El componente gaseoso que faltaba en la atmósfera primitiva y que hoy es esencial para la vida es:

Explanation:

Se tiene constancia de que en sus inicios, la atmósfera de la Tierra estaba compuesta por los gases resultantes de las diferentes erupciones volcánicas (ya que la actividad volcánica de dicha era fue demasiado alta), por lo tanto, era normal tener una atmósfera compuesta por azufre, dióxido de carbono, nitrógeno (que hoy en día es más del 70% del aire que respiramos) e incluso agua en estado gaseoso, sin embargo, la presencia del oxígeno [tex]O_{2}[/tex] era sumamente baja, casi inexistente, actualmente su presencia en el aire es de un poco más del 20% y es sumamente importante para diferentes funciones en los seres vivos, incluso los seres vivos acuáticos que se abastecen del oxígeno disuelto en el agua, esta es la razón por la cual, si tienes una pecera con peces en tu casa, debes instalarle un sistema que abastezca de oxígeno constantemente a tu peces mascota.

The answer is D bc looking is destroying the owls home that answer is not c bc this has nothing to do with the owl

In parts of the northwestern United States, logging is destroying many of the forests that are home to the spotted owl, the following is the primary threat to the spotted owl population: loss of habitat that is in option D.

The destruction or degradation of a natural environment in which a specific species of animal or plant lives, as a result of deforestation, urbanization, industrialization, and other factors, is referred to as habitat loss. As a result of the loss of habitat the plants and animals that live there are forced to adapt to the new conditions as a result of habitat loss.

Hence, in parts of the northwestern United States, logging is destroying many of the forests that are home to the spotted owl, the following is the primary threat to the spotted owl population: loss of habitat that is in option D.

C. ... the pH tell us whether the water, a substance is acidic or basic.. but know that water is neutral

Answer:

C is the correct answer here.

Most of the baryonic matter (ordinary matter) of the universe is interstellar gases and stars. Baryonic matter is the visible matter. Thus, the correct answer is D.

Visible matter is also known as the baryonic matter. It consists of baryons which are subatomic particles such as protons, neutrons and electrons.

In cosmology, baryonic dark matter is the dark matter composed of baryons. Only a small proportion of the dark matter in the universe is likely to be baryonic the rest of the matter is all dark matter. Baryonic matter only includes matter composed of baryons.  It can be described as the baryons are made up of protons, neutrons and all the objects composed of them (i.e. atomic nuclei), but exclude other things like electrons and neutrinos.

Therefore, the correct answer is D.

Explanation:

Heat therapy is said to work because of its analgesic properties or its ability to bring blood to the area which can penetrate deep into the muscular tissue. However, heat therapy is also said to work because it is comforting on a psychological level. According to Lorimer Moseley “to reduce pain, we need to reduce credible evidence of danger & increase credible evidence of safety” and applying heat makes us feel safe. Why? Because the cold kills!  

Despite this, there is little evidence to show that it helps alleviate pain at certain trigger points  (small patches of acutely sensitive soft tissue) in the body and there is less evidence to show that it works for period pain. One study has claimed that heat can work for period pain however the researchers failed to differentiate if their exercise programme or the psychological effect of feeling warm eased their pain. This kind of testing means that other variables influence participants’ perception of pain and we can’t be certain if the heat therapy actually helped. What we do know is there are certainly drawbacks to this kind of treatment.

Explanation:

The drainage pattern one is expected to see in the limestone is trellis. The correct option is C.

Trellis drainage patterns form when sedimentary rocks like limestone are rolled up or slanted and then stripped away to varying degrees depending on their strength.

The Rocky Mountains of British Columbia and Alberta are prime examples of this, with trellis patterns found in many of the drainage systems.

Thus, the correct option is C.

Answer:

B. Blood in the left ventricle is deoxygenated.

Explanation:

Human heart consists of four chambers namely: right atrium, right ventricle, left atrium and left ventricle. These chambers work hand in hand to perform the function of circulating blood throughout the body.

- The RIGHT ATRIUM receives deoxygenated blood from the heart and passes it to the RIGHT VENTRICLE, which pumps it to the lungs in order to be oxygenated.

- The LEFT ATRIUM receives oxygenated blood from the lungs and passes it to the LEFT VENTRICLE, which pumps it into the body.

- Also, the pulmonary artery carries deoxygenated blood into the lungs for oxygenation while the pulmonary veins carry oxygenated blood from the lungs

Based on the above explanation of the right & left atria and the right & left ventricles, it is FALSE that the blood in the left ventricle is deoxygenated. It is rather oxygenated.

1.Dry ice is the solid form of carbon dioxide. It is used primarily as a cooling agent, but is also used in fog machines at theatres for dramatic effects. Its advantages include lower temperature than that of water ice and not leaving any residue.

2.The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century.

3.Ammonia gas

Ammonia gas is used as a developer in diazotype method to make blue prints.

4.The International Union of Pure and Applied Chemistry (IUPAC /ˈaɪjuːpæk, ˈjuː-/) is an international federation of National Adhering Organizations that represents chemists in individual countries.

5. All metals have some amount of resistivity to electrical currents, which is why they require a power source to push the current through. The lower the level of resistivity, the more electrical conductivity a metal has. Copper has low resistivity, and therefore is an excellent conductor.
