Answer:
F= 25/2 = 12.5N
Explanation:
When you use a compound pulley the force required depends on the mechanical advantage of the compound pulley. This is known as rate of loss of distance or the ratio of the force to the load.
M.A = Effort distance /Load distance. OR M.A = Load/Effort

</span>Meiosis has 2 cell divisions but mitosis has only one cell
division. Meiosis I is same as mitosis because parent cell produces diploid
cells. But the difference between meiosis and mitosis is after the complete
process meiosis produces genetically different haploid daughter cells and
mitosis produces genetically same diploid daughter cells.

</span>The main advantage of the sexual reproduction is It helps to produce offspring which can be
well adapted to the environmental conditions due to the genetically
differentiations. Hence, there are various types of offspring in the population.
But the disadvantage is it requires two parents and it requires more time than
asexual reproduction.
<span>3.
</span>Advantages
of asexual reproduction are it requires only parent, time for the process is
relatively low, it produces genetically identical offspring. The main
disadvantage is due to the production of genetically identical offspring, the
survival rate is low when there is a disaster.
<span>4.
</span><span>The
organism can do either sexual reproduction or asexual reproduction to produce
offspring. If it is difficult to find a partner to mate, the living being can
do asexual reproduction to make offspring in a short period of time. When the
organism needs genetically different offspring for survival, they can do sexual
reproduction.</span>
