The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane. The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. The pharynx on the other hand referred to as the throat is part of both the digestive and respiratory systems. For the digestive system, its muscular walls function in the process of swallowing, and it serves as a pathway for the movement of food from the mouth to the esophagus.
Explanation:
In the given question, the DNA segment of human can be sequenced or analysed through three processes:
2. DNA sequencing: DNA sequencing is the method by which the sequence of the nucleotides which are adenine, thymine, guanine and cytosine are sequenced in the correct order.
1. DNA probes: probes are synthesised nucleotide sequence which binds to specific sites of DNA. Since these probes are complementary to the specific region therefore the DNA polymorphic sequence can be sequenced.
3. Polymerase chain reaction: PCR is the technique which can amplify or replicate the DNA sequence but this involves the isolation of specific DNA sequence.
Answer:
Mitosis produces two cells from one parent using one division event. But meiosis produces four new child cells with two divisions, each of which has half the genetic material of its parent.
Explanation:
Chemical energy: When animals eat plant, they get the chemical energy in the plants stored as sugar.Mechanical energy: Carbon dioxide rising through the air gains mechanical energy (as well as gravitational potential energy).Thermal energy: The heating of fossil fuels releases the energy stored inside.Electrical energy: Burning fossil fuels creates electrical energy for us to use.
Answer:
All of the choices are correct
Explanation:
The respiratory syncytial virus (RSV) is an enveloped, negative-strand RNA virus (Paramyxoviridae family) capable of infecting ciliated cells of the airways by using its surface glycoproteins G and F for attachment and fusion during viral entry in target cells. RSV can affect the lungs and parts of the respiratory system (e.g., nasopharynx). Although RSV generally causes mild, cold-like symptoms, this virus may also lead to severe infection in babies (12 months) and infants, being one of the most common types of respiratory infections in children, older adults, and immunocompromised patients. Some common symptoms in individuals with RSV pneumonia include fever, nonproductive cough, dyspnea, wheezes, rales, rhonchi, etc.
