processes of the cell, essentially taking over the host cell's proteins and other components to produce new viral particles.

Assuming the radius of the cell is given as r, to calculate the volume and surface area of a cell, the formula below is used;

Cells are the basic structural and functional unit of life.

Cells are what all living organisms are made up of.

Organisms that are made up of only one cell are said to be unicellular whereas organisms that are composed of multiple cells are said to be multi-cellular.

To calculate the volume and surface area of a cell, it is assumed that the cell is a sphere. This is because most cells when placed in a liquid medium or suspension, they exert equal forces in all directions, which results in the cells assuming a spherical shape.

To measure the radius of the cell, the cell is placed in a suspension and then viewed through a microscope at a know magnification. The radius of the cell is then taken.

The radius of the cell obtained is then used to calculate the volume and surface area of the cell.

While bases take protons in processes, acids donate protons (H+). While bases have a pH of 7 or higher, acids have a pH of 7.

While bases take protons in processes, acids donate protons (H+). While bases have a pH of 7 or higher, acids have a pH of 7. Acids release H+ ions while bases release -OH when they separate in water. While acids render litmus paper red, bases turn it blue.

1) In Experiment 1, the color of the solution changes from light (suggesting base) to dark when the acid is introduced (suggesting acid). As a result, adding the acid in this instance produced an ACIDIC solution.

2) In Experiment 2, the reverse is accurate. The hue stays light even after the addition of the acid (suggesting base). The outcome in this instance is BASIC as a result.

3) When the acid is given to the base to buffer it, this is Experiment 2. As you recall, a buffer solution is one that doesn't alter in pH when an acid or basic is introduced. We may infer that the addition of the acid in Experiment 2 was made to produce a buffer solution because it was done so the pH didn't fluctuate as much as it did in Experiment 1.

The particles are compressed, closer together, and collide more frequently, energy is transferred during collisions.

Because of the tighter spacing between particles, particles move quickly in all directions but collide more frequently than in gases. Because the particles gain kinetic energy as the temperature rises, they move faster, increasing the likelihood of collisions and diffusion.

A solid is made up of very closely spaced-apart particles. Each particle is firmly anchored in situ and is limited to stationary vibration. Many solids contain particles that arrange themselves into crystals in a predictable, repeating pattern.

The molecules will travel quicker and are more likely to collide with one another if there is more energy available to them. Higher temperatures should result in more molecule-to-molecule collisions and more frequent chemical reactions.

Answer: Urban sprawls are unsustainable.

Explanation: Urban environmental sustainability encourages the revitalization and transition of urban areas and cities to improve liveability, promote innovation and reduce environmental impacts while maximizing economic and social co-benefits. Urban systems are inherently complex. Urban sprawl has significant environmental, economic and social consequences. It leads to higher emissions from road transport and loss of open space and environmental amenities.

Answer: No

Explanation:

Urban sprawl is the expansion that refers to a complex pattern of land use, transportation, and social and economic development usually as a direct effect of population growth on a national level. Urban sprawl is not sustainable for the environment because it creates an increase in water and car usage increasing air pollution, and creates a loss of agriculture capacity of the land. This increase in air pollution and loss of agriculture and woodlands leaves no plants able to create oxygen to sustain a thriving ecosystem. While some may argue that Urban sprawl helps create a better economy, better employment, and better living conditions, in terms of Biology, Urban sprawl is a leading cause of the destruction of our ecosystems.
