True
Not exactly. Circadian rhythms are a subset of diurnal rhythms. Diurnal rhythms reoccur daily and can be circadian and non-circadian. Circadian rhythms can be set by the environment (entrainment), but are not dependent on environment stimulus for continuation (free-running) (ie. hormone secretion). Non-circadian rhythms are responsive to the environment, but still operate on a daily cycle (ie. the process of photosynthesis).

That depends on what you're relating the spin to. If the Earth did not spin relative to space itself, there would be a diurnal cycle. However, each 'day' would last half a year, with the other half occupied by one night. If the Earth did rotate, but did not rotate relative to the Sun, we would be in much the same situation the Moon is in with us - one face always showing to the Sun, the other always hidden. In this scenario, we would have no diurnal cycle.
The human brain is larger. The positioning of the hind brain is different, due to the erect position of humans. Convolutions are increased in humans (increases surface area). The sheep's brain has a smaller cerebellum (lesser motor control/less complex learned motor behaviors). There is a larger pineal gland in sheep (related to circadian rhythms/seasonal reproduction).
No, the pineal gland and the pituitary gland are not the same. The pituitary gland is located below the hypothalamus connected to it by the infundibulum. The pituitary is responsible for the secretion of oxytocin, antidiuretic hormone, melanocyte-stimulating hormone, thyroid- stimulating hormone, prolactin, adrenocorticotropic hormone, follicle-stimulating hormone, luteinizing hormone, and growth hormone. In contrast, the pineal gland is part of the epithalamus attached to the third ventricle. Cells of the pineal gland convert serotonin to melatonin which helps regulate the body's circadian rhythms.

The three main tidal patterns are Diurnal, Semi-diurnal, and Mixed Semi-diurnal. If an area has one high tide and one low tide each day it is called Diurnal. If the area has two high tides and two low tides of the same height , it is called Semi-diurnal, if the tides are differing heights it is called mixed Semi-diurnal.
It is where two or more different rhythms are going on at the same time.Polyrhythm is when two rhythms or melodies are played at once and contrast/match together.
polyrhythm
Circadian rhythms are time schedules in which the body uses to function. These schedules include sleeping and eating patterns, patterns of bowel movement and urination, and several other things.
Whether a snake is diurnal or nocturnal does not affect if it is venomous. Some are venomous but most are not. The same is true of nocturnal snakes. If you see any snake and are not sure if it is venomous, don't take the risk.
it is when 2 different rhythms are being played at the same point, working with one another.
Absolutely not. Some animals are nocturnal, and others are diurnal. I can eat 24/7 -but I'm not proud of that!

biosystem, ecosystem, subsystem
No. Together they act as a CNS depressant. Taking both at the same time can not only knock out your ability to breath...it can cause irregular heart rhythms. In short, it can be fatal.
