Answer:
The correct answer is - all of the above.
Explanation:
If the cold and warm front collide the warmer air rises and colder air moves to the bottom due to the density of warm air is less than cold air which creates a front that is the boundary front of both fronts.
It forms a new front called an occluded front. The occluded front causes heavy precipitation, strong winds. and snow sometimes. In low pressures it also caused tornadoes.

‘Family planning’ is a broad term that includes any measures taken to responsibly prevent pregnancy (birth control, contraception, planning, abortions, permanent infertility procedures, etc.).
Birth control, however, is specifically designed to intervene in a woman’s natural hormones to drastically reduce the possibility of pregnancy (much like contraception)
Answer:
The three genes in coupling are in repulsion.
Explanation:
Coupling happens when the dominant alleles and the recessive alleles are on the same homologous chromosome, while the repulsion happens when one chromosome has one dominant allele and one recessive allele and another homologous chromosome also has dominant and recessive alleles.
If the progeny has:
nb+ ls+ a/nb ls a ⇒ nb+ ls+ a
nb ls a+/nb ls a ⇒ nb ls a+
Where nb+ ls+ a is the dominant alleles and nb and nb+ is in middle.
ls+ nb+ are on the same chromosome (both dominant)
ls nb are on the same chromosome (both recessive)
ls nb, these two are in coupling with each other, but ls+ and a are on the chromosome and ls+ or nb+ are dominant, while nb+ and a are recessive on form a, thus, ls and nb, they are in repulsion with a.
