Evaporation, condensation, precipitation are all part of the water cycle. After the precipitation, the “destiny” of the water is ground water or surface runoff.
Groundwater is the term for all the waters beneath Earth’s surface, that fills in porous spaces in soil, sediment, and rocks. But, when falling rain cannot be absorbed by soil (saturated by water) and become groundwater, it flows over the surface and this is called surface runoff. Groundwater has its zones: vadose zone (right beneath the ground, unsaturated zone), water table (water pressure head is equal to the atmospheric pressure), zone of saturation (saturated with water).
A watershed is the land area that drains into a body of water.
the formula to find force is F=ma
F- Force (in newtons)
m- mass (in kg)
a- acceleration (in m/s)
in this case you need to find acceleration, so isolate a by making the formula a=f/m. plug in your numbers then you're done
a=30/70
a=0.429 (rounded)
Answer:
The correct answer would be option E) 42.
Explanation:
The number of chromosomes present in the body cells typically is 2n or diploid which means a pair of the chromosome. The body cells or somatic cells are always diploid and two times more than the sex cells which called haploid. Haploid cells are produced during sexual reproduction.
In any offspring, half the number of chromosomes of the total pair of somatic chromosomes comes from both the parents. Similarly here the chromosome that derived from the donkeys is half of 62 that is 31, as it is already given that zonkeys have 52 chromosomes so the chromosome that come from the zebra would be 21 (52-31=21). hence the somatic chromosome number of the zebra would be 42 ( 2n =2 times of 21)
Thus, the correct answer would be option E) 42.
