Answer:
D) Cloning to produce embryonic stem cells may lead to great medical benefits for many.
Explanation:
stem cells are considered as the greatest hope in medicine. Research in embryonic stem cells leads to effective and new treatment in many human diseases
In many countries the reproductive cloning in humans is totally illegal and unethical.
while in therapeutic cloning the blastocyst is not transferred to a womb instead, embryonic stem cells are isolated from the cloned blastocyst and are genetically matched to the donor organism.
therapeutic cloning also helped in the research and production of cells genetically identical to the patient.

Answer:
Option C, zygote
Explanation:
The complete question is
The cell produced by the fusion of an egg and a sperm is the
a. gamete
b. oocyte
c. zygote
d. germ line cells
e. somatic cell
Solution
During the process of fertilization in sexual reproduction, when a male gamete (sperm) and female gamete (egg) fuses they form a new cell known as zygote.
Both male and female gamete are haploid with”n” number of chromosomes (only a single set of genes) and when they combine they form diploid zygote with “2n” number of chromosomes.
Hence, option C is correct
Soil creep is the downward movement of soil, on a slope, caused by the force of gravity. A slow deformation of soil material over a prolonged period of time, from pressure and stress. Creep occurs when the friction from materials resisting gravity move against each other. Slope is a key cause of soil creep.
