Predict how the synaptic configurations of homologous pairs of chromosomes might appear when one member is normal and the other member has sustained a deletion or duplication.

a.
The deletion or duplication of any chromosome region will most likely be detrimental for its synapsis with a normal chromosome.

b.
There will be point-for-point pairing in all sections of the chromosome located between the centromere and the region of deletion or duplication. The rest of the chromosome will show no pairing.

c.
There will be point-for-point pairing in all sections of the chromosome located between the end of the chromosome and the region of deletion or duplication. The rest of the chromosome will show no pairing.

d.
There will be point-for-point pairing in all sections that are capable of pairing. The section that has no homolog will loop out to form a deletion or compensation loop.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

what school and grade?

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
