When encountering wild animals, it is wisest to assume a defensive posture.
In military terms it is an order to assume positions to resist a possible attack. To maintain a stable and upright position
It is important to assume proper posture while still young because once we become accustomed to it, we would not feel any pain when we grow up. At our old ages, we would have a less chance of getting Osteoporosis. Young as we are, we need to practice these habits so that it would not be hard for us to adjust our imperfections.

The "downward" on the "curved surface" is a 3D model to explain and visualize the effect.
# # cerebral relates to cerebrum and posturing means to cause to assume a given posture....so you can make out what it means... samit subba, darjeeling....
You also need to know the index of refraction. For glass, that is usually somewhere around 1.5. The Wikipedia article on "Lens (optics)" includes the "Lensmaker's equation"; usually you can use the "thin lens equation" (further down in the article) as a convenient approximation. Since for this question you don't know the radius of curvature, and the equation includes two radii of curvature (for the two surfaces), I suggest that you make one of the following simplifying assumptions: 1) Either assume that the lens has two surfaces of equal curvature (note: for the equation in the Wikipedia article, the signs would be opposite for both sides), 2) Or, assume that the lens has one flat side and one curved side.
There are many ways to assume a sitting position, and therefore just as many ways to describe it. The Western culture style of sitting is in a chair. The old-fashioned notion that sitting straight up is the best posture has been changed to a posture that is more reclined. Follow the link below for more information.
I assume you mean "Why do veins in the head and face lack valves?"The answer is due to being organisms with upright posture. You need valves in your legs to keep the blood from falling down to your feet, and instead propel the blood to your heart. Your head, though, is above your heart, so you don't want valves trapping the blood in the head. That would cause headaches and perfusion issues. So lacking valves allows blood to flow down to the heart.
I assume you meant a sweeper? It depends on the space available. Often a sweeper is stored under the stairs, in a broom cupboard, or even simply stood upright in the corner of the kitchen, etc.
I would assume this means face down with arms straight out- or cruciform as this is Superman:s usual flying posture. I have never heard this term used- a static breast stroke if you will, that seems to make sense.
