Answer: ok so Most of the energy in the Earth system comes from just a few sources: solar energy, gravity, radioactive decay, and the rotation of the Earth. Solar energy drives many surface processes such as winds, currents, the hydrologic cycle, and the overall climate system. Gravity makes rivers and other materials flow downhill and creates tides (from the Moon's gravitational pull). Radioactive decay creates heat in the Earth's interior, while Earth's rotational forces influence currents of air and water.
Explanation:
The best answer is d. endometrium.
Endometrium is the innermost layer in the Uterus, and it is found in the whole uterus.
For comparison, Cervix is the structure on the "bottom" of the uterus, vagina is below it (outside of the womb) and the ovaries if where the unfertilized eggs are.
The 10% rule means that when energy is passed in an ecosystem from in trophies level to the next , only 10 percent of the energy will be passed on. but ten percent of the energy in organic matter is stored as flesh , the remains is lost during transfer. or broken down in reespirations.
Culturing of microbial organisms allows experts to determine what type of organism is present and at what conditions it abundantly exist. This is an essential tool to determine the cause of contagious/infectious disease so that experts will have a clear understanding how to combat it.
