Why do scientists often use bacteria to produce medicines?

Answers

scientists have ways to ensure that the bacteria make the proteins in large amounts. For these reasons, bacteria can function as 'protein factories', producing medically important proteins and others.

Scientists often use bacteria to produce medicines because of their easy use, genetic manipulability, and genetic ability to produce medicine.

What are the characteristics of bacteria?

Scientists often use bacteria to produce medicines because bacteria grow quickly and can be cultured in large quantities. This makes them a cost-effective option for production of large amounts of medicine.

Bacteria also have a simple genetic makeup that is easy to understand that allow scientists to easily produce proteins. Some bacteria have the ability to produce natural compounds containing medicinal properties, such as Streptomyces produces several antibiotics that are used in medicines.

Bacteria can also be genetically engineered to produce new compounds that can be used as new medicines. Bacteria are highly versatile for production of wide range of medicines.

Therefore, bacteria are used for producing medicines because of easy use, genetic manipulability, and genetic ability to produce medicine.

In a deciduous forest of Maine, there are 300 Falcons living in a certain region at the beginning of the year. Scientists have determined that these Falcons demonstrate exponential growth and that their per capita growth rate is 0.067. What will the population of Falcons be in 5 years?

Answers

Answer:

419 Falcons

Explanation:

P= Poe^rt

P= population at time t = ?

Po = initial population = 300

r= growth rate = 0.067

t = time taken = 5 years

P = 300e^(0.067 * 5)

in recent years much of califorinia has had drought conditions much of our food comes from califorinia and there are many growing cities in that state what do you think has happened to the ground water supply as droughts have occured there explain how a diversion system could be useful califorinia including the parts of such a system

Answers

Answer:

The level of ground water decreases.

Explanation:

Due to drought condition, the level of ground water decreases because of pumping of water for the irrigation purpose. Huge amount of water is required to irrigate a large area of California and in the drought conditions ground water is the only solution for this problem. The diversion system will be useful California by diverging river into these drought affected areas in order to fulfill the need of water for growing crops so we can conclude that this diversion system helps to fulfill the necessity of water during drought situation.

What is the main difference between the intertidal zone and the neritic zone?

the amount of exposure to sunlight
the amount of salt in the water
the amount of time covered by water
the presence of plants and animals

Answers

Answer:

intertidal zone is the area of shore between the high tide and low tide lines whereas neritic zone is the area of the ocean from the low tide line out to the continental shelf.

The main difference between the intertidal zone and the neritic zone is the amount of time covered by water.

What is intertidal zone and the neritic zone?

The intertidal zone is the area of the shoreline that is regularly exposed to air at low tide and submerged at high tide. This area is characterized by its exposure to fluctuations in water level, temperature, and salinity, and is home to a diverse range of organisms that have adapted to these conditions.

The neritic zone, on the other hand, is the shallow ocean water over the continental shelf, extending from the low tide mark to a depth of about 200 meters. Unlike the intertidal zone, the neritic zone is always covered by water and is characterized by relatively stable physical conditions, including a relatively constant temperature and salinity.

While the amount of exposure to sunlight can vary in both the intertidal and neritic zones, the main difference between these two habitats is the amount of time covered by water and the resulting stability of environmental conditions.

According to the World Population Growth graph, which best describes the human population growth after the Industrial Revolution?

Slow growth

Exponential growth

Negative growth

Zero growth

Answers

Answer:

negative

Explanation:

According to the World Population Growth graph, the human population growth after the Industrial revolution will be exponential growth. Thus, the correct option will be B.

What is the Exponential growth?

Population growth can be defined as the annual increase in the population size of a species. Population growth is the difference between the total births less the total deaths and the difference between immigrants less the emigrants, in a given country, territory or a geographic area at a given year.

Exponential growth of a population is a function which shows an increase within a population that occurs at the same rate throughout the time period. When different populations experience doubling or tripling in numbers, then we can assume the data increases exponentially through the time. The opposite of exponential growth is exponential decay of the population, where the data shrinks rather than it grows.

Therefore, the correct option will be B.

Eukaryotic cell

Explanation:

The cell of living organisms have been classified as either eukaryotic or prokaryotic depending on whether or not it contains a NUCLEUS. A prokaryotic cell is a cell that does not contain a membrane-bound nucleus to house its genetic material e.g bacteria, archaebacteria etc.

On the contrary, eukaryotic cells possess a membrane-bound nucleus that houses their genetic material e.g fungi, animals, plants etc. Based on the above explanation, an EUKARYOTIC type of cell produces a nucleus.
