One autumn in the late 1990s, a number of people became ill after working at a single building at an industrial plant in a neigh

Gekata [30.6K]

This disease is likely caused by a bacterium that was transported through the water. If water was infected only locally, likely, there are no outbreaks.

<h3>What can be guessed about the causative organism?</h3>

The causative organism seems to be a type of bacteria in water. This is because disinfecting the water systems seemed to be the problem, which shows the source was there.

<h3>How are these bacteria transmitted?</h3>

The suspected bacteria is transmitted through water. This seems to be the main transmission route because it seems workers experienced symptoms after drinking water.

<h3>Is there a risk for more outbreaks?</h3>

If only the water of the plant was contaminated with this bacteria, it is likely there are no outbreaks. However, if contamination was general, outbreaks might appear.

How does the amount of sunlight that receive affect the height of the plants ?

IRISSAK [1]

A plant needs sunlight to grow, it also needs carbon dioxide, and water. The plant needs sun so it can make oxygen for animals and us, but also it gives it stuff to make glucose witch it needs. The plant needs it to survive.

¿Porque lavarse con jabon y no solo con agua ?

Yanka [14]

Answer:

El jabón permite eliminar las gotas del virus expulsadas por otra persona, las cuales se pueden encontrar en diversas superficies.

Explanation:

La Organización Mundial de la Salud establece que una de las formas para evitar la propagación del virus es con el lavado constante de las manos con jabón. Esta medida se debe a que las personas a lo largo del día llegan a tocar diversas superficies y a manipular objetos que pudieran haber entrado en contacto con alguien que tiene el virus. Como una persona no puede identificar si en alguna superficie u objeto hay partículas del virus, la prevención es lavarse las manos.

Se sabe que el virus se puede encontrar en cualquier superficie u objeto que una persona toque, este puede permanecer ahí durante horas acorde del material con el cual este fabricado. Si la persona toca algo y directamente lleva sus manos a cualquier parte de la cara como boca, nariz u ojos, el virus puede entrar y producirse el contagio.

Help if good at earth science/ space pls!!

Answer:

1. The proportion of the universe's galaxies that can be seen from Earth is approximately 10 per cent (option a).

2. The model of galaxy formation in which sections of gas clouds collapse into small pieces which repeatedly combine into larger pieces under the influence of gravity is called the SZ model or the bottom-up model.

3. Most stars are not destroyed in a galaxy collision because galaxies move too slowly for that kind of damage (option c).

4. It is estimated that the galaxies in the universe have evolved since about 13.8 billion years ago, just after the universe first formed (option b).

Explanation:

1. What we can see of the universe is due to distant stellar objects, whose light has reached us. Current estimates indicate that there may be as many as 2 billion galaxies in the entire universe, many of which are not visible.

Using the "Hubble" space telescope would only allow the observation of 200 billion galaxies and study their composition, which represents about 10 per cent of existing galaxies.

In the future, through the use of more powerful and higher resolution telescopes, it would be possible to observe galaxies that cannot be studied so far.

2. Leonard Searle and Robert Zinn proposed, in 1978, a model for the formation of galaxies, in which small units -globular clusters- associated with each other to progressively form larger components.

Globular clusters are the product of the collapse that occurred before galaxies began to form, and are capable of uniting under the effect of gravity to form larger clusters and thus form the galaxy. The name "bottom up" is due to the fact that small elements form larger ones. Likewise, the name "SZ" results from the initials of the scientists who proposed it.

3. Galaxy collisions are a form of gravity-dependent interaction between galaxies, with one having an effect on the other.

The result of the collision of two galaxies, in general, is the fusion of both, where the larger one is capable of absorbing the smaller one .without this involving the destruction of stars- since the movement of the colliding galaxies is very slow.

4. The formation of galaxies has a calculated time of about 13.8 trillion years, about 500 or 600 million years after the Big Bang.

It is believed that the origin of galaxies reside in the gravitational instability induced primitive fluctuations, leading to the formation of dense units from the scattered gases. This condensation of gases is called clusters or superclusters, and galaxies may have formed from them.
