Osteoporosis refers to an ailment characterized by reduced bone mass and loss of bony tissue that may lead to weak and fragile bones. In an experiment, Dr. Travis tested the influences of the consumption of calcium on osteoporosis, the condition that results in enhanced chances of bone fractures.
In the given experiment, the amount of calcium is the independent variable, and the risk of bone fractures could get changed with the amount of calcium consumption.
Like all planets and most stars, the motion of the sun is directly related to the rotation of it's axis.
I believe the answer to this is molecule.
The minimum hydrogen to helium ratio is 3:1
Answer:
(2) low power: 100 small pollen grains
high power: 25 large pollen grains
Explanation:
Compound light microscopes are devices used to greatly magnify objects. They have several objective lenses, a low-power lens magnifies 10 times (10X) the objects, and the high-power lens magnifies them 40 times (40X).
For that reason, when observing the pollen grains with the high-power lens the student will see them bigger than with the low-power lens. However, the field of view (the visible area through a lens) is reduced when a higher power lens is used, so fewer pollen grains will be seen.
The answer therefore is the option of higher number of pollen grains of small size for the low-power lens, and lower number of pollen grains of larger size for the high-power lens.
