question:
Sarvastivada teachingswhich were criticized by Nagarjunawere reformulated by scholars such as Vasubandhu and Asanga and were adapted into the Yogacara school. While the Madhyamaka school held that asserting the existence or non-existence of any ultimately real thing was inappropriate, some exponents of Yogacara asserted that the mind and only the mind is ultimately real (a doctrine known as cittamatra). Not all Yogacarins asserted that mind was truly existent; Vasubandhu and Asanga in particular did not.[web 11] These two schools of thought, in opposition or synthesis, form the basis of subsequent Mahayana metaphysics in the Indo-Tibetan tradition.
answer:
What teaching were criticized by Nagarjuna?

question:
Certain genera of Gram-positive bacteria, such as Bacillus, Clostridium, Sporohalobacter, Anaerobacter, and Heliobacterium, can form highly resistant, dormant structures called endospores. In almost all cases, one endospore is formed and this is not a reproductive process, although Anaerobacter can make up to seven endospores in a single cell. Endospores have a central core of cytoplasm containing DNA and ribosomes surrounded by a cortex layer and protected by an impermeable and rigid coat. Dipicolinic acid is a chemical compound that composes 5% to 15% of the dry weight of bacterial spores. It is implicated as responsible for the heat resistance of the endospore.
answer:
What are highly resistant dormant structures of certain gram-positive bacteria called?

question:
Asthma is characterized by recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing. Sputum may be produced from the lung by coughing but is often hard to bring up. During recovery from an attack, it may appear pus-like due to high levels of white blood cells called eosinophils. Symptoms are usually worse at night and in the early morning or in response to exercise or cold air. Some people with asthma rarely experience symptoms, usually in response to triggers, whereas others may have marked and persistent symptoms.
answer:
What are the characteristics of asthma?
