We eat food for nutrients and energy. Our digestive system does the work to physically and chemically digest or decompose the fo

od we eat. But how do the nutrients and energy-rich molecules get to our cells? What systems and organs are involved? A) The digestive and cardiovascular systems are involved. Digestion takes place in the intestines and nutrients and carbohydrates are absorbed into the blood there for distribution to all cells. Eliminate B) The digestive and excretory systems are involved. Digestion takes place in the intestines and nutrients and carbohydrates are absorbed into the blood stream; wastes leave the body via the excretory system. C) The digestive, cardiovascular and skeletal systems are involved. Digestion is completed in the small intestines. Sugars, fats and amino acids are absorbed into the bloodstream and nutrients into the bone marrow of the skeletal system. D) The digestive, cardiovascular and lymphatic systems are involved. Digestion is completed in the small intestines. Nutrients, sugars and amino acids are absorbed into the bloodstream and glycerol and fatty acids into the lymphatic system.

The difference that exists between the inner and outer planets is - D. None of the inner planets have rings, whereas all the outer planets have rings.

Planets in the solar system are divided into two groups on the basis of distance from the sun are Inner planets and outer planets. The inner planets are closer to the sun compared to the outer planets.

Inner planets:

  • include four planets - Mercury, Venus, Earth, and Mars.
  • Also called terrestrial planets
  • small and rockier
  • very less or no natural satellites
  • No rings around them

Outer planets:

  • include Jupiter, Saturn, Uranus, and Neptune

As the sky diver falls to earth, she experiences positive acceleration due to
Sauron [17]

Answer:

The gravitional pull of the Earth

Explanation:

Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Since the earth has more it will cuase you to be, almost attracted by it.

Also, Gravity is inversely proportional to the square of the distance that separates the two bodies. Hence gravity will decrease as one will go higher in altitude, and hence away from the center of mass.

But since your falling from a plane, or some other type of aircraft, your moving closer to the center of mass, hence your gravitational pull get stronger as you falling closer-and-closer to the ground.
