The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
Thank you for your time on brainly , hope this answer helps. Have a great day!
Answer:
The moon is about one-fourth the size of Earth.
Explanation:
- The Moon has a diameter of 3,476 km and is one-fourth of the size of the earth. Moon is about 27% lesser than the size of the earth.
- Earth's moon is the fifth largest moon in the solar system having a radius of 1,737 km.
- The surface area covered by the moon is about 37.9 mn km square. It is even smaller than the continent of Asia. The moon's mass is about 1.2% of the mass of the earth.
Evolution Due to environmental factors, It may not look it, but, needles are leaves, they collect solar radiation to produce glucose through the process of photosynthesis, however, needles are, some would say, evolutionary superior to leaves. Needles themselves hold in more water due to their dense wax coating, they are very difficult for insects and other organisms to eat, one because of their structure, and two because of their acidity, they can catch sunlight all year long due to their winter resilience( they don't fall, during the winter), and they have less surface area for wind to catch, which leaves them better protected from wind than most deciduous trees, however the surface area can also pose a larger problem for less surface area means less sunlight interception, therefore more are needed to compete against regular leaves. But.. I Digress... Plant needles are 'PROBABLY' initially the result of evolution of narrow leaves due to climate or environmental factors.
Sry its so long got carried away! Hope this helps xD
