Answer:
New Moon
Explanation:
This is when the moon is between the sun and the earth. The side of the moon that faces the earth is in darkness hence cannot be viewed with the aided eye from the earth and the sun and moon rise and set together. During the daytime the glare of the sun makes it harder for us to see the new moon. A slight halo is visible around the moon because some light from the sun which is behind the moon goes around the. When the new moon just crosses the elliptic orbit blocking the sun rays from reaching earth and causing a shadow over the earth, this is when a solar eclipse occurs. You realize that the moon’s orbit is inclined relative to the ecliptic orbit hence solar eclipse does not occur with every new moon.
Answer:
The Richter scale is a numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations. The more destructive earthquakes typically have magnitudes between about 5.5 and 8.9; the scale is logarithmic and a difference of one represents an approximate thirtyfold difference in magnitude.

Answer:
In a fruit fly experiment, grey body, normal winged (homozygous dominant) fruit flies were mated with black body, short winged (homozygous recessive) fruit flies. The F1 dihybrid females were then used in a test cross. If the genes are always linked and no crossing over occurs, what would be the predicted ratio in the F2 generation?
GG x bb = Gb, Gb, Gb and Gb F1 generation
grey body heterozygous offspring 4:0
Gb x Gb= GG, Gb, Gb, and bb F2 generation
3:1 three grey body fly and one black body fly
