Answer: 
Explanation:
The Tropic of Cancer is one of the parallels (imaginary line around the Earth parallel to the equator) located in the northern hemisphere (currently its latitude is 
).
It is called "Cancer" because a long time ago, when the summer solstice occurred in the northern hemisphere (on June 20th or 21st), the Sun was in the constellation Cancer (the crab).
Now, if we were just in the North Pole, Polaris would by exactly over our heads (
over the horizon), but as we go south and find the Tropic of Cancer parallel, Polaris altitude will be approximately at an angle of over the horizon.
Hence, the altitude of Polaris measured by an observer at the Tropic of Cancer is .
Answer:
b) A series of stars that form a figure
Explanation:
In astronomy, <em>a constellation is any of certain groupings of stars that form an imaginary outline or pattern on the celestial sphere. </em>They are useful to track artificial satellites and in assisting astronomers and navigators to locate certain stars, therefore constellation is a series of stars that form a figure. A constellation can't be a region of the celestial sphere and all of the stars in it because not all stars in the celestial sphere form figures.
They are no figures in the night sky because constellations are starts, therefore they are present during day or night, it's not a term applicable to astrology because this is a pseudoscience not based on facts, like astronomy.
I hope you find this interesting and useful! Good luck!
The correct answer is B. Cells divide, producing more cells.
Explanation
The cell is the basic unit of life for all living things. Likewise, it is a form of classification for them since living organisms can be classified according to the number of cells they have unicellular (a single cell), multicellular (more than one cell). In organisms that have more than one cell, they divide to produce more cells and form the organs and tissues themselves. Cell division can occur from two processes that are mitosis and meiosis in which two and four cells are produced respectively. According to the above, the correct answer is B. Cells divide and producing more cells.
