Because they were passed down from a common ancestor, homologous structures are those found in related organisms that are comparable. These structures might or might not serve the same purpose in their offspring. The hands of various different mammals are depicted in the figure below. The basic skeletal structure of each is the same.
What is offsrping?
a person, animal, or plant's offspring or progeny is the result of reproduction. Parental transmission of the illness can affect children, a human or animal's direct offspring; a person born of parents gave birth to a lone child.
Creating offspring is considered reproduction. Reproduction comes in two basic forms: sexual reproduction and asexual reproduction. A sexually reproducing creature integrates the genetic material of both parents to create a genetically distinct individual. Asexual reproduction involves the self-replication of one parent to create genetically identical kids.

The correct sequence of events is : C,D,B,A.
Iron rich magma in the earth's core heats up because of radiation and the pressure exerted by the other layers of the earth. This heat in the crust trigger convection currents in the mantle. The magma closest to the core will be hotter and therefore less dense than other layers. Being less dense the layer will rise towards the crust, eventually becoming cooler and sinking back down in a circular motion.
The continued circular motion creates electric currents which then generates the magnetic field.
There are 4 factors for evolution: mutation, gene flow, genetic drift, and natural selection. Natural selection is the strongest
The biosphere is most responsible fir the increases of global warming
The mass number is the sum of the number of protons and number of neutrons the atom has.
So, we can write the equation as:
x + 20 = 40
x = 20 neutrons.
