Answer:

B. Colds can be caused by hundreds of different viruses.

Explanation:

The common cold is a benign viral infection of the upper respiratory tract, which mainly affects the nose and throat. The most common symptoms are: nasal congestion, runny nose, sneezing and sore throat. This is one of the most common diseases that exist. Eventually, everyone will get a cold more than once in their life.

More than 200 viruses can cause colds, all of which are respiratory transmission, which makes contagion extremely effective. Cold viruses enter the body through the lining of the mouth, eyes or nose. The most common is to bring the contaminated hand to the face. This port carries viruses acquired by manual contact with colds or contaminated objects.

There is also the possibility that viruses reach these mucous membranes, through invisible droplets, suspended in the air, after a person with a cold sneezes, coughs or talks. It is estimated that for this form of contagion, there is a need to be less than one meter from the infected person.

Is the following statement true or false? the most frequent sign and symptom of a developing pulmonary embolus is tachypnea and

Rainbow [258]

The statement is True.

Dyspnea has a multi-factorial origin, resulting from bronchospasm or vasospasm, disturbances in pulmonary circulation, immobility or diminished respiratory excursion of the diaphragm, atelectasia and/or pulmonary infarction, anoxia, or impairment of cardiac function.

Dyspnea, chest pain, and cough are the most frequent symptoms of Pulmonary Embolism(PE), while fever, tachycardia, abnormal pulmonary signs, and peripheral vascular collapse are the most common physical findings.

Pulmonary embolism (PE) occurs when a blood clot gets stuck in an artery in the lung, blocking blood flow to part of the lung. Blood clots most often start in the legs and travel up through the right side of the heart and into the lungs. This is called deep vein thrombosis (DVT).

Clot in the lung circulation (pulmonary embolus): Breathlessness is usually sudden and associated with rapid breathing and may be accompanied by chest pain.

What does natural selection favor?

ratelena [41]

Answer:

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

The reason that natural selection is important is that it's the central idea, stemming from Charles Darwin and Alfred Russel Wallace, that explains design in nature. It is the one process that is responsible for the evolution of adaptations of organisms to their environment.

klio [65]

Answer:

Explanation:

Crude oils, shale, and natural gas are some of the fossil fuels formed in this way. They are specially formed when vast amounts of algae die and sink to the bottom of the oceans over time and accumulate with sediments. They become buried under vast layers of sediments that apply high pressure. Over time, the high pressure and temperature turn the organic molecules into fossil fuels.
