is urban sprawl sustainable ? (5 sentences )
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.
Explanation please! How would you calculate the volume and surface area of a cell?
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;
Surface area of the cell = 4 * π * r²Volume of the cell = ⁴/₃ * π * r³What are cells?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.
What is the difference between Acid and Base?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.

Simplify meiosis into its basic events
Nucleus division and cytokinesis take place twice, first in meiosis I and again in meiosis II.
MeiosisIn sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent). The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.To learn more about Meiosis refer:

A strategy for fighting bacterial infections uses viruses. Viruses that infect bacteria are called bacteriophages. Phage comes from the Greek word for “eater.” Explain why it is not accurate to call a virus that kills bacteria a “bacteria eater." What happens when a virus attacks a cell?
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.

a phenotype that varies across a continuous spectrum
a phenotype that, when observed in a mother, will certainly be observed in her son
A phenotype where only a single allele is sufficient for expression.
Polygenic traits are traits that are influenced by more than one gene such as height or skin color. Because multiple genes are involved, polygenic traits do not follow Mendelian inheritance patterns. A pleiotropic gene is a single gene that controls multiple traits. While studying the genetics of peas.
Gregor Mendel made an interesting observation regarding the colors of different parts of plants. Pleiotropy occurs when a gene affects two or more seemingly unrelated phenotypic traits.
