Using mass transportation can reduce pollution

The movement of people within metropolitan areas utilizing mass transit, often known as mass transportation or public transportation, includes buses and trains.

Mass transportation allows for movement, can influence how land is used and how development takes place, help to create jobs and promote economic expansion, and support governmental regulations pertaining to energy use, air quality, and carbon emissions.

The ability for trade, commerce, and communication that create civilization is the significance of mass transportation. Good planning controls traffic flows and makes it possible for people to go from one place to another quietly and steadily.

The probability that neither of them is a heavy smoker is 0.53 or 53%

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.

In this case:

Probability that selected one is heavy smoker is:

p=270/1000=0.27

Number of individuals selected  is 2 and We know that:

P(X=x)=nc_x(1-p)^{n-x}(p)^x

We need to prove that X=0:

P(X=0)=nc_0(1-0.27)^{2-0}(0.27)^0

P=0.5329

The trophic web is the interaction between different organisms in which there is energy transference. In the attached example, we consider plants, beetle, rabbit, frog, eagle, fox, mountainlion, and fungi.

The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.

The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at each level feed on the preceding one and become food for the next one.

• The first link corresponds to a producer organism -autotroph-.

• The following links are the consumers -heterotrophs- ⇒ herbivores and carnivores.

• The last links are the decomposers that degrade organic matter from dead organisms.

Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.

Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Example.

To make the trophic web, first, we need to have at least four links.

So first, let us list the organisms we are working with, and then define the position of each of the organisms on the web.

Producer → this is the autotroph organism that takes energy from the sun or any other inorganic source → An example of this is any plant.

Consumers → heterotroph

⇒ Herbivores → These are the animals that feed on any part of the plants → These are the beetle and the rabbit

⇒ Carnivores → These are the animals that feed on herbivores → These are the frog, the fox, the eagle, and the mountain lion

Decomposer → detritivorous organisms that take energy from dead matter → Fungi

Trophic web,

Plant >> Beetle and Rabbit

Rabbit >> Eagle

Beetle >> Frog

Frog and rabbit >> Fox

Fox and Eagle >> Mountain lion

Plants, beetle, Rabbit, Fox, Eagle, Mountain lion >> Fungi

The difference is due to the dose and the purpose of the radiation.

Radiology is the application of radiation in medicine to diagnose or to treat diseases.

Diagnosis of diseases is aimed at identifying the cause of a disease.

Treatment of diseases is aimed at curative purposes.

Therefore, one patient will have a radiologic procedure to diagnose a condition because the cause of the disease is yet to be ascertained, while another has radiation treatment to destroy a tumor because radiation can destroy tumors at a particular dose.

In conclusion, radiation can be use to diagnose or treat diseases based on the dose.

Answer: Individuals with mental illness are often mistreated in jail because mental illness is misunderstood.

Explanation:

There are specialized hospitals made for the treatment of mental illnesses just like there are for physical illnesses. So, people with mental illnesses should be moved to specialized hospitals as they also need to be treated.

Psychiatric hospitals are made to provide the proper treatment and care required by the people suffering from various forms of mental illnesses. These hospitals are equipped with doctors with specializations in psychiatric health, also called psychiatrists and other staff who are trained to care for the patients.

When people suffering from a mental health issue commit a crime or break the law, they should not be kept in prison as neither they nor other inmates would be safe in such a condition.

If a person suffering from a mental illness needs to be imprisoned, they should be relocated to a specialized psychiatric hospital as they would require proper treatment for their issues and would not face challenges due to other patients and staff at the hospital as they would if they were kept in jail.

Therefore, the correct option is C.

Answer:

55/8 as a mixed fraction

Explanation:

4 2/8 - 2 5/8 = ?

Four and two-eighths can be represented as a mixed number by multiplying (4x8+2)/8 = 34/8

Two and five-eighths can be represented as a mixed number by multiplying (2x8+5)/8 = 21/8

Then, these two values can be easily added. 34+21 = 55/8

You can plot this on a number line by also representing these mixed fractions as a decimal, and then adding them - you can draw lines to represent the addition process.

Since the number line already represents a tick on every eighth (which is the fraction you would primarily be using), this will make it earlier.

The Indian Plate and Eurasian Plate colliding caused the formation of the Himalayan Mountains and Tibetan Plateau.

When India and Tibet collided, the relatively light sedimentary and metamorphic rock that makes up the Indian subcontinent pushed against Tibet, driving it upwards, and creating a gigantic mountain fold instead of descending with the plate.

Where continental plates clash, mountains form. Each plate will not sag below the other because they are the same thickness and weight.

Instead, they give way and fold until the rocks are forced to take the shape of a mountain range. Mountains keep rising in height as the plates continue to collide.

As a result of the Indian Plate and Eurasian Plate colliding, the Himalayan Mountains and Tibetan Plateau were created.

The host cell may lyse or may continue to divide and replicate both itself and the prophage.

Lytic cycle:

The infecting phage kills the host cell at the end of the lytic cycle, also known as a virulent infection, to create a large number of its own offspring. The phage genome immediately produces early proteins that degrade the host DNA after being injected into the host cell, enabling the phage to take over the cellular machinery.

The remaining proteins needed to construct fresh phage particles are subsequently synthesized by the phage using the host cell. The new genetic material is packed into the head while new daughter phage particles are built, and the heads and sheaths are created independently. In the course of this process, phage enzymes gradually weaken the host cells, which eventually burst, dispersing 100–200 additional phage progeny into the environment.

Lysogenic cycle:

The lysogenic cycle, also known as temperate or non-virulent infection, uses the host cell as a haven where it can survive in a latent state. It does not harm the host cell. After the phage DNA is injected into the host cell, it uses integrases encoded by the phage to integrate into the host genome, at which point it becomes known as a prophage.

The host cell divides for the duration that it is there and does not create the proteins necessary to make progeny, at which point the prophage genome is passively copied alongside the host genome. The bacterial hosts are typically somewhat unaffected by this procedure because the phage genome is typically quite tiny.
