Answer:
zenith distance = 39 degree
Explanation:
given data
declination of star = -13.00º
latitude = 26.00º N
to find out
distance in degrees between the star and zenith
solution
we know the formula that is
latitude = star declination+ its zenith distance ....................1
and
zenith distance = latitude - star declination
zenith distance = 26 - ( -13 )
zenith distance = 26 + 13
zenith distance = 39 degree
The Correct Answer : <u>Flooding the fields causes the soil to degrade so weeds cannot take root.</u>
Rice has a submerged growth state while most weeds do not. Therefore, flooding rice fields reduces the growth of these less robust pests without negatively affecting the rice crop. Flooding the fields also deters many kinds of vermin that would otherwise live in the soil and harm the rice plants because they cannot breathe underwater.

Answer:
E. All of these objects rise in the east and set in the west.
Explanation:
The Earth is spinning on its axis towards the east.
For this reason all of the object they are outside the earth such as Galaxies, sun, stars and the moon, Will Rise in the East and set in the West.
The earth spinning on its axis because of the gravitational pull that the sun exercise on it, and it's the reason why we have a day and a night.
The earth,beside moving on its axis, is moving in relationship to the sun, and this Orbit last 365 days (a year), and there is also a change in the inclination of the axis which is called a precessional cycle.
