Answer:
Option B, Divergent Boundary
Explanation:
The tectonic plates moving around form the divergent boundary and at this boundary magma from inside the earth rises to form new crust on the lithosphere beneath the water. Most of the divergent plate boundaries are present below the water where they form oceanic spreading ridges (submarine mountain ranges). The process of formation of oceanic spreading ridges is volcanic.
Hence, option B is correct
Answer:
D. the 23rd pair of chromosomes
Explanation:
Humans have a total of 23 pairs of chromosomes. Out of a total of 23 pairs, 22 pairs are autosomes. Autosomes are the chromosomes that carry the genes for all the genetic traits but are not involved in the sex determination of the individuals.
The 23rd pair of chromosomes in humans is of sex chromosomes as these chromosomes carry the genes to regulate the gender of the individuals. A human female has two copies of the X chromosome as sex chromosomes while human males have one X and one Y chromosome as their sex chromosomes. The Y chromosome carries "SRY" gene that codes for testes determining factor and regulates the development of testes in the embryo.
