Answer:
Our sun is extremly hot. like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star
Explanation:
Answer:
option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
Justification:
The electronegativity of an element accounts for its relative ability to attract electrons.
Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.
Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.
The human digestion starts in the small intestine gets the
most of the nutrients in your food, and your circulatory system passes them on
to other parts of your body to store or use.
When food enters the small intestine, villi along the intestine wall
along with enzymes help break down the food, and takes a long journey. The
stomach is right above the small intestine, and the small intestine is all
wrapped around, and isn't that thick. Nutrients from the food are released to
the whole body as energy. The small intestine brings the food to the large
intestine, which is five feet long and is near your pelvis, or hips. The large
intestine connects to the rectum, and then to the anus. In the large intestine,
all the water is absorbed as well as salt.
