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.
The question is incomplete as it does not have the options which are:
A) single-stranded complementary tails
B) blunt ends
C) poly-A sequences
D) 5' cap
E) interference
Answer:
A) single stranded complementary tails
Explanation:
Restriction endonuclease is the enzyme which cuts the DNA sequence in the internal sequence.
The endonuclease enzyme can cut the DNA sequence in a way that it can form the cuts with the single-stranded overhangs called sticky ends and without overhangs called blunt ends.
The sticky ends are produced when the enzyme makes cut at the single strand and then makes the cut at between the same base at the nitrogenous base. This type of asymmetrical cut forms the single-stranded overhangs which can form the complementary base pairs easily.
Thus, Option-A is correct.
1) The limbs of a bat and the forelimbs of a bird is an example of Analogous structures
2) The arm of a human and the arm of chimpazee is an example of Homologous structures
3) Frogs and salamanders is an example of Homologous structures
<span>Homologous structures, are organs or systems of different living beings
that have a common origin, but different adaptations. For example, the
extremities of a dog and a dolphin, are homologous, have similar bones, only
that some adapted to the race and others to swimming. On the other hand,
analogous structures are organs or systems of different living beings that do
not have a close origin in common, but are adapted to the same environment, for
example, fins of fish and dolphin fins, the function is the same, the origin is
different; or the wings of birds and the wings of insects.</span>

Answer:
Azúcar.
Explicación:
El azúcar es una molécula que almacena energía y se mezcla con el agua. el azúcar es un disacárido compuesto por átomos de fructosa y glucosa. Es una fuente de carbohidratos que contiene una gran cantidad de energía que se utiliza en diversas actividades. Después de la descomposición de los carbohidratos, se produce glucosa que es utilizada por las mitocondrias de la célula para producir moléculas de energía en forma de ATP.
