Question: Plants and various other groups of photosynthetic eukaryotes collectively known as "algae" have unique organelles known as chloroplasts. Chloroplasts are thought to be descended from cyanobacteria that formed endosymbiotic relationships with ancient plant and algal ancestors. Chloroplasts and cyanobacteria contain the blue-green pigment chlorophyll a. Chlorophyll a (as well as its plant and green algal-specific cousin chlorophyll b)[a] absorbs light in the blue-violet and orange/red parts of the spectrum while reflecting and transmitting the green light that we see as the characteristic colour of these organisms. The energy in the red and blue light that these pigments absorb is used by chloroplasts to make energy-rich carbon compounds from carbon dioxide and water by oxygenic photosynthesis, a process that generates molecular oxygen (O2) as a by-product.
Try to answer this question if possible: What organelles are unique to algae?
Answer: chloroplasts
Question: The history of emotions has become an increasingly popular topic recently, with some scholars arguing that it is an essential category of analysis, not unlike class, race, or gender. Historians, like other social scientists, assume that emotions, feelings and their expressions are regulated in different ways by both different cultures and different historical times, and constructivist school of history claims even that some sentiments and meta-emotions, for example Schadenfreude, are learnt and not only regulated by culture. Historians of emotion trace and analyse the changing norms and rules of feeling, while examining emotional regimes, codes, and lexicons from social, cultural or political history perspectives. Others focus on the history of medicine, science or psychology. What somebody can and may feel (and show) in a given situation, towards certain people or things, depends on social norms and rules. It is thus historically variable and open to change. Several research centers have opened in the past few years in Germany, England, Spain, Sweden and Australia.
Try to answer this question if possible: What historical school claims that sentiments and meta-emotions can be learned?
Answer: constructivist
Question: The first record of the existence of a settlement at Plymouth was in the Domesday Book in 1086 as Sudtone, Saxon for south farm, located at the present day Barbican. From Saxon times, it was in the hundred of Roborough. In 1254 it gained status as a town and in 1439, became the first town in England to be granted a Charter by Parliament. Between 1439 and 1934, Plymouth had a Mayor. In 1914 the county boroughs of Plymouth and Devonport, and the urban district of East Stonehouse merged to form a single county borough of Plymouth. Collectively they were referred to as "The Three Towns".
Try to answer this question if possible: What was the name of the Plymouth-area settlement recorded in the Domesday Book?
Answer: Sudtone
Question: Saxophones appear in some scores from the late 19th century onwards. While appearing only as featured solo instruments in some works, for example Maurice Ravel's orchestration of Modest Mussorgsky's Pictures at an Exhibition and Sergei Rachmaninoff's Symphonic Dances, the saxophone is included in other works, such as Ravel's Boléro, Sergei Prokofiev's Romeo and Juliet Suites 1 and 2 and many other works as a member of the orchestral ensemble. The euphonium is featured in a few late Romantic and 20th-century works, usually playing parts marked "tenor tuba", including Gustav Holst's The Planets, and Richard Strauss's Ein Heldenleben.
Try to answer this question if possible: Who wrote The Planets?
Answer:
Gustav Holst
