Answer:
Option (4)
Explanation:
The earth is comprised of numerous lithospheric plates. This lithosphere is comprised of dozens of major plates and a few minor plates. These plates are constantly in motion over the less dense asthenosphere layer where the rocks tend to flow during deformation. This plate motion takes place due to the creation of convection current in the mantle region as a result of which the plates move under the influence of uprising magma. These currents are formed because of the heat supplied from the core of the earth.
Some of the major plates are Indo-Australian plate, North American Plate, South American plate and the Pacific plate.
Some of the minor plates include the Cocos plate, Nazca plate, and Caribbean plate.
Thus, the correct answer is option (4).
Answer:
antibodies are produced in response to infection and that these antibodies are designed to specifically target particular antigens and bind tightly to them.
The correct answer is option B, 50%
Let us take the following case:
Genotype of heterozygous parent - (Aa)
Genotype of homozygous parent – (aa)
Allele I - (Aa)
Allele II – (aa)
The cross between the two is shown below:
Aa X aa
Aa, Aa, aa, aa
There are 50 % Aa, and 50 % aa allele.
Thus, the allele I (Aa) is 50 %.
