Answer:
The preferable option will be - 1.
1. "Administer the antibiotics until they are gone."
Explanation:
- A myringotomy is the insertion of tympanoplasty tubes into the middle ear to promote drainage of purulent middle ear fluid, equalize pressure, and keep the ear aerated.
- The nurse must instruct parents regarding the administration of antibiotics.
- Antibiotics need to be taken as prescribed, and the full course needs to be completed.
- The parents should complete the full course antibiotic therapy.
The answer is B because A is being changed .
The part of the brain which plays a key role in forming and storing the implicit memories created by classical conditioning is the Cerebellum.
As well known, the central nervous system (CNS) is made up of the brain and spinal cord. The peripheral nervous system (PNS) on the other hand is composed of spinal nerves that branch from the spinal cord.
The brain is subdivided into 3 parts:
- The Cerebrum which is the largest part of the brain and is composed of right and left hemispheres and is responsible for performing higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
- The Cerebellum which is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance. An additional function of the cerebellum is the formation and storage of memories created by classical conditioning.
- The Brainstem which acts as a relay means connecting the cerebrum and cerebellum to the spinal cord. It is responsible for many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.
Ultimately, The part of the brain which plays a key role in forming and storing the implicit memories created by classical conditioning is the Cerebellum.

Answer:
Advanced forms of life existed on earth at least 3.55 billion years ago. In rocks of that age, fossilized imprints have been found of bacteria that look uncannily like cyanobacteria, the most highly evolved photosynthetic organisms present in the world today. Carbon deposits enriched in the lighter carbon-12 isotope over the heavier carbon-13 isotope-a sign of biological carbon assimilation-attest to an even older age. On the other hand, it is believed that our young planet, still in the throes of volcanic eruptions and battered by falling comets and asteroids, remained inhospitable to life for about half a billion years after its birth, together with the rest of the solar system, some 4.55 billion years ago. This leaves a window of perhaps 200-300 million years for the appearance of life on earth.
divine interventionThis duration was once considered too short for the emergence of something as complex as a living cell. Hence suggestions were made that germs of life may have come to earth from outer space with cometary dust or even, as proposed by Francis Crick of DNA double-helix fame, on a spaceship sent out by some distant civilization. No evidence in support of these proposals has yet been obtained. Meanwhile the reason for making them has largely disappeared. It is now generally agreed that if life arose spontaneously by natural processes-a necessary assumption if we wish to remain within the realm of science-it must have arisen fairly quickly, more in a matter of millennia or centuries, perhaps even less, than in millions of years. Even if life came from elsewhere, we would still have to account for its first development. Thus we might as well assume that life started on earth.
How this momentous event happened is still highly conjectural, though no longer purely speculative. The clues come from the earth, from outer space, from laboratory experiments, and, especially, from life itself. The history of life on earth is written in the cells and molecules of existing organisms. Thanks to the advances of cell biology, biochemistry and molecular biology, scientists are becoming increasingly adept at reading the text.
An important rule in this exercise is to reconstruct the earliest events in life's history without assuming they proceeded with the benefit of foresight. Every step must be accounted for in terms of antecedent and concomitant events. Each must stand on its own and cannot be viewed as a preparation for things to come. Any hint of teleology must be avoided.
After the Cretaceous–Paleogene extinction event wiped out the non-avian dinosaurs (birds being the only surviving dinosaurs) and several mammalian groups, placental and marsupial mammals diversified into many new forms and ecological niches throughout the Paleogene and Neogene, by the end of which all modern orders had appeared.
